Building the Formwork
Creating a sturdy mold is critical for achieving a flawless bench. Here’s how to build formwork for your concrete bench:
Creating the Mold
-
Cut your plywood or melamine boards to the desired dimensions. You will need pieces for the top, sides, and possibly a bottom, depending on your design.
-
Assemble the boards into a rectangular box using screws or nails, ensuring there are no gaps where the concrete can leak. If you’re creating a bench with a backrest or arms, modify the mold accordingly.
-
Apply a release agent to the interior of the mold. This ensures that your concrete can be easily removed once it has cured.
Assembling Reinforcement
To enhance the strength of your bench, it’s essential to add some reinforcement. Here are some steps to incorporate rebar or wire mesh:
-
Cut your rebar into appropriate lengths for the width and length of your mold.
-
Lay the rebar in a grid pattern, approximately every two feet, ensuring it is raised slightly off the bottom of the mold to be embedded in the middle of the concrete.
-
If using wire mesh, cut it to fit within the mold and place it above the rebar.
Mixing the Concrete
Now that your form is set, it’s time to mix the concrete. Follow these steps:
-
In a mixing container, combine the dry concrete mix with water according to the manufacturer’s instructions. Aim for a consistency similar to thick pancake batter.

Mix well using a shovel or hoe, ensuring there are no dry patches or lumps. If desired, you can add colorants to the mix for a unique finish.
Pouring Concrete into the Form
With your concrete mixed, proceed to pour it into the mold:
-
Begin pouring the concrete into the form. It’s essential to do this in layers, filling about one-third of the mold at a time.
-
As you pour, use a trowel to spread the concrete evenly and eliminate air pockets. This step is crucial for ensuring a solid bench.
-
After filling the form, use a float to smooth the surface. This will enhance the aesthetics and prepare it for finishing.
Finishing Touches
Once the mold is filled, it’s time to prepare for curing and finishing:
Curing the Concrete
Allow the concrete to cure properly; this usually takes about 24 to 48 hours. During this time, it’s essential to keep the surface moist to prevent cracks. You can achieve this by covering the mold with plastic wrap or burlap and misting it occasionally with water.
Removing the Mold
After the curing period, gently remove the mold. Be careful not to chip or damage the edges of your bench. If you used a release agent effectively, the mold should come off easily.
Sanding and Sealing
-
If necessary, use sandpaper or a grinder to smooth any rough edges or surface imperfections.
-
To protect your bench and enhance its appearance, apply a concrete sealer. This will also make it resistant to stains caused by moisture or spills.
Adding Personal Touches
Now that your concrete bench is taking shape, consider adding personalized touches. These might include:
- Paint or Staining: You can use concrete stain or exterior paint to add color and patterns to your bench.
- Decorative Elements: Incorporate decorative tiles, pebbles, or glass pieces into the surface for a unique look.

Placement of Your Concrete Garden Bench
Choosing the perfect spot for your new concrete garden bench is essential for maximizing its beauty and utility:
Strategic Location
Place your bench where it can enjoy the beautiful views of your garden, ideally near flowering plants or a water feature.
Sun and Shade
Consider the sun exposure in different seasons. If your bench will be positioned in a sunny area, think about providing shade through surrounding trees or awnings.
Maintaining Your Concrete Bench
After you’ve built and placed your bench, keeping it in good condition is crucial:
- Regular Cleaning: Use a soft brush or cloth and mild detergent to clean the surface. Avoid harsh chemicals, as they can damage the concrete finish.
- Periodic Sealing: Depending on the conditions it endures, reapplying a sealant every few years can protect against wear and stains.
