The Hilti® GX-3 Vapor Barrier Fastener is a professional-grade tool for securely installing vapor barrier and insul barrier on crawl space walls and pillars. Unlike tape alone, this method provides a more permanent and structured hold that lasts.

The GX-3 uses Vapor Barrier Washers – Hilti GX-3 (placed on the magnetic tip) along with Vapor Barrier Nails – Hilti GX-3 to drive the washer and barrier directly into block walls or pillars. Simply fasten every 16 inches for a tight, long-lasting seal.

Extras for Best Results:
For a fully sealed system, apply Foundation Butyl Tape at the top of the wall before fastening. This creates a continuous seal between the nails and vapor barrier, locking out moisture and air for added protection.
