Kimitech ECF
Three-component thixotropic epoxy-cement system for resin-flooring and caoting
Kimitech ECF is a three-component epoxy-cement system consisting of the two-component epoxy resin Kimitech EC (part A + part B) and a dry mix of hydraulic binders and additives (Kimifill K12), with a trowelable plastic consistency, optimized for mechanized application. It can also be pigmented on site to guarantee different aesthetic finishes (spatulated, cloudy effects etc.).
Applications
Kimitech ECF is used for spray waterproofing of walls against the ground. • It is used, after priming with Kimicover FIX MV, to regularize (in terms of absorption and flatness) tiled substrates on which to apply Kimifloor decorative cycles. • it is used to create cycles, even decorative ones, with a more or less material appearance and in view of the realization of the pore-dye skimming preparatory to the self-leveling systems.
Certifications
Kimitech ECF è marcato CE come rivestimento protettivo secondo la EN 1504-2 (principi di intervento MC e IR) ed è marcato CE come massetto a base di resina sintetica classe SR-B2,0-AR0,5-IR14,7 secondo la EN 13813.
Application
In case of counter-thrust structures to be waterproofed and plastered or tiled, Kimitech ECF can be applied directly on the surface (as long as there are no water leaks) manually or mechanically (airless pump). Roughen the last fresh coat of Kimitech ECF by freshly dusting of Kimifill MP. After its complete hardening (7 days), use the adhesion promoter Kimitech EP-RG; to lay ceramic tiles, use Aderflex RP adhesive mixed with Kimitech ELASTOFIX. Particular attention must be paid to the preparation of the substrates in case of resin floors and coatings. Existing coatings must be checked, cleaned and mechanically prepared until a solid and adherent substrate is reached. In case of bad adhesion to the substrate, they must be removed. Any holes or irregularities in the substrate must be previously repaired with suitable Kimia products. On tiled floors, perform a proper shot peening and water cleaning (any excess water following the operation must be removed with a liquid vacuum). Properly cured concrete substrates must be structurally sound (the pull-off tensile strength of the concrete must be> 1.5 MPa). Any part that is detached and does not have sufficient mechanical characteristics must be removed. To eliminate dust deposits, pre-existing coatings, traces of grease, rust, release agents, paints and varnishes, cement mortars and any other substance or material that could affect the adhesion of coatings, carefully prepare the substrate by shot peening, milling, bush hammering, staking. Then carry out a high pressure cleaner. To prepare the mixture, pour component "B" (hardener) into component "A" (resin) of Kimitech EC and mix with a low speed drill (200-300 per minute) until you get a perfect mixture, having care not to incorporate air during mixing. Add the Kimifill K12 and continue stirring until you get a homogeneous mixture. For valuable aesthetic effects, the mixture can be added with pigments, oxides, glitters or neutral water-based coloring pastes. Apply the product on substrates previously primed with Kimicover FIX by placing the Kimitech 350 reinforcing mesh between the two coats in case of application on tiled substrates.
