I am going to do a backsplash in 4 x 4 tumbled travertine. I understand this needs to be sealed. Is there any reason I cannot "dunk" or submerge them in sealer before I install them. I think this would be a better way to insure all the pits get sealed.
My other question is can I cover the face of the tile with tape or contact paper so I can grout with a float.
Any thoughts or experiences would be appreciated.
