George Douglass House Restoration Report for the quarter endinng June 30, 2021 |
Description |
George Douglass House Restoration Project-Work Accomplished and In-Progress-2d Quarter 2021 Second quarter work in 2021 focused on plastering deteriorated areas, wall segments with partial or total de-lamination of original 1765 and/ or later applications, and patching voids. In the process of removing deteriorated or de-laminated plaster remnants in the original Amity Store space, it became apparent that the sub-strate stone walling was in many places poorly laid-up or otherwise unstable. Problem areas had suffered dislocations of some stone units and/or significant voids between stones. Based on these conditions, the preparation for base and finish plaster coatings required extensive and un-anticipated masonry stabilization, infilling with additional well-fitting stones, re-mortaring deficient areas, including "deep pointing" to fill-in beds and joints, and "flush" pointing set back just enough to create slightly recessed "keys" to help anchor the plaster base coat to the masonry. Similar stabilization, restoration, and finish plastering will take place in the parlors and kitchen. Second quarter work-in-progress and completed elements:Interior: Original Amity Store room: 1.The left stone jamb of the doorway from the original store room in the 1765 house-block to the c. 1798 store addition, showing dislocated stones and voids between stones, an extremely unstable structural condition. Simply "plugging" these gaps with mortar is not an effective solution and would not conform to current preservation standards [Photo 13, 6/4/21]. The jamb to the right [west] of the doorway was similarly at risk of failure [Photo 10, 6/4/21]. 2.Restored left doorway jamb after insertion and "mudding-in" of selected stones set and secured with bed and joint mortar applied in incremental "lifts" and continually moistened to meter the curing process, creating a durable monolithic wall structure and a sound backing for the restored plasterwork [Photo 11, 7/7/21]. 3.Masonry headwork above store doorway, stabilized and flush-pointed to establish a reasonably regular plane to anchor the lime-plaster base-coat [Photo 1, 7/2/21]; Photo #10, 7/7/21 shows the same area after application of the base coat; margins of original undisturbed plaster delineate the repaired area and the finish-surface to be met, lift-by-lift. 4.Back parlor: (a) Base coat plaster infill above baseboard adjacent to fireplace [Photo 27, 6/4/21]; (b) chopped "keys" in surface of base plaster in wainscot panel below chair rail, awaiting finish coats of plaster [Photo 22, 6/4/21]; (c) base-coated fireplace masonry [Photo 4, 6/12/21]. A.Exterior: 5.Pent-roof framing with white oak at its original elevation across the 1765 façade, supported on joist extension "outlookers" ("cantilevers", in mechanical terms) with varying-separations, after setting rafters and pedimented hood trusses,the rafters to be lathed and covered with western red cedar shingles, and ceiled with boards [Photo 1, 6/16/21]. Rafters bear on a rafter plate leveled across the outlookers [Photo 31, 6/4/21]. Larry Ward |
