Download Superior Stucco Uniwall Spec Sheet


Manufactured from the highest-grade materials, SUPERIOR STUCCO UNIWALL provides the dependability, flexibility in design, and low maintenance that is demanded from today’s applicators. SUPERIOR STUCCO UNIWALL saves time and money overall because the completion time of the scratch and brown coats are so much faster. It is commonly used over EPS/Lath and used as a base coat for exterior finishes, such as SUPERIOR STUCCO EXTERIOR COLOR COAT or SUPERIOR STUCCO ACRYLIC FINISH.  It is fiber reinforced, light gray in color and packaged in a multi-layered, moisture resistive, 80 pound bag. SUPERIOR STUCCO UNIWALL is sold both as a Concentrate and with Sand (50lb.).  [TESTING AND STANDARDS: SEE ICC-ES REPORT# ER-5043]


SUPERIOR STUCCO UNIWALL will cover approximately 10 yards at 3/8″ thick (Concentrate).

Coverage may vary depending on the amount of sand and water used along with the various depth of your lath.


For one sack of SUPERIOR STUCCO UNIWALL Concentrate add 4 1/2 to 6 gallons of water, and 240 to 300 pounds of sand. Use clean potable water and mix in a paddle type mixer for fifteen (15) minutes for initial mix and (5) minutes thereafter. This will ensure that all materials are mixed properly. Do not add any more water than what is prescribed when mixing the product. Excessive or insufficient amounts of water can cause product failure.  Do not add any other materials to the mixture of the product without written consent of STUCCO SUPPLY.


All surfaces must be clean and free of dirt, dust, debris, grease, oils, curing agents, and cleaning solutions. Ensure that all surfaces are free of any irregularities. Do not saturate the wall during preparation.
