General Painting & Sealing

[detroitreds]

I have efflorescence coming through parts of the garage concrete floor. I've prepped the floor by diamond grinding, then applied some grout cement (no sand), to fill shallow puddles so that water can drain to the middle of the floor (where there is a drain hole). The floor and grout are not the exact same color, so I was wondering if there was some sort of paint that I could apply, then seal. Because of the efflorescence, I would need to be careful that the paint under the sealant doesn't get affected.

If there was a self leveling paint, or a thicker paint to hide small dimple like holes, then the floor would look great.

I'm just not trusting epoxy in my situation.

Most paints, even thick epoxies will show through dimples. Part of the reason is that as the paint dries/cures it shrinks. If it is thicker in a dimple it will fill it when wet then shrink more than the surrounding when it cures.

Efflorescence is the result of water moving up and out of your slab. When the liquid water reaches the air it turns into a gas leaving mineral salts or efflorescence behind.

Therefore most coatings will quickly be popped off.

Clean and treat with a densifier . Go from there.
