They can yellow very slightly which could be noticeable if used in a thick layer. –UV-curable adhesives: Most commercial acrylic is 100% UV stabilised.
Do you have to acid wash concrete before epoxy?

This simply means that the cured epoxy has to be lightly sanded before the next coat is applied: the first coat should have a matt, almost white, surface.
Should you sand between coats of epoxy?
Sanding will not only get out the imperfection but will also serve to provide some tooth between the first and second layers. It will look very scuffed in the short term but do not worry, once you pour the second coat over top, all of those sanding marks will disappear.

There are two main types of concrete sealers: film-forming sealers and penetrating sealers. Film-forming sealers include acrylics, epoxies, and urethanes that form a coating on the surface of the concrete. Film-forming sealers, especially acrylics, are more susceptible to wear and will need to be reapplied frequently.
Does vinegar etch concrete?
Etching – Vinegar’s ability to dissolve CaCO3 will dull your marble, travertine, concrete and terrazzo surfaces. It may “clean” the surface but it is also dissolving pits into the finish and effectively dulling it. This will affect marble, travertine, concrete and concrete terrazzo surfaces.
Can you put two coats of epoxy on garage?
