Ceramic Tile Mastic

Choosing An Organic Mastic Adhesive

Although inferior to a quality thinset mortar, top quality projects can be achieved using an organic mastic adhesive.

• Avoid using organic mastic adhesives for floor installations.
• Bows, dips, and waves on finished sheetrock and ceramic tile backerboard panels should be repaired prior to installing ceramic tile.
• Never use organic mastics adhesives to install bathroom fixtures or marble sills. Use a non-sanded thinset mortar or other appropriate bonding agent instead.
• We recommend the use of Type I or better water resistant organic mastic adhesives.
• Manufacturers have varying methods for mixing and installing their product. These instructions should always be carefully followed.
