It inhibits the passage of liquid water through the capillary and pore network in cementitious materials, but does not form a vapour barrier thus allowing the structure to breathe. Prufplast is non-retarding, chloride-free and equally compatible with all cements. Use in render base coats also reduces the suction to allow easier application of following render coats.

• Combined waterproofer & plasticiser
• Ideal for use in external renders
• Vapour permeable – allows structure to ‘breathe’

Packaging:
5L and 25L packs

By increasing the water repellency but maintaining the vapour permeability of a mix, there is a lower water absorption, lower risk of efflorescence and staining and a higher durability. Use of Powder Waterprooofer in render base coats also reduces the suction to allow easier application of following render coats

• Permeability and absorption reduced
• Vapour permeable – allows structure to ‘breathe’
• Helps prevent efflorescence
• Easy to use

Packaging:
1kg plastic bags

Coverage:
1kg per 50kg cement

It inhibits the passage of liquid water through the capillary and pore network in cementitious materials, but does not form a vapour barrier thus allowing the structure to breathe. Pink Waterproofer is non-retarding, chloride-free and equally compatible with all cements. Pink Waterproofer is not suitable for use in areas where there is hydrostatic pressure.

• Integral waterproofer
• Ideal for use in external renders

It inhibits the passage of liquid water through the capillary and pore network in cementitious materials, but does not form a vapour barrier thus allowing the structure to breathe. Caltra Integral Waterproofer is non-retarding, chloride-free and equally compatible with all cements. Caltra Integral Waterproofer can be used to waterproof screeds, renders and concrete, which when treated will resist hydrostatic pressure. It is also suitable for use in render systems used to tank basements or to line water-retaining structures.

• Colourless, non-staining and non-toxic
• Non-flammable
• Ideal for use in areas of poor ventilation
• Light traffic after 24 hours
• Economical and easily applied
• Can be over-coated
• Approx. 45% efficiency

Packaging:
25L and 200L packs

Coverage:
Approx. 4-5m2/l per coat
