Painting My Basement

542 102 September 2, 2020 at 02:06 PM
I moved into my house 15 years ago. it had an unfinished basement with a poured cement foundation. The previous owner put sealant on the walls. now the sealant is starting to Chip away a bit. I want to paint the walls, so should I add another coat of sealant and then paint over it? or should I do the tedious job of stripping the previous sealant and starting over? thanks

Paint is only as good as what it is attached to.

So if you paint over all that chipping paint, you'll eventually end up with Chipped paint on the floor, but it will have fresh paint on 1 side when it lands on the floor.

any sealant that is loose you should remove, if it is still sticking well you are fine. But you need to look at why it is coming off in spaces was it poor application or prep, or is is leaking weeping there? Check your outside to see if water is coming in from something outside in those spots.

We had those in the house I grew up in! Yes, bunny, the 1970s, not 1870s Smilie

Having a basement finished right now...fully framed it instead of a drop ceiling, which I hate. Fortunately, I work for a commercial drywall construction company, so my walls are going to be NICE.

Do it right or not at all. If you paint over chips, you'll just have painted sealer chips on the floor.

Well if it was 1870's they'd be worth something as they would have been made from actual wood. bulb

So the crew is gonna come out and "Spackle" your walls Roll

It would be in your best interest to completely strip the wall with either a sandblaster or a wire brush. You'll want to start fresh so that you can visually inspect your basement walls for cracks or efflorescence. Once you've inspected your walls and took care of any issues it's now safe to seal your walls. You could look into Drylok White Extreme Waterproofer or something along those lines. When that is all done I would say it's safe to paint your walls. Slickdeals is sort of like Wikipedia laugh out loud meaning that it's merely a starting point. I'm not a professional by any means, but I hope this guides you in the right direction. Just remember, what made it peel in the first place will more than likely make it peel again without proper treatment. Good luck.

Thanks, I was hoping this was not what I needed to do, but I am convinced that it's the best long term...
