Abstract
A composition for sealing exposed wood before finishing the wood, which composition includes polymer solids and an acid neutralizing agent. The acid neutralizing agent may be a weak base and/or a buffering agent. The polymer solids may include acrylate monomers, urethane monomers, and the like. Also disclosed is a method of sealing and neutralizing a wood surface before finishing the wood surface by applying the composition to the exposed wood surface.
Claims17
A sealer composition for sealing exposed wood before finishing the wood, the exposed wood being treated by a bleach leaving excess acid on the exposed wood, consisting of:
- a dissolved polymer composition consisting of polymer solids and a solvent, wherein the polymer solids comprise between about 11 weight percent and about 35 weight percent of the sealer composition;
- and
- between about one gram per liter and about 40 grams per liter of an acid neutralizing agent;
- wherein the relative proportions of the polymer solids, solvent, and acid neutralizing agent are such that the sealer composition seals the exposed wood and neutralizes the excess acid on the exposed wood when the sealer composition is applied to the exposed wood.
A sealer composition for sealing exposed wood before finishing the wood, the exposed wood being treated by a bleach leaving excess acid on the exposed wood, consisting of:
- polyurethane solids;
- an acid neutralizing agent;
- and
- a solvent;
- wherein the polyurethane solids are dissolved in said solvent and the relative proportions of the polyurethane solids, solvent, and acid neutralizing agent are such that the sealer composition seals the exposed wood and neutralizes the excess acid on the exposed wood when the sealer composition is applied to the exposed wood.
A sealer composition for sealing exposed wood before finishing the wood, the exposed wood being treated by a bleach leaving excess acid on the exposed wood, consisting of:
- polyurethane and acrylate solids;
- an acid neutralizing agent;
- and
- a solvent;
- wherein the polyurethane and acrylate solids are dissolved in said solvent and the relative proportions of the polyurethane and acrylate solids, solvent, and acid neutralizing agent are such that the sealer composition seals the exposed wood and neutralizes the excess acid on the exposed wood when the sealer composition is applied to the exposed wood.
