Is it possible to paint ondulin and with what? Is it possible to paint a cherry-colored ondulin roof brown? Ondulin roof painting

Experienced roofers often prefer ondulin, a roofing material that is lightweight and durable. But he 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:

1. Light weight. A sheet of material weighs only 6 kilograms, which makes it lighter compared to other types of roofing products, so installation requires just a simple installation. rafter frame and lathing. The weight of ondulin makes it possible to lay a new coating without dismantling the old one.
2. Strength. This property is due to the presence of a fibrous structure in the material. Ondulin is able to withstand snow load size 300 kg/m².
3. Waterproof and low water absorption. The material is resistant to water. It does not absorb moisture due to the presence of bitumen impregnation.
4. 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.
5. 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.
6. Environmental Safety. The components used for the production of ondulin do not adversely affect human health and environment, and this circumstance distinguishes it from other roofing products, which may contain harmful impurities.

Negative effects of ultraviolet radiation - loss of color

A significant disadvantage of ondulin is its instability to ultraviolet radiation. When hit sun rays onto the roofing surface of this material The pigment that gives the coating color 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 pigment leads to a decrease in decorative qualities coatings - 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:

1. Economy class. When manufacturing roofing products, sheets are painted before being impregnated with bitumen. This method allows you to hide under protective layer destructible pigment. As a result, ondulin retains its color for 6–8 years and is much cheaper.
2. 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 options color design. 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 on construction market there are few suitable options.

As a result of the limited supply of coloring compositions for ondulin, the following are used:

1. "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 high price, this paint is more expensive than similar compositions.
2. Acrylic paint. It is made on the basis of water-dispersed polyacrylate. When dry after application acrylic paint a film is formed on the roofing surface, insoluble in water and similar in its 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. Usage acrylic composition allows you to paint the roof in any color.
3. Bitumen mastic. She is also called " liquid rubber" Due to the compatibility of the compositions, mastic is best choice How to paint ondulin if 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 included in color palette bitumen mastic, 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.

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. Different from others brands 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 additional outer layer, allowing 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 scheme: 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.
• For achievement 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 you to apply the mixture 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 big choice 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.
• Has a fairly large selection of colors.
• Withstands temperature regime from -50 to +60°C.
• Careful preparation of the area and cleaning it of contamination 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. For completely dry it takes 2-4 hours, 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 performance characteristics the same as 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 special conditions manufacturers.

3. To obtain a specific color, you need to mix the mixture with a color scheme. 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.

In the annotation on roofing material "Ondulin" it is said that during its manufacture the sheets are painted before being impregnated with bitumen, which makes their color resistant to ultraviolet radiation. In addition, luxury class Ondulin is painted again after impregnation. Thanks to this, the color of the sheets roofing material this variety becomes brighter and more resistant to ultraviolet rays, therefore Euroslate retains its original color.
However, in practice, it happens that the color of sheets fades as a result of exposure to ultraviolet radiation and changes its “original color” to faded. But what they can be additionally painted with to give them an attractive appearance is not mentioned in any instructions or anywhere at all. There are also no clear recommendations and advice from managers and dealers supplying this roofing material to the Russian market.
My opinion is that the main properties that roofing paints should have are weather resistance and resistance to ultraviolet radiation, as well as resistance to corrosion. Therefore, it is best to paint roofs with special industrial roofing paints developed by leading manufacturers of paint and varnish products.
Since “Ondulin” is a roofing material, in the manufacture of which bitumen impregnation is used, it should be used for painting paints and varnishes for roofing coatings based on bitumen. For example, “Kilpi” is a matte roof coating based on a modified acrylate dispersion from the Finnish manufacturer Tikkuril. The paint is used for painting roofs made of roofing felt, bituminized fiber boards, fiber cement and painted with bitumen paint steel roofs, not covered with rust, as well as concrete blocks. The coating has good weather resistance and can be used in industrial and marine climates.
Color coloring selected from Tikkurila company catalogs, such as “Paints for metal roofs" and "Paints for external works", as well as in the "Tikkurila Facade" range.
Paint consumption is 250-500 ml/m2 for a two-layer coating of bitumen surfaces. “Kilpi” is applied with a paint brush, it can also be applied with a roller, but after that it is necessary to additionally finish the surface with a brush.
Drying time at 23ºC and relative humidity air 50% – up to 2 hours. If necessary, finishing painting is done the next day. Drying slows down as the relative humidity increases and the temperature decreases. The coating is elastic and does not become brittle in cold weather, and also withstands the effects of rainwater and dew.
One reminder will not be superfluous - the roof must be thoroughly washed and cleaned of dust, branches and other debris.

