Syntech Poliurea Top Coating: Zaščitna prevleka na osnovi alifatske poliuretanske smole
Syntech Poliurea Top Coating
A protective, pigmented, two-component formulation based on aliphatic polyurethane resins, ideal as a protective and aesthetic coating on waterproofing with SYNTECH POLIUREA SPRAY. Characterised by high levels of elasticity and elevated protection, even in aggressive atmospheres. Available on request in shades from the RAL colour range.
Surface coating pigmented for colouring polyurethane claddings, and their protection from UV rays (which in the absence of the top coating would alter the colour over time). After suitable priming with SYNTECH POLYUREA PRIMER, it can also be applied as a simple coloured aliphatic protective coating.
Polyurea support Vacuum and blow the surfaces to eliminate any dust that may have accumulated in the 24-48 hours following the installation of SYNTECH POLIUREA SPRAY Support in concrete, mortar, brick, tiles The support on which the polyurea 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. It is recommended to use Primer from the SYNTECH POLIUREA PRIMER range. On particularly absorbent substrates, to avoid the formation of craters / blowholes on the surface of the freshly sprayed product, it is recommended to use primers from the SYNTECH POLIUREA PRIMER range, always contacting the Azichem technical staff for clarification on the most suitable type to use. Apply several layers of primer until the porosity is saturated and providing a light dusting with clean and dry quartz sand (0.4-0.7 mm). Never dust off the primer. Provide suitable elastic sealing systems to cover joints, fittings, cracks or fissures subject to significant movements.
Pour component B with component A into a single container, taking care to remove all the material from the packaging. Mix thoroughly with a mixer at low revs, until a lump-free mixture is obtained.
Apply with a roller or brush on the surfaces of SYNTECH POLYUREA SPRAY, within 24-48 hours of spreading the latter.
A thorough sanding of the supports is recommended for any repairs and/or finishes.
From 0.15 to 0.25 kg of SYNTYECH POLIUREA TOP COATING for each square metre of surface to be covered.
