Will concrete bond to existing concrete?
Concrete doesn’t have any natural bonding agents or adhesive. For this reason, concrete on its own won’t bond or stick well on another concrete material. When you put concrete on top of another concrete layer, it’ll sit there as an independent layer without joining. It won’t produce a strong or serviceable floor.
How do you make a concrete bonding slurry?
The ratio for a basic concrete slurry mix is 1 or 2 parts Portland cement to 1 part water. Start with equal parts cement and water, and then add more cement until you have the desired consistency.
