Abstract
Post-construction materials, including concrete, containing water insoluble polymers are disclosed herein. The water insoluble polymers are formed beneath the surface of the post-construction material using a first composition comprising a blend of fatty acid salts and a second composition comprising alkaline earth metal halides or alkaline earth metal carbonates.
Claims16
A method for treating a post-construction material having a surface, wherein the method comprises the steps of:
- applying to the surface a first composition comprising a blend of fatty acid salts each having from one (1) to four (4) acid groups and allowing a first portion of the first composition to migrate through the surface, wherein a second portion of the first composition stays on the surface;
- removing at least some of the second portion of the first composition from the surface;
- applying to the surface a second composition comprising an alkaline-earth metal halide, alkaline-earth metal carbonate, or a combination thereof and allowing a first portion of the second composition to migrate through the surface and react with the fatty acid salt beneath the surface to form one or more water insoluble polymers.
