Product overview

This 1 lb (454 g) kit of Aves Fixit comes in Black: a two-part repair compound blended by hand from its A and B tubs in a one-to-one ratio. The result is a firm, smooth putty with industrial-strength grip and a working window of 1–3 hours: time to fill, shape and feather the edges with water. It hardens by itself, no oven needed, and reaches a rock-hard, semi-gloss cure in 24 hours with 0% shrinkage. It holds to metal, fibreglass, plastics, wood, tile, stone and other epoxies, a dependable fix for model vehicles, props and workshop parts.

Knead the two equal halves together for roughly 2 minutes, until no streaks remain
Takes heat up to 500 °F (260 °C) and stands up to fuel and UV
Drill, tap, sand or machine the cured putty
Sets up under water, and the cured fill is waterproof
Non-conductive and non-flammable; accepts any type of paint

Why Black

Choose black for dark work: black plastic, tyres and hoses meant to look like rubber, dark resin, cast iron or anything painted a deep colour. A chip filled in black vanishes without repainting the whole part, and building up in black beneath a dark basecoat means no pale putty shows on worn edges. The catch is that black swallows detail while you model, so work under a low side light.

The 1 lb pack

One kit holds Part A and Part B, 454 g in total: the middle of the three Fixit sizes we stock, enough for a terrain project or a run of repairs. The other sizes in this colour are linked in the specification table. Mix only what you can use within the working time; once A and B meet, it cures whether you have finished or not.

Worth knowing

It cures rigid, so it is not for parts that need to flex, and for fine figure sculpting Apoxie Sculpt is the smoother compound.

Not for safety-critical or load-bearing parts, or pressurised gas and fuel systems. We hold no food-contact certification for it, so keep it off surfaces that touch food or drink.

It may cause an allergic skin reaction and eye irritation: wear gloves when mixing. Sanding dust from the cured putty contains crystalline silica, so wear a dust mask and safety glasses. Keep it away from children.

Notes · Q & A

Apoxie Sculpt, Apoxie Clay or Fixit — which Aves compound do I need?

All three are two-part epoxy compounds mixed in equal amounts that harden on their own, with no oven or kiln. Apoxie Sculpt is the smooth, all-round sculpting compound in a wide choice of colours. Apoxie Clay has a fine, clay-like grain for detail and texture. Fixit is the firmer repair formula, heat rated to 260 °C and resistant to fuel, for fills, bonds and rebuilt parts.

How do I mix it, and how long can I work it?

Take equal amounts of Part A and Part B, ideally wearing nitrile gloves, and knead for about two minutes until the colour is completely even with no streaks; under-mixed putty leaves soft spots. Working time varies by product, from about one hour to three, and is listed on each product page. All of them reach full cure in 24 hours.

How do I smooth it, and what cleans it up?

While it is still workable, smooth or texture the surface with a little water on a finger, brush or tool, or with Aves Safety Solvent, which also lifts fingerprints; Apoxie Clay is smoothed with the solvent. Hands and tools clean up with soap and water before the compound sets. Once cured, only sanding or carving will remove it.

Can I sand, drill and paint it once cured, and what precautions should I take?

After the full cure it can be sanded, filed, drilled, tapped or turned without chipping, and it takes paint wet or cured. It does not shrink, and it is waterproof and freeze-thaw stable. Wear gloves when mixing, since the uncured compound can cause a skin allergy and eye irritation, and a dust mask and safety glasses when sanding.
