Concrete has its own charm and has long been introduced into our apartments and gardens in the form of fancy home accessories. DIY projects with concrete are also very suitable for beginners, because with a few steps you can get great results here.
Today we would like to recommend you a manual for concrete planters. In just six steps, you can make unique plant pots in every shape and size. You can even add decorative shells or broken glass for beautiful effects. Whether you want to make small pots for cacti or very large pots for the garden - with our DIY guide crafting is guaranteed fun.
Before you start, you only need:
- Concrete screed (from the hardware store or online shop)
- Kitchen or work gloves
- Paraffin oil or other lubricant
- Molds or cardboard & Scissors for making molds
- a bucket or a wheelbarrow for mixing
- if necessary broken glass, glass beads, shells, pebbles
- Plastic wrap or plastic bag
Everything together? Here we go!
1. Select the casting mold
For the production of your planter you first need an outer and an inner mold. Both should have the same shape but be different in size. The smaller shape should fit into the larger shape, leaving about 5 cm of space between both shapes. This space will later be filled with concrete to determine the thickness of your planter. If you want to make a particularly large planter with dimensions greater than 60 cm in height and width, make sure that the thickness of the tub is at least 7.5 cm.
You can make molds yourself, for example by making two boxes from cardboard. So you can decide for yourself which size and shape the molds should have. The material for the forms is glass, plastic, cardboard, stainless steel or polystyrene.
2. Prepare the insides of the molds
The inside of the molds, which will come in contact with the concrete, you should sprinkle with some paraffin oil, sunflower oil or lubricant. This will make it easier for you to remove the concrete bucket from the mold later. If you use a glass mold, then you can also avoid that the glass breaks when you solve the bucket from the mold.
Maybe you would like to use several molds for your DIY project. Try different shapes and sizes. DIY-style planters are great in the garden, in the home, and are also a nice, home-made gift for friends and relatives!
3. Mix concrete
Your hands should be protected when mixing the concrete with a few good kitchen or work gloves. Mix the concrete mass in a bucket or in a wheelbarrow. It's best to use high-strength concrete. Put the concrete in the bucket or the wheelbarrow and gradually add the water with constant stirring. Be sure to observe the necessary mixing ratio, you will find it on the packaging of your concrete mix.
For concrete mix you can also add broken glass, stones, shells, pearls or other decorative materials. This conjures up beautiful effects on the planter. Just make sure that the consistency of the concrete remains the same overall.
4. Pour concrete into the mold
Now you start casting the concrete: you should pour the concrete mixture slowly and evenly on the bottom of the outer mold, so the bottom of the bucket is made. For example, if your planter is to have holes for drainage, you can now pebble into the ground, or you can drill a few holes later - but wait at least two days after the concrete dries.
Smooth the concrete with a spatula or a trowel and now place the inner mold on the concrete mixture. Push it on the concrete until you reach the thickness your planter should have. The bottom and walls of the vessel should be approximately the same thickness. The floor may be a bit thicker than the walls, but to keep your planter stable, it should not be the other way around!
Now the remaining concrete is poured between the two forms. Keep pausing time and again to squeeze the mixture with a spatula or trowel and avoid the formation of air bubbles. If you have poured the top of the bucket, then smooth the mass once more with the spatula.
5. Let stand
Now you need a little patience, because first the bucket with molds carefully wrapped in a plastic sheet or a plastic bag and left for about 36 hours. Also take note of the times on the packaging of your concrete.
Then you test with a knife or corkscrew, if the concrete is already dry enough. If you can dig into the bucket, the concrete is still too wet and needs to be left standing longer.
6. Remove the planter from the mold
When the concrete is dry, slowly loosen your planter from the mold. You can also easily remove a cardboard mold from the bucket. With sandpaper, you can sand and smooth the surface.
Now the bucket should be left to dry thoroughly for a full week. Once a day, you should rub the plant pot with a wet sponge or cloth until the color darkens. Now, even if the tub has dried for more than two days, you can drill holes for drainage.
