BASE: Exterior California Stucco is to be used over a base of Portland Cement undercoats (the first coat shall be mixed in the proportion of one 94 pound bag of Portland cement Type 1, one 80 pound bag of mortar Type M and 40 shovels of clean, sharp sand; for the second coat, use 44 shovels of sand.)

FRAME CONSTRUCTION: Apply waterproof building paper horizontally with each sheet overlapping 4" onto the sheet below. Over the paper, install 3.4 self-furring galvanized wire mesh overlapping and staggering, and tying with 18" gauge wire.
(Install self-furring galvanized 2.5, 3.4 or stucco mesh)

OLD BRICK: As in the case of frame construction. Hard burned brick and surfaces not sufficiently to provide a good mechanical Key (eg. monolithic concrete and where metal lath is not required, apply acrylic bonder with roller, then add 1 gallon of acrylic bonder per each bag of cement in the scratch coat. Using acrylic bonder under these conditions will insure an excellent bond.

SCRATCH AND BROWN COAT: Apply scratch coat, filling out to face lath, and double back with brown coat to such a thickness that the combined thickness of scratch and brown coats will be approx. 3/4 inch. Allow 2 weeks to cure before applying finish coat.

APPLICATION: Mix with a power mixer for at least 15 minutes to insure proper hydration. If hand mixed, allow 15 minutes slack time. Never attempt to rework material which has partly set (caution should be taken that a measured amount of water is used from one batch to the next, as this is important to control color variation). Brown coat should be uniformly moistened, but not saturated, before finish coat is applied.

In cold weather, we recommend that white stucco be chosen, instead of colored stucco, because of white efflorescence leaching out to the surface of the stucco from the cement. Stucco should not be applied unless temperature is above 40 degrees F, for two consecutive days. Caution should be taken when using a power spray application, because of separation of the aggregates from the stucco, resulting in a spotty surface.

MATERIAL STANDARDS:

• HYDRATED LIME: Meets ASTM Federal Specifications and approved by Boards of Standards and Appeals for use in New York City under calendar number 483-39-SM.
• WHITE AND GRAY PORTLAND CEMENT: Type 1. Conforms to all applicable ASTM Federal Specifications. Also approved by Board of Standards and Appeals for use in New York City under calendar #433038-SM.
• PIGMENTS: All synthetic oxides (non fading and non leaching).
• AGGREGATES: Premium blended/glass silica sand.
• PACKING: Packed in multi-walled, vapor barrier, 94 lb. bags.
• WATER PROOFING: Added to protect for all climatic conditions.

All materials used in the manufacture of our products are guaranteed to meet or surpass A.S.T.M. requirements. There is no warranty for finished work, either expressed or implied. Colors will vary due to job conditions and method of application. Color chips are approximate and slight variation of shade is to be expected, depending upon porosity of surface to be covered.

RECOMMENDED APPLICATION INSTRUCTIONS
Exterior California Stucco:

CONVENTIONAL STUCCO AND SYNTHETIC COATINGS
REFER TO ASTM, C-150, C-926, C-1063 PLUS LOCAL BUILDING CODES.

Our national experience has developed methods which produce the best stucco structure most economically. Our recommendations include a sound substrate, metal reinforcement where necessary, the correct preparation of masonry surfaces, the proper materials for the base coat, and the California Stucco, finish coat for a strong and durable finish. All these have a direct bearing on a satisfactory stucco job.

NOTE: Texture-Flex may be used as a final coat over monolithic cement, brown coat or Magna E-Z Wall Base if used with TexFlex cement bonder to assure a positive bond.
 

A) When scratch and brown coats are applied, two coats of approximately 3/8" each or a combined thickness of 3/4" are required prior to finish coat. B) It has become an accepted practice to double back with the brown coat as soon as the scratch coat is sufficiently rigid to accept the second coat. The two coats can be put into place in a single day. C) Moisten base coat for a minimum of two consecutive days. D) Allow two weeks for base coat to cure prior to applying finish coat.

E) When applying finish coat lay out to permit the completion of entire wall surface or elevation in one operation. If this is impractical the finish coat shall be carried to some natural breaking point, such as doors, windows, belt courses, inside and outside corners. F) On retaining walls, install conventional California Stucco, do not install Texture-Flex. G) When using Texture-Flex do not use galvanized accessories, use vinyl or zinc.

BLOCK / NEW BRICK Install pointed scratch and brown coats or Magna E-Z Wall, and California Stucco finish coat as in the case of frame construction. Masonry surfaces not sufficiently rough enough to provide a good mechanical key (i.e. monolithic concrete) and where metal lath is not required, a dash coat should be applied providing the surface is free from oil and other elements that would inhibit an adequate bond. California Stucco finish can then be applied. Exterior acrylic bonding agents may be used in the preparation of the masonry substrate but only under direct supervision of a journeyman plasterer.

OLD BRICK / TILE Install metal reinforcing using self-furring galvanized mesh, mailing into horizontal joints. Apply portland scratch and brown coats, or Magna E-Z Wall and California Stucco finish coat as in the case of frame construction. In the case of painted masonry where power wash or sandblasting does not reveal a good mechanical key, this procedure is required. Exterior acrylic bonding agents may be used in the preparation of the masonry substrate, but only under direct supervision of a journeyman plasterer.
