I am doing a backsplash project with 12x12 mosaic travertine tile on mesh
Some of the 2x2 tiles have holes and imperfections which I hope to fill with grout which is the same color as the tile
I am planning to seal the tiles before I adhere them to the walls.............
My question is if the tile is sealed with 511 impregnator sealer prior to adhering to the wall will the grout adhere to the holes?
Should I fill in the holes before I seal the tiles?
