Silicone Water Repellent

DESCRIPTION

Brinlay Silicone-based water repellent is formulated to protect and maintain the natural beauty of all types of masonry. It overcomes discolouration due to water carrying dirt into the pores of the masonry, and helps overcome efflorescence due to the lack of penetration of water into the masonry. Prevents growth of moss, fungus and mould by maintaining masonry in a dry condition. It is supplied as a water white thin liquid, it dries clear and does not stain, discolour or alter the texture of the masonry. It is designed for exterior application to all types of masonry surfaces including brick, cement, asbestos cement sheeting, natural stone work, etc., and may be used on interior masonry surfaces which may require protection from water spilling.

SURFACE PREPARATION

Surfaces must be prepared according to standard painting procedures. Surfaces to be treated must be thoroughly dry, cleaned to remove all efflorescence, and all mould or moss deposits treated. Do not use detergents when cleaning, as traces of these materials will definitely effect the water repellency of the following silicone treatment.

APPLICATION

Brinlay Silicone Water Repellent may be applied by brush or spray. The surfaces must be clean and thoroughly dry. Apply a generous quantity of water repellent to the surface, ensuring that the coverage figures quoted below are not exceeded. Since the water repellent is perfectly clear, a second application is recommended after 24 hours to ensure complete protection of the masonry surface.
NOTE:- Brinlay Silicone Water Repellent takes at least 24 hours to develop its full water repellency. Drying time varies with weather conditions. Application in very cold and wet weather is inadvisable. Surface to be treated should be dry and not treated in less than 7 days after rain. The product is not suitable for use on painted surfaces or slate. It should not be applied to new unseasoned concrete or cement work.

DRYING TIME: Allow up to 24 hours before re-coating.

THINNING: Thinning is not recommended. Clean up may be effected with mineral turps.

COVERAGE: Coverage can vary with the porosity of the surface. As a general rule, the coverage can be as low as 2 square metres per litre on soft, very porous material and up to a maximum of 5 square metres per litre on harder masonry.
NOTE:- Provide adequate ventilation during application and curing.

When spraying Brinlay Silicone Water Repellent, the use of a flooding technique is recommended, using just enough pressure in the spray gun to give a non-atomising stream. When applying Brinlay Silicone Water Repellent, a run down of about 25cm on the surface should be aimed for.
