Sika Black Jack DPM is a rubberised bitumen emulsion suitable for interior and exterior use. It’s a highly effective sandwich damp proof membrane for floors, but equally reliable as a waterproofer for walls, above ground structures and foundations.

Black Jack damp proof membrane dries black and forms an impervious barrier to water and water vapour on most surfaces – it’s ideal for general waterproofing jobs on fibre cement, render or plaster.

This versatile DPM can also be used as an adhesive for fixing wood blocks and wooden mosaic flooring, as well as insulation boards, expanded polystyrene and cork slabs. It can even be used as a bonding agent for plastering difficult substrates, or as a curing agent for concrete.
