Re: epoxie temperature
Posted by LeeG on May 25, 2005
think of it this way, the closer the shop temp is to 70degrees the easier it is to wet-out and squeegee the glass to a nice even flat layer. The more even the wet-out coat is the less likelyhood of sanding into wrippled glass. The thicker the epoxy is,,and under 50degree epoxy is thicker, the harder it is to squeegee out evenly. Colder temps use up a bit more epoxy, more epoxy that needs sanding off,not necessarily more epoxy where you want it because thick epoxy will drip six hours down the line when you didn't see it happening in the first hour. You have to put on more epoxy when it's thicker because it doesn't move around as easily. You don't have to keep the garage at a warm temp the whole time,, just getting it up to 60 and turning the heat off is much, much better than glassing it at 47 degrees and having a five degree rise in temps cause bubbles. Starting at a low temp. means that any variation will be to the upward direction,,rising temperatures cause bubbles. If you start at a high temperature then you've just put yourself in a good position for glassing AND potential out-gassing since the temps will be falling until it hits that 47 degrees. It's doable but it's not worth it.
