Why It’s Important to Make Air-Dry Clay Waterproof?

Air-dry clay, commonly known as polymer clay, is a type of modeling material that hardens without the need for baking. It is a versatile material used for various projects, from jewelry to sculpture.

However, the downside to air-dry clay is that it is not waterproof. Over time, exposure to water can cause the clay to break down and crumble. This is why making air-dry clay waterproof is important, both for aesthetic and durability purposes.

Waterproofing the air dry clay can help protect the item from damage or discoloration due to water exposure. Additionally, it can make the clay more durable and better able to withstand wear and tear.

If you use air dry clay for crafting, you can use several easy methods to make the finished product more water-resistant.

8 Best Ways on How to Make Air-Dry Clay Waterproof:

1. Using Liquid Epoxy Resin:

The easiest and most reliable way to make your air-dry clay waterproof is by using liquid epoxy resin. It can be applied with a brush or roller, forming a solid waterproof coating over the surface of your project.

You can use this sealant on both the interior and exterior surfaces of your air-dry clay project.

2. Seal with Acrylic Sealer:

Another great option for making air-dry clay water-resistant is to seal it with acrylic sealer. This will provide a waterproof barrier that will protect your project from the elements and keep it looking beautiful for years.

Simply apply the sealant to the entire surface of your air dry clay and allow it to dry before adding any additional layers or decorations.

3. Use Mod Podge:

Mod Podge is a great way to give your air dry clay projects an extra layer of protection. Simply brush on the Mod Podge and allow it to dry completely before adding additional layers or decorations.

This will create a thin, waterproof coating that will help protect your project from water damage and wear and tear. Remember that this may change the color of your air dry clay, so be sure to test it on a scrap piece before applying it to your project.

4. Using Varnish:

Another way to protect your air dry clay is by using a varnish. This will create an even thicker protection coating than Mod Podge and can be used on any type of finish (glossy, matte, etc.).

Simply brush on the Varnish and let it dry completely before adding additional layers or decorations. Remember that using a glossy varnish may darken the color of your clay and should be tested on a scrap piece first.

5. Using White Craft Glue:

White craft glue is a great and easy way to protect your clay. Simply brush a thin layer onto the project and allow it to dry completely before decorating or painting the piece.

If desired, the craft glue will give a matte finish that can be further sealed with a varnish or Mod Podge. Be sure to test the glue on a scrap piece before applying it to your project.

6. Using Shellac:

Shellac is a type of sealer that gives the clay an almost glassy finish and will add a layer of protection against chipping and cracking. It is especially good for pieces used in the kitchen or items that need to be wiped down regularly, as it adds a waterproof layer.

It can be applied with a brush or sprayed on for a smoother finish. To apply it, the clay should first be cleaned and dried. Then apply the Shellac to the surface and allow it to dry for at least 8 hours.

Finally, buff with a soft cloth or brush for a glossy shine.

Note: Shellac can be applied multiple times if needed but should be allowed to dry completely between every application.

7. Sealing with Polycrylic:

Polycrylic is a water-based sealer that helps to protect clay pieces from scratches and water damage. It is a clear sealant that will not turn yellow over time.

Before applying it, the clay needs to be completely dry and clean. Then, use a brush or sponge to apply a thin layer of Polycrylic over the surface.

Allow it to dry completely before touching the piece. You may need to apply several layers for a durable seal. Polycrylic can also be used over paint, ink, and other mediums to protect them from damage.

8. Apply Glaze:

Glaze is a liquid clay that gives a glossy finish to any clay piece. It also helps protect the piece from dirt and other contaminants. To apply it, use a soft brush to brush a thin layer of glaze over the piece in one direction.

Apply Glaze

Allow the piece to dry completely before applying additional layers. Be sure to clean the brush after each use. Wait until the glaze has dried completely before handling or displaying the piece.

What happens to air-dry clay in water?

Air-dry clay will become soft and pliable when exposed to water, but it will not dissolve. Once the clay has dried completely, it will become hard and brittle again.

Depending on the type of clay, it may also change in color when wet. It is important to note that air dry clay should not be submerged in water for long periods, which will cause the clay to break down. Use a sealant or varnish afterward to preserve your air-dry clay project.

Does acrylic paint seal air-dry clay? 

Yes, acrylic paint can be used to seal air-dry clay. The paint creates a film that protects the clay from moisture and ensures it will last longer.

If you plan to use the clay outdoors, applying several layers of paint or a sealant is important to protect the clay from the elements.
