Silblock WMS masonry water repellent, an aqueous emulsion based upon silane technology, is an excellent candidate to consider for outstanding water resistance as an admixture and/or penetrating sealer. When Silkblock WMS masonry water repellent is added as an integral water repellent during the concrete mixing process (admixture), it can significantly reduce water absorption and efflorescence. When used as a sealer for masonry, it can offer deep penetration resulting in excellent surface protection from water, rain, and de-icing agents and potentially providing resistance to chloride intrusion of masonry substrates. Examples of masonry substrates that can be benefited are concrete blocks, pavers, stucco, and porous or dense brick. In both applications, Silblock WMS masonry water repellent can help improve the freeze-thaw resistance significantly.

Features and Benefits of Silblock WMS
- Can help reduce capillary water absorption in masonry applications
- High alkali resistance
- Offers flexibility in applications. Outstanding water repellent as an integral blend/admixture or surface treatment (penetrating sealer)
- Can help provide excellent protection against deterioration caused by freeze-thaw cycling, chloride ion intrusion, efflorescence, and water penetration
The contact angle of distilled water droplets was measured on a treated concrete surface. Silblock WMS masonry water repellent showed a very slight beading effect on concrete. If a more significant beading effect (or contact angle about 100 to 110 degrees or higher) is desired, the addition of paraffin wax emulsion or fluorocarbon resin emulsion is required. In general, beading effects are not considered as a true measure of the efficacy of water repellency.
