Step-by-step: create decorative objects in aerated concrete for your planters

Aerated concrete, also called "Siporex", is a soft and easy-to-work material for anyone wishing to take their first steps in sculpture. Tender certainly, this material is nevertheless suitable for outdoors where your creations will take on a patina over time. This is what recommends this material for decorative objects, intended or not for your outdoor planters! Easy to work, aerated concrete is also inexpensive. Its main and almost only constraints are that it breaks easily and that it is not suitable for making fine details. Let's just remember that it is the complexity of the subject that will determine the level of difficulty of an achievement. Thus, the more these will present fine and detailed parts and the more the work will require caution in handling to avoid breaking the part during production. To start, here we suggest you make small objects with simple contours and inspired by nature. But in terms of creation, all the fantasy is allowed so do not hesitate, once the material is tamed, to give free rein to your imagination! Difficulty : very easy example, if not depending on the complexity of the subject (delicate and messy work) Cost : around 5 euros Tools required : - A block of aerated concrete (thickness to choose according to your project) - Graters - A handsaw - A screwdriver Optional: - Sandpaper - Gouges - A knife - A hammer, points and chisels for producing precise or in-depth details

Step 1: Cut a block corresponding to the overall volume of your project

Using the handsaw, cut a piece from the aerated concrete block corresponding to the overall volume of your project.
Here we use a 10 cm thick block from which we are going to cut a 10 cm wide "slice".
Make a second cut to have the volume you need to register your shape.

Step 2: Draw the contours of your project

We plan to make a mushroom that has a rounded shape and without major difficulty. Make a first outline of the object's contours on paper and then, using a pencil, transfer them to the block. Do not hesitate, if it makes you more comfortable, to cut your drawing to more easily redraw the contours on aerated concrete.
Define your shape on paper first…
… Then transfer it to the aerated concrete block.

Step 3: Trim the shape

By attaching to the previously drawn contours, rough out the shape of your project. Be careful, even at this stage, to handle the object with delicacy, because cellular concrete breaks easily. This is why we chose a robust object for this first realization.
Use the handsaw for this job.
As much as possible with a saw, it is as much gained on work - longer and meticulous - by means of the grater or gouges.
To help you in the rest of the work on the volume, reproduce your shape on each of the 4 sides of the block.
For your comfort, keep your workspace clean.

Step 4: Refine the shape

Once the shape is rough, use finer tools (rasps, knife ...) to get closer to the final contours.
Vary the rasps according to the work you have to do: a flat model will be perfect for treating the underside of the hat, a round model will be more suitable for treating the volume of the foot.
The volume of the hat is given.
Continue by attacking the foot.
The mushroom begins to take its final form!

Step 5: Apply the final touches

Once the general shape obtained, place the finishes! Here we suggest digging the underside of the hat slightly or using a gouge or a knife to give it more relief.
Use a gouge, knife or any tool you feel comfortable with!
Also take advantage of this step to perfect the shape of the hat and the foot.
It's finish ! In your momentum, you just have to grab another block for a more abundant harvest!

Step 6: Set up your decorations


All you have to do is find the best location for your pair of boletes. Will they grow at the foot of the lemon tree or that of the yucca? No, it is ultimately in a pretty composition of succulents that they chose to take up residence.
