HELP! Screwed up sealing bathroom floor
Tiled bathroom floor. Looks great. Used a light grout, the color was called Canvas. It was supposed to be a medium beige, but actually turned out quite light. But we like it.
It's been a week since grouted, and was putting sealer on today by brushing the grout lines with an artist brush. Had to leave, so I left the cup of sealer sitting on the floor and came back two hours later to resume. Sealer had eaten through plastic cup and seeped into several long grout lines. There was about 3/4 of a cup of sealer in the cup, so that's a lot that seeped in. The places where it seeped are very dark. REAL dark. Everywhere else that I just brushed sealer on looks just like the grout did before sealing. Light. I was hoping as it dried it would get lighter, but it's been about 6 hours and no change. I have the dehumidifier going in there. I tried blowing with a hairdryer.
The sealer says it is "a penetrating siloxane water repellent. For brick, ceramic tile, clay tile, concrete and grout lines. Intererior and exterior use. A transparent film to seal out water, stain and dirt." I don't know if we're allowed to say product names on here, so I've given the description.
Is there any chance this will lighten up? Or if it was going to, would it have done so by now?
If it doesn't lighten, what should I do? Scrape the grout out in the dark spots and redo? There's about 8 linear feet of grout lines that are dark.
And how do you get grout out?
