Glass tile tragedy -- can it be saved?
Our contractor installed about 50 sq. ft. of Akdo glass tile (Frosted Seashell, 1" x 6" 'bricks') on our kitchen wall, using a standard unsanded cementitious grout. It looked superb. Then he applied sealant, and that is when our troubles began:
First he sprayed on TileLab (HomeDepot's brand) "Grout & Tile Sealer," covering the entire surface (tile as well as grout), and allowed that to dry for 48 hours. The grout looked fine, but the tiles were now covered with streaks of a cloudy film. He tried using dry microfiber cloth to remove this film, without success.
Next, he sprayed the entire surface with TileLab Gloss Sealer and Finish. He told us this would soften the streaky film so that he could remove it. That did not work. And worse, now our beautiful frosted glass tile was no longer frosted. The glass surface is now shiny and the tiles are nearly see-through (no longer translucent).
So our question is: can our (once) beautiful tile be restored?
