The question of choosing a roof for a roof is a key question that arises in almost all people when building a house. After all, the roof not only protects the home from weather hazards such as snow, rain, hail, scorching sun, but also gives the entire house beauty and uniqueness. Currently, the choice of building materials is so extensive that it is possible to create a roof of almost any shape and any color - it all depends on the wishes of the customer, his financial capabilities and the designer’s imagination.
Today one of the most popular roofing materials is ondulin.
Today one of the most popular roofing materials is ondulin. Roofs covered with ondulin can be found in almost any cottage community. Ondulin, also known as Euroslate (the name “ondulin” came to us from the name of the manufacturer of this material in Europe), is a corrugated sheet of cellulose fiber and various mineral additives, impregnated with bitumen. Of course, ondulin, like any other material, has its advantages and disadvantages.
Most often associated with its unstable appearance, namely, color fading in the sun.
Therefore, in this article we will try to answer the question of how to paint ondulin, since this is one of the main problems in the roof restoration process. But first of all, let's look at the main advantages and disadvantages of this roofing material.
The main advantages and disadvantages of ondulin
The main advantages of ondulin include the following:
- environmental safety - ondulin does not contain substances harmful to humans and the environment;
- high level of sound insulation;
- no condensation if installed correctly;
- resistance to corrosion and chemicals;
- biological stability - the material does not rot, is resistant to bacteria and fungi;
- low water absorption;
- long service life - about 50 years;
- ease of transportation and installation due to the light weight of the material.
Of course, in addition to all the above advantages, ondulin has some disadvantages:
- flammability of the material;
- limited selection of colors;
- color instability due to fading in the sun.
Very often, house builders refuse to choose ondulin precisely because it quickly loses its appearance as it fades in the sun. But for many this is not a significant problem, because this roofing material can be painted.
Ondulin roof painting
The annotation for ondulin contains information that when producing this material, the sheets are painted before being impregnated with bitumen. This is done so that the color of the material is resistant to ultraviolet rays. And luxury class ondulin can also be painted after bitumen impregnation. Thus, Euroslate can retain its original color for a very long time.
The best tool for cutting ondulin is an ordinary wood saw.
But in practice, it very often happens that the color of ondulin under the influence of natural phenomena fades and becomes faded and ugly. How to act in such situations is not indicated in any instructions for the material. And not a single manager or dealer specializing in ondulin will give clear recommendations and advice on this matter. But, nevertheless, ondulin can be painted; some people practice it and share their experience in this difficult matter.
First of all, you need to choose the right paint. It must be weatherproof and resistant to UV rays and corrosion. It is best if ondulin is painted with a special industrial roofing paint made by leading manufacturers of paint and varnish products.
Due to the fact that ondulin is a roofing material made using bitumen, paint must be chosen based on bitumen. For example, the Finnish manufacturer Tikkurila offers a matte Killi coating for bituminized fiber boards, fiber cement, roofing felt, etc. This coating is weather-resistant, so it can be used in marine climates.
The paint color can be selected from Tikkurila catalogs. Paint consumption – 250-500 ml/m2 for 2 layers of paint. To apply the Killy coating, use a paint brush or roller. The paint dries at a temperature of 23ºC for about 2 hours. If the air is too humid, the paint will take longer to dry. This coating is very elastic, does not crack in frost, and is resistant to water. It would not be amiss to remind you that before painting the roof must be thoroughly washed and cleared of branches and debris.
Painting a roof is quite a tedious task and requires a lot of effort to achieve the desired result. Painting of ondulin can be done either independently or with the help of external specialists. But it is best to initially approach the issue with special responsibility and seriousness. Very often, ondulin is counterfeited, and it is the counterfeit that quickly loses its original appearance. Thus, carefully study the manufacturers in order to avoid the procedure of repainting the roof later. In any case, the choice is always yours! Good luck!
