[18   x 18   Stamp]

How to stamp concrete? After applying a powder or liquid release agent to concrete, lay stamp on concrete surface and press into the concrete. Walking on the stamp, or (depending on concrete hardness) an Tamper Tool may be needed to help push the stamp into the concrete. When picking up the stamp, grab the edges on both sides and pick straight up. Make sure to not drag the stamp across the concrete surface. Turn the stamp at different angles each time you place it down so the pattern is unique. Use multiple stamps to be able to walk out onto the concrete- standing on one while you pick up and re-position the other. Try not to press the edges of the stamp into the concrete. If you do, it will leave a mark that will look like the edge of a stamp, instead of looking like the stone texture... Stay away from the outer few inches of the stamps when walking or tamping them down into the concrete, and when placing the next stamp (if you are using multiple stamp mats), overlap the stamps about 6", and pick up the edge of the stamp you are standing on so the new stamp mat goes underneath it, and then move over onto the new stamp mat and continue the stamping process. Once the concrete is set (usually the following day), any release powder can be washed off with a hose. More release can be removed as needed, either by using a broom to help remove it, or pressure washer. Once you remove enough release agent coloring from the concrete to satisfy the look you are after, let the concrete finish curing (usually 4 weeks) before you seal the concrete.
