Concrete bonding agents: why you need them, how to choose
Why you need to use a concrete bonding agent. The cement within a concrete mix doesn’t contain any natural bonding agents – so when fresh concrete is added on top of an existing layer of concrete, the two won’t join together. Once cured, the new concrete will simply sit on top as a separate layer.Learn More
