Effectively seals the joints between Delta DualProof External Membrane sheets, as well as being ideal for other applications across a range of substrates.

CEM 805 DualProof Adhesive

The CEM 805 DualProof Adhesive provides a permanent and powerful seal for interior and exterior joints, including Delta DualProof external pre-applied membranes. This sealant is ideal in construction joint waterproofing as it’s hydrophilic, meaning that it expands when it comes into contact with water. It’s also odourless, solvent and silicone free, and resistant to chemicals. 

When applied, this waterproof adhesive reacts with moisture in the atmosphere, creating a seal of elastic vulcanized rubber. This particular rubber is stronger and more rigid than natural rubber, whilst retaining a flexible, elastic form. This results in a powerful seal for internal and external joints. 

Please note: When used for DualProof External Membranes, three tubes of DualProof CEM Adhesive are recommended per roll of Delta DualProof Membrane

Delta 805 DualProof Adhesive Applications

Delta’s CEM 805 adhesive can be used in a number of applications, including:

  • Sealing metal, wood, plaster, ceramic, plaster and concrete structures
  • Also suitable for aluminium and galvanised steel
  • When overlapping Delta DualProof External Membrane
  • Gluing construction foils
  • Green roofs

Applying CEM 805 DualProof Waterproof Adhesive

Before applying the adhesive, clean the surface of any dust, particles and release agents. You do not need to use a primer before use, especially on glass or glazed surfaces. 

If using as a bonding agent, the waterproof adhesive should be applied as a bead. 

Please note that, if applying on a painted surface, we recommend testing the product’s compatibility first.
