SikaShield® P24 PE IN

Atactic Poly Propylene (APP) modified bituminous membrane with PE foil and flexible at -2 °C (Formerly Sika® WP Shield-103 P)

DESCRIPTION

SikaShield® P24 PE IN 3 mm is an APP modified bituminous waterproofing membrane with a thickness of 3 mm. It is reinforced with a non-woven polyester fabric and is flexible at -2 °C. The top surface is coated with polyethylene foil, which ensures the bond of the overlying layer. The underside of the product has a burn-off film for easy torch-application. USES The product is used as a waterproofing membrane for: Balconies and terraces under a heavy protection layer such as tiles or gravel. ▪ Flat and sloping roofs under protective layers or ballast ▪ ▪ Car park decks ▪ Bridge decks under asphalt wearing layer ▪ Underpass and subways ▪ Basements and other below ground structures Horizontal reinforced concrete slabs, decks, podiums and protrusions ▪ ▪ Vertical reinforced concrete walls The product is used as a: ▪ Base sheet and/or top sheet in multi-layer systems Please note: The product is not suitable for roofs permanently exposed to UV radiation. Protect membrane with a suitable protection layer.

▪ CHARACTERISTICS / ADVANTAGES

▪ Fully bonded ▪ Long term flexibility ▪ Excellent water tightness Very good mechanical properties (tensile, tear, shear) ▪ ▪ Can be handled in warmer temperatures easily ▪ Low water absorption ▪ Easy to install by torching method Capable of withstanding thermal and structural stresses ▪ Good durability and performance under long term ageing ▪

Actual measured data may vary due to circumstances beyond our control. FURTHER DOCUMENTS Guidelines and good practice for torch-applied membranes ▪ Method Statement – Bituminous Membranes for Roofing Build-up ▪ Method Statement – Bituminous membranes for below ground ▪ ECOLOGY, HEALTH AND SAFETY User must read the most recent corresponding Safety Data Sheets (SDS) before using any products. The SDS provides information and advice on the safe handling, storage and disposal of chemical products and contains physical, ecological, toxicological and other safety-related data. APPLICATION INSTRUCTIONS Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions. SUBSTRATE QUALITY SYSTEM DESIGN Consider the following when designing the waterproofing system: The supporting structure must be of sufficient structural strength to support all new and existing layers of the roof and basement build-up. ▪ The membrane system for underground works must be considered for protection before structural concrete works. ▪ 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 PREPARATION

New concrete should be cured for at least 28 days and should have a pull off strength ≥ 1.5 N/mm2. Cementitious or mineral based substrates must be prepared mechanically to remove cement laitance and to achieve an open textured surface. Loose friable material and weak concrete must be completely removed and surface defects such as blowholes and voids must be fully exposed. The concrete must be carefully assessed for moisture content, air entrapment, and surface finish prior to any primer application. PRIMING Primer selection Note: For information on selecting the appropriate primer, contact Sika Technical Service. Apply the appropriate SikaShield® primer with the required consumption onto the prepared dry surface. Note: Refer to the individual Product Data Sheet of the primer. 1. Allow the primer to dry before membrane installation. 2. APPLICATION IMPORTANT Unrolling at low temperatures At low temperatures, the membrane becomes less flexible. Be careful when unrolling to avoid damaging the membrane.

IMPORTANT
Damage through footwear Footwear with spikes or sharp protrusions may puncture the membrane. Use footwear with a flat profile when walking over the membrane. 1. IMPORTANT Damage through overheating The polyester reinforcement melts at +260 °C. If it is damaged through overheating, the membrane becomes unusable. Keep moving the flame while torching to avoid overheating the membrane. 1. IMPORTANT Reduced adhesion through insufficient heating Make sure to heat the membrane sufficiently. If it is not sufficiently heated, the adhesion to the substrate, between layers or on the overlaps will be reduced. If the membrane does not adhere to other elements, lift and re-torch the unbonded areas. 1. Tackiness at high temperatures Note: When laying the membrane at high temperatures, the integral adhesive will become ‘tacky’ and may restrict laying operations.
ALIGNMENT IMPORTANT
1. Avoid coinciding joints To avoid coinciding joints, lay the membranes parallel to one another with staggering. When applying on another bituminous membrane, make sure to stagger the overlaps of the previous layer. 1. Unroll the membrane. 2. Align the membrane. 3. Re-roll the membrane before application. MEMBRANE OVERLAPS Overlap the membranes by a minimum of 80-100 mm on the sides and 150 mm on each end. 1. At the end overlap, cut off a corner measuring 80- 100 mm per side at an angle of 45°. 2. Weld the overlaps with great care until you see a trickle of melted mixture about 10 mm wide coming out along the line of the overlap. 3. TORCHING Heat the substrate and the backing film on the underside of the membrane with a gas burner. 1. When the backing film starts to melt, the membrane is ready to stick. 2. Roll the heated membrane forward and press it firmly against the substrate to bond it. 3. Make sure a bead of melted bitumen is visible along the full length of the overlap sides and ends when laying. 4. Suitable substrates for torching ▪ Concrete ▪ 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. 1. Refer to the relevant method statement for further information on detailing. MAINTENANCE Check the functionality of the auxiliary works, flash
could cause ponding on the roof and overload the drainage system. To maintain the function of the roof waterproofing membrane during its lifespan, it is advisable to arrange periodically for inspection of the membrane and detailing.