To have an accurate answer to this question, you need to know:

1. firstly, what is it made from, so as not to use paints based on a solvent that Ondulin can dissolve and therefore destroy;
2. secondly, what is the degree of adhesion (adhesion) of the molecules of two materials - specific paint and Ondulin;
3. thirdly, how environmentally friendly the painting material is, in order to be sure that rainwater from the roof can continue to water flowers and tomatoes, as before before painting;
4. fourthly, how resistant the paint is to the ultraviolet radiation of the summer sun.

Properties and composition of Ondulin roofing

The material from which European roofing is made consists of bitumen (a petroleum product), cellulose fibers (wood), minerals (mainly silicon-based), temperature-hardening resins (essentially, technical rubber), mineral pigments-dyes.

In the process of producing this composite roofing material, cellulose fibers are saturated with a colloidal solution of pigments, crushed rubber and minerals in bitumen at high temperature harden. Therefore, Ondulin has the following useful consumer properties:

1. Low wettability and insolubility in water.
2. Flexibility.
3. Not tall specific gravity material.
4. Resistance against microorganisms and fungi (bitumen is an ideal antiseptic).
5. High technology of installation.

The presence of these excellent construction and consumer qualities of Ondulin at the same time means that good adhesion (adhesion) with it from most types of paint cannot be expected, because aggressive solvents simply destroy organic compounds, from which Ondulin consists.

Water-dispersed polyacrylate (acrylic paint)

And it turned out that the easiest way to paint bitumen Ondulin is with water-dispersion paints. True, modern paint and varnish products are fundamentally different from classic ones. Copolymers and polyacrylates with short molecules dry to form stable, water-insoluble solids that have the properties of a liquid. In this they are similar to bitumen. That is, when two solid quasi-liquids come into contact through a layer of water, their molecules enter into dispersion bonds and interpenetrate.

And bitumen-rubber roof surfaces, which are problematic to paint with compositions based on aggressive solvents, can be easily coated with compositions that have similar properties to conventional water-based paints.

New products from Ondulin

It should be noted right away that Ondulin roofs practically do not change their color in the sun, since solid pigmented mineral (inorganic) particles cannot burn out. Ondulin products lose the freshness of their color due to contaminants that are absorbed into it upper layer due to the presence of water-soluble acidic compounds in industrial dust. They are difficult to wash off, especially not with water. And why do this if easier the roof repaint and refresh.

For these purposes, the company that produces Ondulin created a special water-dispersion paint with a silicone-acrylic composition. Drying, this quasi-liquid has high properties adhesion (adhesion) with a very large list of synthetic and natural materials. Acrylic itself and silicone inclusions are related in nature to the components that make up Ondulin. Therefore this new paint and named Ondupaint.

As in Ondulina, Ondupane's color is determined by pigmented mineral inclusions that are not subject to decay under the influence of ultraviolet radiation our daylight. After drying, which occurs at positive temperatures in no more than 4 hours, a durable and water-repellent film is formed on the surface to be painted. It is also elastic and retains this property in wide aisles. negative temperatures(up to – 50*C).

Working with Ondupaint is easy. It is ready for use immediately after leaving production. It can be applied to the roof surface with a spray gun, roller or brush. Depending on the condition of the surface to be painted, Ondupane is consumed in the range of 100 – 150 g/m2. After drying, if necessary, you can paint it a second time, eliminating flaws. There will be no noticeable differences in the color of the areas.

The Onduint company produces the same standard colors as Ondulin, that is: green, brown and red. The paint is universal in its application. It can be used to cover not only Ondulin, but also metal, stone, brick, slate, protecting them with a water-repellent thin layer.

