Wow, that DeVoe Tru Glaze 4508 looks to be indestructible !
I used quick rete brand and have had no chipping or scaling.
Just make sure the concrete is spotless.
I powerwashed mine, twice.
Then etched the concrete with acid.
The grit stuff on the floors sucks. Sucks for anything with casters, engine stands, lifts, chairs,etc.
Next time, I will definitely use the DeVoe product, thanks Migmaster.
