I installed epoxy primer as
I installed epoxy primer as a base coat and used polyaspartic for my top coat. Before I could even begin I used liquid only epoxy mortar. I had some small broken areas along with one substantial broken area that was about 1. 5" deep by 4 or 5" around. I already had paver sand and assumed it would work as good as play sand. It DOES NOT! Stick to play sand. Because of the sand grain being so large. I was unable to make each layer as thin as recommended but it still worked fine. However, It took a lot longer to cure. But once cured, it was strong. I did my 2 car garage by myself. I ran into some issues due to the roller frame I purchased from Lowe's. Stick with the one Armorpoxy sells. Lost a lot of working time and ended up using a small 8" roller for over half the last coat and it was already setting up so my floor is not super smooth. There are spike marks and thin areas due to the roller issues. I ran out of time. My floor before was impossible to sweep and get it clean. It had a really rough finish. Armorpoxy polyaspartic completely changed my floor and I can keep it clean for the first time ever. Glad I did this and wish I had done it a long time ago. Next summer I'll lightly sand it and lay down a new top coat with their roller frame.
