ClassicBond PRO Water Cut Off Mastic is a one part butyl blend mastic designed to be used in conjunction with EPDM roofing and waterproofing systems. It is primarily used for sealing between membranes when installing a compression type seal. Water Cut Off Mastic is extremely tacky and will remain as such when not under compression.
For use in a compression termination, this is used in a variety of situations where a compression termination of the ClassicBond PRO membrane is required.
- Each tube covers 3 linear metres
- This is only to be used as a compression type mastic, not as a sealant for wall chases or gaps
