painting basement floor

I am getting ready to paint the concrete floor in my basement. Part of it is plain concrete while some is covered in the old mastic from old asbestos tiling we had removed. The mastic has a coat of some kind of sealant on it. Any idea if this can be painted. If so, any suggestions for what kind of prep is needed and what kind of paint should be used?

Thanks

1. Remove the old mastic. It will look far worse painted than it does now.
2. Don't paint. Stain instead. A concrete stain will last a long, long time. Paint on concrete is an ongoing maintenance item. In a few years it'll start peeling off.

You'll want to remove the mastic
It's really the only way

If you really want to paint it use a latex enamel for floors, such as Ben Moore's Porch & Floor

The area that I want to paint is in the laundry/utility room. It does not have to be perfect, I just want to brighten it up a bit. Also the mastic is asbestos and I would rather not mess with it at all. So to clarify, would the paint over mastic just look bad or is there a bonding issue? The mastic area is smooth so I am thinking if I just put enough layers of floor paint it will look okay. Any thoughts? Thanks.

Could be both
Please keep in mind I can't "maybe" in a customer's home lol
But maybe it'll be OK and do what you want
I didn't realize the mastic was smooth, but don't know if the paint will stick to it
It might

Its hard to tell if paint will stick - no idea what it really is. Use a quality primer first.

Hi dfbeasley,
I just read your post and am very curious what you did and how things have worked out. I am thinking of painting over mastic, and have the same concerns and thoughts as you (would rather not mess with it given asbestos), and also have young children so don't want to use strong chemicals. Did you find a floor paint that was able to bond over the mastic? Did you use a primer first? Have you had any issues since? Thanks so much!

Welcome to the forums jlarintgon!

The OP hasn't been an active member in several years so I doubt you'll get a reply from him.
The advice still stands - it's best to remove all the mastic before you prime or paint.
