Improved compositions for the restoration, repair and assembly of materials include (a) a conditioner composition including a polymer that matches or is substantially the same as that to which Chemical Abstracts registry number (CAS No.) 222414-16-6 is assigned (commercially available as RHOPLEX 183
Improved compositions for the restoration, repair and assembly of materials include (a) a conditioner composition including a polymer that matches or is substantially the same as that to which Chemical Abstracts registry number (CAS No.) 222414-16-6 is assigned (commercially available as RHOPLEX 1834 acrylic emulsion) and (b) an adhesive composition that also includes a polymer that matches or is substantially the same as that to which CAS No. 222414-16-6 is assigned. Adhesive composition can also include a polymer that matches or is substantially the same as that to which CAS No. 253351-13-2 (commercially available as RHOPLEX 1950 acrylic emulsion) is assigned. First, the conditioner composition is injected into a gap between the two structures to be adhered. Next, the adhesive composition is injected into the gap. In one embodiment, the compositions are used to restore and repair historic plaster ceilings and walls.
