SURFACE PREPARATION AND APPLICATION PROCEDURE

Bare Wood.
- In order to obtain “closed-pore” smooth surface, apply two coats of POLIGLASS varnish diluted up to 50-100% (according to wood absorption). If the pores on the wood is coarse, a third coat, less diluted, may be required. Let dry for 8-12 hours, rub down with fine abrasive-paper and apply 2-3 coats of  POLIMAT varnish allowing the recommended waiting time between coats.
- On the other hand, if a surface with “open-pore” is desired, apply a single coat of POLIGLASS thinned 50-100%, (according wood absorption). Let dry for 8-12 hours, rub down with fine abrasive-paper and apply 2-3 coats of  POLIMAT varnish allowing the recommended waiting time between coats.

Previously Varnished Wood. Sandpaper the old varnish thoroughly and remove dust. If the old paint system was made with two-component polyurethane varnish, just overcoat with 2-3 coats of POLIMAT varnish allowing 8-10 hours between coats. If the old paint system is unknown it is recommended to test the new varnish on a small area to check if POLIMAT  is compatible with the old varnish and to make sure that the old coating is still in sound condition and does not soften when overcoated; if there will be no inconvenient apply 2 coats of POLIMAT varnish. In the case of loose, powdery or non-compatible old varnish, it is recommended that the old varnish should be stripped completely down to bare wood with a paint-remover or by scraping and sandpapering. Once back to bare wood follow the recommended coating system as indicated above for new wood.
