PAINTOP ANTIALGA WASHABLE QUARTZ EMULSION PAINT ANTI-MOULD ANTI-ALGAE series 638 DESCRIPTION PAINTOP ANTIALGA is an external wall emulsion based on acrylic resins and silica components, highly effective in covering and masking imperfections in the support. The acrylic resin component provides the product with high washability and resistance to the alkaline environment typical of cement supports and mortars in general. Thanks to its special formulation - enriched with anti-mould and anti-algae additives - preserves treated surfaces against the formation of mould, algae and moss. Surfaces painted with PAINTOP ANTIALGA assume an opaque aesthetic aspect. INSTRUCTIONS FOR USE May be applied on: - New and old plasters based on hydraulic binders. - Concrete surfaces. - Old paints and wall coatings that are organic or mineral in nature, dry, compact, absorbent and cohesive. - Mineral conglomerates of various kinds, as long as they are absorbent. Surfaces should be adequately prepared by following the instructions given in the paragraph 'PREPARING THE SURFACE’. Do not apply on freshly painted surfaces. TECHNICAL SPECIFICATIONS - Ensure that the surface has matured for at least 28 days. - Check the state of maintenance. The surface must be solid. Otherwise reface or consolidate with specific products. - Remove, brushing or washing, encrustation. - Where painted, removed flaked and non-adherent areas, thick layers of whitewash and/or distemper must be totally removed wetting the surface abundantly or using a water jet cleaner. - Smooth out irregular surfaces. Holes, flaking, cracks and dips should be filled with TAMSTUCCO 9400006 or TAMSTUCCO POWDER 9410110; on external walls using netting and BETOMARC 9450150 or RASAMIX 9440160 or other cement based products. - Cracks, indoors and out, should be suitably widened and filled with putty or similar. - Smooth putty and filler with emery paper. - Remove deposits of dust, smog and similar, by brushing. - In the presence of mildew, treat the surface first with COMBAT 222 Detergent 4810222 and COMBAT 333 Protection 4810333. - Ensure that the support is fully dry and apply: Indoors a coat of IDROFIS 4700006 acrylic mural fixative diluted at 1:6 to 1:8 with water. On outside surfaces or indoor surfaces with old distemper or powdery surfaces, apply a coat of ISOMARC 4410111 solvent mural fixative diluted at 40-100% with synthetic 5210011 thinner. - Proceed with application of PAINTOP ANTIALGA as described in the application instructions. - Type of Binder: acrylic copolymer in aqueous emulsion - Classification per UNI EN 1062-1: (paints for exterior) .Gloss per EN ISO 2813: class G3 (<10 matt) .Dry film thickness per ISO 3233: class E3 (100-200 μm) .Grain size per EN ISO 787-18: class S2 (<300 μm medium) .Water vapour transmission rate per UNI EN ISO 7783-2: class V3 (Sd>1,4 m low) .Liquid water permeability per UNI EN 1062-3: class W2 (0.1-0.5 medium) .Crack-bridging per UNI EN 1062-7A: class A0 (no requirement) .CO2 permeability per UNI EN 1062-6: class C0 (no requirement) Other characteristics - Specific gravity per UNI EN ISO 2811-1: 1,67±0,05 kg/l - Viscosity per UNI 8902: 52000 ± 4000 cps at 25 °C (Brookfield viscometer) - Maximum quartz granulometry: 100 μm - Wet-scrub resistance per UNI 10560: >5000 cycles, excellent - Alkali resistance per UNI 10795: alkaliproof - Mould and algae resistant per UNI EN 15457 and UNI EN 15458 - Drying time (at 25 °C and 65% R.H.): to touch in 30 min; to recoat after 4 hours. Reinforced concrete surfaces: - Brush the surfaces and eliminate eventual coats of old or flaking paint. - Remove the poorly adherent structural parts in cement. - Metallic terminations of reinforcements touching the surface, after cleaning and removal of rust present, must be treated with BETOXAN PRIMER 9490125 rust-proofing. - Renovate the missing parts with BETOXAN 400 9490140 thixotropic non shrink fibre reinforced Plaster and/or BETOXAN 200 9490120 non shrink anti-carbonating plaster. - In the presence of mildew, treat the surface first with COMBAT 222 Detergent 4810222 and COMBAT 333 Protection 4810333. If necessary add COMBAT 111 4810111 to the emulsion in the ration of 1 litre o additive to 7 litres of product. - Ensure that the support is fully dry and apply: Indoors a coat of IDROFIS 4700006 acrylic mural fixative diluted at 1:6 to 1:8 with water. On outside surfaces or indoor surfaces with old distemper or powdery surfaces, apply a coat of ISOMARC 4410111 solvent mural fixative diluted at 40-100% with synthetic 5210011 thinner. - Proceed with application of PAINTOP ANTIALGA as described in the application instructions. *(The dilution of the insulator and the quantity to be applied depend on the absorption of the support and should be determined by preliminary test on the specific support) PREPARING THE SURFACE APPLICATION INSTRUCTIONS Plastered surfaces: San Marco Group Spa - Via Alta 10 - 30020 Marcon (VE) - Tel +39 041 4569322 - www.san-marco.com - [email protected] - [email protected]