When choosing materials for roofing, developers give preference to inexpensive and durable ones, such as ondulin. It is in high demand, but it also has certain disadvantages. One of them is gradual fading in the sun. As a result, the question arises of how to paint ondulin if it is faded.
The sheets attract with a variety of shades and rich colors. They differ from other brands in quality and high performance characteristics. On the front side there is a marking in the form of the inscription Onduline.
According to the specifics of production, after making corrugated sheets, they are painted using a palette of 4 colors, and then “sealed” by treating them with a bitumen composition with the addition of polymers.
- For economy class, an additional outer layer to protect and preserve color is not provided. Ondulin fades over time and its color fades. It becomes especially noticeable after 5-6 years of operation.
- Lux after coating with bitumen composition is repainted. This maintains brightness for up to 15 years, but significantly increases the cost.
The ability to paint roofing material a second time provides a chance to protect it from subsequent fading and leakage. This allows you to renew the roof, change its color, give it the desired degree of dullness and decorativeness, and increase its service life by several years.
Overview of suitable paints
The manufacturer produces roofing sheets using a four-color range: red, brown, green and black. When onduline begins to fade, it becomes dull and unsightly. Over time, bitumen stains may appear on its surface.
The paint was developed by the same company that made the sheets.
- The basis of this high-tech product is an acrylic-silicone composition with additives that make the paint resistant to UV rays and weathering.
- Ondulin sheets can only be painted at air temperatures from +5 to +30°C.
- It is sold completely ready for use, but when thickening it is diluted with water.
- To achieve the desired result, at least 2 coats must be applied. The second time the treatment should be performed 4 hours after the first layer.
- The consistency allows the mixture to be applied with a brush, roller or spray. In the latter case, the need does not exceed 130-150 g/m2.
If you follow the rules specified in the instructions, the manufacturer provides a 5-year warranty.
The Finnish company Tikkurila produces acrylate paint. It can be applied to sheets that contain bitumen.
Highly valued for its elasticity at temperatures below zero degrees and a large selection of colors. Service life guarantee – 6-7 years.
3. Chief technologist.
Rubber alkyd-urethane paint produced by the domestic company Novbytkhim is designed for protective and decorative painting. Has a wide scope of application. Before use, stir and adjust to the desired consistency by adding water.
- Resistant to negative environmental influences, cracking, wear-resistant, does not fade.
- It has a fairly large selection of colors.
- Withstands temperatures from -50 to +60°C.
- Careful preparation of the area and cleaning it of contaminants is required. Sand previously painted areas until matte.
- Painting can only be done in dry weather, with humidity not exceeding 80% and temperatures from +10 to +30°C.
- Application is possible in any way available to the performer. It takes 2-4 hours to dry completely, 2-3 layers are needed. Drying the layer is 60 minutes, consumption is 250-300g/m2.
The guaranteed operational period, subject to storage and use conditions, is from 2 to 4 years.
Paint for ondulin will increase its durability several times, but you need to take into account that subsequently this action will have to be performed at least once every three years.
1. The selected mixture must have the same performance characteristics as the roofing covering, not only improving the appearance, but also increasing moisture resistance.
2. The paint should dry no more than 3-5 hours. When applying several layers, the next one is placed after the previous one has completely dried. The exception is special conditions of manufacturers.
3. To obtain a specific color, you need to mix the mixture with the color. It is advisable to use ingredients from the same manufacturer.
4. Before treatment, ondulin roofing must be cleaned, dried, and, if necessary, primed.
5. Primers are selected in accordance with the instructions for the specific composition and are applied in 1-2 layers.
6. Depending on the type of coating, sheets are:
- matte, rough to the touch, painted with acrylic composition;
- glossy, with a bright surface obtained by adding silicone.
7. Ondulin is made using bitumen, so it is better to choose paint with a bitumen base.
The color scheme used by the manufacturer was not chosen by chance. Red, brown, green and black shades harmonize with almost any surface shade.
