ProMasonry Sand Mix is a blend of Portland cement and sand, designed for professional use. All ProMasonry products are processed through precision blending equipment to ensure a consistent product of superior quality.
High strength mortar, high strength grout, patching, repairing, stuccoing, or other general concrete applications where a thickness of less than 2 inches is required.
Remove all loose and/or deteriorated material as well as any surface contaminants such as oil, paint, grease, etc.
Empty the contents of the bag into a clean wheelbarrow, mortar box, mechanical mixer or other mixing vessel. Form a crater with a shovel or hoe in the center of the dry mix. Pour the recommended 4.25 quarts (4.0 L) of clean potable water into the crater.
An excessive amount of water will weaken the mix and can result in cracking. Add small quantities, 1 pint (0.5 L) or less, of water and thoroughly mix to reduce stiffness.
For hand mixing
Blend dry mix with a shovel or hoe from the outer edges working the material towards the center. Continue mixing until all free water is used and all the aggregate is uniformly coated with cement.
For mechanical mixing
Mix the material for three minutes.
Areas to be patched should be chipped off to a depth of at least 1 inch (0 mm). Edges should be perpendicular and not feathered. Patch and surrounding area should be wetted although no pooled water should remain when ProMasonry Sand Mix is applied.
The patch should be screeded level with a straight edge held slightly above the unpatched area and then allowed to cure for 1 to 2 hours before being troweled to its final plane.
Overworking could weaken the surface and result in cracking, dusting or scaling.
Dampen with a fine mist of water for 24 hours or moist cure with wet burlap and polyethylene. Alternatively, apply ProMasonry Cure & Seal. Protect from direct sunlight, wind, rain and frost during the curing period.
Clean tools and equipment with water immediately after use. Cured material will need to be mechanically removed.
