let me know the name of the paint suppliers near your home and I'll tell you product and prep...
I always use a 2 component aliphatic urethane or a solvent based epoxy
it withstands full water submersion and every chemical you can throw at it....
slippery as hell when wet but I would still aviod throwing silica sand in it for an aggregate...reason being the sand can be crushed leaving a possible void in the membrane surface...
theres a product that is called "shark tooth" that is titanuim oxide in make up that can be used as an aggregate but i would avoid using any at all, makes it easier to maintain...i.e.clean up
ballpark for materials would be about 60.00 per 1 gallon kit, average 2 car garage would take 3 gallons for a good dry film thickness plus you would need a charcoal cartraige (sp.) breathing resperator for about 25.00 so you don't die while it's venting off or drying..you need about 20.00 for a gallon of proper solvent for clean up or whatever... and last but not least, about 10.00 for a throw away brush and rollers
