Using Screws to hold down the hardiboard and fully secure the 2 layers of subfloor that equals 1 1/2". I'm using 1/4" Hardiboard over an OSB subfloor, then installing 12" porcelain tiles over that. I want this to last so money is no object when coming to preperation. Tensile adhesion after freeze-thaw cycles: ≥ 0.5 N / mm2ġ2 months from manufacture date under storage conditions on wooden pallets in dry environment.I looking for opinions on what is the best brand and type thin set for this application. Tensile adhesion after immersion in lime water: ≥ 0.5 N / mm2 Tensile adhesion after immersion in water: ≥ 0.5 N / mm2 Tensile strength after heat action: ≥ 0.5 N / mm2 Weber.tec superflex D2 is a flexible, fast-curing, bicomponent, based on cement and selected quartz sand containing high reactivity polymers, reactive fillers and additives. The used tools are washed with water immediately after use. Surfaces outside the application area are covered with adhesive tape and protective foil. Do not dilute the material with water or mix it with other building materials. Isolated surfaces will be protected from rain and frost for at least 4 hours after application. When working in strong sun, apply waterproofing in the shade. The setting time is influenced by atmospheric conditions.Īpply the material when the air and underlay temperature is between + 3 ° C to + 30 ° C and avoid bad weather conditions (rain, snow, strong wind, direct exposure to sunlight). Surfaces can be subjected to permanent water action/charging after 3 days. 4 hours after applying the last waterproofing layer. 90 minutes, and the horizontal surfaces, floors, become practical and can be cladded with ceramic tiles after approx. On vertical surfaces, walls, ceramic tiles can be executed after approx. To ensure non-stress drying, the amount per coat should not exceed 1.5 kg / m2. The next layer can be applied when the first layer can no longer be damaged by applying the new layer. The minimum layer must be observed at every point of the waterproofing surface. The first coat of superflex D2 weber.tec is applied to a properly prepared, compact coat over the entire surface (consumption approx. For obtaining a waterproofing layer, it is necessary to apply at least two layers (3 layers for surfaces exposed to water under pressure). The obtained paste can be applied with a wall paint brush or roller, notched trowel or automatized. Pour the fluid into a bucket, add the powdered component, then mix it (2 -3 minute) with an electric mixer (maximum speed of 800 rpm) until a homogeneous paste is obtained, without agglomerations. Cracks and cavities larger than 5 mm must be closed, filled.įlexible weber.tec superflex D2 waterproofing is a two-component material: a fluid-paste component and a powdery one. The edges and corners must be rounded and the protruding parts flattened. Remove waterproofing parts and debris that may reduce adhesion.
#Tec superflex free#
The underlay must be clean, non-deformable, dry, fixed and free of anti-adhering substances (grease, bitumen, tar, dust etc.), frost free, no large cracks or protruding parts. Recommended especially for waterproofing under ceramic tiles.
Also as an adhesive for extruded polystyrene sheets, rigid foam boards and mineral fiber tiles.
As preliminary waterproofing and bonding layer under polymer modified bituminous layer, waterproofing continues under masonry, bonding layer on old surfaces of anionic bitumen. For waterproofing water tanks (inside, up to 15 m water column). Also for subsequent waterproofing of the interior basement walls. For flexible external waterproofing of basement walls from masonry or concrete, below ground level, concrete floors or foundations.
