Product Description:
SikaBit® PRO P-30-0 SAND 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: sand.
Usage:
Waterproofing membrane for:
- Damp proofing of the exterior walls of basements against percolating water and damp soil
- Flat roofs under protective layers or ballast
- Balconies and terraces under tiles
- Wet areas
- Protection of various substrates in a wide range of applications.
Features / Advantages:
- Good watertightness
- Good elongation and cold flexibility
- Good mechanical properties (tensile, tear, shear)
- Good resistance to impact
- Easy to install by torching method
- Choice of primers to suit substrate and weather conditions
Shelf Life:
- 12 months from the date of production
Storage:
- Store properly in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C.
- Store in a vertical position.

Application Guide:
Substrate Preparation:
- The supporting structure must be of sufficient structutal 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.
Application Guide:
Step 1 : Priming
Apply appropriate primer to the prepared dry surface and allow to dry before next application stage.
Step 2 : Alignment
Unroll, align, and re-roll correctly before torching.
Step 3 : Overlaps
Side : 80mm , End : 150mm
Step 4 : Torching
Use a gas burner to heat the substrate and the backing film on the underside of membrane. When the backing film starts to melt, the membrane is ready to stick.
Step 5 :
Roll the membrane forward and press firmly against the substrate to bond. Ensure a bead of melted bitumen is visible along the full length of the overlap sides and ends when laying.
Step 6 : Detailing
All details such as internal and external corners, upstands, vent pipes, drains, support metalwork etc. must be cut and sealed effectively.
