Putty kit Army Painter Green Stuff — modelling two-part epoxy putty (blue and yellow components)

Army Painter Green Stuff is a two-part epoxy modelling putty supplied as blue and yellow components that must be mixed to form a green, workable filler. Designed for miniature modelling and figure repair, it provides a sculptable, gap-filling compound for seams, conversions and small repairs on plastic, resin and metal miniatures. The putty cures at room temperature and delivers a firm surface suitable for further sanding, filing and painting after full cure.

Advantages

When mixed in equal parts, the blue and yellow components produce an even green putty with a predictable working time. The material offers good sculptability for adding details, blending seams and performing conversions, while its fast initial setting enables relatively quick progression through modelling steps. Compatible with common miniature materials, it bonds well when used alongside adhesives for larger joins and provides a stable base for primer and paint once fully cured.

Suitable for

• Filling mold lines and gaps on miniatures
• Sculpting small details and making conversions
• Repairing chips and broken parts on plastic, resin or metal figures
• Blending seams and preparing surfaces for painting

Key specifications

• Two-part epoxy putty supplied as separate blue and yellow components
• Mix ratio: equal parts of each component to achieve workable putty
• Work time after mixing: approximately 20–30 minutes for molding and shaping
• Full cure: reaches handling hardness within hours at room temperature; suitable for sanding and painting after full cure
• Compatible surfaces: plastic, resin and metal miniature materials

How to use

Cut or remove equal amounts of the blue and yellow putty and knead them together until a uniform green color is achieved. Apply the mixed putty to the area requiring filling, sculpting or repair, shaping with modelling tools or fingers while within the working time. Smooth seams and blend edges before the material begins to set. For larger structural joins, use the putty in conjunction with an appropriate adhesive to secure components, then apply putty for gap-filling and finishing.

Usage recommendations

Work in small batches that match the 20–30 minute work time; keep unused sealed components stored per manufacturer guidance. After full cure, prepare the surface with light sanding or filing before priming and painting. Avoid exposing uncured putty to high humidity or extreme temperatures to ensure consistent curing.
