Coating wooden components Perfect embellishment and permanent protection for wooden components

Do you need to coat non-dimensionally accurate, limited dimensionally accurate, or dimensionally accurate wooden components in exterior areas? Or wood and wood-based material in interior areas? Are you looking for a covering, glazing, or colorless wood coating? After the criteria have been selected, the product assistant guides you directly to the right product.

No other material is as versatile as wood - but it also has a number of peculiarities to be contended with: As a natural material, wood is extremely challenging. Wood has to be protected from the sun, moisture, and temperature fluctuations. As early as the planning phase, it is important to ensure that wooden components are protected from moisture penetration. Rain and condensation must drain off without obstruction. Because constructive faults cannot be rectified afterwards, even by the best coating system.

• Adequate eaves: The eaves should be dimensioned such that direct weathering is avoided to the greatest possible extent. Wood components should not be used in the splash water zone!
• Protection of end-grain faces: Cut surfaces across the grain (end grain face) are particularly susceptible to moisture absorption and have a high rate of swelling. The end grain face should therefore be protected from direct weathering to the greatest possible extent.
• Drip edges: These serve to drain off the water as quickly as possible.
• Rounded edges: For dimensionally accurate wooden components – e.g. windows – all edges must be rounded to achieve a good edge protection with an adequate layer thickness.
• Avoid contact with the ground!

Chemical wood protection should always be implemented selectively – i.e., only where required due to the type of wood used and the situation on site, and also only where its effect is actually needed: deep in the wood. The impregnation to be used must therefore have a good penetration properties.

Brillux Wood Preservative Primer 250 is ideal for deeply penetrating into the pores of the wood, thus protecting non-lbearing timbers without ground contact in exterior areas as well as windows and exterior doors against blue stain fungus. Its effectiveness was acknowledged in an EU-wide approval procedure for wood preservative.

Physical wood protection is used in addition to the constructive measures and chemical protection. In this context, suitable coatings are used, which, on the one hand, keep the impacts of weather away from the wood and, on the other hand, are used for surface design. Flexible protection against algae and fungi In addition to soiling, microorganisms such as algae and fungi are increasingly becoming a problem for exterior surfaces. The unique Protect protection concept from Brillux provides flexible and extensive protection in all color shades and for all substrates – including wood.

The selection of the correct wood coating is based on the criterion of dimensional stability. This defines how much a wood component changes or is permitted to change its dimensions due to swelling and shrinkage. We differentiate between non-dimensionally accurate, limited dimensionally accurate, and dimensionally accurate wooden components, which all require specific coating build-ups.

Dimensionally stable

Wood components are classed as dimensionally stable if their dimensions are only allowed to change to a very limited extent. Windows, exterior doors and window and door shutters that have been mortised and glued for dimensional stability are mentioned as examples in this context.

Limited dimensional stability

Wooden components with a limited range of allowed dimensional changes are considered to have limited dimensional stability. Examples include groove and tongue paneling, garden furniture, framework, roof soffits and ledges, as well as exterior doors, window and door shutters, if they are not already considered to be dimensionally stable.

Non-dimensionally stable

Components that are non-dimensionally stable are those whose volume changes are not limited, e.g. exterior wooden siding mounted with an open joint, open lap siding on a slatted frame, overlapping wooden paneling, shingles, palisades, wooden grating or fences.

and data sheet before use. Wood is an organic, renewable material. But continuous exposure to weather requires a special, long-lasting coating to care for it. Are you looking to achieve the best visual result when designing both interior and exterior areas, while still ensuring appropriate, all-round protection for wooden acades and other wood components?

Then don’t make any compromises. Our Surface Woodstain 620 and Matt glaze 618 are specially designed to protect wooden surfaces. For those who prefer a matter, more natural wood effect, then Matt glaze 618 is the right choice. Alternatively, our Surface Woodstain 620 ensures a great, silk gloss wood effect – and of course, both woodstains are aromatics-free.

The impact of shortwave UV radiation damages the most important components of wood: cellulose and lignin. The impact of the radiation on lignin is particularly drastic. Lignin is stored as a paste-like substance in the cell wall and ensures the stability and hardness of the wood. The high-energy UV radiation gradually breaks down the lignin.

In exterior areas: Permanent Protection Woodstain 580

Wood is a demanding building material, which is subjected to the highest levels of stress in exterior areas and therefore requires special protection. This is not just about the appearance, but above all permanently guaranteeing the function of the components. It is therefore essential to choose the correct coating. The material must

• withstand changing weather conditions
• guarantee long-term protection from UV radiation
• be resistant to embrittlement
• have optimal substrate adhesion

With the Permanent Protection Woodstain 580, Brillux has developed a wood coating that fulfills exactly these requirements – and even more than that. In addition to outstanding protection, it also provides ease of application.
