Fields of application
Syntech Primer EP-S is used as an adhesion promoter on porous substrates in concrete, stones, etc. for: epoxy, polyurethane and methacrylic paint cycles; epoxy, polyurethane and methacrylic flooring; surface consolidation of porous supports; consolidation and waterproofing of external flooring; dustproof treatment.
Allowed supports
Concrete
Wood
Natural stones
Preparation of supports
The support on which the epoxy, polyurethane or methacrylic 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 expansion, 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 <= 4%. 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 or grouted with Syntech AS 21. In the event of the presence (even suspected) of humidity deriving from capillary rising from the substrate, it is recommended to apply the Syntech Pavidamp epoxy resin for "wet bottoms" beforehand. 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 the components each in their own container before mixing. Pour component B into component A and mix for 3 ÷ 5 minutes with a drill and disperser at low speed. Avoid taking partial quantities from the packaging to avoid any errors in the ratio that would cause incorrect hardening.
Syntech Primer EP-S can be applied by brush or roller. On particularly absorbent surfaces, apply Syntech Primer EP-S in 2 coats.
