How do you get started with polymer plaster?

Polymer gypsum is a versatile material that is ideal for creating decorative and functional objects. Its durability, aesthetics and ease of working make it a popular choice for professionals and amateurs alike. Here is a practical guide on how to get started with this material.

Choosing the right polymer gypsum

You will find different types of polymer plaster on the market. Choose the one that suits your needs - whether for precise decoration or more functional projects. Pay attention to properties such as strength, moisture resistance or setting time.

Preparation of tools and accessories

You will find it useful to work with polymer plaster:

• Silicone moulds - in various shapes and sizes, ideal for casting.
• Dyes - allow any colour to be obtained.
• Lacquers - protect and give a finish.
• Mixing tools - spatulas or mechanical stirrers to evenly combine the ingredients.

Preparation of the polymer gypsum mixture

The method of preparation depends on the product chosen. In most cases, the proportions of gypsum and water or resin/powder mixture should be measured accurately. It is crucial to mix thoroughly to get a uniform consistency. If you want to add colour to your project, add pigment to the mix. It is important not to exceed the recommended proportions so as not to adversely affect the properties of the material.

Once the mixture is prepared, pour it into the silicone mould. To avoid air bubbles, gently tap the mould against the work surface or use a vibrating table.

The setting time depends on the type of gypsum - it usually takes between 30 and 40 minutes. After this time, you can carefully remove the cast from the mould. However, it is worth leaving it for longer so that the material hardens completely.

Treatment and finishing of a polymer gypsum casting

After removal from the mould, the casting should dry for the time indicated by the manufacturer polymeric gypsum. It can then be sanded, painted or varnished, depending on the intended effect. The finished product is worth impregnating to increase its durability and resistance to moisture.

Following these steps will allow you to enjoy working with polymer plaster and create long-lasting, aesthetically pleasing decorations that will please the eye for years to come.
