Considering this, is it OK to paint basement walls?

DO NOT PAINT YOUR WALLS, even with Drylok or waterproofing paint. Also, do not attach insulation directly to the foundation walls. It behaves as a moisture trap and can also hide structural problems and cracks in the foundation. Bottom line: basement walls need to breathe too.

Similarly, what is the best paint to use on concrete basement walls? Prime the Concrete For exterior foundations and walls, use exterior-grade block filler, such as Behr's Concrete and Masonry Bonding Primer, which also is good for interior concrete ($17.98 per gallon). Primer dries in two hours; wait at least eight hours, but no more than 30 days, to paint.

Secondly, should you paint cinder block basement walls?

You need to paint the block first with block-filler paint then your finish coat. However, if you regularly have moisture coming through the the basement wall the only way for it to dry is to the inside. By painting the wall you will trap the moisture behind the wall which will eventually cause the paint to fail.

Should I seal my basement walls?

Seal The Basement Walls Because concrete basement walls are porous, they sponge moisture from the earth outside. This moisture enters your basement in the form of water vapor. This moisture will then build up behind walls, leading to mold, mildew, and moisture issues.
