Sto Corp. Introduces Sto RapidGuard™

April 16, 2018

Atlanta, GA – (April 16, 2018) Sto Corp., the innovative world leader in claddings, air barriers, coatings, and restoration systems, announces the introduction of Sto RapidGuardTM.  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.

“The material is fast-drying, and its flexible coverage makes it easy to provide high-quality air and moisture control across multiple applications,” said Karine Galla, Product Manager for Sto Corp.  “It gets the job done quickly and enables applicators to finish their work despite potentially adverse weather conditions.”

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.

Sto RapidGuard has excellent 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 Sto 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.

Sto RapidGuard is available now in the US & Canada.
