2.9 BONDING AGENT

ASTM C631, interior application.

PART 3 EXECUTION

3.1 SURFACE PREPARATION

A. Clean surfaces before application of gypsum plaster of projections, dust, loose particles, grease, bond breakers, and foreign matter. Do not apply plaster directly to surfaces (1) of masonry or concrete that have been coated with bituminous compound or other waterproofing agents, or (2) that have been painted or previously plastered. 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 starting work. Do not apply gypsum plaster to surfaces containing frost.

B. Anticipate that both existing plaster and painted finishes contain asbestos containing materials and proceed accordingly.

C. For cracks, break away any loose pieces of plaster and lightly sand the surface with a medium-grit sandpaper. Wipe the area clean with a clean towel. Fill the crack with base plaster. If the crack is over 1/4 inch wide, place a piece of fiberglass tape over the crack and base plaster. Allow the base plaster to dry. Apply a second coat of finish plaster, feathering it out along the wall. Allow the finish plaster to dry. Sand the surface with a fine-grit sandpaper after the finish plaster has dried until surface matches existing adjacent.

D. For holes break away loose plaster and wipe the area lean with a towel. Fill the hole with a base coat of plaster using a medium-width trowel. Scrape the plaster compound so that it sits 1/4 inch below the finished surface of the plaster. Allow the plaster to set, but not dry. Apply a second coat of finish plaster using a trowel. If the hole is larger than 4 inches , scrape the plaster out until it is just below the existing surface of the wall. Otherwise, smooth the plaster using the straight end of the trowel until it is flush with the rest of the wall and smooth in appearance. Apply a third coat of finish plaster, if necessary, once the previous coat has set but not dried.

Smooth the plaster until it is seamless against the rest of the wall using a trowel. Once the plaster has dried completely, lightly sand with fine-grit sandpaper if he plaster did not dry completely smooth.

3.2 WORKMANSHIP

3.2.1 Slump Tests

Apply Plaster by hand. Subsequent to determining water content to meet the specified slump, do not add additional water to the mix. Conduct the slump test according to the following procedure:

SECTION 09 23 00 Page 5

3.2.2 Application

Apply gypsum plaster in three coats, except as follows:

Gypsum plaster applied to masonry using the two-coat double-up method.

Apply base coats with sufficient pressure and ensure plaster is sufficiently plastic to provide a strong bond to bases. Work base coats into screeds at intervals from 5 to 8 f eet . Plaster must not be continuous across expansion and control joints occurring in walls, partitions, and ceilings. Finish work level, plumb, square, and true, within a tolerance of 1/8 inch in 8 f eet , without waves, cracks, blisters, pits, crazing, discoloration, projections, or other imperfections. Form plaster work carefully around angles and contours, and well-up to screeds. Take special care to prevent sagging and consequent dropping of applications. There must be no visible junction marks in finish coat where one day's work adjoins another.

3.2.3 Curing

3.2.3.1 Gypsum Plaster

Before the plaster has set, provide environmental controls to prevent the plaster from drying too fast. After the plaster has set, provide for rapid drying to develop high strength.

3.3 GYPSUM PLASTER WORK

ASTM C842.

3.3.1 Gypsum Plaster Thickness Requirements

Match original thickness .

3.3.2 Gypsum Plaster Basecoat Work

3.3.2.1 Gypsum Two-Coat System

Apply the first coat to cover the base with sufficient material and pressure to form a good bond on the wall or ceiling base. Before the first coat has set and without scratching or cracking the surface, apply a second coat (double back) of the same material proportion as the base coat to the screeds. Straighten to a true surface without application of water, and cross rake or scratch to receive the finish coat.

3.3.3 Gypsum Plaster Finish Coats

Moderately moisten or fog spray base coat of plaster that has become dry before finish coat is applied. Accelerate plaster, if necessary, to provide a setting time of not more than 4 hours from the time the plaster is mixed.

3.3.3.1 Lime-Putty and Gypsum-Gauged Finish Coats

Apply lime-putty gypsum-gauged finish white coat or aggregated white coat and high strength gypsum gauged finish over the base coat, scratch in thoroughly, lay on well, double back, and fill out to a true, even surface. Allow the finish to dry a few minutes, then trowel well with

SECTION 09 23 00 Page 6 water. Apply maximum pressure in order to compact the finish coat and provide a smooth finish free from blemishes and irregularities. Apply trowel finish coats of gypsum-gauged lime-putty over properly prepared base coats as thin as possible and 1/16 to 1/8 inch thick for conventional plaster system, except as necessary in spots to level out hollows in base coat.

3.4 PATCHING AND POINTING

Cut out and patch loose, cracked, damaged, or defective gypsum plaster.

Patch must match existing work in texture, color and finish flush with previously applied gypsum plaster surfaces. Point work abutting or adjoining finish work in a neat manner. Remove droppings or spatterings from surfaces. Leave clean and in a condition to receive paint or other finish. Remove protective covering from floors and other surfaces, and rubbish and debris from the interior and exterior of the building.

Stucco application must conform to the applicable requirements of ASTM C926 and the following:

3.4.1 Workmanship

Items or features of the work in connection with or adjoining the stucco must be in place, plumb, straight, and true prior to beginning the stucco work. Concrete and m asonry surfaces to receive stucco must be evenly dampened immediately prior to application of stucco. Each stucco coat must be applied continuously in one general direction, without allowing mortar to dry at edges. Where it is impossible to work the full dimension of a wall surface in a continuous operation, jointing must be made at a break, opening, or other natural division of the surface. Edges to be joined must be dampened slightly to produce a smooth confluence. Exterior corners of stucco must be slightly rounded. Stucco on soffit surfaces must be pitched forward to form a drip.

3.4.2 Scratch Coat

The scratch coat must be fog cured for a minimum of 72 hours.

3.4.3 Brown Coat

Evenly dampen the scratch coat to obtain uniform suction before the brown coat is applied. There must be no visible water on the surface when the brown coat is applied. The brown coat must be applied to the scratch coat with sufficient pressure to force the stucco into the scratches and must be brought to a plumb, true, even plane with rod or straightedge. When set sufficiently, the brown coat must be uniformly floated with a dry float to promote densification of the coat and to provide a surface receptive to bonding of the finish coat. Brown coat must be fog cured for a minimum of 72 hours.

3.4.4 Finish Coat

Dampen surfaces of the brown coat not more than 1 hour before the finish coat is to be applied to a uniform wetness with no free-standing water on

SECTION 09 24 23 Page 3 the surface. The finish coat must have a rough-textured finish to match existing adjacent and must conform to the approved sample. Fog cure the finish coat for a minimum of 48 hours. Take care to prevent staining.

3.4.5 Surface Tolerance

When a 10 foot straightedge is placed at any location on the finished surface of the stucco, excluding rough-textured finish, the surface must not vary more than 1/8 inch from the straightedge.

3.5 CURING AND PROTECTION

Perform fog curing by applying a fine mist of water to the stucco.

Exercise care during fog curing to avoid erosion damage of the stucco surfaces. Do not use a solid stream of water. Fog not less than three times daily. Protect the stucco from the direct rays of the sun during severe drying conditions using canvas, cloth or other approved sheet material.

3.6 PATCHING AND POINTING

Replace or patch loose, cracked, damaged or defective work as directed.

Patching must match existing work in texture and color and must be finished flush.
