Usage

  • Davco® Supamastic can be used for residential internal thin bed wall applications with porous tiles (>3% absorption) on porous substrates.
  • Davco® Supamastic can be used for residential internal dry area floor tiling application with porous backed tiles (>3% absorption) on porous substrates - primed Cement Sheet/Ceramic Tile Underlay.
Please note: If you are uncertain of the porosity of the tiles you are fixing use Davco SMP Evo adhesive or seek technical advice from Sika Australia. Refer the the Davco SMP Evo product data sheet for additional information. Suitable substrates include:
  • Fibre cement sheet
  • Plasterboard
  • Ceramic tile underlay
  • Rendered blockwork & brickwork
  • Davco K10 Plus waterproof membrane (drying times will be greatly extended over waterproof membrane, therefore only of fixing of porous backed tiles ≥3%)
  Suitable Tile Types include:
  • Ceramic
  • Mosaic
  • Natural stone not sensitive to moisture
Not suitable for use with porcelain tiles greater than 200x200 size. For these applications use Davco SMP Evo adhesive.

APPLICATION

Laying the Tiles

  1. Place the adhesive onto the prepared and primed substrate. Do not apply more adhesive than can be tiles within the open time of the product, usually from a single tile to 1m2.
  2. Hold the notched trowel at an angle of 60° or greater to the substrate.
  3. Spread the adhesive over the required area where tile is to be applied, comb the adhesive in a single direction (not swirls).
  4. Where "back buttering" the tile is required, use the flat side of the notched trowel to apply a thin adhesive layer to the back of the tile (approx 1-2mm thick).
  5. Place the tile into the combed adhesive and press the tile firmly.
  6. Move the tile forward and then back at 90° across the direction of the combed adhesive to flatten the adhesive to leave no voids under the tile. Occasionally life a tile to check the adhesive covers 90-100% of the tile.
  7. Remove any excess adhesive in the joints, and on the face of the tile with a sponge and water while the adhesive is still wet.
  • Do not allow the adhesive to skin prior to placement of the tiles. If the adhesive skins, remove and replace.
  • Application shall be in accordance with AS3958:2023 The Installation of Ceramic and Stone Tiles.
  • Movement joints shall be installed in accordance with applicable standards.
  • Back buttering the tiles may be required to achieve minimum coverage requirements.
  • Allow the adhesive to dry prior to grouting.

CLEANING OF TOOLS

Clean tools and equipment with water prior to adhesive drying.
