Three-component anti-humidity epoxy base, in aqueous emulsion

A three-component formulation, with a fluid epoxy resin base in aqueous emulsion (A + B) to be mixed with the third component (C) consisting of white cement and micro-quartz, specially designed to be used as a primer for cementitious surfaces in the presence of humidity and in conditions of hydraulic counter-thrust. Generally referred to as โ€œwet-bondingโ€, it is particularly suitable as an anti-humidity barrier for the subsequent laying of parquet.

    Fields of application
    Building connection layers and smoothing cement surfaces; bottom layers for resinous coatings of floorings in the presence of damp subbases; anti-humidity barriers in concrete, brick and stone masonry; surfacings of porosity, cracks and superficial irregularities. As protection from rising damp for bases where operations with polyurea resins SYNTECH POLYUREA will be carried out.

    Preparation of supports
    The support on which the resin system is to be laid must be suitable for withstanding the stresses resulting from the intended use, such as static or dynamic loads, impacts, thermo-hygrometric dilatations, vibrations, etc. As regards the characteristics of the substrate (maximum humidity, cohesion, strength class, flatness, etc.) and the preparation of the surface that will accommodate the resin system, we recommend the requirements set out in chapter 5 of the UNI 10966 standard ("RESIN SYSTEMS FOR SURFACES HORIZONTAL AND VERTICAL - INSTRUCTIONS FOR DESIGN AND APPLICATION "). In any case, carefully clean and degrease the surfaces, removing any kind of dirt, paint residues or incoherent parts. Evaluate the most convenient type of mechanical preparation (shot peening, sandblasting, hydro-washing, etc.). The surfaces must also be free from discontinuity, and possibly leveled and regularized with products from the FLOOR line or the REPAR line. Apply by roller, brush or spray from 150 to 200 g / m2 of Syntech Primer EP-W to consolidate the substrate and facilitate the adhesion of the subsequent coating. Tiled floors, or floors covered with pre-existing resin, must be subjected to mechanical roughening carried out with shot blasting, milling, bush hammering, etc., until the total elimination of the waterproof crust and the opacification of the surfaces. Remove dust after abrasion.
    Mode of use
    Prepare the mixture of the 2 liquid components (A+B), pouring the contents of the component B in the container of the component A. Mix with drill for about 2 minutes. Add the pre-dosed hydraulic binder (high resistance white cement) to the mixture A+B, and mix with a mixer drill. To disperse the product optimally, pour the powders (component C) a little at a time, continuing to stir with drill, until a homogeneous lump-free mixture is obtained.

    If it is used as a base: dilute with 10-15% by weight of clean, soft water and apply with a roller or brush. Indicative consumption: 0.4-0.5 kg/mยฒ on regular supports, 0.7-0.9 kg/mยฒ on irregular supports.

    If it is used for fine finishing coats: load the system A+B+C diluted with 10-15% of fresh clean water, with 60-70% spheroidal quartz (0.04-0.25 mm). Apply with steel trowel or plastering trowel. Indicative consumption: 1-2 kg/mยฒ.

    If it is used for medium finishing coats: load the system A+B+C diluted with 10-15% of fresh clean water, with 70-80% spheroidal quartz (0.1-0.5 mm). Apply with steel trowel or plastering trowel. Indicative consumption: 3-4 kg/mยฒ.
