APPLICATION DIRECTIONS
DIRECTIONS FOR USE
New Wood Floors:
-
- Prepare floor according to NOFMA or NWFA specifications.
- Apply DuraSeal™ Masterline® Polyurethane using a lambswool applicator or natural bristle brush at a coverage rate of 500-600 square feet per gallon. Application of thicker coats extends dry time.
- Allow to dry fully for 8-10 hours, then screen the floor and tack floor with a cloth moistened with mineral spirits to remove dust.
- Apply at least two more coats in same manner as steps 2 & 3. Additional coats of polyurethane may be applied if desired. Be sure to allow each coat to fully dry and screen lightly between each coat.
Screen and Recoat:
- Clean floors with an abrasive pad moistened with mineral spirits to remove all grease, soap residue, oil, dirt, etc. Once dry, screen using a No. 100 grit screen. Do not apply over floors previously finished with shellac, lacquer, wax, or stains
containing stearates, wax or finishes in very poor condition in need of complete removal. - Follow step 2 under New Wood Floors. Tack floor with cloth moistened with mineral spirits to remove dust.
Old Wood Floors:
- Sand floor to bare wood according to NOFMA or NWFA approved methods. Make sure to remove all existing stain and finish.
- Tack floor with cloth dampened with mineral spirits to remove all dust.
- Follow steps 2 through 4 under New Wood Floors.
NOTE: Polyurethane will have a slight darkening effect when applied over light colored surfaces. Do not apply over floors previously finished with wax, shellac, lacquer or stains containing wax or stearates.