The manufacturer gives a 5-year warranty on its paint, but in practice it lasts much longer. So today the question is - how to paint Ondulin for the rabbit? – disappeared.

- roofing material characterized by lightness. Its installation does not require preliminary complex calculations and may well be performed by a person who is not very familiar with such a procedure.

To create a roof from ondulin, it is advisable to immediately purchase additional elements and fasteners.

All of them must be manufactured by the same manufacturer and have the same color scheme with sheets of ondulin. This article will provide some tips for installing an ondulin roof.

Ondulin in present time is one of the most popular roofing materials. Ondulin roofs are now found everywhere and there is an explanation for this.

Ondulin material is inexpensive, has excellent quality, good strength and attractive appearance. However, some consumers complain that over time, ondulin sheets change color, fading in the sun.

In this article we will try to figure it out, what compositions are best to paint ondulin so that it does not change its color over a long period of use.

The instructions for ondulin say that coloring with mineral components occurs before the cellulose fiber is impregnated with a bitumen composition. A ondulin sheets High Quality are painted even after impregnation with bitumen compounds.

This makes the roofing material extremely resistant to ultraviolet rays and ensures long-term preservation of the original shade.

But during actual operation ondulin very often loses its original saturated shade, becomes dull and faded. Manufacturers of ondulin sheets do not say what to do in this case.

But people who have already encountered a similar problem, it is advised to stain ondulin, choosing a high-quality coloring composition.

Paint for ondulin must have high durability to unfavorable atmospheric phenomena, corrosion and ultraviolet rays. It is best to purchase industrial paint for roofing to paint ondulin.

This paint should be made on the basis of bitumen– this will ensure good adhesion. For a two-layer coating of an ondulin roof you will need approximately 250-500 ml/m2 of paint. Apply the coloring composition paint brush or with a roller, having first thoroughly cleaned the roof of debris and dust.

When working with ondulin roofing material, a craftsman often needs to cut a single sheet into several small elements. For this procedure you need special tool. Many experts advise using for cutting ondulin with a hacksaw for wood.

If it is necessary to cut ondulin sheets quickly- you can use special electric tools, the range of which has recently expanded significantly.

Ondulin is generally considered flexible material , so there are no problems with cutting it. The only difficulty is to choose a tool that would provide an even cut edge.

The best option, according to many builders, V in this case is a manual circular electric saw. It not only cuts ondulin sheets quickly and efficiently, but is also easy to clean. To clean the teeth of such a saw, you just need to cut a piece of wooden board with it.

A hand-held power saw helps cut ondulin sheets along and across, while obtaining a perfectly even cut edge. But the master does not always have such a tool at hand. An alternative circular saw There will be a grinder or a jigsaw.

For longitudinal cutting of ondulin sheets can be used construction knife . They make an incision on the front side of the material, then the sheet is bent in half and completely cut into two parts.

A hacksaw is suitable for cross-cutting ondulin.. When using it, the problem of ondulin particles sticking between the cloves also arises. In this case, professionals advise periodically lowering the hacksaw into deep container with cold water.

When installing the roof necessary Special attention pay attention to fasteners. The duration of operation depends on how correctly it is performed. roofing covering and the entire roof.

The main fastening element for ondulin sheets are nails and screws. There are two types of nails for ondulin: with heads made of polyvinyl chloride and polypropylene. Both of these types have the following characteristics:

• Not susceptible to ultraviolet sunlight;
• They are highly resistant to adverse weather conditions and precipitation;
• Creates excellent anti-corrosion protection;
• Provides tightness to the under-roof space.

The basis of the nails used to fasten ondulin sheets are the same organic fibers. Color solutions these fastening elements are presented in four standard colors: green, brown, black and red.

The shades of the nails completely match the color roofing material, and this allows you to do general form finished roof aesthetically attractive.

Nails for fastening ondulin are made of carbon steel, and they are covered on top special solution zinc providing a good anti-corrosion effect.

The nail heads for ondulin have enough big size, which allows you to securely fix the material on the surface of the base. These fasteners can have different diameters heads and shanks, different nail lengths.
