haze in pits?

[Michael Monteforte]

Just completed a large kitchen area with 2'x2' rectified edge tile. everyone was very happy(builder, architect, designer). Because it was a glazed tile, i did not bother to seal it before grouting. we cleaned the floor very well. only after the floor completely dries, tiny pits filled with residue become apparent. Cleaned with a light vinegar solution and I called the laticrete rep. he said to wait 10 days, then use sulfamic acid and the grout should release from the small holes. I believe the tile is somwhere around $15 a sq ft. Please Help!!!!!

Eeeuwww,i had the same problem on some tile did what they suggested you do, cept i used a buffer and stiff nylon pad,you could use an acid brush, but it is pretty hard to get it all out,be warned.

Dave ,They recomended letting the sulfamic acid solutin on the for 20 min in order for it to realy work. What kind of buffer did you use?

[Davestone]

Just a regular buffer you can rent one at HD.20 minutes may be a little long, might etch the tiles.You will have to trial and error this a little to find the right time and right method with the pads or brushes,a wetvac helps a lot, and don't forget to rinse.
