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
