Garage Floor Paint

Don't paint your garage floor. Concrete needs to breathe and it will cause the paint bubble and chip, guaranteed. This was told to me by a guy that does concrete work for a living.

I'd like to paint my garage floor, too.

Not saying he's wrong but I've seen some amazing painted airplane hangars floors. Do they use something else?

In a garage use epoxy, it's the only thing that will hold up driving on, I've put many gallons of it on in my life

ETA.. look into h&c shield-crete, it's a great DIY kit that works great

Quik Crete makes a good epoxy. It's a 2 part system. You have to be sure to clean the floor very well and etch with acid. Then vacuum really well and let dry. Then one coat, dry overnight and second coat. You can put flakes in it to hide any cracks. But you need to broadcast fine mason sand in it as well or it can be slippery. If your product doesn't provide a Grit you can buy bags of play sand. Maybe a couple bags in a double garage.

If done right it will not peel, chip, fade or discolor. I have 14 years in my garage and if I hit it with a little soap and a deck brush every now and then and hose it looks like the day it went down.

Architects are always putting permanant epoxies and sealants on our slabs for automotive service bays.

Yeah, but it's probably not the same stuff they sell in the kits at Home Depot.

I ordered this from Exopy Superstore. This was one of the only places I found that you could pick your own colors of chips. I applied it in my shop about a year ago and it still looks great.

I used Rustoleum garage floor epoxy (light grey) and Quikrete garage floor epoxy (darker grey on border) in 2007 on a floor poured in 2004.
They are a 2 part mix.
Did a 2 bay shop with one coat of paint and it's fine.
BTW - I did not use the "sprinkles", just the paint.

I used the Rustoleum kit from Home Depot when I first moved into my house. Its almost 10 yrs old and has held up. No peeling or any problems. It was an old stained slab too. The key to all of it is the prep work.

In the shop I just built, I went with a clear sealer instead of the epoxy.
