Waterproofing  

Protection against moisture penetration. It is used for waterproofing of damp walls, basement rooms, concrete walls, subwalls and similar facilities where protection against moisture is needed. Not recommended for use at places with permanent hydrostatic water pressure. EN 14891-CM cement water-impermeable product

Substrate has to be hard, dry, free of dust, grease and other impurities. Suitable substrates include substrates made of cement mortar, cement-lime mortar, treated with levelling compounds, concrete just like plasterboards. Cement and cement-lime mortar substrates should dry for at least 1 day for each mm of thickness (T=20°C, rel. humidity 65%), whereas concrete surfaces should dry for at least one month. Application of PODLOGA KONCENTRAT primer is needed (dilution ratio: PODLOGA KONCENTRAT: water=1:3) before the application of material. PODLOGA KVARC is recommended as pre-coating for smooth low-absorption concretes. The primer represents, at the same, time a bridge binding the substrate and the applied material, creating a stronger bond and reducing consumption of material.

Add 5 kg of HIDROFOB per cca- 1.5 l of water, mix thoroughly using an electric mixer and leave to rest for around 5 minutes; then mix again to obtain a pasty compound without lumps. Application is done using a brush and in 3 layers, each time in the direction opposite of the direction of the previous dried layer. The thickness of film after application of 3 layers should be between 3 and 5 cm. At transition points (wall-wall, wall-floor), waterproofing tapes should be used to achieve as good waterproofing results as possible. Breaks in concrete, cracks and other damages should be repaired using appropriate sealing material. (permanently elastic putty and similar) Low temperatures and high humidity may prolong the period of drying.
