SURFACE PREPARATION AND APPLICATION PROCEDURE 
New or restored bare Wood. 
- In order to obtain “closed-pore” smooth surface, apply two coats of POLIGLASS varnish diluted up to 50-100% of THINNER 203 (according to wood absorption). If the pores on the wood is coarse, a third coat of POLIGLASS, less diluted, may be required. Let dry for 12-16 hours, rub down with fine abrasive-paper and apply 2-3 coats of ACRIGLASS UV allowing 24 hours between coats.
- On the other hand, if a surface with “open-pore” is desired, apply a single coat of POLIGLASS thinned 50-100% with THINNER 203, (according wood absorption). Let dry for 12-16 hours, rub down with fine abrasive-paper and apply 2-3 coats of ACRIGLASS UV allowing 24 hours between coats

Previously Varnished Wood. 
Test a small patch of the coated surface to verify if ACRIGLASS UV  is compatible with the old varnish and to make sure that the old coating is still in good condition.
-If the old coating is in good condition and compatible, sandpaper and overcoat with 2-3 coats of ACRIGLASS UV allowing 24 hours between coats.
-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. Then follow the application directions as suggested for bare wood.
Note_The recommended number of  coats for each varnish  is only indicative; the number of coats effectively required mostly depends by wood absorption. For bare new wood we recommend  the application of at least 10 coats in total of Poliglass and Acriglass UV.  For the restoration of old varnishes brought back to bare wood, the application of at least 6-8 coats is recommended.
