Q: What is stamped concrete?
A: Stamped concrete is when concrete is still in a soft, plastic stage. A rubber imprinting mat is used to leave an impression of slate, rock, brick, cobblestone and more.
Q: What is stenciled concrete?
A: Stenciled concrete is when a paper stencil is pressed into the surface of the concrete and a color hardener is applied to the surface. If you desire a textured look, a liquid or powder release is used along with a textured roller to leave a texture behind. A flat finish is also possible. Once the concrete has hardened some, the paper stencil is removed leaving behind distinct grout lines.
Q: How many stamps do I need?
A: It can depend on the pattern, but a full row across with 2 to 3 coming back is recommended.
Q: How much can I pour at one time?
A: It depends on crew size, experience and weather conditions. However, a 3-4 man crew can do about 300-400 square feet.
Q: How is color applied?
A: The two most common methods are:
- Integral – Which is when color is added to the load in the truck, coloring the entire load.
- Color Hardeners – Which are broadcast over the surface of freshly poured concrete coloring only the surface.
Q: How do I keep concrete from sticking to the stamps?
A: A liquid or powder release agent is used.
Q: When do I begin stamping?
A: You should wait until all the bleed water has evaporated and the concrete is firm enough to only leave ¼” deep foot prints. Again crew size, experience and weather conditions need to be considered.
Q: How are different shades achieved?
A: A method called antiquing is used to highlight the impressions of the stamped concrete. You can use liquid antiquing or powdered release agents to achieve the highlights.
Q: Can I stamp steps?
A: Yes. You use textured touch up mats, rollers or chisels to create the desired look.
Q: Will decorative concrete crack?
A: Yes. Decorative concrete is still concrete. Saw cuts and control joints are still needed.
Q: Should I cure and seal decorative concrete?
A: Again, decorative concrete is still concrete. You should always cure and seal concrete.
Q: Is the sealer permanent?
A: No. Concrete will need to be resealed. Weather and use will determine how often concrete will need to be sealed.
