As a water-repellent for absorbent mineral substrates:
Dilute Silway 744 is an excellent water repellent for many absorbent mineral substrates, such as bricks, sand-lime brick, natural sandstone and mineral plasters. It is not so suitable for less absorbent, dense natural stone, especially limestone, marble and reinforced concrete for bridges and roads.
High quality storage stability:Owing to its aqueous consistency and storage stability when diluted, Silway 744 is ideal for inplant impregnation of building materials made of clay, aerated concrete, sand-lime brick, fibrous cement, mineral fibers and lightweight aggregate. As a waterproof primer for paints:
Silway 744 may also serve as a water-repellent primer for emulsion paints and plasters, silicone resin emulsion paints and silicone resin plasters. Moreover Silway 744 can be used for the mass treatment of non-load bearing concrete products.
How to use Silway 744
Tap water is suitable for preparing solutions of Silway 744 for use as facade water repellent primer. We recommend an active substance content of 5-10% (dilute the product in the ratio 1:5 to 1:11), the exact figure depending on how absorbent the substrate is.
Apply the ready-to-use solution in the usual way; flooding is the preferred way. Two "wet on wet" coats are needed to ensure complete coverage. Owing to the content of wetting agent in Silway 744, reimpregnation at a later date does not present any difficulties.
