摘要
A protective product for treating fresh concrete or mortar. The products are a mixture of (a) an aqueous dispersion A of a film-forming synthetic polymer (the synthetic polymer is compatible with fresh concrete or mortar) having little or no permeability to water vapor with (b) at least one coagulant for the film-forming synthetic polymer when in the presence of calcium ions. The coagulant is introduced in the form of an aqueous or aqueous alcoholic solution and/or by means of an aqueous wax emulsion and/or by means of an aqueous dispersion B of a synthetic polymer which is slightly permeable or impermeable to water. The aqueous dispersion B is prepared by polymerization in the presence of the coagulant. When applied by spraying to the surface of fresh mortar, the products form a continuous waterproof film, which is readily removed by peeling.
