We are tiling our kitchen back splash with travertine tile/ tumbled marble tile.Should we seal the tile before it is on the wall or seal it after it is on the wall?Thank you.
Seal the travertine after it's on the wall but before you grout. That will help keep the grout from sticking to the tile.
How dare you do that to your wall... The seal is an endangered species!!
Put the back splash tile on - then take a sponge and apply sealer to tile. Do not get sealer on edges that grout will fill in - put just on surface of tile. This will keep grout from sticking into small holes/dips in surface of tile. Let sealer dry good - then grout. Apply blue painters tape to edge of top up against wall to keep grout from getting all over the top. Apply about 2-3 strips of 2 blue painters tape here and also on any edges of wall cabinets/window trim etc. After grout is done and cleaned up - Apply grout sealer. Set first row of wall tile on a yardstick placed on the surface of the top. This will give you an even grout line starting off on the bottom. Use a *fast grab adhesive which will keep tile from sliding around. Take off any electrical covers and apply black electricians tape around the sides of the terminals on these receptacles/switches. Do a good job - take your time.
