SikaBit® PRO P-40-0 PE

Plastomeric Modified Bituminous Waterproofing Membrane

SikaBit® PRO P-40-0 PE is an APP modified, bituminous, torch-applied, waterproofing membrane. It is reinforced with a dimensionally stable non-woven polyester inlay. The underside has a thin polyethylene burn-off film for easy application. It can be applied to wood, metal and concrete substrates including over existing bitumen roofing membranes. Top surface finish: polyethylene film. Thickness: ~4,0 mm

  • Good watertightness
  • Good elongation and cold flexibility
  • High mechanical properties (tensile, tear, shear)
  • Good resistance to impact
  • Easy to install by torching method
  • Choice of primers to suit substrate and weather conditions

Application steps

SUBSTRATE QUALITY

The supporting structure must be of sufficient structural strength to apply all new and existing layers of the waterproofing build-up. When used as a roofing membrane, the complete roof system must be designed and secured against wind uplift loadings.

The substrate must be uniform, firm, smooth and free of any sharp protrusion or burrs, clean, dry, free of grease, bitumen, oil, dust and loosely adhering particles.

SUBSTRATE PREPARATION

Use the appropriate preparation equipment to achieve the required substrate quality.
