Sealer composition
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.
1. A method of finishing wood that has been previously finished, comprising:
locating an exposed section of wood not covered by the finish;
bleaching the exposed section of wood with an acidic bleach;
concurrently neutralizing any remaining acid on the exposed section of wood and sealing the exposed section of wood with a sealer composition by applying the sealer composition to the exposed section of wood, the sealer composition comprising polymer solids and an acid neutralizing agent, wherein sealing the exposed section of wood comprises sealing the exposed section of wood with the polymer solids and neutralizing any remaining acid on the exposed section of wood comprises neutralizing the acid with the acid neutralizing agent;
finishing the exposed section of wood; and
during sealing and finishing of the exposed section of wood, preventing premature precipitation of the polymer solids on the exposed section of wood via the neutralization of the acid with the acid neutralizing agent.
2. The method of claim 1 , wherein the sealer composition comprises a neutralizing agent, and wherein the neutralizing agent comprises sodium tetraborate.
3. The method of claim 1 , wherein the sealer composition comprises polymer solids made from at least one monomer type selected from the group consisting of: acrylate monomers, urethane monomers, and combinations thereof.
4. The method of claim 1 , wherein preventing premature precipitation of the polymer solids on the exposed section of wood comprises adjusting the pH of the exposed section of wood to a predetermined non-acidic pH.
5. The method of claim 4 , wherein adjusting the pH of the exposed section of wood to a predetermined non-acidic pH comprises adjusting the pH of the sealer composition to a desired pH associated with the predetermined non-acidic pH.
6. The method of claim 5 , wherein adjusting the pH of the sealer composition to the desired pH comprises adding a base to the sealer composition.
7. The method of claim 6 , wherein the desired pH of the sealer composition is equal to an acid association constant of the base, and wherein the base is added to the sealer composition until the pH of the sealer composition is equal to the acid association constant of the base.
8. The method of claim 5 , wherein adjusting the pH of the sealer composition to the desired pH comprises adding an acid to the sealer composition.
9. The method of claim 1 , further comprising selecting a first weight percent of polymer solids in the sealer composition and a second weight percent of acid neutralizing agent in the sealer composition to prevent premature precipitation of polymer solids on the exposed section of wood during sealing and finishing of the exposed section of wood.
