Mixing and Application Guidelines

Stir and homogenise the product before use. Some of the contents settle during storage and must be redispersed. Allow some minutes to release air bubbles. Stirring should be done at low speed, avoiding mechanical means to prevent bubbles. If needed, the product may be thinned with up to 10% of Acrypol solvent, as a viscosity adjustment. Never use universal or unknown solvents (e.g. white spirit or alcohols) Apply by roller, brush, spreader or airless equipment. It is useful to apply in 2 differently coloured coats, at 1,5-2 kg/m2 each It is strongly recommended to use entirely the product of the container. Non used product even kept in a closed container, may develop a thick cured skin on the surface.
