Can You Seal Air Dry Clay to Make It Waterproof?
Yes, you can seal air-dry clay to make it waterproof. The most common way to do this is by using a sealant such as Mod Podge or an acrylic spray sealer. These sealants will help protect the clay from moisture and keep it from cracking or warping over time.
When applying a sealant, it’s important to use a light, even coat and allow it to fully dry in between coats. This will help ensure that the sealant is evenly distributed and your clay is properly protected. It’s also important to note that while some sealants may be labeled as waterproof, this doesn’t mean they can completely protect air-dry clay from water damage forever.
After some time, the sealant will start to wear off and need to be reapplied. Therefore, it’s best to keep your air-dry clay projects away from any extended exposure to moisture or water, if possible.
It’s also possible to use other substances like varnish or liquid polymer clay for sealing air-dry clay. However, these options should only be used by experienced crafters, as they require special techniques and safety precautions. In the end, it’s best to stick with sealants that are specially designed for air-dry clay projects if you’re looking for a reliable way to make your creations waterproof.
Every project is unique, so make sure to do some research and determine which type of sealant is best suited for the type of air-dry clay you’re using. That way, you’ll be able to create beautiful projects that last! With the right kind of sealant, you can keep your air-dry clay projects protected from moisture and water damage for years to come.
10 Methods How to Seal Air Dry Clay
1. Pre-Bake Your Clay
If you plan on painting your air dry clay project, pre-baking the clay will help to ensure that your paint adheres to the surface of the clay. To pre-bake your clay, simply place it on a baking sheet and bake it in a preheated oven at 200 degrees Fahrenheit for 30 minutes. Make sure to keep an eye on your project while it is baking, as the clay can burn easily.
2. Seal with Mod Podge
Mod podge is a water-based sealer that can be used on a variety of surfaces, including air-dry clay. To seal your clay with mod podge, simply brush a thin layer over the surface of the clay and allow it to dry. Repeat this process until the desired level of protection is achieved.
This method will not only protect your air-dry clay from cracking and breaking, but it will also add a glossy finish to the surface of your project. If you are using paint or ink on your clay, be sure to seal it before applying the Mod Podge, as this will help to ensure that the colors stay bright and true.
3. Seal with Acrylic Varnish
Acrylic varnish is another type of sealer that can be used on air dry clay. Like mod podge, the acrylic varnish will help to protect your clay from damage and keep paint from chipping or flaking off. To use acrylic varnish, simply brush a thin layer over the surface of the clay and allow it to dry. You can also use a spray-on varnish for even coverage.
Once the varnish is completely dry, you can then paint and decorate the piece as desired. For extra protection, you can apply multiple layers of acrylic varnish until the desired look is achieved. Keep in mind that if you use acrylic paint on the clay, you should also use acrylic varnish to seal the piece.
4. Use a Spray Sealer
Spray sealers are another option for sealing air dry clay. They provide a quick and easy way to seal your clay without having to brush on a sealer. Simply hold the can about 6 inches away from the surface of the clay and spray evenly over the entire surface.
Allow the sealer to dry before painting or to handle the clay. Spray sealers can be found at craft and art supply stores. Be sure to follow all of the manufacturer’s instructions when using a spray sealer.
5. Paint Before You Bake
If you plan on painting your air dry clay project, you can actually paint the clay before you bake it. This will help to prevent the paint from chipping or flaking off when you bake the clay. Simply paint your design onto the surface of the raw clay and then bake according to the directions.
The paint will not burn off and will result in vibrant colors once the clay is finished baking. If you don’t plan to paint your project, you can skip this step.
6. Sand before You Paint
If you want a smooth finish for your air dry clay project, sanding before you paint is a good idea. Sanding will help to smooth out any bumps or imperfections on the surface of the clay. To sand your air-dry clay, use fine-grit sandpaper and lightly sand over the entire surface. Wipe away any dust with a damp cloth before painting.
This will help to give your project a professional look. Once you have finished sanding, your air-dry clay is ready to be painted. You can use any type of paint that you like. Acrylic and spray paint are both great options for air-dry clay projects.
7. Use an Underglaze
Underglazes are ceramic paints that can be used on raw or bisque-fired ceramics. They are available in a wide variety of colors and can be applied directly to the surface of air-dry clay. Once applied, they need to be covered with a clear glaze before being fired in a kiln. However, they can also be left unglazed if desired.
8 . Use Watercolors
Watercolors can also be used on air dry clay projects. They provide a beautiful translucent color that can add depth and dimension to your project. Watercolors can be applied directly to the surface of raw or bisque-fired air-dry clay. Once applied, they need to be covered with a clear glaze before being fired in a kiln; however, they can also be left unglazed if desired.
9. Use an Oil Pastel
Oil pastels are a great way to add color and texture to air-dry clay projects. They provide a rich, vibrant color that can be used to create beautiful designs on the surface of your project. Oil pastels should not be fired in a kiln; instead, they should be sealed with a varnish or sealer before being left to air-dry.
10. Seal with a Clear Glaze
Lastly, if you plan on firing your air dry clay project in a kiln, it’s best to use a clear glaze as the final sealant. Clear glazes help to protect the surface of the clay while providing a glossy finish that will last for years.
When applying the glaze, use a soft brush and apply a thin layer of glaze over the entire surface of your project. Let it dry completely before baking in a kiln according to the manufacturer’s instructions. Once complete, your project will be ready to enjoy!
4 Things to Consider When Sealing Air Dry Clay:
1. Pick the Right Sealant:
The type of sealant you choose will depend on the type of air-dry clay you’re using and the project you’re working on. For most projects, a clear acrylic sealer or a matte varnish is best.
2. Test First:
Before sealing your entire project, always test the sealant on a small piece of air-dry clay first. This will allow you to ensure that the sealant is compatible with your clay and that it provides the effect you’re looking for.
3. Prepare Your Clay:
Before applying any sealant, make sure your project is completely dry and free from dust or other particles. You can use a soft brush to gently remove any dust.
4. Apply the Sealant:
Apply the sealant in thin layers with a foam brush or spray can, making sure to cover all areas of your project. Allow the sealant to dry completely before applying a second coat. It’s best to apply two or more coats of sealant for a better, longer-lasting finish.
Conclusion:
Sealing air dry clay is important to prevent it from drying out and cracking. There are a few different ways that you can seal your air dry clay, depending on what you have available. You can use clear nail polish, Mod Podge, or even just a spray sealer. Make sure to test a small area of your project before applying the sealant all over, in case there is any adverse reaction.
Once you’ve sealed your project, it will be protected from the elements and should last for many years to come! Thanks for reading our blog post on how to seal air dry clay! We hope you found it helpful and informative. Happy Sealing!
