Application

Instructions

  • Surface Preparation : All surfaces must be sound and thoroughly clean before CHEMTILE 2K 77 is applied. All traces of grease or oil must be removed with suitable degreaser. All loose particles of mortar, old wallpaper, paint etc., must be physically removed. In case of cementations surfaces, the areas of application must be thoroughly wetted with water to obtain saturated surface dry condition. In case of smooth surfaces, prewetting of substrate with water is not essential.
  • Mixing : CHEMTILE 2K 77 should be mixed with water in the ratio of 3: 1 by volume or 4:1 by weight. While mixing, add powder And Liquid to the water to avoid lump formation. A slow speed drill fitted with a suitable mixing paddle is recommended for mixing. Hand Mixing may also be resorted to if small quantities are mixed. (Note: Use of chilled water in extreme temperatures will increase open time of CHEMTILE 2K 77).
  • Application : CHEMTILE 2K 77 is spread on the substrate to a uniform thickness of 4 to 5mm. This is then combed horizontally with a notched trowel. The tiles are then placed firmly into the adhesive bed ensuring good contact with the mortar by a twisting motion.
  • Finishing : The excess material shall be removed with a damp cloth before it sets. Joint grouting with CHEMAX TG Grout may be commenced 24 hours after tiles have been fixed.

Estimating

  • Packaging : CHEMTILE 2k 77 is supplied in 20 kg bag.
  • Coverage : Approximately 7.8 kg of CHEMTILE 2K 77 is required per sq.m when uniformly applied at 4mm thickness. Material consumption will increase if the substrate is not even.
  • Shelf life : 6 months in unopened bags under normal warehouse conditions. CHEMTILE 2K 77 must be stored in a cool dry place.
