What's the Deal with the Stamps?


What’s the Deal with the Stamps?

The patterns are made using large, flexible polyurethane stamps. The stamps are about 2-by-2-feet square and an inch or two thick, and they’re pressed into the wet concrete to create the textured finish. 

A concrete contractor may step on the stamps to press them into the concrete or use a tamping tool. Before putting the stamp on the concrete, the contractor sprays the patterned side of the stamp with a release agent that prevents concrete from sticking to it. 

Using a colored release agent accents cracks and grout lines, giving the finish an “antique” look that enhances realism.

One pattern usually is a set that includes several stamps, each one with varying textures and shapes, so the overall pattern isn’t repeated too frequently. Stamps also have interlocking tabs so any grout lines align perfectly.
