Preparation:
Oil based stains must be completely dry before using a waterbased top coat. Wait a minimum of 48 hours before applying this product.
On raw wood, sand with the grain using #120 and finishing with #220 grit paper. On stained wood, sanding with #320 or finer paper or buffing with a buffing pad is optional. Do not sand through the stain.
Application:
- Stir Well prior to use.
- Using a foam brush or paint brush, apply liberally using smooth, even strokes going with the grain. Use enough material to provide a wet film. Do not over brush. Apply and move on.
- Sand between coats using #320-#400 grit paper or extra fine to super fine sanding pads. Remove dust before recoating.
Tools:
High Performance Poly can be applied via brush or spray.
- Brush: Use a quality foam brush or paint pad applicator.
- Spray gun: Exterior 450 can be applied with Compressed air, HVLP, Air-Assisted Airless & Airless guns. Check your equipment supplier for proper tip sizes.
Allow 1 –2 hours between coats before sanding (temperature / humidity dependent). Sand between coats with 220 micron or # 320 grit paper or finer. 3 - 5 coats recommended.
Drying time: Dry time is normally 2-4 hours under ideal conditions (70°F or 21°C, 70% humidity). Cooler temperatures and higher humidity will prolong drying time up to 8-10 hours.
Number of coats: A minimum of 3 coats is recommended. Additional coats may be applied to increase durability and depth
