• Easily applied water repellent treatment giving a self-cleaning, hydrophobic surface to masonry, concrete
and asbestos sheeting.
• Excellent water repellent
• Excellent resistant to UV light.
• Minimizes efflorescence and prevents growth of fungus.
• Economical and very easy to apply
• Prevents entry of moisture into the walls, but allows the surface to breathe.
• Colorless hence maintains natural color of walls.


WATERREPELL S is a ready to use, silane-siloxane based repellent which penetrates in concrete or cementitious substrates pores, providing an effective water repellent protective coating. Its UV resistant properties make the film durable for outdoor use. The use of silicone retards or prevents changes in the surface appearance by resisting the deterioration effects occurred due to atmospheric attack. Due to its excellent water repellent properties, dirt and other atmospheric impurities are washed off by rain and it’s clean appearance is maintained for a longer period. Also, WATERREPELL S prolongs the clear appearance of buildings and minimizes efflorescence.


WATERREPELL S is suitable for external application to exterior walls of brick or concrete blocks, cement renderings, asbestos cement, concrete and all types of stone, including limestone. Also used as an injection damp coarse fluid and provides a durable barrier to water penetration of porous surfaces.

It is non-glossy and will not alter the color or surface texture of the natural substrate. This architectural grade sealer is 100% water vapor permeable and, unlike solvent-based products, is not hazardous. Water repellent S prevents moisture from seeping into concrete and also keeps damaging ice melting compounds from penetrating into concrete, making it especially ideal for use in parking garages where de-icing chemicals are required in order to protect from extreme moisture.


Surface Preparation: All surfaces to be treated must be sound, clean and dry. Any defects and cracks, other than hair line cracks, should be made good. Dirty surfaces should be thoroughly cleaned and organisms such as algae or lichens should be removed. In no circumstances should detergents be used as they may reduce the efficiency of the treatment. The surface should be allowed to dry before the application of WATERREPELL S. WATERREPELL S should not be applied over mastics surfaces Glass, etc. should be protected against splashing during application.
Application: WATERREPELL S is supplied ready to use. Apply by brush or low pressure spray. The WATERREPELL S should be applied liberally so that it runs freely down the surface to about six inches below the point of application. When applying by spray, the pressure should be kept as low as possible to avoid excessive misting, and the nozzle held close to the surface. After application of WATERREPELL S, it dries within a few hours and becomes fully resistant to water in 24 hours. Brushes, spray equipment, etc. may be cleaned with water.


Packing: WATERREPELL S is available in 1, 5, 10, 50,100 liters carboys.

Coverage: 1Ltrs of WATERREPELL S will cover approx. 4 to 5 m2 of surface depending upon porosity and surface texture. Normally one coat is sufficient.
