Colorit - Hidrofob Elastic 1K

Characteristics

Exceptional water-repellency. Good elasticity. Excellent adhesion.
Used for waterproofing of balconies, bathrooms, technical water reservoirs and similar, before their coating with ceramics. Hidrofob elastic 1K is water impermeable with positive and negative water pressure of up to 1.5 bars. It is designed for indoor and outdoor use, before laying of ceramics in combination with Hibrofob elastic tape. EN 14 891 CM 01 cement water-impermeable product with improved crack-bridging at low temperature (-5°C).

Substrate Preparation

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. 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 primers represent, at the same time, a bridge binding the substrate and the applied material, creating a stronger bond and reducing consumption of material.

Application

Add 20 kg of HIDROFOB ELASTIC 1K per cca. 5.2 l of water and mix thoroughly using an electric mixer until a homogeneous compound is obtained free of lumps. The working time of the mixed compound is cca. 1 hour.

Waterproofing under ceramic or stone coverings

To achieve full waterproofness of the targeted surface, mixed material should be applied in at least two, and if necessary, in three layers. The thickness of each layer 1-2 mm on the entire surface, with the total thickness not exceeding 5 mm. Each coating is applied on the previous hardened layer (drying 5-6 hours). The first layer is applied using a brush, with glass mesh (160 gr) pressed into the material while it is still wet, with overlapping (min. 10 cm) at joints. The second layer is applied transversally to the hardened coating. Make sure that full surface coverage is obtained with each layer. At critical points (corners, wall joints, floor joints and similar) use appropriate tapes (Hidrofob Elastic Tape and Hidrofob Elastic Tape Plus) just like auxiliary elements (Hidrofob Internal Angle, Hidrofob External Angle and Collars). Breaks in concrete, cracks and other damages should be repaired using appropriate sealing material (permanently elastic putty and similar).

Negative Pressure Waterproofing

For full surface waterproofing, at least two, and if necessary, three layers of previously mixed compound need to be applied, evenly on the entire surface. The thickness of each layer is 1-2 mm. The first layer is applied using a brush, with glass mesh (160 gr) pressed into the material while it is still wet, with overlapping (min. 10 cm) at joints. The second layer is applied transversally to the hardened coating.

Positive Pressure Waterproofing

In this case, at least three waterproofing layers need to be applied, with reinforcement done in the second layer. Overlapping of at least 10cm is obligatory at mesh joints. Each layer is applied on previously hardened layer. Thickness of each layer 1-2 mm (max. thickness of all three layers 5 mm)
