Your brick columns serve the purpose of supporting the rest of your brick wall. Brick also adds warm, red color and a lot of charm to a garden. The top of a brick column, especially one that is attached to a low retaining wall or garden wall is often left unfinished, with just the brick as the decorative element. Adding a capstone to the brick wall is simple, easy and inexpensive, especially if you make the capstone yourself. Buy concrete forms from an online retailer or from a mason.
Things You'll Need
- Concrete mold
- Cooking oil
- Pre-mix concrete
- 5-gallon paint bucket
- Small bucket
- Plastic tarp
- Putty knife
- Concrete sealant
Place the capstone molds on a level work surface. Spread cooking oil on the inside of the mold with a clean rag. This will keep the concrete from sticking to the mold.
Put pre-mixed concrete and water in a large bucket according to the suggested ratios on the packaging. Stir to combine. The mixture will be as thick as oatmeal.
Use a small bucket to scoop out the concrete and pour it into the mold until the mold is full. Shake the mold to level the concrete and eliminate air pockets.
Skim the top of the damp concrete with the flat side of trowel to create a smooth surface. Let the concrete cure for 48 hours.
Pick up the mold, turn it over and shake gently until the concrete slides out.
Place the concrete caps outside under a tarp for seven days. Once cured, brush the capstones with a thin layer of concrete sealer.
Tips & Warnings
- Add concrete colorant to the mixture when you mix the concrete and water to customize the shade of the capstone. Colorant is available in powder or liquid. Follow the instructions on the colorant to determine the amount to add to the concrete mixture.
