<p>Protective coatings, in particular for the purpose of shielding and waterproofing buildings and engineered outdoor structures are based on mixtures of polymer crude tall oil pitch, in particular mixtures of an aqueous emulsions of tall oil pitch with an aqueous polymeric latex. Superior waterproofing/coating compositions according to the invention may be made as a two- component sprayable system comprising a first part which is a mixture of a alkali carbonate modified tall oil pitch emulsion and one or more polymeric latexes, and a second part which is an aqueous solution of a bivalent cationic curing agent.</p> |