Before starting the process, you must read the instructions, since failure to follow the technology can cause swelling and premature shedding of the paint.
Experienced roofers often prefer ondulin, a roofing material that is lightweight and durable. But it has one significant drawback - over time it begins to fade under the influence of ultraviolet radiation. Painting ondulin allows you to preserve the appearance of the roofing surface.
Characteristics of ondulin
In 1944, a French company began producing ondulin. Initially, this material was intended to eliminate leaks in roofs covered with slate, tiles or corrugated sheets. Over time, ondulin from the manufacturer of the same name became an independent product. This type of Euro slate is inexpensive, practical, and looks quite attractive on the roof.
This material is sold in the form of rectangular sheets with a size of 205x305 centimeters and a wavy profile. It is produced exclusively from natural raw materials:
- purified cellulose fibers;
- petroleum bitumen;
- natural pigments;
- various modifiers.
Advantages of an ondulin roof
The popularity of using ondulin is explained by a number of its characteristics:
- Light weight. A sheet of material weighs only 6 kilograms, which makes it lighter compared to other types of roofing products, so installation requires a simple rafter frame and sheathing. The weight of ondulin makes it possible to lay a new coating without dismantling the old one.
- Strength. This property is due to the presence of a fibrous structure in the material. Ondulin is able to withstand a snow load of 300 kg/m².
- Waterproof and low water absorption. The material is resistant to water. It does not absorb moisture due to the presence of bitumen impregnation.
- Long service life. Ondulin is able to withstand 25 cycles, during which it is first frozen and then thawed, without changing its structure or losing its original properties. According to the manufacturer's warranty, the service life reaches 15 years. If the coating is properly cared for, it will last at least 30-40 years.
- Resistance to microorganisms. As you know, ondulin is impregnated with petroleum bitumen, which is a powerful antiseptic and for this reason a roof with such a coating cannot be damaged by fungus and mold.
- Environmental Safety. The components used for the production of ondulin do not negatively affect human health or the environment, and this circumstance distinguishes it from other roofing products that may contain harmful impurities.
Negative effects of ultraviolet radiation - loss of color
A significant disadvantage of ondulin is its instability to ultraviolet radiation. When sunlight hits the roofing surface of this material, the pigment that gives color to the coating begins to deteriorate.
As a result, ondulin becomes dull and faded, but the most unpleasant thing is that this process occurs unevenly. As a result, the destruction of the pigment leads to a decrease in the decorative qualities of the coating - the appearance of the roof deteriorates. But is it possible to paint ondulin?
Two types of this material are produced, which differ in coloring technology:
- Economy class. When manufacturing roofing products, sheets are painted before being impregnated with bitumen. This method allows you to hide the destructible pigment under a protective layer. As a result, ondulin retains its color for 6–8 years and is much cheaper.
- Luxury class. During the production process, products are subjected to a dyeing procedure 2 times. The first time paint is applied to them before treating ondulin with bitumen, and the second time after. The material is able to maintain color saturation for 10-15 years, but the use of an additional layer of paint increases the cost of the product.
Another disadvantage of ondulin is the small number of color options. The material is made in only four shades - black, brown, red and green. The limited color palette forces many owners of private houses to think about a solution to the problem of how to paint an ondulin roof.
Choosing paint - what is better to paint
Such a problem as color loss by ondulin can be easily dealt with. When the roofing covering finally loses its color and becomes dull, its sheets are coated with special coloring compounds that improve its appearance and at the same time increase the moisture resistance of the roof.
Ondulin paint must have properties similar to those of the coating in order to withstand adverse climatic influences throughout its entire service life. But there are few suitable options on the construction market.
As a result of the limited supply of coloring compositions for ondulin, the following are used:
- "Ondupaint". The paint is produced specifically for painting this material based on silicone and acrylic. After drying, a durable film is formed on the roof surface. Since this paint is produced by the ondulin manufacturer, compatibility is guaranteed. But the Ondupaint color palette is also limited to 4 standard shades. It takes only 4 hours for the paint to dry completely, and its service life is at least 5 years. The disadvantage of this option is the high cost; this paint is more expensive than similar compositions.
