Introduction: Sunflower Style Concrete Planter

Concrete is such a nice material to mold with that anyone can fall in love with it.

This mother's day, I decided to make something and came up with this beautiful looking planter made of concrete.

And in this Instructable, I will guide you through the whole process of making the planter, so follow along.

Step 1: Gather the Supplies

  1. Silicon mold https://amzn.to/2L0BFXG
  2. Sand
  3. Portland cement or pre-mixed concrete mix https://amzn.to/2IMqAei
  4. Protective gloves
  5. Mold release agent https://amzn.to/2IoSDNO
  6. paint https://amzn.to/2L31TZy

That's it, now let's make it.

Step 2: Preparing the Mold

As we all know that silicon mold is quite flexible and concrete is heavy, so the silicon mold wont hold its shape when concrete is poured in it. The sides of mold needs to be reinforced. To do so, take the silicon mold of your choice and place it in a vessel, fill the vessel with sand and pack it down as shown in the images above.

Step 3: Preparing the Other Half of the Mold

We have Prepared the outer mold, but if we pour the concrete now, there won't be any place left for the plant itself (obviously). So we will need to make something which will help us to create the void where our plant will go.

Yo make this, take a sheet of styrofoam and draw circles with diameter about a centimeter less than that of the inner diameter of the silicon mold you are using. You will need to draw 5 to 6 circles depending upon the depth of mold and thickness of styrofoam sheet. (If your mold is not circular like mine then you should adjust the shape of the styrofoam cutout accordingly.)

Now cut them out and glue them together as shown in the image above.

Now take 80 grit sandpaper and smooth the edges, then proceed doing the same with 120 grit sandpaper.

Step 4: Preparing the Concrete Mix

To prepare the concrete mix, take 1 part sand and 1 part portland cement in a container. Mix it well then make a well in the mixture ( have a look at the video linked above) then pour some water in it. Let the cement-sand mixture absorb water then start mixing. The consistency should be of a thick pancake batter.

TIP: Let the mixture absorb water before you start to mix. It will make the mixing much easier.

Alternatively, if you buy pre-mixed concrete, follow the instructions on the packet.

Step 5: Applying Oil to the Mold

Before pouring the concrete, spray some mold release agent on the mold. This will help the planter form sticking to the mold.

I didn't have mold release spray, so I used mustard oil instead. You can use any oil.

Step 6: Pouring the Concrete

Before handling concrete, wear protective gloves, as cement is quite alkaline, which is not good for our skin.

First pour about a centimeter thick layer of concrete then place the styrofoam mold on it, making sure it is well centered. Then continue filling the sides with concrete. Once the mold is completely filled, put some weight on the styrofoam to stop it from floating.

Now leave it as it is for around 7 days, and make sure, the concrete does not go dry, as it will stop the process of hardening of concrete.

Step 7: Removing From Mold and Cleaning the Edges

After around 7 days, remove the silicon mold from the sand, then carefully peal off the silicon mold. Then take a sharp object like a screwdriver and remove all the styrofoam.

Now you will be left with a very rough looking concrete planter, to make it look nice, remove the excess concrete with a hack saw, then smooth the edges with 80 grit sandpaper followed by 120 grit sandpaper.

Step 8: Painting

This is the step which everyone loves. Yes, my friends, it's time to paint our creation. Paint it with any paint which can be painted on concrete and is water proof. I used yellow enamel paint to paint mine. (To make it look like a sunflower). You can be creative here and do whatever you want to.

Step 9: Planting a Plant and Admiring It

Now that your concrete planter is ready, plant a lovely plant in it.

Now you can admire your beautiful creation or you can give it to someone you love as a gift and let them admire it.

Anyway, If you have come to the end of this Instructable, Thank you very much for spending some time on my Instructable.
