The modern building materials market offers roofing coverings for every taste and budget. Due to high competition, the consumer receives high-quality products for a reasonable price, which is constantly being improved and improved by the manufacturer. Recently, experienced roofers have “introduced fashion” to ondulin, a lightweight and durable roofing material for roofing. But, it has one unpleasant property - such a coating fades over time under the influence of ultraviolet rays. In this article, we will tell you how to paint ondulin in order to maintain the aesthetic appearance of the coating and extend the life of the roof.
Material trait
Ondulin refers to the products of the French company of the same name, which began producing this practical roofing material back in 1944. It was conceived as a means of rapid repair and elimination of leaks in roofs made of corrugated board, slate or tiles without dismantling the structure, which eventually turned into an independent coating. Ondulin is a rectangular page with a wavy profile, the size of which is 205x305 cm. This roofing material contains only natural components: purified cellulose fibers, natural pigments, modifiers and petroleum bitumen. The use of this material has the following advantages:
- A light weight. One sheet of ondulin weighs only 6 kilograms, which makes this material lighter than other roofing materials. That is why the quality, it is mounted on the most uncomplicated truss frame and crate. The lightness of ondulin allows laying a new coating without removing the old one.
- Strength. The fibrous structure provides ondulin with great strength, it can easily withstand a snow load of 300 kg / m2. A large load, at which the ondulin roof is deformed, forms 600 kg / m2, but, in most cases, it is not the roofing that is destroyed, but the crate and frame.
- Waterproof and low absorbency. Ondulin is highly resistant to the action of melt or rain water, it does not absorb moisture due to bituminous impregnation.
- Long service life. Ondulin withstands 25 cycles of freezing and thawing without structural transformation and loss of properties. The life of the material, guaranteed by the manufacturer, is 15 years. With proper care, a roof with such a coating will last at least 30-40 years.
- Microbial resistance. Oil bitumen, which is impregnated with ondulin, is the strongest antiseptic, so mold, fungus or moss will not break the roof of this material.
Note! The main advantage of ondulin is the safety and environmental friendliness of this material. All components included in the composition do not have a negative impact on the external environment or human health. This property distinguishes ondulin from other roofing materials that contain harmful impurities.
The action of ultraviolet
Perhaps the only drawback of ondulin, which sellers and manufacturers constantly warn customers about, is the instability of this material to the action of ultraviolet radiation. At a time when the sun's rays fall on the corrugated roof, the natural pigment that gives color to the coating begins to slowly break down. As a result, ondulin burns out over time, and the destruction of the pigment occurs unevenly. This process significantly reduces the decorative qualities of the coating, spoils the appearance of the roof. There are 2 types of material that differ in the staining method:
- Ondulin "economy" class. During the production of roofing in order to type the pages are coated with paint before impregnating with bitumen. This technology allows you to "hide" easily destructible pigment under a protective layer. Ondulin "economy" class is less resistant to ultraviolet radiation, on the basis of this, it retains color for 6-8 years, but it costs an order of magnitude cheaper.
- Ondulin luxury class. During the production of luxury roofing, the staining procedure is performed 2 times. First, the pages are painted before soaking with bitumen, and the second time - at the end. Due to the double layer of pigment, the material retains a rich color for more than 10-15 years, but you will have to pay for this additional layer of paint.
Fundamentally important! Another problem with working with ondulin is the limited range of colors in which this material is produced. The manufacturer produces roofing in 4 shades: dark, brown, green, red. The scarcity of the color palette makes many homeowners paint ondulin on their own through special formulations.
Choice of colors
Fortunately, the problem of ondulin fading is easy enough to deal with. To do this, at a time when the roofing material completely loses color, the pages are painted with special compounds. This coating enhances the appearance, and at the same time increases the moisture resistance of the roof. Paint for ondulin must have properties similar to it in order to withstand negative weather phenomena during the entire period of operation. But, the construction market offers not so many suitable options. For staining ondulin apply:
Skilled roofers say that in order to achieve optimal results when painting, it is fundamentally important to correctly prepare the surface to be treated. First of all, the roof slope is cleaned of dust and dirt with water. From time to time, some “water procedures” are not enough, then a brush with plastic villi goes into motion. After drying, the ondulin is primed, and then the paint is applied in 1 or 2 layers.
