ColorTone Waterbase Sanding Sealer Instructions

Directions for using ColorTone Waterbase Sanding Sealer.


ColorTone Waterbase Guitar Lacquers have been formulated to give a clear, hard, easy to apply and easy to repair alternative to current solvent finishes. The ColorTone waterbase product line includes stains, pigments, grain filler, sanding sealer, clear gloss topcoat and retarder. These materials can be used together exclusively, or used under and on top of many other products, such as shellac or lacquer.

Waterbase Sanding Sealer is a clear, hard, shrink-resistant acrylic polymer lacquer sealer. Successive sealer coats will bond best when applied within 48 hours of each other. When this time is exceeded, sanding with 320-grit paper is required to roughen the surface for adhesion of additional coats.


Mix well. Stir gently, do not shake. Allow air bubbles to settle before straining and pouring into spray equipment.

ColorTone waterbase products require a clean, dust-free, wax-free surface for optimum performance. New wood should be sanded to 220-grit, vacuumed and blown dust free. If the surface has been contaminated with oils or waxes, wipe down with an equal mix of denatured alcohol and water. If the surface has been modified, clean and test waterbase products compatibility before proceeding.


Waterbase finish doesn't look wet and glossy as you're spraying, unlike nitrocellulose. Be careful not to lay it on too thick, looking for that glossy wetness. Good lighting is very important. Spray light coats, carefully overlap your spray pattern by 1/3 - 1/2 for coverage with uniform thickness.

Optimum spraying condition is 70°F, and 45-60% relative humidity. Dry, oil and dirt-free air with proper ventilation is a must.

  • For gravity feed spray gun, 40-60 psi with a tip size of 1.3mm is recommended.
  • For siphon feed spray gun, tip size of 1.8mm is recommended.

Waterbase Retarder or water can be added to reduce viscosity. When hot/dry conditions cause the finish to dry too fast, thin with 5%-15% Waterbase Retarder.

Clean up

Clean spray equipment with warm, clean water immediately after each use. Do not leave lacquer in the spray gun for more than a few hours at a time. Remove dried finish with very hot water and alkaline cleaner, such as an all-purpose cleaner, degreaser or stripper). Store unused lacquer in a sealed container.

Keep out of the reach of children.

Keep from freezing.
