FEBPROOF PLUS 5LT

For screeds, mortars and non-structural concrete rendering. Conforms to BS4887.

Improved workability
High resistance to water
Reduces incidence of efflorescence

Product Descriptions

Febproof plus reduces water absorption and makes mortar or non-structural concrete less permeable. Due to its strong air-entraining plasticiser, the water cement ratio is much lower for the same workability. Febproof plus has been tested to the requirements of EN 934 Part 3.


Typical Uses

Febproof plus is suitable for use in rendering finishes and pointing mortars. It is also used in reconstructed stone and non structural concrete members.

Features & Benefits

Improves weathering properties.

Reduced suction aids pebble dashing - larger areas covered easily.

Improves water resistance.

Reduces onset of efflorescence.

Improved application properties.

Supplements / replaces lime.

Drying shrinkage, crazing and cracking reduced.

Improved frost resistance.

Febproof plus contains a highly hydrophobic material which is dispersed throughout the mix and thus reduces moisture penetration.

Febproof plus also entrains air and this reduces capillary and water channel development, thus ensuring greatly increased water tightness and resistance to frost. In addition, due to its plasticising action, reductions in water content of up to 20% are attained. Febproof plus slightly retards the mix, e.g A 3:1 sand/cement mix will be retarded by about an hour.