Video instruction
Often, ondulin is chosen as a roof for a roof, and many people are interested in the question of whether there is paint for ondulin and whether it can be painted. It will be much easier to choose the material of the required color, but if this is not possible, then the ondulin can be painted in the desired color. Acrylic, vinyl, epoxy-vinyl and other paints are suitable for these purposes. The only condition is that they dry for 2-3 hours.
The composition of ondulin: 1 - mineral dressing, 2 - bitumen, 3 - fiberglass, 4 - bitumen, 5 - silicon sand.
A roof covered with ondulin can be found very often, as it is very popular. This material got its name from one of its first manufacturers. It is a sheet that resembles slate in shape (but it is made of cellulose fiber with the addition of mineral components), after which it is impregnated with bitumen. The material is presented in a wide range of colors, but still, sometimes it is necessary to use ondulin paint to get the shade of interest.
Like any other building material that is used for roofing, ondulin has its advantages and disadvantages, before choosing it to cover the roof of your house, you need to familiarize yourself with them.
Main advantages and disadvantages
One of the main problems that may arise with this material, many experts say that over time, its color can change, and then when restoring the ondulin coating, the question arises of how to paint the ondulin. It happens that the quality of the coating is good, but the owner had a desire to change the look of his house, and he decided to change the color of the roof.
The advantages of this type of coverage:
- it does not contain harmful substances, so this material is environmentally friendly;
- it has good soundproofing characteristics, so the noise from the street does not enter the house;
- if the installation is done correctly, then condensation does not form on the surface;
- resistant to the action of various active elements and corrosion, does not rot and is not covered with fungus;
- has little water absorption;
- its service life is 50 years or more;
- It is light in weight, which makes it easy to transport and install.
Despite the presence of a large number of advantages, like any other building material, ondulin also has some disadvantages:
- the choice of its colors is limited;
- over time, in the sun, the material fades and loses its original color;
- combustibility.
Often it is the fact that the specified material loses its color over time that stops some people from choosing it as a roofing material. This will not be a problem for you if you know how to paint ondulin, after which it again acquires a bright color and will perform its functions with high quality for more than a dozen years.

Ondulin roof painting
If you look at the manufacturing technology of this material, you will see that the sheets are painted in the desired color before they are covered with a layer of bitumen. This is done in order to protect the sheets from fading under the action of sunlight, namely ultraviolet light.
Modern luxury material is dyed both before and after impregnation with bitumen, which allows it to retain its original color for a longer period of time.
To paint ondulin, it is necessary to take atmospheric paint, which is resistant to fading and corrosion.
Under the influence of natural factors, after a certain time, the color of ondulin becomes paler and duller, but this is not a very big problem, since the specified material can be dyed and restored to its original appearance.
To paint ondulin, it is necessary to take atmospheric paint, which is resistant to fading and corrosion. Since this material contains bitumen, the paint must also be taken on a bitumen basis, a special roofing paint is best suited.
When choosing a paint, it must be taken into account that it must be suitable for coating bituminous fiber boards, roofing material and similar coatings and must be weather resistant. An example is the well-known Finnish manufacturer Tikkurila, which offers Killy paint. The Ondulin company offers Ondupaint paint for these purposes, but you can choose any other manufacturer with suitable paint characteristics.
After you decide on the manufacturer of the paint, you need to choose the shade you need, for which you can use the catalogs. This coating must be applied in two layers, the paint consumption will be approximately 250 ml/m 2 .
To apply a coating on ondulin, you can use a roller, brush or spray gun. If it is warm outside and the temperature is more than 20 degrees, then 2 hours are enough to dry one layer of such paint. At lower temperatures or high humidity, the drying time may increase up to 3-4 hours.
A feature of such a coating is that it has high elasticity, so it will not crack even in severe frosts, and it is also resistant to precipitation. Before painting, do not forget to thoroughly clean the surface of debris and rinse it well, then allow to dry completely.
