Tiling a shower wall & Tiling a floor - Need help

Question

I put 6x6 ceramic tiles in my tub/shower area & grouted it too, how long does the grout need to sit before I can seal it? How long do I wait after sealing it to use the shower? I installed 12x12 ceramic tiles on a very small bathroom floor, how long does that grout need to dry before it can be walked on & does it need to be sealed like the other, if so how long does that sealer take to dry? Thanks for any advice you can give me.

Answer 1

  Your best over all sealer is a pentatring sealer.. It can be used on all grout in 72 hours.. Tiles must be clean of all dust and grout residue.1 quart is enough to do 2 coats. (recommended) 1 coat and an hour later a 2nd. 24 hrs ready to be used.. Grout will set up generally in a few hours  but your safer to walk on it  the next day..HD  carries a sealer that I ve used for years to seal  stone tiles before setting..Comes in a green bottles and costs about 30 $ and it s called Surfacegaurd Pentatrating Sealer by Tile Lab GL

Answer 2

Usually 24 hours for both but why not just check the labels ??
