PART 3 EXECUTION

3.1 APPLYING METAL PLASTERING BASES

In accordance with ASTM C1063-12c , except as otherwise specified or shown.

2. Install control joints only to the edges of abutting sheets of lath so that the lath is not continuous or tied across the joint.

SECTION 09 24 00 Page 4

3. Extend joints the full width and height of the wall or length of soffit/ceiling plaster membrane.

3.3 SURFACE PREPARATION OF SOLID BASES

Prepare and condition surfaces that are to receive plaster in accordance with ASTM C926-12a , except as otherwise specified.

3.4 PORTLAND CEMENT BASED PLASTER

A. Apply stucco in three coats to a thickness of not less than 25 mm (1 inch) as measured from the back plane of metal reinforcement, exclusive of ribs or dimples or from the face of solid backing or support, with or without metal reinforcement, to the finished stucco surface, including moderate texture variations.

B. Conform to the applicable requirements of ASTM C926-12a and the following:

1. Evenly dampen masonry surfaces to receive stucco immediately prior to application of stucco.

2. Apply each stucco coat continuously in one general direction, without allowing mortar to dry at edges. Where it is impossible to work the full dimensions of a wall surface, in a continuous operation, jointing to be made at a break, opening, or other natural division of the surface.

3. Dampen edges to be jointed to produce a smooth confluence.

4. Slightly round exterior corners.

5. Pitch Portland cement plaster on soffit surfaces forward to form a drip.

6. Scratch Coat:

a. Apply not less than 10 mm (3/8 inch) thick under sufficient pressure to form good keys and to completely embed the reinforcement.

b. Lightly scratch before the scratch coat has set, in one direction; scratch vertical surfaces in the horizontal direction only.

c. Fog cure scratch coat for a minimum of 72 hours.

7. Brown Coat:

a. Dampen the scratch coat evenly to obtain uniform suction before the brown coat is applied; there cannot be visible water on the surface when the brown coat is applied.

b. Apply the brown coat to the scratch coat with sufficient pressure to force the stucco into the scratches and brought to a plumb, true, even plane with rod or straightedge.

c. Uniformly float brown coat with dry float when set sufficiently, to promote densification of the coat and to provide a surface receptive to bonding of the finish coat.

d. Fog cure brown coat for a minimum of 72 hours.

SECTION 09 24 00 Page 5

8. Finish Coat:

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

b. The finish coat to have a smooth trowel finish and matching the approved sample.

c. Fog cure finish coat for a minimum of 48 hours; take care to prevent staining.

3.5 CURING AND PROTECTION

A. Perform fog curing by applying a fine mist of water to the Portland cement plaster.

B. Exercise care during fog curing to avoid erosion damage of the stucco surfaces.

C. Do not use a solid stream of water.

D. Frequency of fogging cannot be less than three times daily.

E. Protect the stucco from the direct rays of the sun during severe drying conditions using canvas, cloth, or other approved sheet material, when directed.

3.6 PATCHING AND POINTING

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

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

3.7 TOLERANCES

A. Do not deviate more than 6 mm in 3 m (1/4 inch in 10 feet) from true plane in finished plaster surfaces as measured with a 3 m (10 foot) straightedge.

B. Finish plaster flush with metal accessory surfaces and other built-in items unless otherwise directed.
