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 Silblock® 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.

Performance Data

Silblock WMS masonry water repellent was tested for capillary water absorption on concrete. This was compared to the performance of a competitive silane as well as a Calcium Stearate treatment. Silblock WMS proved to be the most effective treatment to reduce capillary water absorption.
