Feb Febproof Plus Waterproofer and Plasticiser reduces water absorption and makes mortar or non-structural concrete less permeable. As a strong air-entraining plasticiser, the water to cement ratio is much lower for the same workability. This intern improves water and frost resistance as well as the onset of efflorescence. Leaving a finish that is less likely to experience shrinkage, crazing or cracking. Suitable for use in rendering finishes and pointing mortars. It is also great for use in reconstructed stone and non-structural concrete members, external rendering, special finishes, roughcast, stucco, reconstructed stone and pebble-dashing due to the reduced suction enabling large areas to be covered easily.
