Abstract:
1. A method of painting a substrate with an emulsion paint comprising spherical polymer particles, comprising the steps of: applying an opaque first coating in at least one opaque layer, said first coating being a water-borne emulsion of a styrene acrylic copolymer; and applying said emulsion paint comprising spherical polymer particles in at least one semi-opaque-layer over the opaque first coating, wherein the spherical polymer particles in the emulsion paint show a particle size distribution in which 3-10% of the particles have a particle size between 63-90 micrometers and 25-40% have a particle size between 40-63 micrometers; and wherein spherical particles are pre-pigmented, the pigment content of the particles being between 3-40 wt %.
