Description

A single component polymer modified cementitious tile adhesive for bonding homogenous vitrified tiles and ceramic glazed tiles on both internal and external area.

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 the adhesive.
  • Weak concrete and/or cement laitance must be removed. Repairs to the substrate, filing of blowholes / voids, etc. must be carried out using SikaTop® or Sika® MonoTop® range of products.
  • Painted surface must be scabbled / abraded to expose 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 the screed/render level is plumb to achieve optimum adhesive bed thickness.
  • Certain non-absorbent surfaces can be easily prepared for tiling by using Davco Bonding Agent. Please refer to Davco Bonding Agent product data sheet for further details.
  • Wash and remove the release powders at the back of porcelain tiles.
