Hi all. First time poster, long time lurker. Ive spent more than a few weeks reading (and rereading) just about every thread in this sub. Lots of info, even more questions.
So Ive been studying the similarities and differences between the commonly recommended DIY coatings - the polys offered by ArmorPoxy, Legacy, and Garageflooring LLC (AWF), and the Rust Bullet Duragrade and Hellfire products.
So my question is: is there any benefit to building up more thickness than what is a typical application for these products?. The polys each seem to put down similar mils per coat, all else being equal. At what point does the cost of the product outweigh the benefit of additional coatings, or put another way, why is 2 or 3 coatings the recommended standard?
Nohr-S calls for a coat of primer, a coat of base, and a top coat.
SPGX is a recommended two coat application (no primer?).
AWF is a two or three coat application.
Hellfire recommends 3 coats with optional clean coat. Hellfire coats less thick than the polys above.
Rust Bullet Duragrade recommends between 2-3 coats as well, optional clear coat.
The Hellfire and RB being less expensive, arguably less aesthetically pleasing and certainly less thick, but would these perform better than the polys if you were to add thickness until you were at the same cost point as the polys above? #Flooring
