A floor, wall or ceiling surface is covered by applying a liquid, solvent-free cold-curing synthetic resin composition and a curing agent for the resin selected so that the hardening of the resin by the curing agent is not instantaneous, electrostatically depositing textile fibre flock on the surface of the resin before it has hardened to an extent such that the flock particles cannot penetrate, at least partially, the surface and thereafter allowing the completion of the cure of the resin at room temperature. The surface can be jointless composition flooring, a cementbound jointless composition, compositions based on binders such as lime and gypsum and on bitumen or asphalt, concrete, artificial stone, plaster and wood, particularly wooden floors. The term "solvent-free" is defined as not containing a volatile organic solvent. Solvents that participate in the curing reaction may be present, e.g. styrene, vinyl toluene, acrylic acid esters, methacrylic acid esters. Suitable solventfree compositions are those based on non- thermoplastic polymers such as (1) hydroxyl group-containing compounds such as polyethers, polyesters, alkyd resins, acrylic and epoxy resins (which cure with polyisocyanates), (2) epoxy resins (which cure with the aid of polyamines, amidoamines or ketimines), (3) acrylic compounds or unsaturated polyesters mixed with copolymerizable monomers, e.g. styrene, vinyl toluene, acrylic acid esters, methacrylic acid esters (which cure with peroxides), (4) polysulphides (which cure with heavy metal peroxides, e.g. lead peroxide or manganese dioxide). The curing agent may be admixed with the resinous materials before processing, or alternatively a curing agent and the resinous material can be applied separately on to the surface by a two-component spray device, or the curing agent can be applied first followed by, in a separate operation, the application of a layer of the resinous material. The resinous materials may contain pigments and/or fillers such as talc, barium sulphate, mica, asbestos, quartz or sand. The compositions may be applied by brushing, roller, spraying, casting or trowelling. Suitable textile fibres are of cotton, coconut, wool, goat hairs, viscose rayon, triacetate or polyamide flock, and are preferably of length 0À3 to 12 mm. The flocking may be carried out using screen diffusers in an electrical hightension field or by means of electrostatic spray guns. The fibres may be of uniform or varying length, or fibres of different length can be incorporated by flocking in two or more successive operations, and fibres of different colours can be used.</p> |
