How to Apply Nano Shield Prefin Additive

Surface Preparation

For best results, use at temperatures above 60°F (16°C) and 80°F (27°C). To ensure proper adhesion, surfaces must be clean, dry, free from old finish, wax, grease and dust. For best results, follow NWFA Approved Sanding procedures. Remove all sanding dust with a vacuum and wipe clean with a lint-free cloth lightly dampened with water. Allow to dry thoroughly.


Pour contents (8 oz.) of Nano Shield Hardener into one gallon of Nano Shield Rapid Cure or Nano Shield Advanced Floor Finish and stir thoroughly for 5 minutes, being careful to avoid foaming. Allow the activated finish to sit for 5 minutes before applying. After 5 minutes, follow the Nano Shield Rapid Cure or Nano Shield Advanced Floor Finish labels for application instructions. If the project needs less than 1 gallon, mix using a 1:12 ratio by weight. If a partial container is used, immediately close the bottle. DO NOT alter the prescribed ratio of Hardener to finish. A sample test area on the floor is always recommended.
