Double-Sided Bond

Tacky butyl rubber bonds permanently to both foundation wall and polyethylene vapor barrier—prevents sagging and maintains vertical seal integrity.

Masonry Compatible

Sticks tenaciously to concrete block, poured concrete, and masonry surfaces when applied with construction adhesive—works on various wall types.

Moisture Resistant

Butyl rubber formulation maintains adhesion in high-humidity crawl space conditions—won't deteriorate or lose bond strength over time.

Complete Encapsulation

Essential final step for wall liner attachment—completes the continuous moisture barrier from floor to wall for comprehensive crawl space protection.

Permanent Wall Liner Bond

Beast Butyl Tape is a professional-grade, double-sided butyl rubber tape designed for attaching vapor barrier wall liner to crawl space foundation walls during encapsulation projects. At 1 inch wide and made from tacky butyl rubber, this tape creates a permanent, moisture-resistant bond between vertical surfaces and polyethylene sheeting—essential for completing a fully sealed crawl space encapsulation system.

Professional Installation Method

Apply construction adhesive (we recommend Loctite PL375) to the foundation wall in a continuous bead where you want the tape positioned. Press the butyl tape firmly into the adhesive and allow to dry completely. Peel away the protective backing and press your vapor barrier wall liner onto the exposed sticky surface. This two-step method creates an exceptionally strong bond that handles the weight of vertical poly without sagging or failure.

Installation Best Practices:

  1. Clean and prepare foundation wall surface (acid wash if needed)
  2. Apply construction adhesive in continuous bead at desired height
  3. Press butyl tape firmly into adhesive
  4. Allow adhesive to cure per manufacturer instructions
  5. Peel protective backing from butyl tape
  6. Press vapor barrier wall liner firmly onto exposed tape
  7. Use hand roller for maximum contact
