Kerakoll Aquastop Fabric Waterproof Membrane

Description

Kerakoll Aquastop Fabric Waterproof Membrane is a low thickness, polyethylene vapour barrier waterproofing membrane coated on both sides with high adhesion polypropylene fabric. Measuring 1 metre in width, it is available in 30 linear metre rolls or per custom metre length.

Kerakoll Aquastop Fabric is for waterproofing damp environments and environments with high vapour presence before laying ceramic tiles, porcelain tiles, mosaics and stone materials with gel adhesives. It’s anti-fracture, high elasticity and expansion/tearproof characteristics reduces the stress in the overlying covering and makes it ideal for use as an anti-cracking waterproofing system/composition for areas with moderate stress.

Kerakoll Aquastop Fabric Waterproof Membrane can be quickly bonded to all substrates with gel adhesives from the Kerakoll H40 range in order to create a waterproof vapour barrier resistant to alkaline environments and chemical aggressions in uses with higher humidity and presence of water vapour.

Kerakoll Aquastop Fabric provides a barrier against the passage of vapour from extremely damp or water vapour-saturated environments (showers, bathrooms, saunas) to the substrates and the adjacent areas, guaranteeing the durability over time of those construction elements that could be affected by this phenomenon. The core of the membrane is a Polyethylene (PE) film approximately 0.3 mm thick with a high co-efficient of resistance to the diffusion of water vapour (μ > 300,000) corresponding to a thickness of the Sd diffusion-equivalent air layer of 122 m; the membrane is classified according to UNI 11470 as a vapour barrier screen (Sd ≥ 100m).

Kerakoll Aquastop Fabric Waterproof Membrane is designed for internal and external use, on swimming pools, walls and floors, to waterproof and create a vapour barrier before laying ceramic tiles, natural stone and mosaic coatings. Kerakoll Aquastop Fabric Waterproof Membrane can be used in showers, bathrooms, kitchens, saunas, Turkish baths, damp environments, balconies, terraces and flat roofs.

Kerakoll Aquastop Fabric can be used on the following substrates: Screeds and mineral plasters/renders, existing ceramic, marble floor tiles, natural stone floorings anchored to the substrate, cured concrete, plasterboard, wood, fibre-cement and gypsum fibre panels anchored to the substrate. The membrane is also specifically designed for waterproofing substrates based on Tile Backer Boards to avoid individual treatments of joints.

Do not use Kerakoll Aquastop Fabric on bitumen, metal; to waterproof uncoated surfaces subject to foot traffic, or as a vapour permeable membrane; for exposed applications; on damp substrates or substrates subject to moisture rising. In general, refer to the chapter “Do not use” in the technical data sheet of the gel adhesive to be used for laying the membrane.

Application Instructions:

1. 1. Unroll the sheets of Kerakoll Aquastop Fabric and cut them to measure, leaving a space of approximately 5 mm between one sheet and the next as well as between the sheets and the construction elements. Make cuts and holes to measure on the sheets where there are pipes or drains in order to allow for the correct application of the membrane.
   2. Apply Kerakoll H40 Gel or Advanced gel adhesive using a suitable toothed spreader and adjust the thickness tilting the spreader and using its toothed part. Apply the gel adhesive to a surface area that will allow laying of the sheets within the open time indicated (check the state of the adhesive frequently). Avoid any build-up of gel adhesive that might compromise the flatness of the sheets.
   3. Position the sheets or unroll them onto the fresh gel adhesive, taking care they are flat and avoiding the formation of creases or bubbles.
   4. Immediately press the Kerakoll Aquastop Fabric down onto the fresh gel adhesive using a smooth spreader and press properly to ensure that the membranes are taut. Take care not to damage the sheets with the edges of the metal spreader so as not to compromise the watertightness and vapour seal.
   5. Lay the next sheet of Kerakoll Aquastop Fabric , aligning it with the preceding one and leaving a gap of approximately 5mm between one sheet and the next; press immediately, being particularly careful when using the spreader along the edges of the sheets.
   6. Proceed as illustrated for bonding the sheets to the floor.
      Notes – When laying Kerakoll Aquastop Fabric on wood, metal, rubber, PVC, linoleum and fibreglass, use Kerakoll H40 Extreme Adhesive. – When laying the membrane on existing floors and coatings, check for integrity and adhesion.
   7. Waterproof the joints between the sheets and internal and external corner angles using Kerakoll Aquastop 120 Tape and Corner Pieces with Kerakoll Aquastop Fix Waterproofing Sealant. Seal the outer edges of the surface, starting from the corners. Apply Aquastop Fix on the edges of the membranes using a smooth spreader. Be careful to completely fill the joint between the sheets. Then position the Aquastop 120 corner piece/tape on the fresh sealant.
   8. Press firmly and smooth over the tape to ensure it adheres perfectly, being careful not to wrinkle it. The white mesh side strips and the first 5-10 mm of the green tape must be completely covered with sealant.
