We have 2 rooms with quarry tile that has been down approximately 30 years. I would like to clean it and possibly seal it. Is there a machine I can rent like a floor cleaner & buffer? This tile is industrial type with a rough surface. If I go to all the work to get it clean I would like to seal it. But have read that you have to reseal it every year??? Do you have to strip it off to reseal?? I don't want to start another maintenance project!

I just finished tiling my 500 sq. ft. kitchen, panty and bfst. nook... after reading a lot of literature on it. I opted not to remove the existing linoleum as the hardiboard backing web site said the backing board could be installed over Vinyl Composition Tile ... which I thought my floor was. (I think I just wished it was). I removed the vinyl linoleum (same type) from the bathrooms and they were most definitely sheets, not tile. When I installed the backing board I cemented and screwed as the directions instructed. My question, what do I have to look forward to due to my placing the backing board on the linoleum? (even though its cemented and screwed) Thanks, TomRogers
