ABSTRACT:
A masonry method uniquely adapted for repairing structures constructed of adobe members whereby the broken or eroded portion of disfigured members is removed from the structure to create a void and expose an interface, the interface is cleaned, the cleaned interface is painted with a coating composition; the void is packed with a filling which intimately engages said coated interface and extends therefrom in a mass which is shaped to recreate the contour of the original adobe member; and the shaped mass is painted with said coating composition and allowed to cure. The coating composition comprises a modified acetate homopolymer formed in an emulsion having between 55.0 and 57.0 percent total solids, a mean particle size of 5 microns, a viscosity of between 500-1000 Cps, a pH of from 5.5 to 7.0 and diluted with an equal volume of water. The filling composition contains preselected portions of Portland cement, finely screened washed sand and a preselected amount of adobe dust mixed in water to create a plastic mixture having a trowelling consistency.
