  • Process for the preparation of a water-impervious surface coating
    Patent number: 4597817
    Abstract: A process for the preparation of a water-impervious surface coating on a substrate comprising applying to the substrate a layer of an aqueous bitumen emulsion containing, based on dry matter, 5-55% by weight of an acrylic prepolymer, 1-15% by weight of an air-drying alkyd resin, 40-80% by weight of bitumen, and optionally up to 5% by weight of additives, applying to this layer a glass fibre layer, and subsequently applying to the glass fibre layer at least one layer of water-based paint.A considerable saving in labor and time is obtained by the process and the coating obtained has an increased water vapor diffusion resistance.
