Tech-Dry® T-Silox is a solvent-free, 100% silane/siloxane concentrate. It is designed to be used to produce solvent-based water repellent masonry/ concrete sealers after dilution with an organic solvent.

When diluted with an appropriate solvent, T-Silox is recommended for the colourless water repellent treatment of masonry substrates including concrete, cement mortar and renders, fired bricks, tiles and grout and/or natural stones. T-Silox can also be used as a damp-coursing fluid after dilution with a proper organic solvent for the installation of silicone damp-courses.

T-Silox may also be incorporated into solvent-based acrylic systems to produce products that are useful for impregnating or coating. Concrete sealers are useful for preventing various stains and degradation. For more information, download the T-Silox data sheet.
