Protect the inside garage I just painted ?

Where in the garage did you paint - the floor, the walls.....?

Are you looking for protection against scratching, or moisture seepage....?

Check in your local home improvement store. There are several different concrete paint sealers available.

Hello. Are you asking a question about the walls or the floor? If it is the floor you might want to consider a concrete sealer. Here’s a link for your review and consideration

I am assuming you are talking about painting your floor.

Where did you purchase your paint? Different brands probably offer different solutions for a sealer - so maybe even just check the website of the brand of paint you purchased to find your answer.

I totally agree with checking the bran of the paint you have used as it may vary.

If you painted your floor, you need to put a clear epoxy on it. If you used a kit, it should have come with a sealant.

Did you paint the walls or floor? There are sealers for concrete floors at your local paint or home improvement store. Garages take such abuse, it’d be endlessly frustrating to try to keep the walls pristine.

Hi! Use a sealer that is intended for painted concrete. If it is the floor, you might consider one of the new epoxy kits they have for garage floors. Good luck!

Hi Keith, I know this is an ad, but it looks like a good product, hope it helps you out,

RustOleum Never Wet

We painted our outdoor concrete patio with Benjamin Moore Floor and Patio paint several years ago. No top coat was recommended or necessary. It still looks amazing. https://www.exquisitelyunremarkable.com/2018/08/how-to-paint-concrete-patio-makeover.html

Drylok is the product I would use to seal it.

I just painted my garage floor light grey with concrete paint as well. I found that I did not need any kind of sealer on top. Just recently we filled our garage with furniture, moved it around on the paint and we had no damage or scratches. It held up really well.
