PRODUCTS

LIME-PLASTER MATERIALS

Hydrated Lime: ASTM C 202, similar to existing.

Retain "Finish-Coat Sand" Subparagraph below for sieve requirements different from ASTM C 897; retain option below only if required for exposed lime plaster.

Type S.

Type N Lime Putty: similar to existing.

Retain "Finish-Coat Sand" Subparagraph below for sieve requirements different from ASTM C 897; retain option below only if required for exposed lime plaster.

Slaked hydrated lime.

Factory prepared lime putty according to ASTM 1489.

Sand Aggregates: ASTM C 897.

Retain "Finish-Coat Sand" Subparagraph below for sieve requirements different from ASTM C 897; retain option below only if required for exposed lime plaster.

Finish-Coat Sand: Match to similar and compatible size, texture, and gradation of existing sand as closely as possible.

Pigments for Colored Plaster: ASTM C 979/C 979M and having a satisfactory performance in lime plaster.

Retain "Fiber" Paragraph below for base-coat plaster; revise to suit Project.

Fiber: Verify and match existing, free of grease, waxes, and oils; and beaten well to separate fibers before blending into unfibered plaster material.

Proportion of Fiber to Unfibered Plaster Material: adjust proportion as required to produce a well-fibered, cohesive, spreadable, stiff mix with fibers uniformly distributed.

TRIM ACCESSORIES

General: According to: ASTM C 1063 for lime plaster; coordinate depth of trim and accessories with thicknesses and number of plaster coats required.

MISCELLANEOUS MATERIALS

Water that contains salt, alum, or plaster residue accelerates plaster set and may cause efflorescence. Water that contains organic or vegetable matter may retard plaster set, cause staining, and interfere with plaster bond.

Water for Mixing and Finishing Plaster: Potable and free of substances capable of affecting plaster set or of damaging plaster, lath, or accessories.

Fasteners for Attaching Lath to Substrates:

For Lime Plaster: ASTM C 1063.

For Gypsum Plaster: ASTM C 841.

For Wood Lath: ASTM C 841 requirements for wood-floor-runner or wood-furring fasteners unless otherwise indicated on Drawings.

Generally, retain "Wire Ties" Paragraph below. Wire, in various diameters, is used for tying expanded-metal lath to framing and supports.

Wire Ties: ASTM A 641/A 641M, Class 1 zinc coating, soft temper, not less than 0.0475-inch diameter, unless similar to existing.

EXECUTION

TREATMENT OF PLASTER, GENERAL

General: In treating historic plaster, disturb it as minimally as possible and as follows unless otherwise indicated:

Dismantle loose, damaged, or deteriorated plaster, lath, and support systems that cannot be repaired.

Verify that substrate surface conditions are suitable for repairs.

Provide lath, furring, and support systems for plaster included in the work of this Section.

Replace lost details in new, wet-applied and cast plaster that replicate existing or indicated plaster configurations.

Leave repaired plasterwork in proper condition for painting or applying other finishes as indicated.

Install temporary protective measures to protect plaster surfaces that shall be treated later.

PATCH-TYPE REPAIR

Patch-type repair mixes can vary widely depending on base plaster type, patch size and shape, and Installer's preferences. A repair mix should finish well and shrink little. Often, gypsum products are used with cracked lime-plaster to speed setting and reduce shrinkage.

General: Patch voids, fractured surfaces, and crushed areas as a result of removal and installation work of double doors.

Inspect for deterioration of supporting plaster and lath, and repair or replace deteriorated material as required for a sound substrate.

Rake perimeter of hole to sound plaster, and slightly undercut existing plaster to enable replacement plaster to tuck behind existing plaster.

Replace missing lath in kind. Bridge gaps in wood lath with expanded-metal lath, overlapping wood by 6 inches and fastening them together.

Clean hole to remove loose materials and other foreign matter and deposits that could impair bond with repair material.

Wet substrate to damp condition, but without visible water droplets, then install patch material to original profiles.

First option in "Lime-Plaster Mix" Paragraph below is sometimes used for small patches; revise to suit Project. Retain last option below if using fiber in first coat of two-coat patch.

Lime-Plaster Mix: shall be similar to existing in kind, type and plaster material components.

First option in "Gypsum-Plaster Mix" Paragraph below is sometimes used for small patches; revise to suit Project. Retain last option below if using fiber in first coat of two-coat patch.

Finishing: Finish flat surfaces flush and with same texture as adjacent existing plaster. For molded plaster shapes, tool surface to restore the sharp edges and the shape of the molded shape to original contours.

Hairline cracking within the plaster or plaster separation at edge of a patch is unacceptable. Completely dismantle such work and reinstall or repair.
