DIY Guide: How to Waterproof Felt
If you’ve ever worked with felt, you know how versatile and appealing this material can be. Whether you’re creating crafts, accessories, or home decor items, felt offers endless possibilities.
However, one common concern when working with felt is its vulnerability to moisture.
Let’s explore how you can make felt water-resistant so that your projects stay durable and long-lasting.
By the way, if you’re looking for more information on how to waterproof a felt hat, simply scroll down to the end of this guide.
Is Felt Waterproof?
Felt is not waterproof. It is made from compressed and matted fibers, typically from wool or synthetic materials, which allow water to penetrate easily. However, felt can be made water-resistant or even waterproof with the help of a waterproofing spray or fabric waterproofing wax.
Waterproofing sprays and wax work by forming a layer on the surface of the felt that repels water, preventing it from being absorbed into the fibers.
Keep in mind that not all types of felt may be suitable for waterproofing. The effectiveness of waterproofing treatments can vary depending on the quality and composition of the felt.
Additionally, the waterproofing process may alter the look, feel, or breathability of the felt. Read the product labels, and conduct patch tests before applying waterproofing treatments to the entire piece of felt.
Step-by-Step Guide on How to Waterproof Felt
Step 1: Gather the Necessary Materials
To waterproof felt, you’ll need the following items:
- Waterproofing spray or fabric waterproofing wax
- Soft brush or cloth for application
Step 2: Prepare Your Work Area
If you’re using a waterproofing spray, apply it in a well-ventilated area or outdoor space. Make sure the area is protected from overspray. Lay down a drop cloth or newspaper to catch any excess.
The same is valid if you’re using fabric waterproofing wax.
Step 3: Clean the Felt
Make sure the felt is clean and free from any dirt or debris. Gently brush off any loose particles using a soft brush or cloth.
If the felt is heavily soiled, you can lightly wash it by hand with mild soap and water and let it air dry completely before applying the waterproofing spray or wax.
Step 4: Test on a Small Area
If you’re unsure about how the waterproofing product will affect the color or texture of the felt, test it on a small area first.
This way, you can assess the result before applying it to the entire item.
Step 5: Apply the Waterproofing Spray or Wax
Hold the waterproofing spray canister about 6 to 8 inches away from the felt surface. Apply an even coat of the product.
If you’re using a fabric waterproofing wax, rub a small amount onto a clean, soft cloth and then apply it to the felt using gentle, circular motions.
Make sure to cover the entire surface of the felt.
⇒ Quick Tip:
Gently press down on the felt and smooth out any wrinkles or creases. It’s essential to have a wrinkle-free surface to ensure that the waterproofing spray or wax is evenly applied.
Step 6: Let It Dry
After applying the waterproofing spray or wax, allow the felt to dry completely in a well-ventilated area.
Follow the manufacturer’s instructions for the recommended drying time. It’s essential to ensure that the felt is fully dry before using or exposing it to any moisture.
For a higher level of waterproofing, you can repeat the process by applying an additional coat of waterproofing spray or wax. Just make sure to allow the felt to dry completely between each coat.
To test the results, pour a small amount of water on the surface of the felt. If the water beads up and rolls off the surface of the felt, it indicates that the felt is waterproof.
⇒ Quick Tip:
If your felt item has lost its shape or structure during the waterproofing process, you can reshape it while it’s still damp. Use clothespins or clips to secure the felt in the desired shape, and let it dry flat on a clean surface.
The effectiveness of the waterproofing depends on the quality of the product and the level of exposure to moisture.
How to Waterproof a Felt Hat
To waterproof your felt hat, you need to apply a waterproofing spray specifically formulated for felt or fabrics. Look for products that are designed to maintain the appearance and quality of the felt while providing effective waterproofing.
Before applying the waterproofing product to the entire hat, perform a patch test on a small area of the hat. This will help you ensure that the product does not cause any adverse effects on the felt, such as discoloration or texture changes.
After applying the spray, use a soft brush or cloth to gently work the waterproofing product into the fibers of the felt. This helps ensure even coverage and penetration of the spray into the material.
What waterproofing spray should I use for felt?
The Nikwax Fabric & Leather Proof spray is highly recommended by many individuals. To begin, ensure that your hat is clean. Next, apply a layer of the spray and gently wipe it across the surface. Allow it to dry, and then apply a second coat if necessary.
Please be aware that the coating may cause a slight darkening effect. Take note of this potential change in appearance.
Waterproofing may be necessary for wool or rabbit-felt hats, but not for beaver fur felt hats. Beaver fur felt is naturally dense, strong, and tightly compacted due to the microscopic barbs on the beaver fur, making it inherently resistant to water.
That’s it! With these simple steps, you can confidently waterproof your felt projects or your favorite felt hat.
