FAQs

What does curing do to my concrete? 

Curing involves keeping the freshly poured concrete moist for a short period of time (usually 3-7 days). By keeping the concrete moist, it allows the bond holding the aggregates and paste to get stronger. If left to dry out, concrete doesn’t harden properly, so it is best to begin curing just after finishing the concrete surface.

By curing your concrete it is stronger and more durable, while being less prone to cracking.

How can I remove stains from my concrete?

Everyday stains caused from grime can be removed by washing and scrubbing, and even washing with a water jet in some cases.

Other stains such as oil, rust or paint, can penetrate into the concrete surface and be hard to remove. These kinds of stains may be removed with special chemical stain removers. Others may be covered with concrete paint.
