High Performance Polyurethane Water Based Top Coat Review 12/16/2010

5 years 7 weeks ago

By far the best finish for my projects that I have found in 50 years of woodworking. On kitchen table, this is the only product that stood up to the wear and normal use conditions.

Use of EF extender is a good idea in summer: higher heat/low humidity accelerate the drying too fast leaving brush stokes. With extender, and/or higher humidity, the finish levels out well.

High Performance Polyurethane Water Based Top Coat Review 02/06/2011

I used the High Performance Polyurethane for the first time on an entertainment center I made. I was very happy with the application process. It seems to be marginally thicker than the other popular water based poly which I have used in the past. I had no problems with dripping, sagging on vertical surfaces and small bubbles (foaming) forming on edges and at joints which I have had with the other poly. More expensive but well worth it.

I used the High Performance Poly on a recent project and was absolutely thrilled with it's application. I have used the other popular water based product in the past with trouble with sagging on vertical surfaces and small bubbles on edges and where surfaces come together. I had none of those problems with High Performance Poly. It is well worth the higher price.
