Garage floor coating recommendations

I had the concrete polished to a glaze when they poured my shop. Doesn't need a top coat if done right during construction.

We did a really nice coating on ours. If I knew how to post a pic on here I would. Pm me for an email address and I’ll send you a pic

A lot depends on if you use a vapor barrier under the concrete and how long it has been allowed to cure/dry. Coat it too soon and you will have issues. It takes at least 30 days for the concrete to cure and if no vapor barrier is used, there may still be some moisture coming up through the slab. We used to tape a piece of plastic visqueen about 3' square over the slab in a few locations and let it sit for a day or so to check to see if any moisture is still present. If the slab is completely dry than the Armorpoxy coating should work fine.

In my attached garage 28X20 I used Rustoleum 2 part Epoxy. It lasts about 10 years before it needs to be recoated. Once dry any epoxy is rock hard and will hold up under the weight of your MH. I needed 2 color kits (4 gal) and 2 clear kits (2gal).

My 68 year old garage floor was polished at construction time. Still looks nice and is easy to clean.

Agreed on the vapor barrier. If you don't have one don't bother coating it, it won't stay down anyway.

Side note, part of my real job was selling concrete coatings.

I've never seen a painted concrete highway or bridge. They hold up pretty well with all the heavy traffic on them. Build them right and they do not need any cosmetics to make them serviceable or look good.

My friends and I use Epoxy Coat. BEST STUFF IN THE WORLD. Even Brake fluid will not harm it. Takes 3 to 5 days to get it. Doug

No, but it looks so much better and is easy to clean when it’s done. It just gives it a much more “appealing look”.

Although not a garage, I am contracting a slab pour now for a house addition. My contractor said if I were planning to later add a coating or tile the floor, that it is important that they do not use a "Cure and Seal" product during the slab install. These products provide a barrier to help with the hydration but hinder adhesion of other products later. I plan to use the old method of lightly spraying water on the slab and covering with plastic until it has fully cured.
