I like these cool floors but why have they not figured out a product a guy can sweep out the goobers of dirt and bolts and slop some paint all around and have it bite into the concrete and stay...
seems like to much work and dollars and a hail mary for it to stay if you do it in a shop that was really used as such before painting
they have it for rusty steel, slap some Hammerite on and it stays for years with no hassle or sighns of failure...
