3.05 STUCCO APPLICATION
A. Standard: Apply stucco materials, composition, and mixes to comply with ASTM C 926.
B. Base Coats:
1. Apply the scratch coat with sufficient material and force to form good keys on metal or
wire fabric lath. Embed and fill spaces of lath and score horizontally.
2. Do not apply brown coat sooner than 48 hours after installation of the scratch coat.
Apply brown coat, bring to grounds, straighten to a true surface, float and compact,
and leave sufficiently rough to ensure bond for finish coat.
3. Do not locate cold joints of one coat over cold joints of the previous coat.
4. Do not apply finish coat sooner than 10 days after installation of brown coat. Allow
plaster to crack, wet down, and let dry before finish coat.
C. Finish Coats: Finish stucco true and even within 1/8-inch tolerance in 5 feet, and leave the
finished surfaces free from tool marks and other blemishes.
1. Texture: Medium sand float. Apply finish stucco to an approximate thickness of
1/8 inch and uniformly float to a true, even plane.
a. Trowel on a finish coat and double back with a second application. Formulate
stucco mix with a 20-mesh aggregate.
b. Using circular motion, rub surface with float to achieve uniform pattern, bringing
sand particles to surface. Use an absolute minimum of water in floating.
D. Curing: After application, each base coat of portland cement stucco shall contain sufficient
moisture to assure hydration for at least 48 hours. If necessary to moisten stucco, avoid
soaking and apply water in fine fog spray. Do not apply stucco to surfaces which contain
surface water.
3.06 STUCCO PATCHING/REPAIR
A. Cut, patch, replace, repair, and point up stucco as necessary to accommodate other work.
Repair cracks and indented surfaces. Point up finish stucco surfaces around items that are
built into or penetrate stucco surfaces. Repair or replace work to eliminate blisters, buckles,
check cracking, dryouts, efflorescence, excessive pinholes, and similar defects. Repair or
replace work as necessary to comply with required visual effects.
3.07 CLEANING
A. Remove temporary covering and other provisions made to minimize spattering of stucco on
other work. Promptly remove stucco from door frames, windows, and other surfaces not to
be stuccoed. Repair surfaces stained, marred, or otherwise damaged during stuccoing
work. When stuccoing work is completed, remove unused materials, containers, equipment,
and stucco debris.
B. Provide final protection and maintain conditions, in a manner acceptable to manufacturer
and installer, that ensure stucco work is without damage or deterioration at the time of
Substantial Completion.
