How to Stamp Concrete
Stamping concrete is an economical way to decorate the surfaces of concrete without having to use tiles, paint or any conventional method of decorating. You can save even more money by stamping the concrete yourself. Here’s how to do it.
Regardless of whether you’re pouring new concrete or removing old pavements to make way for a new one, plan your layout carefully. Decide on the color, pattern how you will lay out your mats later on.
When it comes to patterns, long lines should run perpendicular to the length of the concrete area. Make a trial run with the mats before you even lay down the concrete.
Use a sub-grade and concrete base that meets the requirements for stamped concrete. Use admixtures that do not contain calcium chloride as this may affect the color and how the concrete will set.
Mix and pour the concrete in the designated area. You can read on more about it in How to Mix Concrete and How to Pour Concrete. Don’t make the concrete any thicker than four inches.
Coloring the concrete is another way to make the stamp concrete look more interesting. It will also improve on its texture. You can use Liquid Color that’s already mixed in the mix truck. The Broadcast Method is done by applying color hardener directly in the freshly-poured concrete surface. Do the Broadcast Method by spreading the powder in wide, sweeping movements.
Apply the color release agent. It will prevent the texture mats from sticking on the concrete later on. You should apply the color release agent when the concrete is about the reach the optimum set for stamping or texturing. It usually takes around 3.5 pounds of color release agent for every 100 square feet of concrete. Brush the agent across the mats uniformly. Choose a color release agent that will complement the concrete’s color.
Lay down the mats. You may need assistance on this one. Keep in mind that excessive force is not required, but timing is important. Work quickly once you’ve begun on stamping.
Place the texture mats carefully, tightly, aligning them precisely and stamped all in the same together. Tamp the mats straight down, with just enough strength.
After tamping, carefully peel off the mats from one side first.
After letting the concrete set for 24 hours, use a high-power pressure washer to spray on the surface. Use this to remove the excess release agent. Be careful with using this, as it may cause damage to the concrete.
Seal the concrete with a decorative concrete sealer. Follow the instructions when applying a light coat. A gallon should be able to easily cover 200 square feet.
