SimpleMat® Tile Setting Mat

The quickest, easiest, and cleanest way to install tile on countertops, backsplashes and shower walls. SimpleMat® replaces traditional thin-set mortar or mastic adhesive. SimpleMat retains its bonding strength for extended periods of time, which means users have the flexibility to tile onto the mat an hour at a time or over several days. SimpleMat® bonds instantly so you can start grouting immediately.

Environmental Consideration

Custom® Building Products is committed to environmental responsibility in both products produced and in manufacturing practices. Use of this product can contribute towards LEED® v3 certification:

  • Up to 2 points towards MR Credit 5, Regional Materials
  • Up to 1 point towards IEQ Credit 4.1, Low-Emitting Materials – Adhesives & Sealants

Suitable Tile Types

  • Ceramic, porcelain or stone tile larger than 1" x 1" (2.5 x 2.5 cm).
  • Gauged stone tile (uniform thickness) that is no thicker than 1/2" (13 mm) or more than 5 lbs. per square foot.
  • Mosaic tile with an open mesh backing as long as the shortest side of the tile is at least 5/8" (1.6 cm).

Suitable Substrates

  • Kitchen or bath counters, walls, backsplashes and shower walls.
  • Tile over drywall, plywood, WonderBoard® Lite, backerboard, concrete, painted surfaces, laminates and existing tile.

General Surface Prep

Surfaces must be structurally sound, clean, dry and free from grease, oil, dirt, curing compounds, sealers, adhesives or any other contaminant that would prevent a good bond. All surfaces to be tiled should be flat, even and stable (i.e. no cracks, peeling, or surface movement). SimpleMat™ will follow your wall or counter surface, so patch, flatten or level as needed.

Health Precautions

SimpleMat® employs an aggressive adhesive to perform its function. Ensure that SimpleMat® is not placed over the nose or mouth and is kept away from hair.

Limitations to the Product

  • Not for use on floors, on ceilings, shower floors or in areas constantly exposed to water.
  • Tiles should be relatively flat on back to make full contact.
  • Limited adjustability.
  • Not recommended for outdoor use.
  • Not for use with any tile greater than 8" x 8" or heavier than 5 lbs.

Bonding to Concrete Surfaces

Concrete or plaster must be fully cured and accept water penetration. Test by sprinkling water on various areas of the substrate. If water penetrates, then a good bond can be achieved. If water beads, surface contaminants are present and loss of adhesion may occur. The contaminants should be removed before installation. Concrete must be free of efflorescence and not subject to hydrostatic pressure.
