Davco TTB 98 is an economical thin or thick bed cementitious tile adhesive ideal for fixing ceramic tiles, natural stones and most monocottura tiles at interior and exterior walls and floors.

Surface Preparation
  • All surfaces must be structurally sound, dry, clean and free from movement, oil, grease, wax, curing compound and any other loose or contaminating materials.
  • Dusty concrete or masonry should be swept clean and dampened with water prior to the application of adhesive.
    Weak concrete and/or cement laitance must be removed.
  • Repairs to the substrate, filing of blowholes / voids, etc. must be carried out using appropriate products from the SikaTop® or Sika® MonoTop® range of material.
  • Painted surface must be scabbled / abraded to the original substrate. Newly rendered / screeded surface must be thoroughly cleaned prior to tilling and have a wood float finish.
  • Old rendered / screeded surface must be thoroughly cleaned prior to tilling and have a wood float finish.
  • New concrete must be allowed to cure for at least 1 month and have a wood float finish. Steel trowel finished concrete must be mechanically abraded prior to tilling.
  • Old concrete surface must be thoroughly cleaned prior to tilling. Make sure all release agents are removed from concrete surfaces, especially on tilt-up slabs.
  • Screeds should be allowed to dry out as slowly as practicable after curing to reduce the risk of curling.
  • Cement-sand, and fine concrete levelling screeds should be cured for at least 7 days and be subjected to continuous air drying after curing for at least 2 weeks before the tiles are laid. Please refer to BS 5385 or MS 1294.
  • To ensure screed/render level is plumb to achieve optimum adhesive bed thickness.
  • Certain non-absorbent surfaces can be easily prepared for tiling using Davco Bonding Agent. Refer to Davco Bonding Agent data sheet for further details and suitability.
  • Wash and remove the release powders at the back of porcelain tiles.

This depends on the level, profile and surface roughness of the substrate, the size of the tiles and the technique of placing (simple placing or "back"- buttering).
As a guide, in kilogram of powder per m² on flat surfaces:

Mosaics and small tiles
~2.0–3.0 kg/m² using 3 mm x 3 mm notched trowel

Normal size tiles (20 cm x 20 cm)
~5.0–5.5 kg/m² using 6 mm x 6 mm notched trowel

Large size tiles up to 3 600 cm² (internal floors) and 2 100 cm² (external floors)
~10.0–11.0 kg/m² using 12 mm x 12 mm notched trowel

The consumption above may only serve as a guide. It is highly recommended to carry-out trials on site to determine the actual coverage.
