Our house was built in 1957. We recently tore up the vinyl floor in the entryway to see what was underneath with the intention to either restore what was there if it was in good enough shape, or to have the floor re-tiled.
We found the original mosaic tile floor from when the house was built, hiding under a thick layer of embossing leveler. None of the tiles were cracked or broken, or even loose.
We managed to soften and scrape up the leveler but the floor still has an annoying white residue on it that I can't seem to get rid of no matter what I do.
Here is what I have tried so far:
Diluted white vinegar
Straight white vinegar
Grout haze remover
Acidic tile cleaner (contains hydrochloric acid)
Buffing with dry cloth
Polishing pad attached to power sander
So far the acidic tile cleaner has been the most effective but it requires multiple applications to even see a difference and the tiles and grout are still hazy. It looks great when it's wet but once it dries, the haze returns.
Does anyone have any advice on what else I can try? Should I throw in the towel and call in a professional? If so, what type of professional...a cleaner, or a tile laying expert? Can this floor be saved? I would really like to save it; my house has a lot of its original features and surfaces and I am a big fan of the era. I would really
like to keep this floor.
Thank you in advance!
