Siloxane solvent-based water repellent
BATIMIX Water Repellent 158 is a siloxane solvent-based compound. It is applied to concrete and mortar surfaces to minimize water penetration and efflorescence.
BATIMIX Water Repellent 158 is primarily formulated for waterproofing concrete, mortar, construction rocks, marble, mosaic, and various other substrates. It is used to block capillaries and pores of concrete and masonry. It provides effective water repellency protection of the treated materials. It is particularly suitable for waterproofing all calcareous building materials and sand-cement mixes. It is also used to treat rising damp in basements and tunnels.
BATIMIX Water Repellent 158 reduces the moisture regain of treated materials. It increases their lifetime by limiting the growth of moss. It helps control efflorescence, reducing sensitivity to freeze-thaw, and cutting down heat losses and cleaning costs. It effectively blocks the passage of water by penetrating the pores of the treated material. It allows the substrate to breathe as it does not affect the permeability to gases. The substrate is protected with one application.
BATIMIX Water Repellent 158 is not a hazardous material. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable gloves and goggles should be worn. For additional information, kindly refer to the product’s Material Safety Data Sheet.
The substrate can be either dry or damp but must be firm and free from grout, dust, dirt particles, oil grease and other impurities which can adversely affect uniform adhesion. Highly porous materials should be first treated by a filler bonding putty prior to application. BATIMIX Water Repellent 158 is applied in 1 or 2 coats using a brush, roller, or a low-pressure spraying device until the surface is fully saturated.
The material consumption is estimated at about 2 to 15 m² per kg, depending on the porosity and type of the substrate. BATIMIX Water Repellent 158 dries tack free in about one to two hours at 23 ºC.
Spray BATIMIX Water Repellent 158 uniformly until the substrate is saturated. On vertical surfaces where the run is very rapid, the surface should be kept wet as long as this is practical for maximum protection purposes.
Surfaces treated with BATIMIX Water Repellent 158 can be painted over. Light foot as well as wheel traffic should be avoided until the product has cured fully.
Tests have shown that performance of substrates against water penetration increases almost linearly with increased dosages rates of BATIMIX Water Repellent 158. However, the effect of overdosing may affect the color of the substrate.
BATIMIX Water Repellent 158 is compatible with all types of mortars and concrete made Portland cement, replacement materials such as silica fume, and other BATIMIX admixtures.