You can paint the roof yourself, but if you do not have free time and have extra money, you can hire specialists for this. When choosing a roofing material, you need to pay attention to its quality, since now there are a lot of fakes. If you purchase a high-quality ondulin, then it will serve as a high-quality roof covering for a long time and reliably, and you will not have to address such an issue as painting it.
When choosing a material for roofing, developers prefer inexpensive and durable materials, such as ondulin. It is in high demand, but it has certain disadvantages. One of them is gradual sunburn. As a result, the question arises of how to paint ondulin if it is burned out.
Sheets attract with a variety of shades and saturation of colors. They differ from other brands in quality and high performance. On the front side there is a marking in the form of the inscription Onduline.
According to the specifics of production, after the manufacture of corrugated sheets, they are painted using a palette of 4 colors for this, and then “sealed”, treated with a bituminous composition with the addition of polymers.
- For economy class, an additional outer layer that allows you to protect and preserve color is not provided. Ondulin burns out over time, its shade fades. It becomes especially noticeable after 5-6 years of operation.
- Lux after coating with a bituminous composition is re-painted. This retains brightness for up to 15 years, but significantly increases the cost.
The ability to paint the roofing material a second time gives a chance to protect it from subsequent burnout and leakage. This allows you to update the roof, change its color, give the desired degree of dullness and decorativeness, and increase the service life for several years.
Overview of suitable paints
The manufacturer produces roofing sheets using a four-color range: red, brown, green and black. When ondulin begins to fade, it becomes dull and ugly. Bituminous spots may appear on its surface over time.
The paint was developed by the same company as 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 an air temperature of +5 to +30°C.
- It is sold completely ready for use, but when thickened, it is diluted with water.
- At least 2 coats must be applied to achieve the desired result. The second time the treatment should be performed 4 hours after the first layer.
- The consistency allows the mixture to be laid with a brush, roller or sprayer. In the latter case, the need does not exceed 130-150 g/m2.
Subject to the rules specified in the instructions, the manufacturer gives a 5-year warranty.
The Finnish company Tikkurila produces acrylate paint. It can be applied to sheets containing bitumen.
Highly appreciated for its elasticity at temperatures below zero degrees and a large selection of colors. Service life guarantee - 6-7 years.
3. Chief technologist.
The rubber alkyd-urethane paint produced by the domestic company Novbytchim was developed for protective and decorative painting. Has a wide range of applications. Before use, mix and bring to the desired consistency by adding water.
- Resistant to the negative effects of the environment, 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 territory is required, its cleaning from pollution. Sand previously painted areas to a matt finish.
- It is possible to paint only in dry weather, at humidity no more than 80% and temperature from +10 to +30°C.
- Application is possible in any way available to the performer. For complete drying, 2-4 hours are required, 2-3 layers are needed. Drying of the layer is 60 minutes, consumption - 250-300g / m2.
Guaranteed operational period under the conditions of storage and use is from 2 to 4 years.
Paint for ondulin will increase its durability several times, but keep in mind that subsequently this action will have to be performed at least once every three years.
1. The mixture chosen should have the same performance characteristics as the roofing, 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 the special conditions of manufacturers.
3. To obtain a certain color, you need to mix the mixture with the color. It is advisable to use ingredients from the same manufacturer.
4. Ondulin roofing must be cleaned, dried, primed if necessary before processing.
5. Primers are selected in accordance with the instructions for a specific composition and are applied in 1-2 layers.
6. Sheets, depending on the type of coating, 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 a paint with a bituminous base.
The color scheme used by the manufacturer was not chosen by chance. Red, brown, green and black shades harmonize with almost any shade of the surface.
Before proceeding with the process, it is necessary to read the instructions, since non-compliance with the technology can cause swelling and premature shedding of the paint.
The question of choosing a roof for a roof is a key issue that arises for almost all people when building a house. After all, the roof not only protects housing from weather troubles, such as snow, rain, hail, scorching sun, but also gives the whole 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 fantasies.
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 settlement. 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 own advantages and disadvantages.
