Sto Corp. has announced a one-component material designed to seal sheathing joints, seams, cracks, and transitions in above-grade wall construction.

The product, RapidFill, is an addition to the StoGuard air- and moisture-barrier line.

StoGuard RapidFill can fill gaps and cracks up to one-half inch wide, the manufacturer reports.

Sto says RapidFill is compatible with most common building materials, including concrete, concrete masonry, brick, gypsum sheathing, wood, galvanized metal and cement-based sheathings.

RapidFill may be applied in cold and humid weather to fill cracks up to one-half inch wide.

The manufacturer says that RapidFill may be applied on damp surfaces, in cold weather, and in high humidity. Rapid drying time allows for same-day installation of other air-barrier components, the company says.

RapidFill provides "an easier, faster way to construct a seamless air barrier," John Chamberlin, Stoguard product manager, said in a product announcement.

The product may be used with other StoGuard membranes, including Sto Gold Coat (StoTherm NExT Systems), Sto EmeraldCoat, Sto AirSeal and Sto VaporSeal.

Atlanta, GA-based Sto Corp. produces a broad range of cladding and coating systems for building construction, maintenance and restoration.
