Dulux AcraTex 501/8 AcraPrime HAR

Code: 194-85772

DULUX AcraTex 501/8 AcraPrime HAR Primer is a Low VOC ,Water Based primer/sealer designed specifically for the preparation of fresh "green" masonry surfaces. Reduces unsightly white salts or "efflorescence" migrating through the applied coating system and speeds project coating schedules by reducing traditional concrete/render "Alkalinity passivation" delays.

Features

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

Benefits

  • Fast tracks coating application over green concrete
  • Ensures good, uniform adhesion of topcoat
  • Consolidates masonry surfaces
  • Environmentally sound system

Use and typical specification

AcraPrime HAR Primer can be used over all masonry surfaces 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 and reducing overall project costs.

Typical properties and application data

Application Guide DULUX AcraTex 501/8 AcraPrime HAR may be applied by roller, conventional or airless spray. A brush is required to cut in around edges and obstacles. Typical airless set-up: Graco Ultra 500 using 0.011-0.013 spray tip at approx. 1000 psi. For full details refer to individual Duspec Product and AcraTex Applicational Data Sheets.
