Sand: clean, washed silica or lime masonry sand. (Type of sand is determined by texture desired—silica sand for a fine float finish, or lime masonry sand for a skip trowel finish)…or

1. Replace the quantity of water required in your stucco mix with Mineral Life Int’l Stucco Admix.

2. For a one bag mix, about 5 gallons of Stucco Admix is required. The amount of Admix will vary according to the stucco mix design, as well as the existing moisture content of the sand in the stucco.

3. Use only enough admixture in stucco finish coat mix to make it workable.

4. Add more admixture or dry stucco mix to adjust for desired consistency, if necessary, in order to arrive at optimum consistency.

5. Add the measured stucco admix to plaster mixer, followed by the stucco mix.

6. If mixing sand and masonry cement, add the sand first followed by the cement.

7. Mix until smooth and lump free. Let stand for eight minutes, then re-mix for two minutes and apply.


1. Apply stucco with plasterer’s trowel in a tight, thin coat. Return over the fresh surface to obtain a minimum of 1/16th inch (1.5mm or a maximum of 1/8th
inch (3 mm ) thickness.

2. Feather edge finish between scaffold levels or if breaking within a wall surface, while continuing without creating excessive overlap.
