SikaShield® P55 MG Testudo 4,5 kg/m²

Plastomeric bituminous membrane surfaced with mineral granules and flexible at -15 °C (Formerly Index Testudo Mineral)

SikaShield® P55 MG Testudo 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 -15 °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
  • Can be painted immediately after application
  • Easy to install by torching method
  • Highly flexible in cold temperatures
  • Fully bonded
  • Very good mechanical properties (tensile, tear, shear)
  • 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

Primer selection

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