ABSTRACT:
The present invention relates to a membrane remover/etchant solution including an organic solvent, a strong ionizable acid, a weak acid and an acid stable surfactant. The present invention further includes a method for removing a membrane and etching a concrete surface in which the membrane remover/etchant solution is in an organic solvent system and is applied to the concrete in an inactive acid form and then water is applied to activate the acid. The resulting materials are then picked up and the surface is rinsed with water.
