SikaShield® E54 PE 3 mm

SikaShield® E54 PE 3 mm

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

SikaShield® E54 PE 3 mm is a 118 mils thick SBS-modified bituminous 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.

  • Double reinforcement
  • Does not require a cant strip
  • 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

  • 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.
  • 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

To avoid coinciding joints, lay the membranes parallel to one another, align it properly, ensure the specified overlaps are followed, and then re-roll it before application.

                     

MEMBRANE OVERLAPS

        

  • Overlap the membranes by a minimum of 4" (100 mm) on the sides and 6" (150 mm) on each end. 
  • At the end overlap, cut off a corner measuring 4" (100 mm) per side at an angle of 45°.
  • End laps must be staggered 18'' (46 cm) apart.
  • Offset cap sheet side and end laps so they are positioned at least 12'' (28 cm) away from any base ply laps.
  • A mininum 20 lb (9 kg) roller must be used on all side and end laps, following immediately behind the heat welding. Apply uniform pressure across the lap area while the bituminous compound is warm to ensure a positive bond.
  • A continuous bead of asphalt approximately 1/4 inch wide should be visible at all laps after application.
  • The edge of the seam must be left untooled (not buttered).

 

IMPORTANT: DO NOT STACK LAPS!

       

 

  

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

 

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.
