Interprime Wood Sealer

Inter-Prime Wood Sealer Clear is suitable for either interior or exterior use. It stops varnish from soaking into the wood and seals the grain, thereby enabling subsequent coats of varnish or paint to dry without "high" and "low" spots.

This sealer is particularly recommended for sealing plywood to resist cracking and checking.

Part No.

Preparation Surface Preparation is as for the Finish.

Method WOOD filled with Interstain: Apply 1-2 coats. This will seal the wood and filler and then the paint or varnish of choice can be applied as directed. PLYWOOD: It is important to saturate the porous white summer grain of the wood until it takes on a glossy appearance. At least 2 coats will be required to reach this condition. Once gloss is obtained, the wood should be sanded with 120 grade (grit) paper before applying finish coats of paint or varnish.

Hints Thinner Brush - Brushing Liquid 333. Spray - Special Thinner 216.
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: 170-204 bar/2500-3000 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.
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.

Some Important Points Never leave bare wood exposed for long periods of time as it will absorb moisture. Avoid painting in direct sunlight. Product temperature should be minimum 10C/50F and maximum 29C/85F. Ambient temperature should be minimum 10C/50F and maximum 35C/95F. Substrate temperature should be minimum 10C/50F and maximum 29C/85F.

Compatibility/Substrates Apply to clean, dry, properly prepared surfaces only. Inter-Prime Wood Sealer Clear is not a finish paint and must be overcoated with varnish or paint. Do not apply two part varnishes over Inter-Prime Wood Sealer Clear. Do not use with two part epoxies. Plywood must be sealed prior to painting. Failure to stabilize the white summer grain by saturating with the sealer will cause premature paint failure. If the soft, porous, white grain is not sealed, subsequent coats of paint will crack and check causing paint delamination.

Number of Coats 2-3 depending on porosity

Coverage (Theoretical) - 0 (ft/Gal) 200-400 (ft/Gal) depending on porosity
