Surface Preparation

The surface to be tiled must be completely sound and clean, dry and dust free. Any surface contaminants like grease, oil and efflorescence must be removed in order to promote adhesion. Gypsum based boards must be primed first with RABINDER or RAPRIMER and allowed to dry for 8 hours.



RABOND FLEX should be mixed with a mechanical paddle mixer on a low speed setting to achieve a smooth and lump free consistency. Mix in a clean bucket using approximately 7-8 litres of clean water per 25Kg bag. Allow the mixture to stand for 5-6 minutes and then remix thoroughly before application. Use a notched trowel to apply the adhesive. Curing time is approximately 4-5 hours.



Do not use RABOND FLEX

  • On surfaces that are wet
  • When temperatures are below +5°C and over +35°C
  • With underfloor heating