- Acrylic paint. It is made on the basis of water-dispersed polyacrylate. When drying after applying acrylic paint, a film is formed on the roofing surface, insoluble in water and similar in properties to bitumen. Its cost is cheaper than Ondupaint, but it lasts only a few seasons. The advantage of this option is the huge selection of colors. The use of acrylic composition allows you to paint the roof in any color.
- Bitumen mastic. It is also called “liquid rubber”. Due to the compatibility of the compositions, mastic is a better choice than painting ondulin if it is necessary to renew the roofing. When used, a durable film is formed on the surface of the material that resists atmospheric influences. A bitumen-based paint composition is more expensive than acrylic paint, but cheaper than Ondupaint. Its service life is approximately 3 years. All shades that are included in the color palette of bitumen mastic are matte. The composition dries quickly, only 2-3 hours.
To obtain optimal results, the roofing surface must be properly prepared. First, the stingray is cleaned using water, sometimes this requires a brush with plastic bristles. After drying, the ondulin surface is primed and painted in one or two layers.
Ondulin is one of the most common roofing materials, which has a long service life and attractive appearance. Corrugated bitumen sheets are positioned as practical to use and do not cause installation difficulties. They are made from modern raw materials using cardboard and cellulose fibers, polymer canvases, which explains their widespread use. Their only weak point is the loss of color under the influence of ultraviolet rays (burnout). To keep the roofing material presentable, you will need ondulin paint and some simple work.
Is it possible to paint ondulin
It is possible to paint ondulin sheets in order to return them to their previous appearance or completely change the design. It is important to use the appropriate paint from trusted manufacturers. Instability to the negative effects of sunlight often forces owners of ondulin roofs to periodically paint.
Such an unpleasant moment as color fading occurs as a result of the destruction of the pigment that gives the desired color to the coating. Not only the dullness and fading of ondulin is its disadvantage, but also the unevenness of this process. Such a roof on a building loses its decorative qualities.
There are 2 types of roofing products on the building materials market, differing in coloring technology:
Attention! The high popularity of ondulin sheets ensures its safety and environmental friendliness. All components of the material do not emit any toxic substances and do not harm the environment or human health. It is this factor that distinguishes ondulin from other roofing materials containing harmful impurities.
Among the positive characteristics of ondulin are:
- Relatively light weight - 6 kg in one sheet. Due to the lightness of the material, for arranging the roof it is enough to erect a simple rafter structure and sheathing. It is noteworthy that you can use ondulin sheets without resorting to dismantling the old coating.
- High level of strength. This parameter is provided by the fibrous structure of the material. The sheets can withstand snow loads of up to 300 kg/m2.
- High degree of resistance to the negative effects of water. Bitumen impregnation prevents the roofing material from absorbing moisture.
- Long period of operation - up to 25 years. The advantage of ondulin is the preservation of its original working qualities under conditions of sudden temperature changes. The manufacturer provides a product warranty of up to 15 years, and if you monitor the condition of the roof, this period can increase to 30-40 years.
- Resistance to fungi and mold. Petroleum bitumen used in impregnation has strong antiseptic properties, which does not allow pathogenic microflora to multiply.
How can you paint ondulin?
To return the roofing material ondulin to its original appearance, it is necessary to coat it with a special coloring composition. Correctly selected paint can improve the color and increase its level of moisture resistance. When choosing a composition for coloring, preference should be given to options with similar characteristics to those of ondulin. Among the suitable paints, the following are in demand:
- Ondupaint. This paint is designed specifically for painting bitumen sheets. This high-tech product is made on the basis of a silicone and acrylic mixture. The homogeneous suspension contains pigments and special components that are resistant to ultraviolet rays and precipitation. This homogeneous viscous liquid, after drying on the surface of the sheet, forms a durable film.
