DULUX AcraTex GREEN RENDER SEALER is a Low VOC ,Water Based primer/sealer designed specifically for the preparation of fresh 'green' Cement Render. Reduces unsightly white salts or 'efflorescence' migrating through the applied coating system and speeds project coating schedules by reducing traditional cement 'wait' times - Safe to Paint Render after only 2 days.


  • Superior water and alkali resistance
  • Seals and primes masonry surfaces
  • Penetrating binder
  • Water based, Low VOC


  • Fast tracks coating application over green cement render
  • Ensures good, uniform adhesion of topcoat
  • Consolidates masonry surfaces

AcraTex Green Render Sealer is specifically designed for use of new cement render to provide excellent system adhesion and integrity with long term durability. The primer forms a barrier over alkali substrates limiting the reaction with atmospheric Carbon Dioxide thus reducing the formation of unsightly white deposits or 'efflorescence' on the surface typically associated with coating of highly alkaline fresh masonry. The primer allows for reduced substrate curing time prior to coating, thus fast tracking project works.
