B. Examine existing surfaces to decide areas where plaster coats are detached from each other or from laths or masonry behind.

C. Remove old loose, cracked, flaking, delaminating, and structurally unsound plaster down to acceptable plaster base, lath, or masonry substrate. Remove plaster exhibiting efflorescence to substrate.

D. Remove old wallpaper, loose and flaking paint and surface finish adjacent to holes and cracks.

E. Cut back into sound plaster at an angle to form a dovetail key to ensure adequate connection between new plaster and existing plaster.

F. Clean masonry substrates in a manner acceptable to plaster manufacturer.

G. Remove old wood lath which is damaged, rotted or otherwise unsuitable for reuse. Remove dirt, debris, corroded fasteners and other materials which may interfere with performance of repairs and new plaster.

H. Re-nail and otherwise secure loose wood lath. Install new wood lath to match existing. Install new metal lath over repaired areas of wood lath. Retie broken wire ties on existing metal lath.

I. Clean concrete surfaces of foreign matter. Thoroughly dampen surfaces before using acid solutions, solvents, or detergents. Wash surfaces with clean water.

J. Roughen smooth concrete surfaces and smooth faced masonry.

3.2 INSTALLATION - LATH MATERIALS

A. Apply metal lath taut, with long dimension perpendicular to supports, to entire area to be re-plastered, such as areas over existing masonry substrates and over existing wood lath.

B. Cut lath slightly smaller than the area to be patched and nail into place. Lap ends minimum 1 inch. Secure end laps with tie wire where they occur between supports.

C. Lap sides of diamond mesh lath minimum 2-inches over existing lath and new lath. Nest outside ribs of rib lath together.

3.3 CRACK REPAIR 04/01/2020

A. Hairline Cracks: 1. Widen crack slightly with a sharp, pointed tool such as a crack widener or a triangular can

opener. Then fill crack. For more persistent cracks, bridge crack with tape. In this instance, a fiberglass mesh tape is pressed into patching material.

2. After first application of a quick setting joint compound dries, a second coat is used to cover the tape, feathering it at edges. A third coat is applied to even out surface, followed by light sanding.



The area is cleaned off with a damp sponge, then dried to remove any leftover plaster residue or dust.

B. Larger than Hairline Cracks: 1. Repair larger than hairline cracks in areas of otherwise sound plaster. Carefully cut out cracks

to 6 inches wide with a chisel or knife and form a dovetail key for the repair. 2. Thoroughly clean cracks of loose debris and dust. Spray lath exposed in crack with water to

prevent excessive suction of water from new plaster mix. Apply bonding agent to edges of old plaster. Apply metal lath cleared area, leaving existing wood lath in place.

3. Fill cracks with fresh plaster. Embed fiberglass fabric in fresh plaster over cracks and sand after plaster dries. Flat tape cracks adjacent to door frames, base and window trim.

4. Flat tape large, filled cracks in corners, then angle tape. Tape corner cracks after adjacent surfaces have been repaired. Finish with a broad feathered plaster repair, 15 to 18 inches wide.

3.4 PATCHING HOLES

A. Small Holes: 1. Make repairs in two applications. First, trowel a layer of base coat plaster in place and scrape

back below level of existing plaster. 2. When base coat has set but not dried, apply more plaster to create a smooth, level surface. Do

not do one-coat patching.

B. Large Holes: 04/01/2020 1. Where all three coats of plaster are damaged or missing down to wood, clean out old plaster

and lath. Re-nail loose lath. Apply a bonding agent. 2. Attach expanded metal lath (diamond mesh) to wood lath with tie wires or nail over wood lath

with lath nails. 3. Apply plaster in three layers over metal lath, lapping each new layer of plaster over old plaster

so that old and new are evenly joined.

3.5 PLASTERING

A. Thoroughly wet old wood lath surfaces as needed to control excessive suction and prevent rapid removal of water from new plaster. Apply bonding agent to edges of old plaster.

B. Apply gypsum plaster in multiple applications per manufacturer's instructions. One-coat applications will not be permitted.

C. Repair delaminated areas of finish coat. Apply bonding agent and new finish coat. Delaminated but otherwise intact ceiling areas may be reattached to lath using flathead wood screws and plaster washers.

D. Allow plaster to cure properly before applying paints under Section 099000. Paint in and around plaster patch. Feather paint out to blend in with surrounding surfaces. 04/01/2020