The undeniable advantage of this paint is the fact that it is produced by the same manufacturer as Ondulin. These two products are completely compatible. The only slight drawback of Ondupate is the limited color range - there are only 4 colors on the market: green, dark, red, brown. The drying time of the applied layer is 4 hours, and lasts for 5 years without loss of quality. - Acrylic paint. The main component of this paint is water-dispersed polyacrylate, which, after complete drying on ondulin, leaves a film resistant to external factors. Acrylic paint has similar properties to bitumen. Its advantage is its relatively low cost when compared with a specialized composition from the French manufacturer Onduline. The color retention period is only 2-3 years, which requires frequent use. Among the positive characteristics of acrylic paint, there is also a huge range of shades, which makes it easy to choose the best option.
- Bitumen mastic. Due to its similar composition, bitumen mastic is ideal for painting roofs made of ondulin sheets. Liquid rubber forms a thick, durable layer on the treated surface that effectively resists adverse environmental factors. If you compare the cost of bitumen mastic and acrylic paint, it will be somewhat more expensive, but in relation to Ondupate it will be cheaper. Liquid rubber lasts on the roof for 3 years. The color palette is quite varied. Drying time for bitumen-based paint is 2-3 hours.
Attention! To achieve the desired result, it is not enough to choose the right paint; you need to know the basic subtleties of the roof renovation process.
Before you start painting the roofing material, you need to carry out a set of preparatory measures. Do not allow particles of dust or various types of contamination to remain on the surface. They must be removed; the roof slope can be cleaned by using water and a brush with plastic bristles. When the ondulin sheets dry, it is recommended to prime them, and only after that apply 1-2 layers of paint. Spend mainly 250 ml of the selected composition per square meter of surface.
The necessary tools for the job will be: a roller, a brush or a spray gun. The optimal air temperature for applying paint to an ondulin roof should be no more than 20 degrees. The drying time of the first layer in this case will be 2 hours. If it is cool or high humidity, the drying time increases to 4 hours.
With the right approach and adherence to application technology, the coating has a high degree of elasticity. Even at sub-zero temperatures it does not crack and has a sufficient level of resistance to weather conditions.
Conclusion
Ondulin paint must have properties similar to the material itself in order to effectively withstand adverse environmental factors. It is also recommended to select primer and color from the same brand. Before use, please read and follow the manufacturer's instructions. Considering that painting the roof has certain risks to life, work should be carried out in compliance with safety regulations.

How to properly paint ondulin on the roof
Ondulin roofing materials are painted during the production process. Mineral pigments are included in the raw material, due to which the sheets are painted over the entire thickness and retain color throughout their entire service life.
Due to long-term exposure to ultraviolet rays, the pigment loses its original brightness, but most often the cause of color loss is dust clogging the small pores of the roof.
By painting the roofing yourself, you can return the roof to its original appearance or completely change its design. For this, branded acrylic-silicone paint Ondupaint or water-based acrylic paints for floor coverings are used.
Before purchasing materials, measure the roof area and check the paint consumption per 1 square meter. m. This will allow you to purchase the required quantity and avoid unnecessary costs.
Preparing the roof for painting
1. Remove foreign objects, old leaves and debris from the roof. Clean the ondulin from dirt. If necessary, wash the roof with water.
Advice. Clean with a stiff brush; do not use metal utensils. Ondulin cannot be cleaned with gasoline or white spirit.
2. Carefully inspect the coating for dents, chips and cracks. Minor roof repairs can be performed using bitumen sealant and Onduband Pro self-adhesive tape.
3. Before painting, the roof surface is coated with a primer. This is necessary in order to:
– strengthen the top layer of material;
– increase the adhesion strength of paint to the surface;
– reduce paint consumption.
Water-based acrylic primers are used as a base for acrylic paints.
