Application

Application Information

Application Steps

• Substrate Preparation: Surface must be uniform, firm, smooth, and free from sharp protrusions, grease, laitance, oil, dust, and loose particles. Must be clean and dry.
• Priming: Apply the appropriate Sika® primer at the required consumption onto the prepared dry surface. Allow the primer to dry completely before membrane installation. Contact Sika Technical Service for primer selection guidance.
• Alignment: Unroll the membrane and align it. Re-roll before application. Lay membranes parallel to avoid coinciding joints. When applying over another bituminous membrane, straddle the overlaps of the previous layer.
• Torching: Heat the substrate and the burn-off film on the underside of the membrane with a gas burner. When the backing film starts to melt, roll the membrane forward and press firmly against the substrate. Keep the flame moving to avoid overheating (polyester reinforcement melts at +260°C). A bead of melted bitumen must be visible along the full length of all overlaps.
• Overlaps: Overlap sides by min. 100 mm and ends by min. 150 mm. At end overlaps, cut a 100×100 mm corner at 45°. Weld overlaps until a 10 mm trickle of melted mixture is visible along the overlap line.
• Detailing: Use a sharp knife to cut around internal/external corners, upstands, vent pipes, drains, and support metalwork. Refer to the relevant method statement for detailing guidance.
• Suitable Substrates for Torching: Concrete, perlite screed, bituminous membranes with smooth surface, compatible coatings, brick masonry, cementitious screeds.
• Footwear: Use flat-profile footwear only – spikes or sharp protrusions may puncture the membrane.

• Can be painted immediately after application
• Tiles can be placed directly onto the membrane
• Suitable for flat or sloping roofs (up to 15% gradient), balconies, and terraces
• Use as exposed cap sheet in a multi-layer waterproofing system

Application Steps

• Substrate Preparation: Surface must be uniform, firm, smooth, and free from sharp protrusions, grease, laitance, oil, dust, and loose particles. Must be clean and dry.
• Alignment: Unroll and align the membrane, then re-roll before application. Lay membranes parallel to avoid coinciding joints. When applying over another bituminous membrane, straddle the overlaps of the previous layer.
• Torching: Heat the substrate and the burn-off film with a gas burner. When the backing film starts to melt, roll the membrane forward and press firmly. Keep the flame moving to avoid overheating (polyester reinforcement melts at +260°C). A bead of melted bitumen must be visible along all overlaps.
• Overlaps: Overlap sides by min. 100 mm and ends by min. 150 mm. At end overlaps, cut a 100×100 mm corner at 45°. Weld until a 10 mm trickle of melted mixture is visible along the overlap line.
• Detailing: Use a sharp knife to cut around corners, upstands, vent pipes, drains, and support metalwork. Use flat-profile footwear only — spikes may puncture the membrane.

Application Information

Application Steps

• Substrate Preparation: Surface must be uniform, firm, smooth, and free from sharp protrusions, grease, laitance, oil, dust, and loose particles. Must be clean and dry.
• Priming: Apply the appropriate Sika® primer at the required consumption onto the prepared dry surface. Allow the primer to dry completely before membrane installation. Contact Sika Technical Service for primer selection guidance.
• Alignment: Unroll the membrane and align it. Re-roll before application. Lay membranes parallel to avoid coinciding joints. When applying over another bituminous membrane, straddle the overlaps of the previous layer.
• Torching: Heat the substrate and the burn-off film on the underside of the membrane with a gas burner. When the backing film starts to melt, roll the membrane forward and press firmly against the substrate. Keep the flame moving to avoid overheating (polyester reinforcement melts at +260°C). A bead of melted bitumen must be visible along the full length of all overlaps.
• Overlaps: Overlap sides by min. 100 mm and ends by min. 150 mm. At end overlaps, cut a 100×100 mm corner at 45°. Weld overlaps until a 10 mm trickle of melted mixture is visible along the overlap line.
• Detailing: Use a sharp knife to cut around internal/external corners, upstands, vent pipes, drains, and support metalwork. Refer to the relevant method statement for detailing guidance.
• Suitable Substrates for Torching: Concrete, perlite screed, bituminous membranes with smooth surface, compatible coatings, brick masonry, cementitious screeds.
• Footwear: Use flat-profile footwear only – spikes or sharp protrusions may puncture the membrane.

Maintenance

• Check the functionality of auxiliary works, flashings, drainage outlets, and overflow pipes regularly.
• Remove leaves, moss, and vegetation that could cause ponding and overload the drainage system.
• Arrange periodic inspections of the membrane and detailing to maintain waterproofing performance throughout its lifespan.

Application Information

Application Steps

• Substrate Preparation: Apply adhesive mortar SikaShield® W1 onto the water-saturated concrete substrate while still wet. Refer to the SikaShield® W1 PDS for full substrate condition requirements.
• Alignment: Unroll the membrane and align it. Re-roll before application. Lay membranes parallel to avoid coinciding joints. When applying over another bituminous membrane, straddle the overlaps of the previous layer.
• Wet Application: Lay the membrane directly over the wet adhesive mortar. At one end, peel away part of the release liner from the underside. Bond this end to the adhesive and substrate. Continue peeling the liner sideways while bonding the rest of the membrane.
• Rolling: Roll the applied membrane surface with a roller from the centre to the edge to remove air bubbles. Push any excess adhesive towards the opposite direction of the sealed side overlap.
• Overlap Sealing: If ambient temperature is below +10°C, seal membrane overlaps by heating with a gas torch or hot air to ensure proper adhesion and prevent adhesive trapping under the overlap.
• Curing & Backfilling: Allow adhesive mortar to cure for at least 24 hours at +25°C before backfilling. Complete backfilling within 7 days of application.
• Detailing: Use a sharp knife to cut around internal/external corners, upstands, vent pipes, drains, and support metalwork. Refer to the relevant method statement for detailing guidance.
• Footwear: Use flat-profile footwear only – spikes or sharp protrusions may puncture the membrane.

Application Information

Application Steps

• Substrate Preparation: Surface must be clean and sound. May be dry or damp but free of standing water. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, and disintegrated materials. Concrete: sandblast or use other approved mechanical methods. Steel: sandblast to white metal finish (SA 2½).
• Mixing: Pre-mix each component separately. Proportion 2 parts Component A to 1 part Component B into a clean pail. Mix thoroughly for 3 minutes with a paddle on low-speed drill (400–600 rpm) until uniform in colour. Mix only the quantity that can be used within the pot life.
• Application: Apply Sikadur®-732 evenly onto the prepared substrate at 0.3–0.8 kg/m² using a brush, roller, or trowel. Place fresh concrete or structural element onto the adhesive while it is still wet and tacky. For bolt/dowel grouting, inject or pour into the hole and insert the bolt immediately.
• Important Notes: Do not exceed the pot life. Do not add solvents or thinners. Protect from rain and moisture until fully cured.
