Kimicover DUO

It meets the requirements defined in EN 14891 and is CE marked according to EN 1504-2, it is used for the principles of use PI (protection against entrance through coating), MC (protection against humidity through coating) and IR (increase of resistivity).

The substrates must be clean and mechanically consistent, any holes or irregularities in the substrate must be previously repaired with suitable Kimia products. In case of waterproofing of already tiled surfaces, remove the first row of wall tiles for a height of about 20 cm, perform an acid washing of the surface with Soluzione P. In case of degraded concrete substrates it will be necessary to check the depth of the degradation and proceed with a proper cortical restoration cycle. Between 8 and 24 hours prior to the start of operations, the screeds must be treated with a coat of Kimicover FIX MV primer. The points of contact between the screed and the collection wells, once the tiles have been removed, the external edges of the joints have been cleaned and possibly rebuilt, will be waterproofed by applying Kimicover JOINT P and Kimicover DUO reinforced with Kimitech 120 mesh. The joints between the wall and the floor will be waterproofed by applying Kimicover JOINT and Kimicover DUO reinforced with Kimitech 120 mesh. The joints will be waterproofed by laying Ethafoam, sealed with Tecnoseal 130 or Tecnoseal 88 (which must cure at least 24 hours) before laying Kimicover JOINT elastic strip. The distance between the joints must be evaluated on a case-by-case basis, depending on the type of substrate and the expected stresses. Pour the liquid (component B) into a suitable clean container and slowly add the powder (component A), according to one of the two selected ratios, taking care to mix it slowly and carefully with a mechanical stirrer for a few minute until you get a homogeneous mixture absolutely free of lumps or dust particles not dispersed both in the bottom and in the walls of the container. Apply a first coat of Kimicover DUO reinforced with Kimitech 350 mesh. Once hardened and in any case not before 24 hours, apply a further coat of Kimicover DUO. When laying the product do not exceed 2 mm per coat and do not make overall thicknesses greater than 4 mm. After a minimum of 7 days bond the cermic tiles, using Aderflex KR powder adhesive for tiles. Any expansion joints on the substrate will be respected in the covering, which will then be sealed with Tecnoseal 88 or Tecnoseal 130 sealant
