SKU: Davcoflex 666 Category: Brand:
  • Enhanced adhesion of low-porosity tiles to dense impervious substrates
  • Easy to mix, just add water
  • Extensive range of applications for interior and exterior wall and floor installation

A single component flexible polymer modified cement based adhesives specially intended to meet the challenging requirements of modern tilling. Specially formulated for large format fully vitrified tiles, marble & granite.

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 repair material from the 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 tiles are laid. Please refer to BS 5385 or MS 1294.
  • Ensure screed/render level is plumb to achieve optimum adhesive bed thickness.
  • Non-absorbent surfaces can be easily prepared for tiling using Davco Bonding Agent. Refer to Davco Bonding Agent product data sheet for more details.
  • Release powders at back of porcelain tiles must be removed by washing with clean water.
