Sika® SikaMix Integral Waterproofer is a liquid/gel additive that provides long term protection from water damage to mortar, renders and screeds by dramatically reducing water permeability. This product is suitable for all applications where resistance to water damage is necessary, such as pool and tank linings, roof areas, external rendering/pointing and structures below ground level. SikaMix Integral Waterproofer also contains an air entraining agent, hence it will not 'deaden' the mix and there is no need to add a separate admix.
