Concrete garage floor sealers / coatings

scottIN

Not to tout another forum, but head over to Garage Journal. There are hundreds of threads over there about floor coatings. There's a lot that goes into doing it right. A relative of mine did his with the crap you buy at big box retailers and it looked great...for about 2 weeks. Then the hot-tire pick up started and it was all over.

I didn't dig very deep but, if nothing else, it looks like a real good place to start.

That's the perfect web site for this thread's topic.

I'm 90% sure I'm going to use Rust Bullet (RB) for concrete. Because the vast majority of our garage's floor is in very good condition, I figure that I can coat the relatively small part of the floor under our wintertime Great Salt Lake with just one amazingly-expensive quart of RB.

I hesitate only because RB has only been around about 3 years, so long-term user experience is non-existent. But in this case our garage will probably act as an early-adopter RB torture-test for the snow-belt crowd.

If anyone reading this has used RB, I'd love to hear what you think of it so far.

The job is done.

I first lightly ground all of the concrete surface to be coated. After removing all dust, I coated with Rust Bullet "High Performance Industrial Grade Protective Coating", which the local distributor claimed was the same formulation as the coating for concrete, but with another nameplate.

With 1 quart I was able to brush on 4 very heavy coats and, BTW, this stuff stinks! After drying for 3 days, there is no peeling whatsoever and, to my touch, I'd think only one heavy coat had been applied. The concrete must really soak up this stuff like a sponge.

It is amazingly difficult to discern details in the paint and the concrete underneath, even by eye, so it's even more difficult to take photos that show any detail. The rougher sand-mix that I used to fill in the spalling appears and feels rougher to the touch.

Next spring I'll report back how it performed under the sandy, salty lake of winter. If the stuff performs well, I may expand the coated area or even coat the whole floor, but the latter would require renting a large grinder and removing everything from the garage for several days. In short, it would be a real royal PIA to do.
