Abstract: Plastic elastic wall coatings for the building industry for use on external and internal walls are described which comprise a paste of thermoplastic acrylic resins in the form of an emulsion of high content of solid materials, the solid materials being inert siliceous materials, carbonates, silicates, inorganic pigments, synthetic or mineral fibers, water repellent substances based on a wax or silicone derivatives and additives which are bactericidal agents, fungicidal agents and agents capable of causing the resin to set. The coatings exhibit high elasticity which is maintained with the passage of time and which permits to withstand great changes in temperature and variations in climate.
