Putty for scale models VALLEJO 70.400 — grey modelling filler, 1 pc

VALLEJO 70.400 grey modelling filler is a solvent-free putty formulated for filling seams, gaps and surface imperfections during assembly and repair of scale models. Supplied as a single unit, the paste cures to a hard, stone-like finish that accepts sanding and subsequent painting. It is compatible with common modelling substrates such as plastic and resin and integrates with VALLEJO painting and finishing materials when preparing surfaces for primer and topcoat.

Advantages

This modelling putty provides a dense, opaque finish that resists shrinkage and offers good adhesion to plastic and resin surfaces. It sands smoothly to create an even substrate for primer and paint, and its cured hardness supports detailed surface work and minor sculpting. Because it dries to a stone-hard texture, the filler is suitable for rebuilding small features or creating texture and high-relief details without collapsing or deforming during processing.

Suitable for

• Filling seams and gaps in plastic model kits
• Repairing and reshaping resin and cast parts
• Creating textures and high-relief details on miniatures
• Preparing surfaces before sanding, priming and painting

Key specifications

• Colour: grey
• Finish when cured: hard, opaque stone-like surface
• Suitable substrates: plastic, resin and similar modelling materials
• Application form: modelling paste/putty
• Typical processing: can be sanded and shaped after curing

How to use

Apply the putty sparingly to the area requiring repair using a spatula, modelling tool or similar applicator. Work the paste into seams or gaps and remove excess material before curing. Allow the filler to dry fully until it reaches a hard, stone-like state, then sand to the desired profile using appropriate grit sandpaper. After cleaning dust from the surface, proceed with primer and paint compatible with the model substrate.

Usage recommendations

Keep tools and hands clean while working to avoid contamination. For best results, test adhesion and drying on a scrap piece of the same material. Use progressively finer sanding grits to achieve a smooth surface before priming. Store the product in a cool, dry place with the container tightly closed to maintain workability and prevent premature hardening.
