Question We just installed a porcelain tile floor in kitchen using 18" honed thesaurm tile imola. We grouted with sanded grout and the floor looks great but after a week or so when the sun would shine on the floor you would see dull water spots on floor. Regular cleaning would not take them up. We tried viniger and water and some grout haze cleaners that did not work. The store recomended Tecbanish and that worked but the dull spots eventually came back not sure if they are the same spots. Does honed porcelain mean that it is all natural with no polish or glaze or is there a protective shipping polish? Im not sure how to go about trying to get this problem fixed or is the tile ruined or can it get ruined? does it need a sealer?
Thanks for the help
Answer Hi John,
I'm sure the tile isn't ruined. It sounds like you are trying some of the right things. These spots may be a residue from the latex in the thinset. Using a sealer is not a bad idea but I would first try first to remove the water spots.
As far as using vinegar, I don't know how strong you used it but I would first try a strong solution again. Maybe 1 gal. to a 5 gal. bucket of water (4 to 1). If that don't work a mild acid wash. But using acid should be done by a professional or done with extreme caution. I use a masonry cleaner acid called,
"Sure Klean Detergent 600" they also make a "Grout & Tile Cleaner" http://www.prosoco.com/ProductDetail.asp?ID=%7B3DD244A3-CBD3-44DA-8368-C1C4EC52F...
Acid wash must be added to the water to avoid splashing. Safety protection must be worn. acid must never be applied to metals or woods of any kind. Mixing, about 16 to 24 oz. to 3 gal. of water. Using a sponge wet a small 3"x3" area, scrub blue nylon scrub pad, remove excess solution with the sponge. After the floor has been cleaned rinse with clean water, add to the rinse water 2oz of baking soda per 1 gal. of water.
After the floor completely dries and you are satisfied with the results then I would seal the tile and grout. I use "Miracle Sealants 511 Porous Plus" http://www.miraclesealants.com/s_porous_plus.html
John, I hope this answer will be of som help to you. Please feel free to write back with any other questions you may have.
