Floors for walking, or workshop, any urethane fortified or acrylic epoxy is fine. For my house this will be what I need.
Floors for driving, parking....!00% solids epoxy will perform/last the best. For a client This would be the route to take.
Before painting ANY floor do the plastic test. Tape down ( duct tape works ) a piece of plastic to the floor 2'x2', 3'x3' or so. Leave it overnight, check in the morning....any condensation, or dampness on the concrete...DONT PAINT IT!!! It will fail....definitely. Thanks! I'll do that (If I can find a clear spot that big ha ha).
Prep...mechanical etching is the best...you get a uniform surface to coat, either rent a floor grinder ( looks like a floor buffer but has diamond blades ) or have it shot blasted. Acid washing is ok, but typically you dont get a uniform profile, so some spots will have better bite than others. I'm used to acid wash, I use Muratic acid. Do you have a recommendation on the mix? Because I usually mix it pretty stong 16-20 Oz. per gallon.
Painting....The 100% solids has a very fast application time...usually 20min pot life or less. Mix the epoxy per manufacturer specs...and pour it on the floor in ribbons, squeege or use a 1/4" I was going to use 3/8 but 1/4 or less sounds better. nap roller to move it around ( it self levels so dont worry about lap marks ) Garage floors that have expansion joints are easier to do, just do 1 section at a time. My epoxy comes in 1 gal and 3 gal kits. I usually sell the 1 gal kits just because of the short pot life. Mix it 1 kit at a time, and 1 kit is typically enough to do 1 section of floor, expansion joint to expansion joint. 2 car garage = 4gal, 3 car = 6gal ( 1 coat ) may require 2 coats for an even sheen depending on floor porosity. So, I take it you don't recommend I use my Quikrete Kit? It's too small for my 2CG anyway.
