New wood

The wood shows possible traces of resin, fat residue and sawing errors. In this case the horizontal surfaces (e. g. for decking) have to be high-pressure washed. Sawing errors can be sanded.

Freshly sawed wood

With freshly sawed wood a certain amount of time is required for drying before fitting. With boiler pressure impregnated wood the residual moisture is to be checked before coating.

For storage, distance beams are to be arranged between each stack of wood in order to ensure unobstructed air circulation between the planks. In moist surroundings the wood is to be covered. Eliminate or redress possible traces of resin, fat residue and sawing errors.

Pre-treated wood

Before every pre-treatment such as sanding, bleaching with TSP (sodium triphosphate), oxalic acid treatment, etc. please contact the supplier of the pre-treated wood for information regarding the compatibility of the protective system, as well as for health and environmental protection tips.

That’s how easy it is to coat with CETOL® WF 771:

Correct application:

• CETOL® WF 771 should be applied at a surface temperature range of 15° to 25° Celsius.
• Wood moisture of between 12 and 15 per cent is ideal for application of the coating.
• In the case of heavily weathered wood the wood should be sanded before the first coating.
• Evenly apply the CETOL® WF 771 stain.
• The entire quantity of paint applied must be absorbed by the substrate.
• The application of the paint should always be in the direction of the wood grain.
• Let the surface thoroughly dry after the base and mid coat.

Please avoid:

• direct sunlight when applying CETOL® WF 771
• dew formation or moist climate
• humidity of the wood above 18 per cent
• do not overdose; prevent the formation of puddles!
