Preparing the Outer Planter Mold

The first step in this DIY concrete planter staining tutorial is to prepare the outer planter mold. This involves cutting the bottom of a plastic pot off using a utility knife. The plastic pot will serve as the outer mold for your concrete planter. Once the bottom is removed, you can trim it to make the opening wider for easier casting of the cement. To hold the molds in place, you will need to create a base using a flat board and an acetate sheet.

Cutting the Cardboard Tube and Securing the Inner Mold

In this section of the DIY concrete planter staining tutorial, we will focus on cutting the cardboard tube to size for the inner mold of your concrete planter and securing it in place. Follow the steps below to ensure a successful outcome:

  1. Measure and mark the cardboard tube at a height of 3 1/2 inches.
  2. Using a utility knife and a homemade flashing straightedge, carefully trim the tube to the marked height.
  3. Once the inner mold is cut to size, secure it to the base using hot glue. Apply the hot glue around the bottom perimeter of the tube and firmly press it onto the base.
  4. Prepare damp sand and fill the cardboard tube with it, packing it down firmly to level it with the top.
  5. To prevent the concrete from escaping during pouring, glue an acetate circle to the top of the cardboard tube.

By following these steps, you will have a secure and well-sized inner mold ready for pouring the concrete for your DIY concrete planter.

Securing the Outer Concrete Planter Mold

After securing the inner mold, it’s time to move on to securing the outer concrete planter mold. This step is crucial in ensuring that the mold remains stable during the pouring and curing process.

To secure the outer mold, I recommend using hot glue. It is a quick and effective method that provides a strong bond. Apply hot glue along the larger circle on the base, ensuring that the glue line is on the outside of the mold. This will prevent any visible glue marks on the finished planter.

Once the outer mold is attached to the base, double-check that it is firmly secured in place. This will ensure that the mold doesn’t shift or move during the pouring of the concrete.

By securing the outer concrete planter mold, you can proceed with confidence to the next steps of the DIY concrete planter staining tutorial.

Making a Drainage Hole for the Planter

To provide proper drainage for your DIY concrete planter, you will need to create a drainage hole. Follow these steps:

  1. Use a heat tool to burn a hole in the center of the acetate on the base. Make it wide enough to fit the jumbo straw inside.
  2. Trim the straw to a few inches and insert it into the hole, protruding about an inch above the acetate.
  3. Close off the top of the straw with tape to prevent the concrete mix from getting inside.

Mixing and Casting the Concrete

Now it’s time to mix and cast the concrete for your planter. Follow the instructions on the bag of white mortar mix (or gray/beige mix) to mix it with water. The consistency should be like a mud pie for the white mortar mix. Scoop the mixed concrete into the crevasse of the two molds and fill it to the top. Vibrate the concrete mold well to remove air bubbles. Let it cure for 24 hours before demolding.

Once you have your concrete mix ready, carefully pour it into the molds. Start with the outer mold, ensuring that the concrete fills up to the top. Use a spoon or stick to help maneuver the concrete mixture and fill any gaps or corners. Then, proceed to pour concrete into the inner mold, making sure it is also filled to the top.

After pouring the concrete, gently tap and vibrate the molds to remove any trapped air bubbles. This will help ensure a smooth and solid finish for your planter. You can use a vibrating tool or simply tap the sides of the molds with a rubber mallet.

Tip: If using a vibrating tool, be cautious not to overdo it as excessive vibration may cause the concrete to separate and weaken.

Allow the concrete to cure for a minimum of 24 hours. Curing time may vary depending on the type of concrete mix used, so be sure to check the instructions on the bag. During this period, it’s important to keep the molds undisturbed and in a cool, dry place.

Note: Proper curing is essential for the strength and durability of your concrete planter. Rushing the curing process may result in weaker final results.

Demolding and Staining the Concrete Planter

After allowing your DIY concrete planter to cure for 24 hours, it’s time to demold and add the finishing touch of stain. Carefully remove the straw from the drainage hole and peel off the acetate on the base. Empty out the sand from the inner mold, and then gently shake or use a heat gun to demold the planter. Take your time to ensure a clean release.

Once demolded, you may notice some rough edges on the planter. To smooth them out, use a #200 grit diamond sponge to sand the edges. Additionally, refine the inside edges with #220 grit sandpaper to give the planter a clean finish.

Next, prepare the wood stain by thoroughly mixing it. To apply the stain, use a foam brush or sponge and cover the sides of the planter evenly. Be sure to reach all areas of the exterior surface. After applying the stain, use a staining rag to wipe off any excess product and achieve your desired color. If you prefer a darker shade, you can repeat the staining process. Remember to stain the top rim and a few inches inside the planter for a cohesive look.

By following this DIY staining tutorial, you can successfully demold and add vibrant color to your concrete planter. This final step will bring your creation to life and make it a standout feature in your garden or outdoor space.
