Painting with 2-part polyurethane

Another comment about potential problems.

Be very attentive to temperatures and weather forecasts. According to the manufacturer it is OK to apply a bit below the 10 degree celsius (50 F) recommended (maybe 8 deg C) but the dewpoint is a very important factor. Stay at least 4 deg celsius above dewpoint. Biggest problem with lower temps is lessening of gloss and increased cure time.

Temperatures should remain at or above minimum temp for 8 hours after application. If you do all the work and then it rains you could have "fisheyes" (more likely on a horizontal surface) or other problems.
