Honestly, I don't know of any method to rid yourself of paint in the millions of nooks and crannies you'll find in cinder blocks....

I'd suggest heading to a knowledgeable paint store to find out what sort of primer might work instead...........

Drylock will cover old paint but is not warrentied for it. My wall was covered with what looked like silver spray paint. 25 coats of dry-lok later and its no longer leaking.

The only option is sandblasting...which is messy and expensive.

I just encountered the same problem. Ah-yes...lovely flaking sea foam green paint. Sandblasting was not an option for us. We used a high pressure power-washer (2500psi-4500psi) and wet/dry vac. This is NOT a fun job, but it had to be done. I'm now in the process of Dry-Loking.

Good Luck ;-)

Lightning Strip

I'm in the process of doing this as well. It seems my block walls were painted then drylock or something simlilar was added. I tried about 25 different strippers and could barely get anything done. I was searching for something better than drylock and came upon this site.

I can't fouch for their sealers or coatings and what-not (though I plan on trying the radon seal for block walls when i get the paint stripped), but the site recommended a product called lightning strip. It's a wood stripper, but man it is making short work of the block walls.

Spray it on...wait a bit, scrape off the topcoat (which involves very little elbow grease). To get in the nooks and crannies I'm spraying on a second coat and scrubbing it in with a wirebrush, letting it set, then wirebrushing again.

Water clean up...low fumes..I love the stuff.
