Aves FIXIT Two-Part Repair Compound Putty — 2-Part A & B, Waterproof & Machinable

Aves FIXIT is a two-part, industrial-strength modelling and repair compound that mixes into a putty for filling, rebuilding, and permanently bonding most materials.

Whether you’re restoring a cracked ceramic planter, repairing a corroded metal bracket, rebuilding boat trim, or sculpting details during model work, Aves FIXIT delivers a rock-hard finish after curing. Its smooth, malleable texture makes shaping and blending straightforward, and the waterproof, freeze-thaw stable cured resin stands up to outdoor, marine, and heavy-use environments. FIXIT is formulated for both professional and hobby applications, giving a long working window and predictable set and post-cure machinability.

How do I prepare and mix Aves FIXIT for best results?

Preparation is simple: clean and degrease surfaces, remove loose material, and wear nitrile gloves. Measure equal parts of Part A and Part B and knead until the colour is uniform; that indicates a proper mix and reliable curing. Maintain ambient temperatures recommended on the product label for consistent setting time.

• Clean substrate of oil, dust, and oxidation for better adhesion.
• Mix equal volumes of A and B; knead about 2 minutes until consistent colour.
• Work time is about 1–3 hours depending on temperature; full cure in 24 hours.

What materials will FIXIT bond to and hold up on?

FIXIT bonds to a wide range of common materials, including metal, wood, ceramic, tile, masonry, fibreglass, and many plastics. Once fully cured it forms a dense, semi-gloss surface that resists chipping and abrasion, making it suitable for high-wear or outdoor uses. For plastics or oily metals, surface preparation improves adhesion and longevity.

• Adheres to metal, wood, ceramic, tile, masonry, and fibreglass.
• Waterproof and freeze-thaw stable for exterior or marine repairs.
• Can be sanded, drilled, tapped, carved, or lathed after full cure.

How does FIXIT perform during and after curing?

During working time the compound behaves like a putty—soft, malleable and easy to shape or tool. It self-hardens without baking into a rock-hard finish with no significant shrinkage or cracking. After 24 hours the cured material accepts sanding, drilling, and painting so you can finish repairs cleanly and integrate them aesthetically into the original surface.

• 1–2 hours of typical working time; toolable up to 3 hours in many conditions.
• Sets hard in about 24 hours; no baking required; minimal shrinkage.
• Post-cure machinable for precise restoration and finishing work.

How do I apply and finish repairs made with FIXIT?

After mixing, press FIXIT firmly into gaps or onto damaged areas, sculpt or stamp to shape, and smooth the surface with appropriate tools or wet-finger technique. Remove excess while still workable and allow full cure before aggressive finishing. Cleanup of tools and hands (while still uncured) is simple with water or Aves Finishing Solution.

• Pack and compress into voids to ensure full contact and bonding.
• Smooth with tools, solvents, or water; trim after partial cure if needed.
• Sand, paint, or machine once fully cured for a clean finish.

Who is this for? Aves FIXIT is aimed at craftsmen, modelers, restorers, DIYers, marine technicians, and light-industrial users who need a reliable, multi-surface repair compound that’s easy to shape but finishes hard and durable. If you want a single two-part putty for patching, rebuilding, sealing, and sculpting across metal, wood, ceramic, and composite projects—especially where waterproof or outdoor performance matters—FIXIT provides a predictable, machinable result.
