WORKMANSHIP-Plastering personnel should follow practices defined under ASTM C-928 (Standards for Application of Portland Cement Based Plaster)
WATER- The amount of water needed depends on the water content of the sand and the personal preference of the plastering contractor. Add water until the blended components of cement sand and water reach the workability desired by a qualified plasterer.
SAND- Use plaster sand that conforms to ASTM C-897. (Specification for Aggregate for Job-Mixed Portland Cement-Based Plasters)
General Mixing Instructions for scratch & brown stucco mixes:
(It is suggested that you mix this or similar products with the use of a motorized mortar mixer)
For scratch stucco coats or for brown stucco coats- Use 1 bag of Spectrum Fiber Reinforced Scratch & Brown Coat to 2.5-3.25 cubic feet of plastering sand.
(The volume of sand used may be slightly more or less than mentioned above if so determined by a qualified plastering contractor)
First: add approximately 2/3 of the required water, 1/2 of the required sand into the mixer and allow that to mix briefly.
Next: add 1 bag of Spectrum Scratch & Brown Coat, the remainder of the sand and sufficient water to bring the mix to the desired workability. These components should be mixed a minimum of 5 minutes after all materials have been added to the mixer. It is recommended that a 1 cubic foot box or similar measuring tool be used to measure the sand. This will insure consistent color, uniformity and strength.
Product conforms to ASTM C-1328 Type S and ASTM C-926 Type CM when applicable.
