Flexible Putty 250 ml

Flexible Sealing Putty is a specialized acrylic-based material designed to fill seams, gaps, and imperfections in cosplay materials such as EVA foam and thermoplastics, maintaining both their flexibility and ease of sanding. Unlike traditional putties that can become brittle, GSW Flexible Sealing Putty is formulated to bend and move with the surface, making it ideal for foam-based armor, weapons, and accessories.

In cosplay, achieving a smooth, professional finish is crucial, and this gap filler plays a key role. When constructing armor pieces from EVA foam, gaps and seams inevitably form where separate pieces are joined. These seams can be very visible, making a costume appear unfinished. A flexible sealing putty smooths out these imperfections, creating a Seamless appearance without sacrificing durability.

One of the biggest advantages of this material is its acrylic base, which allows it to be easily sanded and painted. Once dry, it can be smoothed with fine-grit sandpaper to create a uniform surface, making it an essential product for both professional and amateur cosplayers.

Another key aspect is its compatibility with thermoplastics such as ThermoArt, Worbla, Thibra, and WonderFlex. Unlike rigid joint sealants that can crack when applied to thermoformed materials, this one remains slightly elastic, ensuring its longevity. For large-scale props or costumes that require intricate details, this will help integrate sculpted elements seamlessly.

This is essential for cosplay making because it improves durability, finish quality, and paint adhesion on materials such as EVA foam and thermoplastics for cosplay.

How do you apply flexible sealant paste to EVA foam and thermoplastic materials?

Applying the flexible sealant paste correctly ensures the best possible results for your cosplay projects.

Follow these steps for optimal application:

1. Surface preparation:

• Make sure the EVA foam or thermoplastic is clean, dry, and free of dust or grease.
• If necessary, lightly sand the surface with a fine-grit sanding sponge to create a slightly rough texture, improving adhesion.

Application process:

• Use a small spatula, silicone applicator, or even your fingers to spread a thin layer over the seams or gaps.
• Avoid applying too much, as excess material will require additional sanding later.

Smoothing the surface:

• While still wet, dip a finger in water and smooth it gently to reduce the need for sanding later.
• For deeper gaps, apply in thin coats, allowing each coat to dry before adding more.

Drying time:

• Depending on the thickness of the application and the ambient temperature, drying can take between 15 minutes and one hour.
• To speed up the process, place the piece in a warm, well-ventilated location.

5. Sanding for a line-free finish Joining:

• Once completely dry, sand the surface with fine-grit sandpaper (320-600 grit)..
• Avoid pressing too hard to maintain flexibility.

6. Painting and Finishing Touches:

• Once the surface is smooth, apply primer and acrylic paint for a final finish.
• Its nature ensures the paint adheres without cracking, even when the piece is slightly bent.

By following these steps, you can guarantee a professional-quality finish on your armor, weapons, and cosplay accessories.

What are the advantages of using a flexible sealing paste instead of traditional ones?

Traditional ones, such as wood filler, modeling putty, or Epoxy-based products are rigid and prone to cracking when used on flexible surfaces like EVA foam. On the other hand, a flexible sealant putty offers multiple advantages specific to cosplay applications:

• Flexibility without cracking: EVA foam bends and flexes; traditional putties can crack over time, while ours adapts to movement.
• Better adhesion to foam and thermoplastics: This product adheres well to porous surfaces like cosplay foams and thermoformed thermoplastics.
• Easy sanding and paintable finish: The acrylic base allows for effortless sanding, resulting in a super-smooth finish that can be painted without primer.
• Lightweight formula: Heavy fillers can make foam armor heavier, but this flexible version is lightweight, making it ideal for large costumes and accessories.
• Multi-layer capability: Can be applied in thin layers to achieve different levels of smoothness and depth without losing structural integrity.

Can flexible filler be used on 3D printed cosplay accessories?

Yes! Flexible sealing pastes can be used on 3D printed accessories, especially those made from materials such as PLA, ABS, and TPU. Since many cosplayers mix 3D printing with EVA foam or other thermoplastics like ThermoArt, this product is a great way to smooth out layer lines, gaps, and imperfections on printed pieces.

How to use it on 3D prints:

1. Lightly sand the 3D print to create a better adhesion surface.
2. Apply with a spatula or a brush.
3. Let it dry completely before sanding.
4. Apply several thin coats if necessary to achieve a completely smooth finish.
5. Prime and paint as usual.

How durable is flexible filler?

Acrylic-based flexible filler is very durable, especially when used on materials such as EVA foam and thermoplastics. Once dry and sealed with paint or varnish, it becomes resistant to:

• Minor impacts and stresses: It will not crack with normal bending and movement.
• Moisture: Unlike wood fillers, it does not absorb water.
• Paint cracking: It provides a stable surface for the paint to adhere to. Adheres without peeling.
