Peeling floor tiles?
“My floor tiles keep on peeling and the glue has turned into a white powder.” Just like paints, tile adhesives are attacked by alkalis from the concrete. Lift and discard the tiles. Then, remove the adhesive. Floor strippers are available in hardware stores, e.g. citric acid (delemonene) or use our paint & mastic remover . Or rent a floor sander or a grinder. Older tiles may contain asbestos, which means you have to use a stripper. Today’s adhesives on self-stick floor tiles are water-based. But moisture in the air will penetrate through the joints, condense on the concrete, activate the lime in concrete and dissolve the glue. RadonSeal will stop the moisture coming in through the concrete and neutralize alkalis, extending the life of the tiles.
