Hammering Concrete
Before filing the gaps with epoxy, ensure that you have chosen the correct technique. Check out the concrete that needs repairs by using a sounding hammer before proceeding with the job.
Using Heat
The time taken by epoxy to cure can be affected by changes in the temperature. If you feel that the epoxy is curing slowly, apply gentle heat on the epoxy surface, which can be performed using a heat gun or a warming blanket.
Thinning the Epoxy
Having a thick filler would not bode well with the curing of the epoxy. Hence, it’s important to preheat the materials before mixing to thin out the epoxy, leading to faster curing time.
Shrinking and Moving Polymers
When two epoxy materials are mixed, this may lead to the polymers shrinking or expand when they cure. This is to be kept in mind, especially when dealing with larger cracks. It’s essential to understand the specifics of the product to understand the reaction of the polymer on a cure.
Understand the Width of the Crack
Before injecting the epoxy into the cracks, ensure you know the width and depth of the crack that needs to be filled. Measure the depth using a plastic crack card or a crack scope.
Keeping the Epoxy
If you have leftover epoxy left after the epoxy filling process, the unmixed portion can be stored safely in an airtight container. But due to the presence of polyurethane, ensure to use it as soon as you can.
Getting the Right Appearance
Once you have fixed the cracked concrete surface, you need to maintain its aesthetics. One can employ a sacking method that utilises hitting the wet surface of the concrete with a sack containing the same color of the concrete or use a paintbrush to paint over the concrete epoxy.
