Sto announces the introduction of Sto RapidGuard. The new product is a single-component, multi-use air barrier and waterproofing material that seals rough openings, seams, sheathing joints, cracks, penetrations, and transitions in above-grade wall construction. Costly shutdowns due to rain can be avoided because Sto RapidGuard adheres to damp substrates without blistering or increasing drying time. The product can even be installed down to near-freezing temperatures. The product has strong elongation, allowing it to bridge cracks and seams in wall construction without tearing or compromising the established air and moisture barrier. It works seamlessly with waterproofing air barrier membranes, and is compatible with concrete, concrete masonry, brick, gypsum sheathing, wood, galvanized material, and cement-based sheathings. Because it is a single-component product, there is no need for tape, mesh or fabric, and it can be easily applied without the use of special tools or applicator training. The product is available now in the US & Canada. For more information, please visit www.StoCorp.com.
