Next, we'll move the concrete "mud" to get everything level and to release all of the air-pockets that may have been trapped during the pouring process. At this time the actual shape of the forms will yield the final dimensions of the concrete. Curved concrete forms are only different in that they can be "bent" on a radius to create curves.
At this point, the edges of the concrete (those closest to the forms) are finished with a special angled trowel which brings out a nice radiused curved concrete edge.
The set time on the concrete can vary depending on a multitude of variables present during the pour. Rain, hot weather, and the depth of the pour can all affect how long it takes before the
decorative finish can be applied . Under most circumstances etching and supplemental "color patina" surfacing can be applied after the concrete has cured to a relative set. Using a release powder to keep the concrete from sticking to the mat, and choosing the right time to use the concrete stamping mats are very important in acheiving the desired effect.
Using different concrete stamp designs may involve a random mat placement (creating an antiqued cracked finish) or a more ordered movement (brick, slate, and other repetitive styles).
