Product Details


  • Concrete and Plaster Surfaces: All masonry should be twenty-eight (28) days cured and shall be structurally sound, clean, and free of any moisture, wax, oil, paint particles, curing agents, or foreign matter. Remove any liquid curing agents or concrete sealers, followed by a clear water wash.


Using a clean mortar box or mechanical mixer, add sufficient cool clean potable water to desired, plastic-like, consistency. For additional strength and performance add Southcrete™ 25 Acrylic Mortar Admix in lieu of water. Do not re-temper mortar mix; discard and prepare fresh mix. Machine mixing is preferred.

  • NOTE: All cement-based products have the potential for efflorescence to materialize. This whitish powder or crystalline deposit may become visible before, during, or after installation is completed. Water with a high mineral content can also cause efflorescence.




Product is alkaline on contact with water. Use paddle for mixing to avoid splashing into eyes or contact with skin. During mixing or application avoid contact with eyes. In case of such contact, flood eyes repeatedly with water and CALL A PHYSICIAN. Wash thoroughly after handling and before smoking or eating. Do not take internally. CONTAINS FREE SILICA — DO NOT BREATHE DUST. Prolonged exposure to dust may cause delayed lung disease (Silicosis).

WARNING: This product may expose you to chemicals, including silica, which the State of California recognizes as a cause of cancer. For more information, visit the Proposition 65 Warnings Website (www.P65Warnings.ca.gov). Use NIOSH approved masks at all times to handle silica dust. KEEP OUT OF REACH OF CHILDREN.