Most often 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, consider 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;
- lack of condensate, subject to proper installation;
- 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 low weight of the material.
Of course, in addition to all the above advantages, ondulin has some disadvantages:
- combustibility of the material;
- limited choice of colors;
- color instability due to fading in the sun.
Very often, homebuilders 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
Annotation to ondulin contains information that in the manufacture of this material, sheets are painted before impregnation with bitumen. This is done so that the color of the material is resistant to ultraviolet rays. And luxury class ondulin is also subject to coloring after bituminous 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 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 and 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 manufactured by leading manufacturers of paint and varnish products.
Due to the fact that ondulin is a roofing material made using bitumen, the paint must be chosen based on bitumen. For example, the Finnish manufacturer Tikkurila offers a matt Killi coating for bituminous fiber boards, fiber cement, roofing material, etc. This coating is weather resistant, so it can be used in maritime climates.
The color of the paint can be chosen according to the catalogs of the Tikkurila company. Paint consumption - 250-500 ml / m 2 for a coating in 2 layers. 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, then the paint will take longer to dry. This coating is very elastic, does not crack in cold weather, and is resistant to water. It will not be superfluous to recall that before painting the roof must be thoroughly rinsed, cleaned of branches and debris.
Roof painting is a rather tedious task, and in order to achieve the desired result, you need to make a lot of effort. Painting ondulin can be done both independently and with the help of involved specialists. But it is best to initially approach the issue with special responsibility and seriousness. Very often, ondulin is faked, and it is the fake 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!
Ondulin company produces roofing paints Onduvilla shingles, like any roofing material, periodically need maintenance. This usually consists of cleaning away dirt and old foliage, but in some cases the onduvilla roof requires minor repairs, including local painting. Ondupaint paint, produced by Ondulin, is best suited for this.2015-01-21T11:08:19+03:00
Unlike other roofing materials, Onduvilla tiles have a very important quality - for a long time. This durability is achieved using Onduvilla 3d's unique multi-layer coloring technology and the use of mineral dyes that are resistant to ultraviolet sunlight.
However, sometimes Onduvilla The need for local coloring arises in the following cases:
When sealing joints, junctions or damage, the repair composition is applied inaccurately and worsens the appearance of the roof;
During the repair of the defective area, a bituminous tile element of a different color was installed;
Roof safety elements, gutter systems, passage elements, bituminous rolled waterproofing, etc. need to be painted.
When performing such work, the best solution is to use Ondupaint paint manufactured by Ondulin. The paint is based on acrylic and silicone components, which provide resistance to extreme climatic conditions. The mineral dyes included in OnduPaint are resistant to sunlight, so the paint can be used as a UV protection coating.
OnduPaint is a homogeneous mixture that penetrates deep into porous surfaces and has excellent adhesion to various materials. When the paint dries, a hydrophobic frost-resistant film is formed, which provides additional protection for the roof in all weather conditions. Due to its water-repellent properties and resistance to dirt, the paint retains the brightness of colors for a long time and improves the aesthetic qualities of the roof.
Ondupaint is commercially available ready to use, does not require the use of any solvents, and is applied with a conventional brush or roller. For painting large surfaces, it is recommended to use an airbrush, this allows you to reduce material consumption.
Ondupaint's color scheme includes the same colors as Onduvilla: green, brown and red. The paint is supplied in cans of 2.1 l (2.5 kg), 3.75 l (4.5 kg), 7.5 l (9 kg) and 14.15 l (17 kg). If necessary, the paint is diluted with ordinary water, and its tone is corrected with a suitable color for water-based acrylic paints.
Outdoor painting work is carried out at a temperature not lower than +5 degrees, in dry weather. Paint consumption depends on the surface structure and is:
Onduvilla roofing, one layer - 130-150 gr/sq. meter (0.1 - 0.125 l / sq. meter);
Metal surface, one layer - 130 gr/sq. meter (0.1 l / sq. meter);
When painting ceramic, cement-sand tiles and other materials, the consumption depends on the porosity of the surface.
At an ambient temperature of +20 degrees, it takes 4 hours to dry the applied layer of paint.
