SURFACE PREPARATION AND APPLICATION PROCEDURE 

Bare Wood. The surface should be clean and dry, sandpapered and dusted off. Apply a first coat of TOPKAPI OPACA onto bare wood, highly diluted up to 50-70% (depending on wood absorption) in order to allow the varnish to sink into the wood substrate. As a clear primer alternative, one coat of POLIGLASS two-component varnish diluted 50-100% (depending on wood absorption) with Thinner 203 can be applied; care should be taken in order to maintain the grain of the wood open so to enable the application of subsequent coats of TOPKAPI OPACA. Overcoat then with 4-5 coats of TOPKAPI OPACA, allowing the required waiting time between coats.

Previously Varnished Wood.
- If the old paint is in poor conditions, loose or powdery, it should be mechanically removed. Clean the surface well and follow application directions as per bare wood.
- If the old paint is in good condition of adhesion and it only needs a topcoat because it is dull or dirty but with the underneath coatings still well fixed to the substrate (with no cracks or bubbles), clean,degrease and sandpaper with medium-fine abrasive paper and apply 2-3 coats of TOPKAPI OPACA, allowing the required waiting time between coats.

Note: In the summer season or when temperatures are higher than 20°C, it is recommended for brush application the use of flowing THINNER 109.
