with excellent durability, anti-fungal, anti-algal and alkali resistance. Berger 303 will provide years of beauty and protection on exterior and interior surfaces. Formulated with green raw materials
resulting in an environmentally friendly premium coating. Berger 303 Flat is self-priming on concrete walls, seals hairline cracks and hides minor surface imperfections.
SURFACE PREPARATION (The performance of this coating is directly related to the degree of surface preparation)
CONCRETE, PLASTER, MASONRY
New Surfaces: Smooth new surfaces, removing any loose sand & mortar splashes manually or mechanically. Allow surface to weather for a minimum of 14 days then prime the substrate with one coat of
Berger Alkali Sealer. If surface is rough or uneven use one or two coats of Berger Unoshield followed by one coat of Berger Alkali Sealer, for external surfaces only. Apply two coats of Berger 303 Flat Emulsion.
For porperties by coastal ares apply one coat of Berger Alkali Sealer or Berger Luxatex on new concrete surfaces. Berger ALD Primer, Berger Contractor Primer or Berger Grip Seal can be used if the surface has been weathered for at least 30 days.
Note: These are estimated curing times before coating the concrete. If the concrete mixture is excessively alkaline and/or the weather results in a mainly damp external surface, an additional two weeks should be allowed before coating the substrate with Berger Alkali Sealer.
Previously Painted Surfaces: Ensure surface is clean, dry and free of dust, grease, algae, dirt and contaminants. Treat fungal or algal growth by first power washing the substrate then scrubbing with Berger Biocidal Solution. Rinse thoroughly with clean water and allow to dry thoroughly to a moisture content of < 10%. Apply another coat of Berger Biocidal Solution, which must be top coated within the same day and before it is affected by rain, with Berger 303 Flat Emulsion. Surfaces showing cracking, peeling, chalking or efflorescence should be wire brushed, scraped and sanded to remove loose flaking material and reduce previous film to a flat finish. Thoroughly dust down the entire surface then apply one coat of Berger Alkali Sealer or Berger Penetrating Liquid followed by two coats of Berger 303 Flat Emulsion.
WOOD
New Surfaces: Sand new surfaces to a smooth finish. Use Berger Sanding Sealer prior to application of Berger Wood Primer Undercoat or Berger Grip & Seal. Allow the recommended time for drying. Apply two coats of Berger 303 Flat Emulsion.
Previously Painted Surfaces: Ensure that dirt, stains, loose material and contaminants are removed. If the surface is cracking or peeling, remove the loose material by scraping. Thoroughly dust to ensure a clean surface. Treat any fungal growth with Berger Biocidal Solution. Apply one coat of Berger Wood Primer Undercoat or Berger Alkali Sealer. Allow to dry for the recommended period then apply two coats of Berger 303 Flat Emulsion.
GYPSUM
Sand to a smooth finish and remove all dust. Apply one coat of Berger Unoshield. For interior substrates prime with Berger Gypsum Primer. Allow recommended time for drying, then apply two coats of Berger 303 Flat Emulsion.
METAL SURFACES.
Iron & steel should be thoroughly cleaned to remove all oil, grease, rust, scale and moisture. Prime metal with a suitable Berger Metal Primer, such as Berger Grip & Seal or Berger Zinc Chromate Primer then apply two coats of Berger 303 Flat Emulsion. Aluminum & Zinc should be degreased and etched with Berger Self Etch Primer followed by one coat of Berger Metal Primer. Allow to dry and apply two coats of Berger 303 Flat Emulsion.
