How to make a silicone mold for casting concrete products

Concrete products — planters, candlesticks, decorative elements — are at the peak of popularity today. Their brutal aesthetics and texture attract many. And the most interesting thing is that many of these things can be made with your own hands. The key element for this is a high—quality casting mold. And although ready-made molds can be bought, it is much more exciting to create your own unique silicone mold.
The silicone mold allows you to accurately copy almost any object, transferring all the smallest details of its surface. Working with silicone is not as difficult as it might seem at first glance. The main thing is accuracy and compliance with technology.
Preparation of the master model and formwork
The first thing we need is a "master model", that is, the very object that we want to copy. It can be anything: a beautiful vase, a statuette, a wooden block of interesting shape. It is important that the surface of the master model is smooth and non-porous. Porous materials (wood, gypsum) must be pre-varnished.
Next, for the master model, we need to create a formwork container into which we will pour silicone. The formwork can be made from anything: plastic, cardboard, plywood, Lego parts. The main thing is that it should be airtight and there should be a gap of 1-2 centimeters on all sides between the walls of the formwork and the master model. The master model must be securely glued to the bottom of the formwork.
Selecting and kneading silicone
Silicones for molds are different, but two-component formulations based on tin or platinum are best suited for beginners. They consist of a base (component A) and a hardener (component B). Platinum silicones are of higher quality and more durable, but also more expensive and capricious in operation.
Please read the instructions carefully before mixing. Usually the components are mixed in a certain proportion (for example, 100:2) by weight, so you can't do without kitchen scales. Mix thoroughly, but not too intensively, so as not to add excess air bubbles to the mixture.
Filling and degassing
This is the most crucial stage. The finished mixture should be slowly and carefully poured into the formwork. You need to pour at one point, in a thin stream, so that the silicone fills the entire space by itself. This helps to avoid the formation of air pockets.
Ideally, after mixing, the silicone should be degassed in a vacuum chamber to remove all air bubbles. But there is usually no such camera at home. Therefore, you can simply gently tap the formwork several times from all sides. This will help the large bubbles rise to the surface.
After pouring, the silicone should be given time to polymerize (solidify). This time is specified in the instructions and can range from several hours to a day. You shouldn't touch him or rush him. When the silicone is completely frozen, the formwork can be disassembled, and the master model can be carefully removed. Your unique form is ready to work.
