Info & Guides


BARE WOOD: Sand with 80 grade (grit) paper. Wipe with Brushing Liquid 333. Apply sealer coat of varnish reduced 10% with Brushing Liquid 333.

PLYWOOD: Apply Inter-Prime Wood Sealer Clear 1026.

PREVIOUSLY VARNISHED WOOD: In Good Condition Sand surface with 120-150 grade (grit) paper and remove all dust. In Poor Condition If varnish is badly checked or peeling, remove finish to bare wood with Interstrip Semi-Paste 299E. Follow directions for varnishing bare wood.

Method Pour the amount you expect to use in a separate container. Strain it through a paint strainer to ensure there is no contamination. Apply at least 5-6 coats on bare wood and a minimum of 3 coats on previously varnished surfaces until a satisfactory finish is obtained. Sand between coats using 220-320 grade (grit) paper. Remove sanding residue with a rag dampened with Brushing Liquid 333.


Mixing Stir gently. Do not shake.

Thinner Brush - Brushing Liquid 333. Spray - Special Thinner 216.

Cleaner Bare Wood - Brushing Liquid 333.

Ventilation and Humidity Control It is best to paint on warm, dry mornings. Cold weather retards the drying and humidity can spoil the gloss.

Airless Spray Pressure: 170 bar/2500 psi. Tip Size: 0.33-0.41 mm/13-16 thou.

Conventional Spray Pressure Pot: Pressure: 3.44-4.47 bar/50-65 psi (gun pressure); 8-10 psi (pot pressure). Tip Size: 0.89-1.4 mm/35-50 thou. Siphon Cup: Pressure: 3.44-4.47 bar/50-65 psi - gun pressure. Tip Size: 1.5-1.8 mm/60-70 thou.

Brush Always use a clean brush that is kept specifically for varnishing. Clean brushes before use.

Roller If rolling, use a thin nap roller and "tip-off" with a clean natural bristle brush.

Other Spray pressures listed are recommendations only. The applicator may use any settings which yield the best results for the individual spraying technique and current weather conditions. To enhance appearance of the bare wood and fill porous open grain, apply Interstain according to label directions and allow to dry overnight.

Some Important Points Never leave bare wood exposed for long periods of time as it will absorb moisture. Avoid using Original straight from the can as this will cause it to age prematurely and may introduce contamination to the can. Failure to follow proper dry times carefully will cause improper drying, wrinkling and loss of adhesion. Avoid painting in direct sunlight. Product temperature should be minimum 10 C/50 F and maximum 29 C/85 F. Ambient temperature should be minimum 10 C/50 F and maximum 35 C/95 F. Substrate temperature should be minimum 10 C/50 F and maximum 29 C/85 F.

Compatibility/Substrates Apply to clean, dry, properly prepared surfaces only. Original can be applied over any varnish as long as it is adhered well and has been cleaned and sanded. Do not apply two part varnishes over Original.

Interlux Superspar Varnish
By Charlie from Tucson AZ

The over all flow and setting qualities are just not consistant that I experieced with not only other varnish but products in the Interlux line. I still feel that the best they have it the 2 part Perfection Varnish, however for my mast I wanted a standard varnish because of the ware factor.

Bottom Line No, I would not recommend to a friend
