This product is designed to fill the pores of open grain woods and helps to achieve a smooth finish. Woodgrain Filler is natural in color but is best used when intermixed with a solvent-based wood stain to obtain desired colors.
Where to Use
Woodgrain Filler is recommended for interior use on open pore wood species or woods with large imperfections. Especially recommended for use on hardwoods, such as oak, ash, and mahogany.
Surface Preparation
All surfaces must be clean, dry, and free from dirt, wax, or grease.
Bare Wood: If persistent wax exists, remove with fine steel wool saturated with paint thinner or alcohol. Surface must be lightly sanded and sanding dust must be removed.
Previously Finished Surfaces: Strip the surface completely down to bare wood with paint or varnish remover, making sure all previous finishes are removed. Surface must be sanded smooth and sanding dust must be removed.
Application
- Stir thoroughly before and during application.
- Thin Woodgrain Filler with ratio of two parts filler to one part wood stain. Mix thoroughly.
- Apply using a clean, soft brush; plastic scraper; or cloth. Apply the filler in the direction of the grain to ensure filler packs into the grain.
- Let filler set for 5 to 15 minutes. Remove excess using a clean burlap type rag, working across the grain. To eliminate any streaks, wipe lightly once more, this time with the grain.
- Woodgrain Filler will thoroughly dry in four hours.
- Sand smooth and remove dust.
- Surface is now ready for finishing coats. If the stain color is lighter than desired, add an additional coat of stain.
Helpful Hints
Filler used in its natural form may prevent your project from accepting stain due to differences in porosity of the natural wood and Woodgrain Filler. It will also prevent the filler from drying in a timely fashion. We highly recommend thinning this product with wood stain. Test this product on a sample piece before starting your project. Old Masters Woodgrain Filler dries hard and may at times have some very minor shrinkage. If no staining is desired, be sure to let the filled surface dry for four hours before applying varnish or clear finishes. Allow 16 hours before applying a lacquer.
Thinning
Old Masters Woodgrain Filler must be thinned with a ratio of 2 parts filler to 1 part wood stain. Mix thoroughly. If a natural color is desired, mix Woodgrain Filler with Old Masters natural colored stain. We do NOT recommend the use of mineral spirits or paint thinner in place of stain.
Coverage
Approximately 500 square feet per gallon depending on the type and porosity of wood.
Drying Time
Woodgrain Filler will set up in 5 to 15 minutes and will be thoroughly dry in approximately 4 hours. Ensure surface is completely dry before applying varnish or Old Masters® Clear Finishes. Wait 16 hours before top coating with a lacquer. Drying time will be affected by temperature and humidity.
Cleanup
Using a cleaning solvent, such as paint thinner or mineral spirits, is recommended for cleanup. The use of paint thinners or mineral spirits may violate VOC compliancy in your area. Check with your local government agencies to ensure proper compliancy.
