How to Make Concrete Caps

It's easy to make decorative concrete caps. They make a great addition for the tops of retaining walls, and add stylish touches to your property. Concrete caps may be purchased at a home improvement store in your town. But it's much cheaper to just make it yourself. Increase your home's aesthetic value by attaching the concrete caps atop of any exterior walls on your property.

Instructions

    • 1

      Place the cap's concrete molds on a level surface. Moisten the rag with cooking oil. Evenly spread the rag inside of the molds. This will protect the concrete and stop it from sticking.

      Put water into the pre-mixed concrete. Use the ratios for measuring that are printed on the side of the package. Remove a single cup of concrete with the bucket at a time. Put the concrete carefully into the molds. Shake them gently in order to settle the molds of concrete. Do this until each of the molds are at their capacity.

      Use the trowel's flat side to level the molds. This will make a smooth surface over the concrete. Allow the concrete to sit for 50 hours. Place a towel on your work area. Turn over each mold individually. Rotate the mods gently until the caps slip out.

      Put a tarp over the caps. Allow them to sit for eight days. Use the brush to place a layer of sealer on both sides of the pavers.
