I have new tile and it was down a couple of weeks before we moved in. Of course, the tilers left us to seal it, which we did not do until we moved in and the house had been thoroughly cleaned. I used a product from Lowe's and went over my bathroom twice, kitchen once (so far) and I swear I am already seeing stains and water seems to be soaking in. Should it bead up? I'm worried I've done all this work for nothing and the grout may already be ruined. Some spots my steam cleaner won't clean out, nor any cleaner I've used so far. I'm sure I probably need more than 1-2 coats. Any advice??
