How important is it to repair cracked grout?
Very important. Cracked grout can easily let elements into the spaces between the tile and the mortar, which will eventually result in tiles coming loose or falling off. In addition, cracked grout can easily become missing grout, which can then result in a ruined installation in half the time. Repairing cracked grout before it goes missing is definitely worth either the time it takes to do it yourself or the expense it takes to have it done professionally. Why can’t I use my ceramic tile products on my natural stone tile? There are some products that can be used on practically any surface, however many cleaning products that are specifically designed for ceramic tile are typically harsher and can damage both the natural stone and the sealer. Most ceramic tile cleaners you get at the grocery store will have acid or alkaline, which are never appropriate for natural stone. Some professional cleaning products can be used on both ceramic tile and natural stone, but only if properly diluted.
