We live in an old farm house (about 1915's) that is made out of rock faced block. It has not been painted for many, many years. The old paint in peeling off (we don't know if it's oil or latex). We want to sandblast it, but that will take out the mortar, we have been told. I've heard of corncob sandblasting, but was also told that will do the same. What can I use to remove the paint without having to remortar the entire house. I am a painter so I don't need any tips on that aspect of it. Thanks

Why don't you pressure wash the rock foundation and see where you stand ?

"...measure once.....cut twice....throw that one away and cut a new one...."

We have tried that to no avail. While it takes off the loose particals the rest won't budge. The problem is that we are afraid that it is oil based paint and therefor it needs to come off because, as you know, it won't allow the block to breathe. Since I can't tell whether it's oil or not maybe I should bring a chunk to Hirshfields and see what they think it is. Thanks though!

Just to clarify things, it's not rock, it's block. Also, it's the entire two story house, not just the foundation. This paint has been on there anywhere from 21 to 50 years and it's thick.

I have seen a painter use Peel-A-Way to remove paint on a garage block wall.

There are also many types of "sand" blasting that use media other than sand. Walnut shells, glass beads, even frozen CO2 pellets. They all have different characteristics.

And I suspect that they have different nozzles so tha tthey can concentrate the effort on the face of the blocks on reduce the work on the joints.

I would think that in a case like this you don't need absolute removal of the old, just enough to all moisture to go through.

Chemical strippers are another alternative but can get costly. There are strippers made for this purpose that you brush on, apply a cloth or fiberglass matting over, let set, then peel off.

Other types can be applied and power washed off.

But keep in mind it can be costly and may take several attempts to get it all off.
