CONCRETE REPAIR 

Q: What product is best to use for a spalled walkway or garage floor?
A:
ProSpec Concrete Resurfacer is designed for applications ½” down to a featheredge and is polymer modified so it will bond well to old properly prepared concrete. It is fast drying and is walkable in 2 hours.

Q: What is SSD?
A:
Saturated Surface Dry. Most portland cement based repair materials require the concrete to be in a saturated surface dry condition prior to the application of repair material to prevent a loss of water from the repair material and absorbed into the substrate. This is achieved when the concrete substrate is saturated with water and there is no standing water on the surface.

Q: What are the benefits of using an air entrained concrete mix like the Metro Mix 240AE?
A:
When using an air entrained concrete mix you will notice an increase in the material’s workability and improved freeze/thaw resistance. When water freezes it expands and takes up more space than water. The air content in an air entrained mix will be higher than a traditional concrete. This higher air content will allow the freezing water to migrate into the intentional air voids without causing damage to the concrete.

Q: Can ProSpec Concrete Resurfacer be stained or pigmented?
A:
Yes, you can add pigment to the CR to achieve a specific color or it can be stained once it has been allowed to cure the recommended amount of time. The cure time prior to staining will be determined by the manufacturer of the stain.
