Application of wergu K11 polymer waterproof slurry

2022-07-22
  • Detail

Construction: weiergu K11 polymer waterproof slurry is a material that does not work with water. If there is continuous leakage on the base surface, it should be grouted to stop the leakage before construction. If the old kitchen and bathroom are waterproof and repaired, the original organic coating should be completely removed or a layer of cement mortar should be splashed on it, and the construction can be carried out after it is dry

the construction base surface shall be firm, flat, free of sand and hollowing. In addition, use 1:2.5 cement mortar to add an appropriate amount of K11 additive to all internal corners and nozzle positions to form a mortar, and swing it into a circular arc shape. Before waterproof construction, clean up the construction parts, fully wet the base surface with clean water, and keep the base surface wet during construction, but there shall be no ponding

K11 super flexible waterproof slurry should be selected for local waterproof reinforcement treatment for any parts that may cause small vibration, such as expansion joints, structural joints, the periphery of the joint between pipes and concrete

first, pour K11 waterproof slurry additive into the container, then slowly pour the powder into the liquid, fully stir with an electric mixing drill until there is no particle and sediment, and then mix slightly after standing for 5 minutes. Intermittent mixing shall be maintained during construction to prevent the mixed mortar from settling

use a brush or roller to directly coat the mixed slurry on the base surface. Multi layer construction method should be adopted. The one-time brushing should not exceed 0.8mm, and the total thickness should not exceed 2mm. The coating shall be uniform without local deposition, especially in the untreated internal and external corners. Brush repeatedly with a brush as much as possible to avoid excessive slurry deposition in these parts

after the first painting, the second layer shall be painted after the initial drying, and the painting directions between the two layers shall be staggered. After coating each layer, carefully check whether there are missed coating and sand holes, and timely fill them

in the construction process, in order to facilitate the later process of pasting ceramic tiles, after the last coat of waterproof layer is coated, after the coating is dry and qualified, wet the waterproof layer, and then paste ceramic tiles with 1:2.5 cement mortar. If necessary, add an appropriate amount of cement mortar additives or common glue in the market into the cement mortar. Pay attention not to paste tiles directly with cement mortar, so as to avoid excessive shrinkage of cement mortar layer during drying, resulting in hollowing, falling off and other phenomena

in order to ensure the film-forming reaction of polymer in the waterproof layer, the water test is generally carried out 7 days after the construction of the waterproof layer. For large high-grade decorative tiles, it is recommended to choose weiergu impermeable adhesive plaster for pasting, and then use weiergu color tile sealant for caulking
