SikaShield® E54 PE 3 mm

SikaShield® E54 PE 3 mm

118 mil SBS-modified bituminous base ply, torch-applied

SikaShield® E54 PE 3 mm is a 118 mil thick SBS-modified bituminous waterproofing membrane. It is reinforced with a non-woven polyester fabric dimensionally stabilized with fiberglass and is flexible at -0.4°F (-18°C). The top surface is coated with a smooth surface, which ensures the bond of the overlying layer. The underside of the product has a burn-off film for easy torch application or a non-woven polypropylene fabric for cold or hot application.

  • Double reinforcement
  • No cant strip needed
  • Excellent dimensional stability
  • Easy to install by various methods (torch, cold and mop)
  • Fully bonded
  • High durability
  • Good mechanical properties (tensile, tear, shear)

Application steps

SUBSTRATE QUALITY

SYSTEM DESIGN

Consider the following when designing the system:

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

  • If used as a roof system, the complete system must be designed to withstand and be secured against wind uplift loadings.

      

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.

APPLICATION

ALIGNMENT

To avoid coinciding joints, lay the membranes parallel to one another. When applying on another bituminous membrane, make sure to straddle the overlaps of the previous layer.

  1. Unroll the membrane.
  2. Align the membrane.
  3. Re-roll the membrane before application.

           

MEMBRANE OVERLAPS

  1. Overlap the membranes by a minimum of 4" (100 mm) on the sides and 6" (150 mm) on each end or as specified by the supplier.
  2. At the end overlap, cut off a corner measuring 4" (100 mm) per side at an angle of 45°.

              

TORCHING

  1. Heat the substrate and the backing film on the underside of the membrane with a gas burner.
  2. When the backing film starts to melt, the membrane is ready to stick.
  3. Roll the heated membrane forward and press it firmly against the substrate to bond it.
  4. Make sure a bead of melted bitumen is visible along the full length of the overlap sides and ends when laying.

               

Suitable substrates for torching

  • Concrete
  • Perlite screed
  • Bituminous membranes with a smooth surface
  • Coatings (check the compatibility)
  • Brick masonry
  • Cementitious screeds

            

FASTENING

When used as a roofing sheet, the membrane can be mechanically fixed to the substrate by using the correct type of fasteners.

The number of fixings, type and position depend on wind uplift forces to be resisted, pull-out strength of the fixing screws, the elastic limit of the membrane and the appropriate safety factors.

Contact Sika Technical Service for additional information.

           

Suitable substrates for fastening

  • Concrete
  • Wood
  • Metal
  • Perlite screed
  • Bituminous membranes
  • Coatings (check the compatibility)

           

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.
