Abstract

The present invention relates to a method for spraying particulate solids onto a substrate, comprising the steps of:

coating the substrate with a wet and/or adhesive synthetic resin layer,building up a gas pressure in a line,generating a pressure differential in the line,swirling and carrying along particulate solids in the line,ejecting swirled, particulate solids from the line onto the surface of the wet and/or adhesive synthetic resin layer of the substrate. The invention also relates to a substrate, in particular a wood-based panel or decorative paper, at least partially coated with a particulate solid, characterized in that the particulate solid is applied to the substrate with an accuracy of up to ±0.8 g/m2, preferably of up to ±0.5 g/m2, particularly preferably of up to ±0.3 g/m2, preferably of up to 0.1 g/m2.
