water until the mixture is uniform in color and consistency. Avoid excessive mixing or agitation.

Discard plaster which has begun to set before it is used; re-tempering will not be permitted. Do

not use caked, or lumped materials. Empty mixers and mixing boxes after each batch is mixed,

and keep free of old plaster.

PART 3 - EXECUTION

3.1 PREPARATION OF SURFACES

Clean surfaces to which plaster is to be applied of all projections, dust, loose particles, grease,

bond breakers, and foreign matter. Do not apply plaster directly to (1) surfaces of masonry or

concrete that has been coated with bituminous compound or other waterproofing agents, or (2)

to surfaces that have been painted. Before plaster work is started, wet masonry and concrete

surfaces thoroughly with a fine fog spray of clean water to produce a uniformly moist condition.

Check metal grounds, corner beads, screeds, and other accessories carefully for alignment

before the work is started. Check expansion and control joints and supporting metal structures

to ensure that expansion and control joints can move unrestrained.

3.2 APPLICATION OF PLASTER

3.2.1 General

Plaster may be applied by hand or by machine. When a plastering machine is used the fluidity of

Portland cement-lime plaster shall be controlled to have a slump of not more than 63 mm when

tested using a 50 by 100 by 150 mm high slump cone. Subsequent to determining water content

to meet this slump, do not add additional water to the mix. Conduct the slump test according to

the following procedure:

a. Place cone on level, dry, non-absorptive base plate.

b. While holding cone firmly against base plate, fill cone with plaster taken directly from the

hose or nozzle of the plastering machine, tamping with metal rod during filling to release

air bubbles.

c. Screed off plaster level with top of cone. Remove cone by lifting it straight up with a slow

and smooth motion.

d. Place cone in a vertical position adjacent to freed plaster sample, using care not to jiggle

base plate.

e. Lay a straight edge across top of cone, again being careful not to vibrate cone. Measure

slump in inches from the bottom edge of the straightedge to the top of the slumped

plaster sample.

3.2.2 Workmanship

Apply plaster in three coats, except as follows:

a. Provide scratch coat. Apply base coats with sufficient pressure and plaster shall be

sufficiently plastic to provide a good bond to bases. Work base coats into screed at



4 of 5

intervals of from 1.50 to 2.40 meters. Plaster shall not be continuous across expansion

and control joints occurring in walls, and partitions. Finish plasterwork level, plumb,

square, and true, within a tolerance of 3 mm in 2.40 meters, without waves, cracks,

blisters, pits, crazing, discoloration, projections, or other imperfections. Form plasterwork

carefully around angles and contours, and well up to screeds. Special care shall be

taken to prevent sagging and consequent dropping of applications. There shall be no

visible junction marks in finish coat where one day’s work adjoins another.

3.3 PORTLAND CEMENT – LIME PLASTER

Apply base coats with sufficient pressure to curl the keys around the back of metal lath or wire

fabric and to provide good bond on masonry or concrete bases.

3.3.1 Plaster except Scratch Coat for Ceramic Tile Backing

Apply in three coats to a thickness of not less than 16 mm. Apply the scratch coat not less than

6 mm thick, lightly score horizontally, and moist cure for not less than 24 hours. Apply the brown

coat after the scratch coat has been aged at least 24 hours in addition to the moist curing period.

Apply the brown coat to bring the base coat out to the screeds, compact and straighten to a true

surface with rod and Darby, and float to receive the finish coat. After the brown coat has been

moist cured for not less than 24 hours and aged at least than additional 5 days, apply the finish

coat to a thickness of not less than 3 mm. Where any previous coat has become dry, dampen

the surface evenly with water, prior to the application of the next coat. The finish coat for plaster

shall have a troweled finish. Moist cure plaster for 24 hours using a fine fog spray of water and

apply to the finish coat as frequently as required to prevent dry-out of the plaster. Do not

saturate the plaster to the point where free water stands on the surface. Prevent staining of the

finish coat. Provide moist curing.

3.3.2 Scratch Coat for Ceramic Tile and Marble Backing

Apply scratch coat and keep continuously damp for not less than 24 hours before tile is to be set.

Apply scratch coat in thickness indicated or as necessary to bring the face of the tile and marble

to the required plane, but not les than 6 mm from the face of the material it is being applied to

and with a level surface within a tolerance of 6 mm in 2.40 meters. Apply scratch coat after

substantial grounds, plugs, hangers and other electrical outlets, and other fixtures and fittings

have been installed that are to be secured to tiled and marbled surfaces. Apply scratch coat with

sufficient pressure to ensure a proper bond and key with the base and a proper base for the

setting bed. While the mortar is still plastic, cut the scratch coat with a trowel at internal vertical

angles to the depth of the coat and for the full height of the tile bed, score horizontally or cross-

scratch coats within one hour after mixing, and at no time shall the mortar be re-tempered.

Protect scratch coat and keep moist during curing period. A leveling coat of the same mix

specified for the scratch coat shall be applied over the scratch coat when the surface of the

scratch coat is not level within the specified tolerance or when a base coat thickness of more

than 19 mm is required. Scratch leveling coat and cure for not less than 24 hours.

3.4 PATCHING AND POINTING

Upon completion of the building, cut out and patch loose, cracked, damaged, or defective

plaster. Patching shall match existing work in texture, color and shall be finished flush with

plaster previously applied. Do pointing and patching of plaster work abutting or adjoining any

other finish work in a neat and workmanlike manner. Remove plaster droppings or spattering

from surfaces, in condition ready to receive paint or other finish. Remove protective covering

from floors and other surfaces, and rubbish and debris from the building.

PART 3 - EXECUTION

3.1 PREPARATION OF SURFACES

Clean surfaces to which plaster is to be applied of all projections, dust, loose particles, grease,

bond breakers, and foreign matter. Do not apply plaster directly to (1) surfaces of masonry or

concrete that has been coated with bituminous compound or other waterproofing agents, or (2)

to surfaces that have been painted. Before plaster work is started, wet masonry and concrete

surfaces thoroughly with a fine fog spray of clean water to produce a uniformly moist condition.

Check metal grounds, corner beads, screeds, and other accessories carefully for alignment

before the work is started. Check expansion and control joints and supporting metal structures

to ensure that expansion and control joints can move unrestrained.
