Liquid Housewrap

Sto’s fluid-applied air and moisture barrier is a spray-on housewrap that works to protect structures from air leaks and water intrusion. The StoGuard product is a fully adhered, seamless, vapor-permeable air barrier system that doesn’t require nails, screws, or staples to attach it. The liquid air barrier can be used under various exterior claddings including fiber cement, vinyl, brick, and stucco and is three times faster to install than traditional housewraps, significantly reducing labor costs, according to Sto
