Damp Proofing

What's the best product to stablise crumbling standstone walls?

Hi several of my outside house bricks (made of sandstone) are crumbling away at a dramatic rate. These are primarily the bottom bricks of the outer wall of my cellar. The cellar is rather damp, although it has been tanked out recently, which I think hasn't helped the crumbling brickwork. I have tried applying stabilising solution to the bricks (Everbuild 406) which I thought might work. However, this has caused a paper like coating to form on top of the bricks which peels away on touch, taking the yellow colour of the sandstone and leaving a grey coloured stone. I am currently trying to find a stone mason to replace the really badly affected bricks, but would like to buy a product to protect the other bricks from crumbling? Is there anything that people would recommend? Thanks
