Cure time: Light use (7-10 days), Regular use (21 days) under ideal conditions (70 degrees and 70% humidity). Good ventilation, air movement and higher temperatures will accelerate dry time. Cooler temperatures will slow cure time. Cure time is the amount of time needed for the finish on a piece to reach maximum hardness and be ready for normal use. This is different than "dry time." This is different than "dry time." During the curing stage, treat your project with special care. Avoid placing heavy objects on it. Always avoid the use furniture polishes, dusting sprays or oil soaps as they may contaminate the finish for future recoating. Use a water dampened cloth for regular cleaning.
Water Spills and Daily Use: Clean water spills up as they occur during regular use and protect from heat. Although General Finishes products are water resistant, they are not impervious to water. Surfaces will not be damaged by spilled water so long as it is cleaned up promptly. We recommend using coasters to protect your wood from standing water and pot holders to protect from heat.
Cleaning your finish: Clean with a water-damp rag. Do not clean until the finish has cured completely (21 days). If your surface requires deep cleaning due to grease or grime, add a speck of detergent or a bit of vinegar.

High Performance Polyurethane Water Based Top Coat Review 12/16/2010
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.
High Performance Polyurethane Water Based Top Coat Review 02/11/2011
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.
