Why Waterproof Air Dry Clay?

Before we dive into the process of making air dry clay waterproof, let’s first understand why it is essential. Air dry clay is a popular choice for many artists due to its ease of use and ability to harden without the need for baking or firing in a kiln. However, one major drawback of this material is its susceptibility to water damage.

Most air dry clay products are not waterproof, which means that exposure to water can cause them to soften, deform, or even dissolve completely. This limited lifespan of air dry clay projects makes it unsuitable for certain uses such as outdoor sculptures or functional objects like planters or bowls. That’s why knowing how to make air dry clay waterproof is crucial if you want to extend the life and versatility of your creations.

Materials Needed to Make Air Dry Clay Waterproof

Now that we understand the importance of waterproofing air dry clay let’s gather the materials needed for this process. The good news is that you probably already have most of these items at home!

Air Dry Clay:

This is your base material, and any brand or type will work.

Waterproof Sealant:

You can choose from various waterproof sealants such as Mod Podge, clear nail polish, or even regular waterproofing spray used for fabric or leather.

Paintbrush:

A small to medium-sized paintbrush will be needed to apply the sealant onto your clay creations.

Sandpaper (Optional):

If you want a smoother finish on your sealed clay, sandpaper can come in handy.

That’s all you’ll need! Let’s move on to the next step – making air dry clay waterproof.

11 Step-by-step Guidelines on How to Make Air Dry Clay Waterproof

Step 1: Prepare  Your Air Dry

Make sure it is completely dry before proceeding. It usually takes 24-48 hours for air dry clay to dry completely, but this may vary depending on the brand and thickness of your creation. You can test if your clay is dry by tapping it gently – if it sounds hollow, you’re good to go! But if it feels damp or cold, give it more time to dry. The key to achieving a waterproof seal is to start with a completely dry surface. The sealant will not adhere well to damp clay.

Step 2: Prepare Your Working Space

Cover your work surface with a plastic sheet or newspaper to protect it from any spills. It’s best to work in a well-ventilated area as some sealants may have a strong smell. You may also want to wear gloves to protect your hands from any chemicals. But don’t worry, most sealants are non-toxic and safe to use. The precautions are just for extra protection. If you’re using clear nail polish, make sure to work in a well-lit area as it can be challenging to see where you’ve applied the sealant.

Step 3: Choose Your Sealant

As mentioned earlier, you can choose from various waterproof sealants. Mod Podge is a popular choice amongst crafters as it is affordable and readily available. It also comes in different finishes, such as matte or glossy, depending on the look you want to achieve. Clear nail polish can work just as well and is perfect for small projects. But if you’re waterproofing a larger surface area, using a spray sealant may be more practical.

Step 4: Shake Your Sealant

If you’re using a spray or paint-on sealant, shake the container well before opening to ensure that it is thoroughly mixed. You may also want to stir your sealant if using a brush-on type, as it can sometimes separate and become lumpy. It’s essential to have a smooth and consistent application of sealant for the best results. But don’t worry if your sealant is already clumpy, as we’ll share a pro tip later on how to fix that!

Step 5: Apply the First Coat

Using your paintbrush or spray, apply a thin layer of sealant on to your dry air dry clay. Make sure to cover the entire surface evenly, including any small crevices or details. If you’re using a brush-on type of sealant, make sure to follow the direction of the strokes for a smooth finish. If using a spray sealant, be careful not to overspray. You don’t want any drips or puddles on your clay as it may affect the final look.

Step 6: Let It Dry

After applying the first coat of sealant, let it dry completely before moving on to the next step. This usually takes around 15-20 minutes for a brush-on sealant and 30 minutes to an hour for a spray sealant. Follow the label instructions on your specific sealant type for more accurate drying times. It’s essential to let each coat dry completely before proceeding to the next step.

Step 7: Check for Imperfections

After the first coat is dry, check if there are any imperfections or areas that may need additional coverage. If you see any spots that are still unsealed, apply another thin coat of sealant on those areas and let it dry. The number of coats needed may vary depending on your sealant type and the thickness of your clay. But usually, 2-3 coats should do the trick.

Step 8: Optional Sanding

If you want a smoother finish, you can lightly sand your sealed clay after the first coat has dried. Use a sandpaper and gently sand in circular motions until you achieve the desired smoothness. This step is entirely optional as some sealants already have a smooth finish, but sanding can help remove any visible brush strokes or bumps.

Step 9: Add Additional Coats (If Needed)

If you’re satisfied with the results after sanding, move on to the next step. But if you want a more durable seal, you can repeat steps 5-8 and add additional coats of sealant. The more layers you have, the better protected your creation will be from water damage. You can also choose to use a different finish for each coat, such as matte for the first layer and glossy for the last, to add more dimension to your clay.

Step 10: Fixing Clumpy Sealant

If your sealant has become clumpy or has dried out while working on your clay, don’t worry! You can quickly fix this by adding a few drops of water to the sealant and stirring it well. This should help revive the consistency of your sealant and make it easier to apply. If it’s still too thick, add a few more drops of water until you get the desired consistency.

Step 11: Let It Cure

After adding all the necessary coats and making sure your clay is waterproof, let it cure for 24 hours before using or displaying it. This will ensure that the sealant has completely dried and bonded to the clay surface. And voila! You now have a waterproof air dry clay creation that you can display or use without worrying about damage from water exposure.

Following these simple steps on how to make air dry clay waterproof, you can make any air dry clay creation waterproof and long-lasting. Whether it’s a cute figurine or a functional dish, adding a waterproof sealant will protect your creation from water damage and give it a beautiful finish. Now go ahead and create with confidence knowing that your clay creations are safe from the elements!
