SikaShield® P44 MG Fidia 4,5 kg/m²

Plastomeric bituminous membrane surfaced with mineral granules and flexible at -10 °C

(Formerly Index Fidia Mineral)

SikaShield® P44 MG Fidia 4,5 kg/m² is an APP modified bituminous roof waterproofing membrane with a weight of 4,5 kg/m². It is reinforced with a non-woven polyester fabric dimensionally stabilised with glass fibre and is flexible at -10 °C. The top surface is coated with mineral granules, which allows the permanent exposure to UV radiation. The underside of the product has a burn-off film for easy torch-application.

  • Decorative mineral granules
  • Easy to install by torching method
  • Fully bonded
  • Flexible in cold temperatures
  • Good mechanical properties (tensile, tear, shear)
  • Can be painted immediately after application
  • Tiles can be placed directly onto the membrane

Application steps

SUBSTRATE QUALITY

SYSTEM DESIGN

Consider the following when designing the roof system:

  • The supporting structure must be of sufficient structural strength to support all new and existing layers of the roof build-up.

  • The complete roof system must be designed to withstand and be secured against wind uplift loadings.

  • The wind uplift resistance of the adhered roofing assembly is limited by the adhesion strength of the Product to the substrate.
     

SUBSTRATE CONDITION

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

SUBSTRATE PREPARATION

PRIMING

  • Apply Sika® Igolflex P primer at a rate of 6-8m2 per litre. Note: Consumption rates will vary depending on substrate type and porosity.
  • Allow the primer to dry before membrane installation

APPLICATION

IMPORTANT

  • At low temperatures, take care unrolling to avoid damaging the membrane.
  • Use suitable footwear to avoid puncturing the membrane.
  • Do not apply to wet, damp or unclean surfaces.
  • Do not over-torch the membrane otherwise the polyester reinforcement (which melts at 260 °C) will be damaged making the membrane un-useable.
  • If membrane is insufficiently heated, this can cause reduced adhesion to the substrate, between layers or on the overlaps. If this occurs, un-bonded areas must be lifted and re-torched.
  • If a seasonal symbol is printed on the roll’s label, it is advisable to use the membrane during the indicated season.

ALIGNMENT
Unroll, align and re-roll correctly before torching.


OVERLAPS
Side: 100mm. End: 150 mm.


FASTENING
Fidia Polyester when used as a roofing base sheet, can be mechanically fixed on the substrate by using the correct type of fasteners. Contact Sika Technical Services for additional information. 

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. Roll the membrane forward and press firmly against the substrate to bond. Ensure a bead of melted bitumen

DETAILING

Use a sharp knife to cut in all details such as internal and external corners, upstands, vent pipes, drains, support metalwork etc.Refer to the relevant method statement for further information on detailing.
