Questions about this item

Does the 6000 psi concrete generate noticeable heat while it cures over a full day?

The mix reaches full cure in 1 hour and is designed for patch and repair work, so any heat produced during curing is brief and not sustained over an entire day.

What tools or supplies must I already have to use this 60 lb pail of concrete mix?

You will need clean water, a mixing container, and a mixing tool such as a drill with a paddle attachment or a hoe, plus standard finishing tools like a trowel or float.

Will this gray concrete mix bond reliably to the older concrete slab I plan to patch?

Yes, it is formulated for patch and repair on concrete surfaces and achieves 6000 psi yield strength when applied between 45 and 70 °F with a 15-minute working time.
