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.
