The American Concrete Institute recommends a maintained temperature of 70 degrees F for three days or 50 degrees F for five days to gain sufficient strength for a cold pour to perform up to specification.
The first thing to do is clean the concrete surface thoroughly. It should be free from dust, dirt, grime and grease. The surface should also be dry. For the best results, apply the adhesive onto the concrete when the temperature is between 65Â°F and 95Â°F. If the concrete is too hot or too cold, the adhesive will not be as efficient. Read and follow the adhesive manufacturerâs instructions carefully to make sure that you get the best bond between your two surfaces. Then apply the adhesive evenly onto one surface only, using a notched trowel.
