You don't want to put a water based product, especially an acrylic product over an epoxy floor. As far as this product, I don't know it. I do know based acrylic sealers and there's no magic pill out there that makes one hold up in a garage floor setting. Their claim to fame is the 35% solids. Elite Crete's WCS water based acrylic sealer is 37% solids. I wouldn't put our sealer in a garage as a long term coating. Any acrylic based sealer just doesn't have the strength to hold up as comparable to a good epoxy. Elite Crete's 53% solids solvent based acrylic with MMA is about the only thing I would think of using on a garage slab but being a solvent based material, I never suggest it used inside.
Acrylics are breathable, meaning moisture can go through it. Water based products will whiten out until the moisture passes. Often it will cause lifting of the sealer in wet environments on a smooth surface. More isn't better with these products. They are meant for only thin applications. gene
