K11 family of highly flexible waterproof coating

Products Division K11 highly flexible waterproof coating is a two component, acrylic polymer-modified cement-based waterproof system. Powder mixed with the additives, the occurrence of a chemical reaction to form a tough elastic waterproof membrane, the membrane for concrete and mortar have good adhesion, can with a tight combination of a strong permanent crystal, preventing the infiltration of water . Technical indicators (performance standards: GB / T23445-2009): Standard test items test results for individual judgment Solid content% ≥ 70 73 qualified drying time (h) dry time ≤ 4 3.2 Eligible drying time ≤ 8 5.6 qualified Tensile strength Mpa ≥2.0 2.2 Qualified elongation at break (no treatment)% ≥80 110 qualified impermeability (0.3Mpa, 30min) impervious meet the eligibility wet base surface adhesion strength / Mpa, ≥ 1.0 1.50 Qualified Scope 1. Indoor and outdoor structures, precast structures, brick and other water; 2. Underground car parks, tunnels, drainage and water supply pipes, floor wall floor roof, swimming pool, water tanks and other water; 3. May appear slight vibration, displacement, building structure cracks surrounding the nozzle, back strip interfaces, etc. waterproof seams or joints. Features Benefits 1. Flexible, able to adapt to a certain degree of shock structures and displacement. 2. Good adhesion, and is able to loose substrates, shaped parts and precast seams closed. 3. Energy construction in the wet base surface. 4. Directly in the waterproof membrane of cement plastering, paste stone, tiles and so on. 5. At the same time excellent waterproof, waterproof membrane with good ventilation function. 6. Environmentally friendly products, can be used for drinking water pool. Construction technology base surface treatment: base surface must be solid, clean, smooth, moist no oil, no floating dust; base defective pores, cracks, pre-patched with cement mortar leveling; Yin and Yang Xiu half rounded corners with a spatula. Ingredients: According to the mixing ratio of the additive into the container, then slowly pour the powder additives, and stir until no lumps, uniform glue-like, then you can use the stand for 5 minutes; in the course of Make sure to keep intermittent stirring to prevent stratification precipitation. Mixing ratio: liquid material (additive): powder = 1: 1.2 to 1.6 (weight ratio) node processing: the node positions splash wet base surface treatment, for yin and yang corner, wall pipe, floor drain port, construction joints and other polymers used cement-based waterproof coating and fiberglass cloth to enhance the process, a thickness of about 1.0mm. Construction: Using a stiff brush, roller or spraying machine mixed slurry evenly brushing or spraying on damp substrates; if for proof, just brushing a layer; a waterproof, need brushing two to three. When the first layer to dry to just tack (usually takes 1 to 2 hours), then brushing the second layer, brushing every two perpendicular directions should be. Coating protection: After the construction is completed the slurry, the coating must not completely pre dryness necessary protection, including the prohibition of pedestrians, rain erosion, exposure, injury and other sharp objects; completely dried after coating does not need to do anything special The protective layer. Conservation coating: Coating 24 hours after completion of the construction proposal covered with a wet cloth or spray coating the coating conservation watering, usually 2 to 3 days; air humidity, poorly ventilated place to dry time will be longer, whereas shorter air circulation particularly poor environment for the progress of the project can be mechanical ventilation method to accelerate the speed of dryness. Waterproof protective layer: waterproof layer after dryness can make 1.5 2.0cm thick protective layer of cement mortar to on demand. Construction temperature: suitable for use in the environment of 5 ℃ ~ 35 ℃. Reference to the amount waterproof membrane thickness is 1mm, the theoretical amount of about 1.5 ~ 2.0kg / m2 (refers to the total amount of powder and liquid) the actual amount depending on the specific base surface and loss situation. Flat base surface Dosage: 1. For moisture, brushing a layer thickness of about 0.6mm, according to a flat base surface depending on the situation, about 1 kg / m2; 2. Used for waterproofing, brushing story, thickness 1.2mm, according to flat base surface depending on the situation, about 2 kg / m2. After the quality inspection and engineering waterproof layer construction is completed, should carefully examine each part of the whole project, especially the weak link, identify problems and timely repair, the coating should not have cracks, Alice, bubbling, delamination and so on. Once water testing shall be completely dried coating can be carried out, under normal circumstances require more than 48h, in a particularly humid airless environment may take longer. After the toilet and bathroom waterproof finish, water 24h no leakage in compliance. After the roofing done, you should check the drainage system is smooth, leaks (which can be sustained in the rain or after watering 2h conduct, conditional water roof water available 24h check). Note * Construction temperature should be 5 ℃ to 35 ℃; * within one hour paste exhausted after the opening tune; * first base surface wetting with water after the construction, but the base surface can not have water; * in cement calendering the base surface before construction, you must first re-galling base; * When using, do not be incorporated in the product water or other material; * liquid component storage temperature not lower than 0 ℃; * Before construction, please read carefully Application Instructions; please use the appropriate protective measures, such as gloves * When construction. Packaging and storage and transport packaging: 42 kilos: (25kg + 17kg powder additive) / cover 20 kilos: (12kg + 8kg powder additive) / set 10kg: (6kg powder + 4kg additive) / set appearance : [liquid material: white] [Powder: gray] store in a cool dry place, unopened product, shelf life of 12 months. Transportation: The product according to non-dangerous goods transport product quality to ensure that this product meets the application specifications, reliable and stable quality and assume responsibility for defective products, the note is being prepared in accordance with the practice of many other research data, user-friendly, the company does not assume the actual construction environment can not meet the construction requirements, thus triggering the loss and liability. Before construction proposal read the instructions carefully and in accordance with the requirements of the construction, use of the process in case of doubt, please consult Guangzhou Building Materials Technology Co., Ltd. Accor.
