i recently painted the concrete walls in my basement white. The paint is starting to chip off already due to?

Question

moisture in the wall. Would drylock paint solve this problem?

Answer 1

it would be advisable to seal the concrete with a commerical applicant like Kilz or a similar product. Drylock would work, but it really would not do as well as a sealant followed by a regular paint. Basement walls are prone to be extremely damp and cold (even if no moisture is visible to the eye.

Answer 2

It appears you painted the basement walls because you are interested in using it as liveable space. In order for any paint to properly adhere to basement walls, you need to take care of that moisture problem. All basements that are below grade (meaning there is dirt against the outside walls) will have some level of continuous moisture in that space. You need to consider attacking the root of the problem.

I would recommend you aquire a Dehumidifier and have it permanently installed in the basement living area. What I mean by permanent is that you have a drain attached to the back of the unit that drains into a sink, washer drain, or sump pump. That way you don't have to manually dump the water from the dehumidifier.

Once you have a dehumidifier installed and running for a few days, this should dry the space enough to consider paint. Unfortuneately you're going to need to remove that coat of paint you applied. As someone at the home center how to accomplish this the most economical speedy way. Once the old paint is removed, I would use DryLoc paint and roll/brush a thick layer on the walls. Allow it to dry a few days then apply any paint color to the walls.

Good Luck... Hope this helps. :)

Drylock might stick better to the wall. If you are going to apply paint to concrete, you should read the manufacturer's recommendations about how to apply. Many require the walls to be dry before applying the paint. A good test for dryness is to use duct tape and tape a square of plastic to the wall. Allow it to sit undisturbed for 2-3 days, then peel off and see if you can see a difference in the color of the concrete (darker shade indicates moisture) or see moisture on plastic.

Answer 4

I would recommend drylock paint, this should last a few years. I paintedn my basement about 9 years ago and it still looks pretty good after using drylock basement paint.

Answer 5

Try scraping off as much of the paint as possible. Use block filler as your 1st coat. Make sure you completely cover the wall. The block filler is supposed to fill in all the little hole in the concrete. It kind of seals it. The you can put your finish coat on. Try using a higher quality paint than last time.I work for a commercial paint company on Ft. Hood in Texas. We use block filler on plenty of concrete walls that are constantly exposed to moisture.

Answer 6

Yes, put the drylock on first than paint.

Answer 7

Yes. You need to dry the wall & then apply a sealer. Moisture will contine to work it's way through, unless you have a sealer in place to stop it. Look for a paint with sealer for such applications, or a seperate sealer. I would think the seperate sealer would do a better job

Answer 8

Wall is damp. Try to make sure the wall is completely dry before paint. Try turning up the heating to dry out the wall. Then apply multiple thin layers to seal the paint.

Answer 9

you should have put a coat of primer on first. This time try a concrete paint see if that helps

Answer 10

no you probably have cinder block walls, if so ask your local hardware dealer for sealer paint and be generous when you apply it,, two coats is enough usually , then re paint with primer ad your choice of paint
