To water-resistant emulsified plastic based on polyvinyl acetate (PVA), 6 mm glass fibers are added, stirring in slowly over two minutes to form a porridge with distinctive fine-fiber felt-like interwoven effect. At this consistency, the suspension is coated onto the object using e.g. a palette knife. All surfaces, textured, angular and otherwise are coated, forming a smooth surface. All surfaces, textured, angular and otherwise are coated, forming a smooth surface when set, suitable for direct application of e.g. emulsion and acrylic paints. Slow stirring avoids damage to the fibers, which are also made captive, preventing health hazard. The plastic layer is tough, reinforced. Excess dispersion can be stored for future use, in a closed container, for weeks. Preferred features: Other dispersed and two-component materials can be used. Stages of the operation may be separated or combined. Other materials can be used, e.g. plastic, carbon, aramid and polyamide fibers in differing compositions. Granules may be included. Other coating processes are feasible, e.g. spraying, rolling or painting on, in machine and automatic processes.
