Roof sealing compound DD

The special sealant to fill joints between bitumen sheeting

The fischer roof sealing compound DD is ideal for grouting connections and penetrations in roofs, walls and floors, for sealing and bonding work in the case of leaks in roof sheeting, and for carrying out safe repairs. The bitumen-based sealant has a high adhesion capacity even on substrates that are damp with rain, which means that work does not need to be interrupted. fischer DD is non-corrosive and can be used on aluminium, copper and zinc-plated surfaces.

Product Description

  • The special bitumen-based formulation seals roofing membranes and roofing felt securely. This guarantees long-lasting functionality.
  • DD also holds to moist substrates without a base layer. This makes application largely independent of the weather and thus helps to avoid interruption of work.
  • DD is non-corrosive, and thus can be used on aluminium, copper, zinc-plated surfaces and polystyrene. This offers maximum flexibility.
