Devcon Repair Compound Range — Quick Reference by Application
Devcon is the trusted industrial repair brand — used worldwide by maintenance engineers to rebuild worn metal surfaces, repair pump housings, seal leaks and protect equipment from abrasion without welding or replacement. The range maps to repair type — match the compound to the substrate (steel, aluminium, concrete, rubber), the load type (structural, abrasion, chemical) and the working time required.
| Repair Type | Devcon Product | Best For |
|---|---|---|
| Structural Steel Repair (slow-set) | Plastic Steel Putty (A), Plastic Steel Liquid (B) | Worn shaft sleeves, housings, pump casings — full strength after 16 hour cure |
| Fast Emergency Repair | 5-Minute Epoxy, Plastic Steel 5-Minute | Production stoppages, on-site quick fixes, leak repair under pressure |
| Aluminium Repair | Aluminium Putty (F), Aluminium Liquid (F-2) | Aluminium castings, machinery housings, marine alloy repairs |
| Wear Resistance / Abrasion | Wear Resistant Putty, Brushable Ceramic, Pneu-Wear | Slurry pump linings, chute liners, hoppers, conveyor wear plates |
| Flexible / Rubber Repair | Flexane 80/94 Putty, Flexane Liquid | Belt repair, rubber lining, vibration mount rebuild, gaskets |
| Titanium Repair | Titanium Putty | Lightweight high-strength repair — non-magnetic, machinable |
| Concrete & Masonry | Concrete Patch, Concrete Repair | Floor crack repair, anchor bolt setting, vertical patching |
Devcon compounds are machinable after full cure — drill, tap, mill or turn to restore precision tolerances.

People Also Ask — Devcon Repair Compounds
Q: What is Devcon and when do I use it?
Devcon (now part of ITW Performance Polymers) makes high-performance epoxy and metallic repair compounds — Plastic Steel A/B Liquid and Putty, Wear Resistant Putty, Brushable Ceramic, Aluminium Putty, and Stainless Steel Putty. Used for emergency repairs of cracked castings, pump housings, gearbox cases, worn shafts, and any application where replacement isn't immediately possible. Devcon has been the engineering repair standard since the 1950s — well-known to maintenance teams across mining, manufacturing, and transport.
Q: Plastic Steel A or B — what's the difference?
Plastic Steel A is liquid (pourable for filling holes, low-viscosity for impregnating cracks). Plastic Steel B is putty (mouldable, holds shape on vertical surfaces, fills gaps without slumping). Both cure to a steel-grey hardness similar to mild steel — machinable, drillable, tappable after full cure. Use A for fluid filling and pinhole repairs; use B for structural repair of broken castings or shaped parts. Both are workshop standards held in any well-equipped maintenance shop.
Q: How long does Devcon take to cure?
Plastic Steel A/B: handling strength in 4-6 hours, full cure 16-24 hours at 25°C. Faster cure at higher temperatures (oven cure at 65°C reduces to 1-2 hours). Slower cure below 15°C — heat the work area or move to a warmer location. Don't load the repair until full cure — premature load reduces final strength dramatically. For critical repairs, allow 48-72 hours and verify cure with thumbnail-scratch test.
Q: Can I machine cured Devcon?
Yes — cured Plastic Steel can be drilled, tapped, milled, ground, and surface-finished. Use sharp HSS or carbide tools, light feeds, and adequate cooling. The cured material is roughly equivalent to mild steel in machining behaviour but slightly more abrasive — tool life is reduced compared to mild steel. For thread holes, drill+tap as for steel; the repair holds threads reliably. For final-surface tolerance, leave 0.5-1mm of Devcon proud and machine to size after full cure.
Q: Will Devcon hold a stripped bolt thread?
For light-load repairs, yes — drill out the damaged thread to clean metal, fill with Devcon Plastic Steel B, allow to cure, then drill and tap the new thread. Works well for non-critical fasteners. For load-bearing or vibration-exposed bolting, use a [Recoil thread insert](/collections/recoil) instead — proper insert restoration is stronger and more reliable. Devcon thread-recovery is best for light-duty bracket and cover fasteners where insert installation isn't practical.
