Winner of Fine Woodworking's "Best Overall Choice Award," High Performance Topcoat was voted as the hardest, most durable consumer polyurethane topcoat. It is so versatile, it can be brushed or sprayed.

General Finishes High Performance Waterbased Top Coat is a unique hybrid of urethane and acrylic technology. It provides superior toughness, durability and water resistance necessary for high wear surfaces such as tables and cabinets. The Waterbased Top Coat has a UV protection in order to protect the stains, paints and wood underneath.

High Performance Waterbased Top Coat dries quickly, has a low odor, and is a non-flammable alternative to solvent based coatings. It is ideal for interior woodwork, furniture, and cabinets.

General Finishes High Performance Waterbased Top Coat can be applied on most waterbased or solvent based stains and paints.

Directions for Use

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 #150 or #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 pad applicator, 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: It is possible to spray this product by diluting it with approximately 10% water volume.

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

This topcoat is excellent. The sheen is consistent with only the slightest amount of yellowing. Lays out evenly with a foam brush and drys fairly quickly.

Great top coat

Magdalena Cybulska · Mar 8, 2021

Used this for the top coat of my stained top dresser. Applied two coats as recommended. Project came out looking great. Will be using again.

Used this on a few furniture projects. A painted piece and a stained piece. Easy to use and beautiful finish. I used the satin finish and it was perfect for my needs.
