Mapei Mapelastic Aquadefense Tanking Kit

Description The Mapei Mapelastic Aquadefense Tanking Kit is a ready to use kit for the rapid waterproofing of bathrooms, wet rooms and showers to receive tiles after 4 hours. It is comprised of a 7.5kg tub of Mapei Mapelastic Aquadefense Tanking Membrane and a 10m roll of Mapei Mapeband PE120 Waterproofing Tape. The Mapei Mapelastic Aquadefense Tanking Kit is used to form waterproofing layers before applying ceramic, stone and mosaic coatings in: bathrooms and shower cubicles; wet rooms; kitchens. The Mapei Mapelastic Aquadefense Tanking Kit can be applied to: concrete; cementitious screeds and screeds made using special binders (Topcem, Topcem Pronto, Mapecem or Mapecem Pronto); plasterboard (for internal applications only); existing coatings in ceramic, terrazzo and stone; cementitious render; tilebacker boards. The components of the kit are supplied ready to use. Mapelastic AquaDefense is a rapid product: wait 1 hour after applying the first coat and 4 hours after applying the second coat before applying tiles; ceramic tiles may be bonded after 4 hours (at 23°C and 50% R.H. when applied on a dry substrate with less than 3% residual moisture). Mapelastic AquaDefense is elastic: at 23°C it has 3.2 mm crack-bridging capacity without reinforcement. Mapeband PE 120 is made from polyester mesh and PVC fabric: elastic and deformable; impermeable to water and vapour; pre-formed corners and gaskets are available separately. Mapei Mapelastic AquaDefense is a totally solvent-free, ready-to-use, ultra-quick drying, one-component light blue, synthetic resin-based paste in water dispersion. Mapeband PE 120 (PVC waterproof tape) is used to waterproof corners between adjacent walls and between walls and floors to be treated with Mapelastic AquaDefense. Mapei Mapelastic AquaDefense is easy to apply using a long-haired roller, brush or trowel on horizontal, sloping and vertical surfaces. It dries very quickly to form a flexible membrane without a sticky surface. It is resistant to light pedestrian traffic after just 3-4 hours and forms an excellent grip with all types of adhesive for laying ceramic, stone material and mosaic of all kinds. The flexible nature of Mapei Mapelastic AquaDefense helps it withstand normal movements caused by expansion and shrinkage of the substrate due to temperature variations and vibration. Tiles laid on floors waterproofed with Mapei Mapelastic AquaDefense by using C2F-class MAPEI adhesives (such as Mapei Keraquick S1, Ultralite Rapid-Flex S1, etc.) and grouted with Mapei Ultracolor Plus may be opened to pedestrian traffic within 12 hours of starting the work. Mapei Mapelastic AquaDefense is resistant to water, lime-water (ph > 12), and detergents commonly used for cleaning residential environments. Recommendations: Do not apply Mapei Mapelastic AquaDefense if the temperature is lower than 5°C. The product must always be covered with ceramic, mosaic or stone. Do not apply on cementitious substrates or on substrates with residual humidity higher than 3% or recurring rising damp. Do not apply on crumbly cementitious substrates, old floors which are not well bonded to the substrate or surface treatments which impede a good bond. Do not use Mapei Mapelastic AquaDefense to cover cracks. Application: Preparation of the substrate: Substrates must be well-cured, sound, clean, dry and free of oil, grease, cement laitance, paint and any other substance which could compromise the bond. Cementitious substrates must be stable and dry with no rising damp. Surface dust must be completely removed. Uneven surfaces may be prepared using a suitable MAPEI levelling/ smoothing compound. On old ceramic floors with hollowed or empty tile joints, or whenever slopes on surfaces need to be levelled out before spreading on Mapei Mapelastic AquaDefense, we recommend applying a smoothing and levelling layer. Substrates in this condition must be thoroughly checked and all coatings, such as wax, water-repellent treatments, etc. must be removed from the surface with a suitable cleaning product such as one from the Mapei UltraCare range and/ or by abrasion. Before applying Mapei Mapelastic AquaDefense, pay particular attention to expansion joints and fillet joints between horizontal and vertical surfaces. In such cases, apply Mapeband PE 120 bonded in place with Mapei Mapelastic AquaDefense. Before applying the product on old ceramic and natural stone floors, use Mapei Eco Prim Grip Plus primer. Application of the product: Mapei Mapelastic AquaDefense must be applied in two even, coats (approx. 0.4 mm per coat) with a long-haired roller, brush or trowel. Wait until the first coat is dry, making sure the product becomes darker with a matt finish, before applying the second coat diagonally to the first (approximately 1 hour at 23°C and 50% relative humidity of the air and with substrates having residual humidity lower than 3%). The final thickness of the two coats of Mapelastic AquaDefense must be at least 0.8 mm in order to create a robust, flexible and continuous film. Make sure there are no interruptions in the film caused by imperfections in the substrate. If the product is applied to form an anti-fracture membrane on cracked substrates, we recommend inserting Mapetex 50 reinforcement in to the first coat while it is still fresh. Mapetex 50 must be pressed down with a bubble-breaker roller on the first coat of Mapelastic AquaDefense while it is still fresh. Wait until the first coat is dry then apply the second coat in order to completely embed Mapetex 50. Drying times may increase as Mapetex 50 insertion increases the final thickness of the applied film. In bathrooms, a water-tightness test may be carried out 12 hours after applying the final coat. Ceramic, stone and mosaic tiles may be laid 4 hours after applying the second coat (at 23°C and 50% relative humidity of the air) using a C2-class MAPEI adhesive according to EN 12004 standards, to be selected according to the final use of the floor. As an example, for quickly laying tiles use Keraquick S1 (class C2FT S1) or rapid setting products from the Ultralite range. Grout tile joints with a special cementitious grout (such as Ultracolor Plus) or epoxy grout (for example Kerapoxy, Kerapoxy Easy Design or Kerapoxy CQ – class RG). Seal expansion joints with a special MAPEI sealant (such as Mapesil AC or Mapesil LM according to requirements).
