Foam clay is a versatile and popular crafting material that can be used to create various types of projects, including sculptures, jewelry, and decorations. It is made from non-toxic foam particles mixed with glue and colorants, which makes it easy to mold into any desired shape. However, one common challenge when working with foam clay is how to seal it properly.
Sealing foam clay is essential for preserving the shape and color of your project, as well as protecting it from moisture or damage. In this guide, we will discuss some methods and tips on how to seal foam clay effectively. So, let’s get started!
Why Seal Foam Clay?
Before we dive into the sealing techniques, it is important to understand why sealing foam clay is necessary.
