CUSTOM BLDG SimpleSet Pre-Mixed Thin-Set Mortar 1 QT | No-Mix Interior Tile Adhesive

Effortless interior tiling with CUSTOM BLDG SimpleSet

Introducing the SimpleSet Pre-Mixed Thin-Set Mortar in a convenient 1 quart bottle. This no-mix formulation is designed to minimize mess from start to finish, so you can focus on precise alignment and clean edges. The ready-to-use mortar spreads smoothly and evenly, helping you achieve consistent coverage with less cleanup.

Whether you’re updating a kitchen backsplash, a bathroom wall, or a small foyer, SimpleSet offers a practical solution for interior tile work. The product is recommended for bonding porcelain, stone, marble, granite and ceramic or porcelain tile up to 8" x 8". Its versatility extends to larger one-sided tiles up to 15" on a side, though you should anticipate longer dry times in that scenario.

For lighter color stone and tile projects, choosing the white SimpleSet variant can help preserve the intended look by minimizing color variation and showing full tile tones. The mortar is designed for interior use on walls and floors, making it a streamlined option for compact spaces or DIY projects where speed and cleanliness matter.
