Amateur, lurker, learner, sort of perfectionist here with some dumb questions that I can't find the answers to in the forum anywhere else.
I am laying down a 100% solids epoxy on top of a water-based low solids primer since my concrete seems to be soft and porous. I did not have the ability to grind, so I vigorously etched twice using a more concentrated ratio of water to muriatic acid, and now seem to have a profile of about 80 to 100 grit sandpaper. I flooded it a million times with water after neutralizing the acid, and then pressure washed. My garage is only for one car, but I have a very heavy electric SUV which already caused some hot tire marks and mild depressions in the concrete, I would say. I noticed this after washing the concrete because there was some slight pooling of water at the places where the tires sit.
I have plenty of 100% solids epoxy, actually two kits. I planned on broadcasting to full rejection on coat number two, followed by a UV resistant top coat, which I'm not sure that I need given that my garage has no windows. Almost everything I've learned about doing a floor came from this forum, so shout out to everyone who meaningfully contributes. But, I guess my question is how thick of a 100% solids epoxy coat can I lay after the primer? Actually, I'm not even sure how long to wait before laying down the primer given my aggressive cleaning and etching and flooding of the concrete. But after that, can I lay a second coat of 100% solid epoxy for my flakes after the first coat dries? If so, how long between coats? I read somewhere that too much product can be problematic with regard to curing. In all seriousness, what would you do to your floor if you want it to park a 6,400 lb SUV on it every evening? Intuitively, it seems like a really thick coat of epoxy would be a good idea, but it also seems like too much epoxy might cause unsightly indentions where the tires sit, even if there is no hot tire pickup. How bouncy is this stuff if laid too thick?
Your constructive comments are already much appreciated. Take care.
