Fields of application
For protective and decorative painting of concrete floors, reviving the colour of old resin flooring, wall plinth enamelling, and so on. Perfect for mechanical workshops, manufacturing industries, warehouses and factories generally in which special and high chemical and mechanical resistance are required.

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. The humidity of the support must be <= 3%. 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. Apply Syntech Pavicrom when the primer is completely dry and no later than 24 hours from the end of its application. In case of presence (even suspected) of humidity deriving from capillary rising from the substrate, it is recommended to apply in advance the epoxy resin for "wet substrates" Syntech Pavidamp. 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
Mix component A and component B separately, directly in their packages, in advance. When applying, combine the two components into a single container and thoroughly mix for 2 minutes using appropriate equipment (trolling motor). To prevent any errors in the mixing ratio that would result in a lack of or incomplete hardening, do not extract partial quantities from the packaging. Next, pour component B into the container of component A.
Syntech Pavicrom is applied with a “short-pile” roller within 24 hours after applying the primer. Add the dilution water: the first coat diluted with water at a rate of 10 ÷ 20% depending on the porosity, cohesion of the support and the temperature; the second finish must be diluted by 6 ÷ 11%. After adding the dilution water, continue mixing for a few minute.
We recommend applying two overlapping coats of the product, at temperatures not lower than +5° C. The second coat must be applied within 24 hours. 3-5% by weight of quartz B0 or B1 (or hollow glass microspheres) can also be added to achieve a non-slip effect.
