I'm in the process of prepping my garage for epoxy coating which I will be doing the weekend after next. So far, I've ground the edges with an angle grinder and diamond blade. I rented a floor polisher with a diamond blade and sanded the floor last night.
Unfortunately, the floor polisher was not abrasive enough to sand down the 1/2" lip in the center so I will be renting the "big" machine this weekend to finish. I will follow everything with acid wash and many rinses.
The product states that I need 48 hours drying time before applying epoxy. And, it should be applied between 60 and 85 degrees. At this time, the low temps at night is around 50 degrees and so I was going to use a propane heater to keep the garage warm overnight. Although, my garage is insulated and seems to be warmer than the house in the morning.
A friend of mine (an engineer) tells me I have to use an electric heater and not propane because propane will increase the humidity.....Does that sound reasonable? I figure I will have at least 3 fans running and the heater and I can't imagine the humidity increasing so much as to ruin my project. He started quoting the elemental table so he may know what he's talking about but I don't think I will be affected. Out normal humidity this time of year is around 35%
My one worry is that my garage has a wood sill plate (not concrete) and so I want to make sure it is completely dry before my epoxy job (even though it's not getting painted). And, I will have fans running for about a week before painting.
