Able to last as long as five years on interior grout and three years on exterior grout safecoat grout sealer is a formaldehyde free clear liquid that coats and moderately penetrates porous tile.
Sealer for natural stone backsplash tiles and grout.
It is wise to apply the sealer to your natural stone tile before grouting and once again the day after grouting.
If over time your stone tile stops deflecting water you will need to apply sealer again.
With some grouts that can be even worse with it needing sealer.
Let the sealer penetrate the stone for.
Use broad overlapping strokes working from top to bottom to prevent drips.
Failure to do this can lead to the grout chipping and coming off over a short amount of time.
Porcelain and ceramic tiles are not porous.
Using solvent based sealer will prevent you from have to re seal as often.
Dip a foam paintbrush into the sealer and paint the sealer onto the backsplash.
Seal the tile not the grout many tiles especially natural stone such as slate marble and limestone are porous and need to be sealed.
