Use after a sealer washcoat or sanding sealer to fill open pores and impart contrasting or matching color to the grain. (If used without sealing the wood first the color in the filler will color the wood background resulting in a muddy look ) Often used in combination with an NGR Dye Stain to achieve an ultra smooth finish. Grain filling must for high grade rubbed "Piano" finishes on open pore woods.

Reduce with mineral spirit or naphtha two parts filler to three parts mineral spirit or naphtha for walnut, mahogany, pecan, etc.
Apply over entire surface with a brush.
Use a Squeege to work the filler into the grain.
Allow to flash off (approximately 5 - 15 minutes). Remove excess by rubbing the surface with tightly folded burlap. Allow to dry four to 24 hours before applying sanding sealer.
