Betonfix 300

Betonfix 300 is CE marked as protective coating according to the 1504-2, MC and IR intervention principles.

Before applying make all the preliminary steps for a correct application of the product. • In the case of waterproofing from the inside of underground walls, wells and structures subjected to negative hydraulic pressures in general, proceed to the creation of channels and systems for the collection and evacuation of water . • In the presence of concentrated water leakage, pick out the point of seepage, clean around it and apply hydraulic mortar Betonfix WW . If there are diffused seepages on the surface, apply Betonfix WW directly on the surface to allow the product to knead with the exudation of water and then block the porosity. Particular attention should be paid to the preparation of substrates: • The existing coatings must be controlled, clean (for installation on tiled floors with Soluzione P) and mechanically prepared to reach a sound and adherent ground. In case of poor adhesion to the substrate, coatings must be removed. Any holes or irregularities of the substrate must first be repaired with suitable Kimia products. • In the case of degraded substrate check the depth of degradation and repair through cortical repair cycle. • The concrete castings, properly completed, must be structurally sound (the tensile “pull off” strength of concrete must be >1.5 MPa). Remove each detached part or every part having poor mechanical properties. Remove dust, existing coatings, grease, rust, release agents, paint, cement laitance and any other substance or material which may affect the adhesion of coatings by sandblasting, high pressure, washing or brushing. Deep and extensive irregularities (gravel nests, leaks between castings etc.) must first be resolved. • The connections between wall and floor, in the case of waterproofing interventions in the presence of negative hydraulic pressure, will be treated by means of connecting gutters. • If there are joints, opt for a proper renovation cycle and waterproofing. • Any critical contact points between screed and collection wells, before being sealed, will be subject to removal of the tiles, cleaning and eventual reconstruction of the outer edges of the connecting joints. Add the water to each pack (25 kg) of Betonfix 300. To increase flexibility and to get a trowable two-component system, Betonfix 300 can be mixed with Kimitech ELASTOFIX. Saturate with water the area to be treated, taking care to eliminate, at the time of casting, any pools of water. Stir the product for about 5 minutes with a cement mixer or, in case of small quantities, with drill and whisk. Add 3/4 of the water or latex and then, gradually, the product until you get the right consistency. Once obtained a homogeneous mixture free of lumps, make it rest for 10 minutes and then apply with a brush, spatula or spray with an airless pump. In case of deformable structures, reinforce the coat using Kimitech 350 glassfiber net.
