Tanking kit

The tanking kit is a ready-mixed, under-tile tanking system to protect water sensitive substrates from exposure to water. Suitable for wet areas such as bathrooms, showers in residential buildings, hotels, old people's homes and hospitals. Should not be used in places exposed to pressurised water, for an instance swimming pools. Ready to use, no mixing required and easy to apply with a roller. The kit includes a high performance joint reinforcing tape to protect against movement in floor joins and corners etc. The contents are all INSIDE the bucket and the contents are protected in the bucket with polystyrene infill's to stop transit damage.The instructions are printed on the rear of the tanking kit.

For anti-moisture insulation systems in wet rooms and rooms intended for human residence. The tanking liquid is a ready-to-use singlecomponent, solvent-free sealant composed of polymer dispersion, fillers and modifying additives. When applied to the surface, upon binding it creates a flexible and water-insulating layer.

Tanking kit contains:
  • 4kg Tanking Liquid
  • 1l Primer
  • 10 Metres flexible Sealing Tape
  • 2 Flexible Pipe Collars
  • 2 Corners
Features:
  • Consumption to 1,2kg/m²
  • Solvent free
  • Drying time: 2h
Tanking liquid and primer
Tanking liquid
Tanking liquid

The tanking liquid is a ready to use, single component, solvent-free sealant mass, consisting of polymer dispersion, fillers and additives. When applied to a substrate and cured, it forms a flexible waterproofing coating. The product is intended for use inside places intended for human residence, especially in humid areas (such as bathrooms, kitchens, laundries), to perform insulation against moisture under linings and coverings, such as ceramic tiles, glazed tiles, terracotta, wooden floors and panels, and synthetic carpets.

The product is intended for priming absorbent and porous surfaces, inside and outside buildings. It is especially recommended for cement - limestone plaster, gas concrete, plaster-carton boards and cement plaster. The primer has a high penetration ability, is deeply absorbed into the substrate, thus strengthening it, while allowing for „breathing”. These benefits improve the structure of the substrates, which, due to the passage of time, have lost their appropriate parameters. The priming solution improves adhesion to the surface of other materials that will be used on the primed substrate. By reducing the absorbency of the substrate, the wear of the applied coating materials, emulsion paints, glues, mineral putties reduces as well. The solution, due to the content of the biocide and fungicide, protects the primed substrate against the formation of mold and bacteria in the product.
