Application Information

Consumption

• 0.15–0.25 L/m² per coat (4–7 m²/L) on power-trowelled concrete
• A second coat is required on porous, rough-textured, or brush-finished surfaces

Application Steps

• Substrate – Fresh Concrete (≥7 days): Finish using power floating, manual floating, or tamping. Cure for at least 7 days with water spray, blankets, or plastic sheets.
• Substrate – Hardened/Old Concrete: Clean with high-pressure water cleaner. Allow to dry completely. Remove all dust, dirt, and loose material with brush or vacuum.
• Important – Remove Existing Treatments: Completely remove any curing agents, membrane-forming sealers, or asphalt before application.
• Application: Apply in a continuous film using a high-volume, low-pressure spray unit. Do not use sprayers previously used for silicones or release agents. Touch up any dry spots immediately.
• Scrubbing: Scrub material into the surface with a soft bristle broom or floor-scrubbing machine for minimum 30 minutes until the material begins to gel and becomes slippery.
• Reworking: Wet the surface slightly with water spray and rework for another 10–20 minutes.
• Removal of Excess: After ~20 minutes when material returns to a gel, rinse the floor and remove excess with a squeegee, wet vacuum, or mop. Dried residue leaves white stains removable only mechanically.
• Second Coat: Apply on porous or rough surfaces after the first coat is dry and tack-free.
• Before Subsequent Coating: After cure, abrade the surface mechanically (light to heavy shot blasting) before applying any subsequent coating system.
• Hot Weather (>+25°C): Store product in a cool place. Apply additional material to keep surface wet during scrubbing.
• Moisture Protection: Protect treated surface from moisture for at least 3 days after application to prevent efflorescence.

SikaShield P24 MG 4.5 kg/m²

SikaShield P24 MG is an APP modified bituminous roof waterproofing membrane by Sika, reinforced with non-woven polyester fabric. The mineral granule top surface provides permanent UV resistance and a decorative finish, torch-applied via burn-off film for a fully bonded, seamless installation.

Specifications

Product Features

• Decorative mineral granules — UV resistant for permanent outdoor exposure
• Torch-applied via burn-off film for easy, fully bonded installation
• Flexible at 0°C — suitable for varying temperature conditions
• Good mechanical properties: tensile, tear, and shear resistance
• 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.
