Preparing surface for tiling
Jut finishing off the tiling in my kitchen and I have only the window
box left to do. The Plaster surface was a bit uneven and raw so I have sealed it with a PVA solution and let it dry. Suddenly wondered if that was the right thing to do? Or Am I going to have to scrape it back to bare plaster? |

Tile cement has incredible bonding properties, and will probably stick to it OK (at least the powdered stuff; I've never used ready-mixed so I can't comment on that). When PVAing under plain sand and cement, you should apply the sand and cement to a layer to still tacky PVA. However, tile cement contains its own bonding agents and prefers a dry background, so I think it should be OK on dried PVA, although I wouldn't have put the PVA on in the first place. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |
