Color flakes are U.V. stable and will not yellow (amber). If you opt for a full broadcast / full flake coverage, then you can do the epoxy base coat for optimal adhesion and build thickness. If you opt for a partial flake coverage, you are better off with the polyaspartic base color coat to avoid any chance of yellowing some years after. The polyaspartic clear coat will not prevent any epoxy exposed to sunlight from eventually acquiring a yellow tint. With quality epoxy, if the garage door remains closed most of the time or the garage faces somewhat north, it will take several years before the epoxy begins the process, if at all.

I believe it is full broadcast but I will double check. What are your thoughts with full coverage?

If it was partial coverage your answer changes I assume? 🙂

Hello Ray. The big question regards color flake coverage. This can make a difference in your choice. Are you opting for a partial flake coverage or a full broadcast of color flakes that completely covers the base coat?

I’m looking to have my concrete garage floor coated by a professional. I’ve got a number of quotes all pretty similar in price, prep & features. The difference being 2-3 companies mention they will use Epoxy base coat, flakes & polyaspartic top coat.

The other 2-3 companies mention they will do a polyaspartic base coat & polyaspartic top coat?

Looks like there is pros/cons with both. Epoxy being thicker & better bond to concrete & polyaspartic being no yellowing + 1 day process vs two.

My main question is will the epoxy base coat turn yellow if using a polyaspartic top coat?

What method would you recommend going with? Thanks!

Hello Brian. Most acrylic sealers are U.V. stable and will not yellow. Tuf Top lists that as one of its features. We recommend staying with the same manufacturer and applying the Tuf Top 289 Clear over the color coat and flakes.
