Best way to remove paint from cinder block wall
I'm remodeling a room in my basement and I found the cinder block walls had been painted with the first coat being a mildew resistant finish, and then the second, outer coat was Dry-lok waterproofing, so they painted the two types on the walls in the wrong order. (I found this out thanks to someone on here explaining to me why the Dry-lok was peeling off in large chunks :thumbsup: )

I am using a grinder with a coarse knotted cup brush to remove both layers of paint and it works, but it's eating up the brushes quickly and it's taking foreeeevveeerrr to finish the job. Is there a faster way?

stadry 08-27-2013 09:10 PM,,, IF you can rent 1, good luck,,, otherwise, use a wire brush mounted on a 4" grinder,,, much faster than the knott'd stuff

don't forget a leather apron, gloves, & GOOD safety glasses + face shield :thumbsup:

I'll try the regular wire cup brush, and hopefully it's faster than the knotted. Thanks!

Three straight days of grinding. My arms are sore. Someone is out of shape. :yes:

Wanted to give a thanks - the wire brush was definitely faster than any other method. :thumbsup:

Also wanted to let others know, the expensive wire brushes are worth it. Unless you enjoy picking out dozens of tiny wires embedded in your skin. :no:
