Sand stone foundation and basement wall
Our 1852 home has a sand stone foundation which form the walls of our basement. I have tucked and pointed the crevases between stones with concrete. Then scraped the white wash off the wall, most of which had fallen to the floor anyway. I asked around as to what to do about covering the wall. It was recommended that I mix a slurry of 1 part lime and 3 parts portland cement and using a spatula cover the wall. It kinda of worked, I got all the wall covered but now after six years it is peeling off and exposing the sandstones, which then allows the old mortar to shell off.
Anyone got any other ideas on how to cover these stones. Any products that would go on as easy as a latex paint but stick.
