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.

  • Remove the backing paper, position the other surface onto the sealant, and push firmly to seal across the joint.
