<p>Elastomeric coatings capable of reverting to their initial dimensions for the permanent bridging of joints and cracks in facades, walls and ceilings of old and new constructions, industrial floors, constructions at subgrade level, using coating materials which are deposited and dried employing coating apparatus known per se by painting, plastering, caulking or spraying or rolling. The coating materials are prepared from aqueous emulsions and/or aqueous dispersions and/or solutions of film forming binders in organic solvents possibly containing water, possibly also containing pigments, extenders, fillers, softeners, admixtures and additives and furthermore contain a fine-particle, elastomeric powder dispersed through the coating materials which dry into elastomeric films.</p> |
