AK Modelling Putty White is a ready-to-use, one-component filler for correcting seams and surface imperfections before sanding. This is the high-hardness grade in the tube-putty family, clearly distinct from the standard-hardness grey version. Its superfine consistency is intended for modelling work where the repaired area will be levelled and sanded back. The water-based polyurethane formulation dries without shrinkage, and no separate hardener or mixing step is involved.
AK identifies this as the high-hardness white grade.
The tube contains 20 ml, with a stated net weight of 39 g.
AK describes the filler as superfine, with adhesion and sanding properties.
The water-based formulation can be cleaned off with water, and AK states that being water based means no smelly chemicals in the mix.
AK publishes no drying time or sanding-ready time for this product.

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.
