What is thick EVA foam and what is it used for?

Thick EVA foam is a material composed of ethylene and vinyl acetate. Its high thickness makes it suitable for projects that require greater durability and strength. Because it is flexible, easy to mold and relatively inexpensive, it is an excellent choice for a variety of uses. In cosplay, for example, it is used to create armor, helmets, and accessories due to its ability to hold its shape once molded with heat.

This material is popular because it can be easily cut and glued, making it ideal not only for cosplay, but also for more robust crafts such as creating shoe soles, insoles, and even in toy making.

Thick EVA foam has become an essential material in the world of model making, crafts, and costume creation, thanks to its versatility, durability, and ease of handling. With a wide range of thicknesses and colors, this material offers endless options for those seeking quality and precision in their projects.

EVA (ethylene-vinyl acetate) is a foamed polymer characterized by its softness and flexibility. This version of the material stands out for its greater strength and rigidity, making it ideal for solid structures or for creating details in model-making and crafts.

Uses of thick EVA foam in model making and handicrafts

It is especially popular with modelers and hobbyists because of its unique properties that allow it to be easily cut, painted, and shaped. Here are some of its main uses:

  • Scenery for modeling. Ideal for creating terrains and bases in modeling projects. Provides a solid, lightweight base that can be sculpted and painted to fit any scenery.
  • Cosplay and costumes. Allows the creation of armor pieces, helmets, and other detailed accessories. Thanks to its thickness, it is possible to cut and mold this foam to achieve realistic finishes that can be painted or varnished.
  • Material for stamps and stencils. In the field of handicrafts, this material is used to create customized stencils and stamps. Its surface allows easy trimming with precision cutters or scissors, providing precise results.

One of the most interesting uses of it is the creation of scenery. This material allows the construction of elements such as rocks, walls, or bases for miniature figures. Its ease of painting and texturing makes it perfect for simulating natural materials such as stone or wood. In addition, it is much lighter than other options, which makes it easier to transport and store.

Advantages of using thick EVA foam

Choosing thick EVA foam over thinner options provides a number of benefits to cosplayers, crafters, and modelers:

  • Increased durability: This material resists wear and tear, better withstanding repeated modifications and offering a longer lifespan.
  • Support capacity: Due to its thickness, this version provides additional structural support, making it the ideal material for parts that need to stand or support weight.

What is the difference between thick and thin EVA foam?

The main difference between these two types is the thickness and the way it is used in projects. Thin EVA, which usually measures between 1 mm and 3 mm, with 2 mm being the most common thickness, is commonly used for more delicate details or for lining larger pieces. On the other hand, thick EVA foam, which can vary between 5 mm and 12 mm, is ideal for structures that need more rigidity and volume, such as armor, swords or large accessories in cosplay.

How to cut it without breaking or deforming?

Cutting high thicknesses accurately requires the use of sharp tools. A precision modeling cutter is recommended to obtain clean edges. To avoid warping the material, be sure not to apply too much pressure in a single pass; instead, make smooth, controlled cuts. It is also helpful to use a metal ruler to guide the cut and obtain straight lines. Keeping the blades sharp is essential to avoid jagged or ragged edges.

Is the thick EVA foam water and heat-resistan?

Yes, it is water resistant, which makes it suitable for use outdoors or in humid environments without risk of deterioration. However, when it comes to heat, it is important to note that the material can deform if exposed to temperatures above 80°C. Although it is flexible and can be molded with a heat gun, it is not recommended to expose it to extreme heat for long periods, as it could lose its original shape.

How to glue thick EVA effectively?

To bond thick pieces effectively, contact glue is the best option. Apply a thin layer on both surfaces you want to bond, let it air dry for a few minutes until the glue is tacky to the touch, and then press firmly. This technique ensures a strong and durable bond. You can also use glue sticks for small joints, but be careful with high temperatures to avoid deformation of the material.

How many millimeters thick it is?

The thickness varies between 5 mm and 12 mm, although you can also find thicker or thinner sheets depending on the supplier and the intended use. The thicker sheets, 10 mm or more, are ideal for creating large-volume structures, such as armor or large set pieces in cosplay.

What tools are needed to work with it?

Essential tools for working with this material include a sharp modeling cutter, sturdy scissors, a metal ruler, and a heat gun for shaping the material. It is also helpful to have contact glue or a hot glue gun on hand to join the pieces together. For finer details, you can use a dremel or sandpaper to smooth edges and create textures. The versatility of the material allows you to use a variety of tools, depending on the complexity of the project.

Is it possible to paint thick EVA foam and what paints to use?

Yes, it can be painted, but it is advisable to seal the surface first to obtain a smoother finish. Sealing can be done with heat, decoupage medium, liquid latex or even white glue diluted in water. After sealing, acrylic paints are an excellent choice for bright, long-lasting colors. You can also use spray paint to cover larger areas evenly. Apply several thin coats of paint to avoid cracks or imperfections.

How to use it in crafts or cosplay projects?

To create cosplay projects with these materials, you must first design a pattern on paper, then transfer it to the material and cut it accurately. Use a heat gun to mold the parts to the desired shape. Once the parts are molded, attach them with contact glue and make the final details with paint or texturing. Using layers of different thicknesses also helps to create three-dimensional effects and details on armor and accessories.

Is it safe for children and crafts?

Yes, it is safe for children as it is non-toxic and does not release harmful fumes. However, when working with cutting tools or heat, it is important that adults supervise to avoid accidents. This material is ideal for school crafts or creative projects, as long as the right tools are used.

How can thick EVA foam be molded or heated to shape it?

Shaping thick EVA foam is achieved by applying heat with a heat gun or an industrial dryer. When the material is heated, it becomes flexible and can be easily bent and shaped. Once it cools, it retains the shape you have given it. This process is essential in the creation of cosplay pieces, such as armor or helmets, where specific curved shapes or contours are needed.

Tips for proper maintenance

Although it is a resistant material, it can benefit from some care:

  • Protection from the sun: prolonged exposure to the sun can cause it to lose flexibility. Therefore, to preserve it, it is recommended to store it in cool and dry places.
  • Gentle cleaning: In case of dirt, a damp cloth and a little mild soap are sufficient to clean the surface. Avoid abrasive products that may damage the texture.
  • Varnishing for durability: Applying a varnish or sealant after painting a piece of this material can protect it from scratches and wear.

What is the difference between thick EVA foam and foamy?

Although often used interchangeably, thick EVA foam and foamy are technically the same material (ethylene-vinyl acetate), but the term “foamy” usually refers to thinner, more flexible versions. The former is generally denser and more robust, suitable for projects that need additional stiffness and durability.

For those looking to purchase quality foam, you should look to specialty modeling and craft stores, such as Green Stuff World, which offer a wide selection of colors and thicknesses. Our online stores allow you to get great prices and a wide variety of options, plus the convenience of having the product delivered right to your home.
