Applications & Uses

Application Instructions

Surface preparation

• All surfaces should be clean, dry, and free from frost, grease, and loose materials.
• When cleaning contaminated substrates, HS Butyl recommends using propan-2-ol (IPA) and allowing it to dry before applying the butyl tape.

Application

• Apply directly from the reel onto one surface and press along its entire length to ensure good initial adhesion.
• Overlap the tape ends to ensure a good seal and compress.
• Remove the backing paper, position the other surface onto the sealant, and push firmly to seal across the joint.
• Spacers may be inserted into the tape to prevent over-compression.

Product Application

Sealing concrete caisson rings, box culverts, manhole sections.