Ondulin roof painting
1. Acrylic paints have a high viscosity, so they are applied with a brush with short, stiff bristles.
Applying acrylic paints using a sprayer is associated with certain difficulties. When choosing this method, seek help from professionals.
2. Painting is carried out in stripes from top to bottom, along the profile of the sheets. To prevent the joints of the strips from being noticeable, start painting from the north side of the roof.
3. If it is necessary to paint in several layers, each subsequent layer of paint is applied after the previous one has completely dried.
4. To obtain the desired color, the paint is mixed with a colorant for water-based acrylic paints.
In conclusion, a few tips:
– purchase primer, paint and color from the same manufacturer. Please consult the seller before purchasing;
– before using the materials, carefully read the instructions and strictly follow their requirements;
– working at height is associated with a risk to life, so strictly follow safety regulations.
How to properly paint ondulin on the roof
Over time, ondulin roofing may lose its original brightness and attractiveness. The reason for this is exposure to ultraviolet rays and dust clogging small pores. You can update or completely change the color of your roof using acrylic paints.
Is it possible to paint ondulin?
The question of choosing a roof for a roof is a key question that arises in almost all people when building a house. After all, the roof not only protects the home from weather hazards such as snow, rain, hail, scorching sun, but also gives the entire house beauty and uniqueness. Currently, the choice of building materials is so extensive that it is possible to create a roof of almost any shape and any color - it all depends on the wishes of the customer, his financial capabilities and the designer’s imagination.
Today one of the most popular roofing materials is ondulin.
Today one of the most popular roofing materials is ondulin. Roofs covered with ondulin can be found in almost any cottage community. Ondulin, also known as Euroslate (the name “ondulin” came to us from the name of the manufacturer of this material in Europe), is a corrugated sheet of cellulose fiber and various mineral additives, impregnated with bitumen. Of course, ondulin, like any other material, has its advantages and disadvantages.
Most often, the disadvantages of ondulin are associated with its unstable appearance, namely, with color fading in the sun.
Therefore, in this article we will try to answer the question of how to paint ondulin, since this is one of the main problems in the roof restoration process. But first of all, let's look at the main advantages and disadvantages of this roofing material.
The main advantages and disadvantages of ondulin
The main advantages of ondulin include the following:
Scheme of a roof covered with ondulin.
- environmental safety - ondulin does not contain substances harmful to humans and the environment;
- high level of sound insulation;
- no condensation if installed correctly;
- resistance to corrosion and chemicals;
- biological stability - the material does not rot, is resistant to bacteria and fungi;
- low water absorption;
- long service life - about 50 years;
- ease of transportation and installation due to the light weight of the material.
Of course, in addition to all the above advantages, ondulin has some disadvantages:
- flammability of the material;
- limited selection of colors;
- color instability due to fading in the sun.
Very often, house builders refuse to choose ondulin precisely because it quickly loses its appearance as it fades in the sun. But for many this is not a significant problem, because this roofing material can be painted.
Ondulin roof painting
The annotation for ondulin contains information that when producing this material, the sheets are painted before being impregnated with bitumen. This is done so that the color of the material is resistant to ultraviolet rays. And luxury class ondulin can also be painted after bitumen impregnation. Thus, Euroslate can retain its original color for a very long time.
The best tool for cutting ondulin is an ordinary wood saw.
But in practice, it very often happens that the color of ondulin under the influence of natural phenomena fades and becomes faded and ugly. How to act in such situations is not indicated in any instructions for the material. And not a single manager or dealer specializing in ondulin will give clear recommendations and advice on this matter. But, nevertheless, ondulin can be painted; some people practice it and share their experience in this difficult matter.
First of all, you need to choose the right paint. It must be weatherproof and resistant to UV rays and corrosion. It is best if ondulin is painted with a special industrial roofing paint made by leading manufacturers of paint and varnish products.
