Application conditions Temperature should be between 60F. and 80F. during application. Air humidity below 70%. Avoid varnishing in too much wind or sun. A rapid loss of solvents will occur under these conditions and will decrease the flowing ability. Add thinner up to the specified percentage to compensate for the faster release of solvents. Any existing finish must be intact, degreased and sanded.

on wood above the waterline

Surface Preparation:
Bare wood must be clean, dry and free of grease etc. Degrease with Epifanes Spray Thinner For Paint & Varnish or denatured alcohol. Wiping down with mineral or white spirits, may leave an oily residue. Do not use water. Sand the bare wood to a fresh surface with 60 - 80 grit dry abrasive paper with the grain of the wood. A block may be used to assist in fairing the surface. Finish sand with 100 - 120 grit dry abrasive paper. If desired, stain the wood at this time with a good quality water based stain. Do not color the varnish itself as this will create a muddy appearance. Brush application with a good quality, clean, natural bristle brush will give good results.

Remarks If recoated within 48 hours, sanding is not required.

If existing coats of varnish are intact, one or more coats may be applied on a well cleaned, degreased and lightly sanded surface. Alternatively, the last two coats of Epifanes Polyurethane Clear Gloss Varnish may be replaced with two coats of Epifanes Clear Gloss Varnish. Allow 24 hours between coats and sand with 320-400 grit wet or dry abrasive paper. The one-component finish may be preferred if a more elastic topcoat is desired or required. The one-component finish also provides easier maintenance.
