I have a house ~100 yrs. old. Basement walls are stone, probably some type of granite, with mortar. Inside that, there appears to be crumbling plaster that continuously drops dust and small pebbles onto the floor. How can I stop this? Is there a sealer I can use? Do I need to strip the whole thing and if so, what do I put back up over the stones? Thanks

Sounds like you may have an efflorescence or mold problem, which is pretty typical in these old foundation walls. What I am told by my contractor is you need to remove all the loose, flaky stuff, then paint w/bleach to kill fungus. Then apply water sealer, like DryLok. When that has set, cover it up w/masonry paint mixed w/a proper dose of mildewcide.

Only other solution I know is to make your house an island by installing french drains around entire perimeter. But you would still want to treat walls to stop the decomposition.

My opinion, anyway.

Left out that you'd probably want to patch walls and apply new skimcoat either befor or after sealant.
