Larpruf PW

Larpruf PW is a powder waterproofer and hydrophobic admixture for concrete, semi-dry mixes and mortars.

It can be used in all types of mortar and concrete to reduce water permeability and absorption, and to impart water-repelling properties. Larpruf PW is particularly suitable for use in semi-dry precast products such as paving, concrete facing blocks, bricks and mortars.



  • Water permeability and absorption reduced
  • Vapour permeable – allows structure to ‘breathe’
  • Helps prevent efflorescence
  • Reduces frost damage
  • No significant effect on strength
  • Permanent effect as the concrete weathers


Packaging: 10kg bags
