SYNTECH POLIUREA PRIMER – EPOXY

Two-component epoxy primer for cementitious surfaces, marble and wood

Code: SYN.0309

Components: 2

Appearance: Liquid + Thick liquid

SYNTECH POLIUREA PRIMER - EPOXY is a two-component primer based on modified epoxy resins and special hardeners, solvent-free. Specially formulated to provide the right compromise between impregnation and wettability of the support to which, once applied, it forms a well-bonded layer.

Consumption

From 350 to 700 g for each square metre, based on the intervention carried out on the support (bush-hammering, shot peening, etc.), the porosity of the support itself and the incorporation or not of quartz sand in the particle size and quantity proportionate to the intervention to be implemented.

Use fields

Adhesion promoter for epoxy, polyurethane and polureic coatings, adhesion promoter for porous and deteriorated substrates, consolidating agent for cement and concrete.

Preparation of supports

The support on which the polyurea or resinous system must be laid must be suitable for withstanding the stresses resulting from the intended use, such as static or dynamic loads, impacts, thermo-hygrometric dilations, 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. 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.

Use method

Carefully mix component A to allow the correct homogenization of the fillers present; then combine it with component B in a suitable and large container. Then mix the compound with a mechanical stirrer at low speed until a homogeneous mixture is obtained.
When the support is ready, apply SYNTECH POLIUREA PRIMER - EPOXY using rollers, brushes or spatulas trying to obtain a dry film.
