STONEWALL EXTERIOR STUCCO
SPECIFICATIONS

DESCRIPTION: STONEWALL EXTERIOR STUCCO is a completely prepared Portland cement base material designed for hand or machine application. All ingredients meet ASTM Standards and Government Specifications. STONEWALL EXTERIOR STUCCO is available in a wide range of colors to be selected from the STONEWALL COLOR CHART. Special colors are available upon request. STONEWALL EXTERIOR STUCCO is also prepared in 1000 and 2000 Bases for use with separate STONEWALL COLOR BOTTLES of Stonewall Standard Colors for on site job mixing. Mix one bottle of STONEWALL COLOR BOTTLE per 90lb sack of the appropriate STONEWALL EXTERIOR STUCCO base. STONEWALL EXTERIOR STUCCO is packaged in 90lb. and 25lb. sacks.
COVERAGE: One 90 lb. sack of STONEWALL EXTERIOR STUCCO covers approximately 10-15 square yards depending upon method of application and condition and type of sub-surface (I.E., rough sub-surface, poured concrete, etc.).
MIXING: Power mix for at least five minutes, adding clean water only, and bring to desired consistency. All admixtures must be approved by STONEWALL STUCCO
APPLICATION: Should be applied over a thoroughly moistened cement based plaster substrate of uniform thickness and suction. Moist cure with fog spray if required. When curing is necessary, it should be accomplished within 24 to 48 hours. If applied during hot, dry or windy conditions, curing may be required within the first few hours. This is to ensure that the cement has adequate moisture to hydrate for necessary strength and durability.
1.	FLOAT FINISH Uniformly moisten brown coat surface and allow water to dissipate. Trowel apply first finish coat approximately 1/10 inch thick. Trowel final second finish coat over the firm colored first coat to a natural break (corner, angle, screed, etc.). The joining of two color coats should not occur at same point, except at natural breaks in the wall. Float uniformly, using an absolute minimum of water and taking care not to lap finish coat joining. Total float finish coat thickness should be 1/8 inch.
2.	DASH FINISH Over brown coat the first dash application shall uniformly cover the surface and form the texture pattern. The second dash coat shall be applied after the first coat is dry. This final coat shall assure uniformity of color and texture, using care to avoid piling up of material. Over monolithic concrete apply thin "parge" coat and hand tool for maximum compaction. Allow to dry at least 24 hours. Proceed with dash application to assure uniformity of color and texture.
3.	TEXTURED FINISHES For surface treatments other than float and dash, consult "stucco textures & finishes" and/or the plastering contractor. When heavy textures are specified, the manufacturer should be informed to insure that the proper formulation is used for application of thicker coats of stucco.
SPECIAL CONDITIONS: APPLICATION OVER CONCRETE: Sandblast all surfaces prior to application of stucco. On gun applied stucco, fill all large voids with stucco just ahead of the application. ACRYLIC BONDER is recommended over all concrete substrate. ACRYLIC BONDER should be blended with the stucco at I gallon per 4 sacks. This will provide proper bond to the substrate and increase the water resistance of the stucco. APPLICATION OVER MASONRY: Apply a minimum 3/8" brown coat over masonry walls, taking care that the brown coat is properly water cured prior to the application of stucco. CURING: Extreme care should be taken when curing exterior stucco in dry weather. Do not apply water for a period of four hours after application, then fog spray very lightly and evenly, but do not saturate on first water curing. In slightly damp or foggy weather curing may not be necessary. For proper curing over concrete surfaces in extremely dry weather, a second water spray may be necessary twenty-four hours after first water spraying. SPECIAL NOTE: Under normal conditions exterior stucco produces uniform colors. To compensate for inclement weather, variations in thickness of the base coats or other circumstances leading to mottled colors, specify Portland cement fog coat of same color as exterior stucco. Follow manufacturer's mixing instructions. Apply with pressure tank sprayer after exterior stucco is thoroughly dry. If, in the contractor's judgement, conditions warrant a deviation from these standards, he becomes solely responsible for the final results.