Due to the fact that ondulin is a roofing material made using bitumen, paint must be chosen based on bitumen. For example, the Finnish manufacturer Tikkurila offers a matte Killi coating for painting roofs made of bituminized fiber boards, fiber cement, roofing felt, etc. This coating is weather-resistant, so it can be used in marine climates.
The paint color can be selected from Tikkurila catalogs. Paint consumption – 250-500 ml/m2 for 2 layers of paint. To apply the Killy coating, use a paint brush or roller. The paint dries at a temperature of 23ºC for about 2 hours. If the air is too humid, the paint will take longer to dry. This coating is very elastic, does not crack in frost, and is resistant to water. It would not be amiss to remind you that before painting the roof must be thoroughly washed and cleared of branches and debris.
Painting a roof is quite a tedious task and requires a lot of effort to achieve the desired result. Painting of ondulin can be done either independently or with the help of external specialists. But it is best to initially approach the issue of choosing roofing material with special responsibility and seriousness. Very often, ondulin is counterfeited, and it is the counterfeit that quickly loses its original appearance. Thus, carefully study the manufacturers in order to avoid the procedure of repainting the roof later. In any case, the choice is always yours! Good luck!
How to paint ondulin: how to choose the right paint
How to paint ondulin? This is a question that many owners of a roof that has lost its original appearance have faced.
How can you paint ondulin at home?
For aesthetic reasons, I would like to have a light-colored roof. The problem is that the rafter system is designed for a light roof. How can you repaint ondulin sheets in beige or sand color with high quality and for a long time?
A new product has appeared on the construction market, from the Ondulin company, apparently the requests of consumers were heard, the paint is called “Ondupaint”
I understand that this option is not suitable for you.
The other options cannot guarantee anything, as they say, you will have to act at “your own peril and risk.” Ondulin clearly and unequivocally states that their products cannot be painted, the paint is applied before the sheets are impregnated with bitumen and this is a finished material.
If you haven’t purchased ondulin yet, then pay attention to “Lux” class ondulin; such sheets are painted twice, before impregnation and after.
You can try painting ondulin with mastic paint for slate, the paint is called “Vaksa” (VAKSA),
The only thing I can’t understand is why paint ondulin at all, the warranty on paint is 5 years, ondulin 50 years.
Instead of ondulin in this case, metal tiles would be better; they are easy to paint and there is a huge choice of colors.
From all that has been said, we can conclude: It is better not to paint Ondulin at all.
And it’s not entirely clear how you will move on a roof covered with ondulin; break through both the ondulin and the sheathing.
The surface for painting must be perfectly prepared; in outdoor conditions this is extremely problematic.
Friends painted ondulin, and three years later they replaced it with a new one.
There are a lot of fakes on the markets, it is important to buy high-quality ondulin, then problems with paint fading will not arise.
Painting ondulin is not an easy task, but it can be done (how long this coating will last depends on how carefully you prepare the coating for painting; on average, the coating will last three years, under favorable circumstances it can be longer, up to 5 years). There is a huge selection of paints on the market, but only one was made purely for ondulin - Onduline (Ondupaint). Therefore, when choosing paint, it is better, of course, to take industrial paint from leading manufacturers of paint and varnish products. When choosing, you need to pay attention to bitumen-based paint; it must be resistant to ultraviolet rays and corrosion, as well as weather-resistant.
As already noted, Ondupaint paint is produced for painting ondulin - this would be an ideal option, short of completely replacing the roofing. Tikkurila Kilpi paint based on bitumen (matte colors) is praised.
However, painting ondulin will cost you a pretty penny; the material is quite brittle, so not every master will agree to work with it in this way.
To paint an ondulin roof, you can use any acrylic-silicone water-based paint for the floor. The rules for preparing ondulin for painting are simple: clean the roof of dirt by pouring water on it and removing the dirt with a brush with plastic hairs (for example, a car brush). Treat the roof with a water-based primer and you can paint it.
