Baltic Brown granite backsplash is very much like tiling over subfloor. Because Baltic Brown granite backsplash areas are smaller in total square feet than flooring projects, there are a few differences and limitations that you should keep in mind. using small tiles is easier in the long run than using large Baltic Brown granite tiles. Using acrylic mastic instead of thinset saves mixing time and is easier to spread over drywall. And using a cement backer board product is not always necessary. When using slate tile to cover a backsplash, sealing the slate after the grout cures is a must.
