Product overview

Flexible Filler is a water-based acrylic filler for seams and gaps in foam armour, cosplay thermoplastics, fabrics, plastics and 3D-printed parts. It remains flexible after drying, allowing a filled joint to move with a worn or bent prop instead of cracking away from the surrounding material. Apply it in thin layers with a spatula, silicone applicator or finger, then smooth the surface with a wet finger to reduce later sanding. Drying takes 15 minutes to an hour depending on thickness and temperature, after which the repair can be sanded and painted.

Supplied in a 250 g screw-lid tub.
It adheres to foam, fabrics and plastics, including ThermoArt, Worbla, Thibra and WonderFlex.
Apply it in thin layers and smooth the wet surface with a damp finger to reduce sanding.
Sand the dry repair with abrasives between 320 and 600 grit.
The filler and applied paint remain able to move with a flexing part.
Its lightweight formulation is intended to avoid adding unnecessary weight to foam armour and props.

Notes · Q & A

What is a one-part modelling filler?

A one-part modelling filler is supplied ready to apply from the tube and needs no hardener, mixing ratio or kneading. Use it to fill seams, small gaps and surface imperfections, then allow it to dry before sanding. This differs from a two-part epoxy putty, whose separate components must be mixed before use.

How should I apply and level a one-part filler?

Apply a small amount with a spatula or similar tool to a clean, dry and grease-free surface. Press the filler into the defect and remove as much excess as possible before it dries, using water for clean-up where the product instructions allow. Leaving the repair close to level reduces the amount of sanding needed later.

How can I sand the repair without removing surrounding detail?

Let the filler dry fully, then begin with a fine abrasive and work only over the repair. Use a small sanding sponge or narrow abrasive strip around raised detail, checking the surface often. Stop when the filler is level with the surrounding part; broad, heavy sanding can flatten nearby rivets, panel lines or texture.

How should I fill a deep gap?

Build deep gaps in several thin applications rather than one heavy mass. Let each layer dry before adding the next, and keep the filler within the joint as much as possible. Thin layers are easier to control, reduce the amount of sanding and make it less likely that surrounding detail will be buried.
