PRIMER EP

Two-component waterproofing and consolidating primer, in solvent solution, for screeds and industrial flooring. Where to use: - Primer for the consolidation of surfaces of dusty or crumbly cementitious screeds, for anhydrite screeds, radiant heated screeds, old terrazzo tiles, gypsum and gypsum board. - Waterproofing damp screeds to isolate residual moisture. - Anti-dust impregnating primer over industrial flooring, garages, raised flooring. If a levelling compound is used after the application of Primer EP, spread dry sand over the just treated surface to create a suitable mechanical key. The substrate must be dry and clean, free of oil, grease, traces of paint and any loose particles. Technical data: Minimum drying time: 24 hours depending on the porosity of the substrate. Consistency: liquid. Colour: transparent. Flammability: yes. Application temperature range: from 10°C to 40°C. Pot life of the mixture: 4-5 hours. Mixing ratio: Part A : Part B = 1 : 1. Storage: 24 months. Application: by roller, brush or watering can. Consumption 0.5-0.7 kg/m2. Packaging 5 5 kg drums.
