Concrete stamping is a way to press images into wet concrete and permanently decorate the surface before the concrete is able to dry or cure. Concrete stamps are sold in many different designs, but creating your own stamp can be done by making a mould or cast of the design that you wish to stamp into the top of the concretes surface. You can use an object with a design that you like or choose to create your own by pressing your fingers or hands in the polymer mould.
- Skill level:
Things you need
- Polymer clay
- Plastic box
- Object to be stamped
- Mold release agent
- Silicone rubber mould mix
Mold a two-inch layer of polymer clay into the bottom of the plastic box and form walls up the side of the plastic box that measure four inches high and two inches thick.
Spray the object that you want stamped into the clay with mould release agent if you have chosen one. Be sure to cover the entire surface of the object. The mould release will form a seal over the object to separate the object from sticking to the clay for a smooth and clear impression left in the polymer clay.
Press the object you have chosen for a design into the bed of clay. Press the object an inch deep into the clay. You can also create your own design by using your fingers or multiple objects for a unique design.
Spray the inside of the plastic box where you have moulded the polymer clay with mould release agent.
Mix and pour the silicone into the box on top of the polymer clay, one inch thick. Begin in a corner and apply evenly over the entire surface. Tap or gently shake the sides of the plastic box to level the mixture and remove any air bubbles that may have formed.
Allow the silicone to dry completely and remove the created mould from the plastic box. Press into the concrete surface.
