An acrylic dispersion designed for use in cementitious coatings. It increases the water-repellency of the coating as well as improving adhesion, abrasion resistance and flexibility.
To a standard 3:1 plaster mixture use WeatherBond Enhance at a rate of 5 litres per bag of cement when wetting the mix. The plaster is then applied in the conventional manner. Care should be taken to clean application implements immediately after use with clean water. In severe cases eg. Balconies or underground structures, the mixing rate can be increased to 10 litres per bag of cement. Can be used with cement powder to seal ponds, dams and reservoirs. Can be spray applied onto suitable prepared metal surfaces as a primer top coat (Interior of potable metal water tanks). For this type of application the ratio of WeatherBond Enhance to cement should be 1:3. Add the cement powder to the WeatherBond Enhance with stirring and mix till a smooth paste is produced.
