Commercial-Grade Concrete Patch
CPM is a high-strength, rapid-developing, commercial-grade concrete patch that forms a very dense patch that will resist chlorides and acids.
Features
- Low chloride permeability
- High freeze-thaw resistance
- High compressive and shear/bond strengths
- No bonding agent needed
Uses
Specially designed for patching, repair and restoration of worn or damaged concrete structures and surfaces such as:
- Curbs
- Sidewalks
- Pools
- Foundations
- Buildings
- Slabs
|
- Roads
- Bridge Decks
- Spillways
- Driveways
- Ornamental Casts

Coverage
One 5-gallon pail will cover approximately 16 square feet at a thickness of 1/4 inch.
Directions
 |
| Roughen the edges for proper adherence and remove all loose debris. If area has grease or oil build up use brush with detergent and water to clean. Flush with water to eliminate any detergent residue. Allow area to remain damp but with no puddles. |
|
 |
 |
| Add 5 parts of dry mix to 1 part clean water and mix thoroughly. The mix will appear dry at first, but will “moisten” as mixing continues. If the initial set starts, DO NOT add more water and try to remix or retemper, as this will result in loss of strength. |
|
 |
Note: CPM requires much less water
than other concrete products.
 |
| Place mixed material in the dampened area to be patched. Work material into the old concrete and trowel finish. |
|
 |
 |
| For best results, after the initial set has taken place, the surface may be moistened and troweled to a smooth finish. If repair is deeper than 6” apply in 2 equal layers waitng 30 minutes between applications. |

Safety
Wear protective clothing (gloves and safety glasses) as direct contact may irritate eyes and skin. Wash exposed areas promptly with water. If any material gets into the eyes, rinse immediately and contact a physician.
