Who tried painting ondulin and with what. Tips for installing ondulin roofing. New products from Ondulin

Modern market building materials offers roofing coverings for every taste and budget. Thanks to high competition, the consumer receives high-quality products for reasonable money, which are constantly being 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 preserve the aesthetic appearance coating and extend the life of the roof.

Material trait

Ondulin is the name given 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 quickly repairing and eliminating leaks in roofs made of corrugated sheets, slate or tiles without dismantling the structure, which over time turned into an independent covering. Ondulin is a rectangular sheet with a wavy profile, the size of which is 205x305 cm. The composition of this roofing material includes only natural ingredients: purified cellulose fibers, natural pigments, modifiers and petroleum bitumen. The use of this material has the following advantages:

1. A light weight. One sheet of ondulin weighs only 6 kilograms, which makes this material lighter than others roofing coverings. That is why quality, it is mounted on the most simple rafter frame and lathing. The lightness of ondulin allows you to lay a new coating without removing the old one.
2. Strength. The fibrous structure gives ondulin greater strength; it can easily withstand snow load 300 kg/m2. The large load under which an ondulin roof is deformed is 600 kg/m2, but in most cases it is not the roof covering that is destroyed, but the sheathing and frame.
3. Waterproof and low absorbency. Ondulin is highly resistant to melt or rain water; it does not absorb moisture due to bitumen impregnation.
4. Long term operation. Ondulin can withstand 25 cycles of freezing and thawing without transforming the structure or losing properties. The service 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.
5. Microbial resistance. The petroleum bitumen with which ondulin is impregnated is a strong antiseptic, so a roof made of this material will not be damaged by mold, mildew or moss.

Note! The main advantage of ondulin is the safety and environmental friendliness of this material. All components included in the composition do not have any negative influence on external environment or human health. This property distinguishes ondulin from other roofing materials that contain harmful impurities.

Effect of ultraviolet

Perhaps the only drawback of ondulin, which sellers and manufacturers constantly warn customers about, is the instability of this material to ultraviolet radiation. At a time when the corrugated roof gets hit Sun rays, the natural pigment that gives color to the coating, begins to slowly deteriorate. As a result, ondulin fades over time, and the destruction of the pigment occurs unevenly. This process significantly reduces decorative qualities coating, spoils the appearance of the roof. There are 2 types of material, differing in the coloring method:

• Ondulin "economy" class. During the production of roofing sheets, the pages are coated with paint before being impregnated with bitumen. This technology allows you to “hide” an easily destructible pigment under protective layer. Ondulin "economy" class is less resistant to ultraviolet radiation, so it retains color for 6-8 years, but it costs an order of magnitude cheaper.
• Luxury ondulin. During the production of luxury roofing, the painting procedure is performed 2 times. The pages are painted first before being soaked in bitumen, and a second time after completion. Thanks to the double layer of pigment, the material retains its rich color for more than 10-15 years, but for this additional layer paint will need to be paid.

Fundamentally important! Another problem with working with ondulin is the limited color range, in which this material is produced. The manufacturer produces roofing coverings in 4 shades: dark, brown, green, red. Scarcity color palette forces many homeowners to paint ondulin themselves using special compositions.

Choice of colors

Fortunately, the problem of ondulin fading is quite easy to deal with. To do this, at a time when the roofing material completely loses its 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 conditions throughout the entire service life. But, construction market doesn't offer much suitable options

UV exposure

Unfortunately, such roofing material tends to fade, fade and lose its attractiveness over time. In addition, having a natural basis, ondulin does not have high biological stability. Already in the third year after installing the roof, moss and fungal colonies begin to multiply on its surface. And this leads to the formation of stains on the roof, the appearance of which becomes unpresentable.

Preparatory work, choice of paint

The paint, thanks to bitumen impregnation, does not crack on the surface of ondulin, but tends to fade in the sun. This happens especially quickly if the home owner decides to save on cost. construction work and purchased cheap roofing material. To prevent the painted surface of the roof from swelling, it must be absolutely dry and clean.Roof paintingproduced in spring or autumn, when solar activity subsides, and during mild bitumen roofing you can move freely. If it is necessary to apply a primer or putty on the surface of ondulin, it should be allowed to dry for several days.

Experts recommend using paint on the surface for acrylic base. If the roof surface is covered with real French ondulin, then for its treatment you should purchase a branded acrylic paint or analogues recommended by the manufacturer.

Ondulin roof painting

RoofingRoofondulinaafter preparatory work and applying patches, as well as good drying, can be painted.Roof paintingIt is made in two layers, and if the process is performed for the first time, then the ondulin roof must be primed. The viscosity of the first layer should be lower than the finishing one. Such shading is necessary for better wetting of the surface and penetration of paint into all irregularities. Painting the patches is done without sharp pressure on the brush, so as not to disturb the integrity of the edges of the restored roof area.

Processpainting ondulinIt is recommended to start with the ridge and slopes, gradually going down. During the painting process, a hard bristle brush should be rotated periodically to ensure even abrasion. To form an even and high-quality layer of paint, the brush is held in the hand in such a way that the pile is perpendicular to the roof surface. It should be remembered that after painting, each layer must dry thoroughly. The first layer dries for at least 5-7 days, the second - about 10 days.

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, the color of Ondupane is determined by pigmented mineral inclusions that are not subject to decay under the influence of ultraviolet radiation from 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.

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 sheets of roofing material of this type becomes brighter and more resistant to ultraviolet rays, so Euro slate 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 roofing material, in the manufacture of which bitumen impregnation was used, then 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.
