Description

An environmentally economical thin bed (up to 10mm) or thick bed (more than 20mm) adhesive mortars. It is especially designed with approved recycled materials and is recognized by Singapore Environmental Council under their Green Label scheme. Also for use with Portland cement mix with fine silica sand to make bond coats to mortar beds and for dry set mortars to give improved performance and longer open time.

Surface Preparation
  • All surface must be structurally sound, dry, clean and free from movement, oil, grease, wax, curing compound and any other loose or contaminating materials.
  • Expansion joints coinciding with joints in the substrate should be incorporated at the design stage at a maximum of 5m spacing and must be tiled over.
  • Movement joints must be incorporated where necessary in accordance with the general principles incorporated within the BS 5385: Part 1-4.
  • Dusty concrete or masonry should be swept clean and dampened with water prior to the application of mortar.
  • Painted surface must be scabbed/ abraded to expose at least 80% of the original substrate. Newly rendered/screeded surface must be thoroughly cleaned prior to stone laying and have a wood float finish.
  • Old rendered/ screeded surface must be thoroughly cleaned prior to stone laying and have a wood float finish.
  • New concrete must be allowed to cure for 6 weeks and have a wood float finish. Steel trowel finished concrete must be acid etched or mechanically abraded prior to tiling.
  • Old concrete surface must be thoroughly cleaned prior to tiling. 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 and 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 tiling is applied. Please refer to BS 5385 or MS 1294.
  • To ensure screed/ render level is plumb to achieve optimum adhesive bed thickness.
  • Certain non-absorbent/ contaminated surfaces can easily be prepared for tiling via use of Davco Bonding Agent. Refer to Davco Bonding Agent data sheet for further details and suitability.

[Note: Do not soak ceramic tiles. Porcelain tiles with too much of release powders at back of tiles must be washed and clean well. Skim the back of the tiles to ensure optimum coverage. Prior to installation for external tiling, protect from direct hot sun and rain by means of shelter. It is the user’s responsibility to determine the condition and suitability of all surfaces prior to application.]
