5-minute or 30-minute epoxy?

5-minute for small repairs and quick bonds. 30-60 minute for larger assemblies where you need more working time and maximum strength. Slow-cure epoxies are generally stronger.

Can epoxy bond metal to wood?

Yes, epoxy excels at bonding dissimilar materials. Roughen both surfaces for best adhesion.

Epoxy Adhesive: Two-Part Structural Bonding for Multiple Materials (2026)

Prepared by Lumberama's Building Materials Team

|Last updated May 25, 2026|Sources & methodology

Epoxy adhesive is a two-part system (resin and hardener) that creates extremely strong, waterproof, and chemical-resistant bonds on virtually any material. Unlike other adhesives, epoxy fills gaps and bonds dissimilar materials together. Available in quick-set (5 minute) to slow-cure (60+ minute) formulas for different applications.

Key Features

Two-part resin and hardener system; Bonds virtually any material; Gap-filling capability; Waterproof and chemical resistant; Fast-set and slow-cure options

Specifications

Types: 5-minute

30-minute

60-minute | Strength: 3000-5000+ PSI | Cure: 5-60 minutes working time

24 hours full | Mix ratio: 1:1 most consumer products | Temperature resistance: up to 200°F | Chemical resistance: high

Applications

Metal to wood bonding; Concrete repair and anchoring; Filling voids and gaps in wood; Bonding dissimilar materials; Marine and underwater repairs

Installation Overview

Mix equal parts resin and hardener on disposable surface. Stir thoroughly for 1-2 minutes. Apply to both surfaces within working time. Press together and support until cured. Clean excess before cure with acetone. Full strength in 24 hours.

Pros & Cons

Pros

✓ Extremely strong structural bonds; Bonds almost any material; Fills gaps unlike other adhesives; Waterproof and chemical resistant

Cons

✗ Must be mixed precisely; Short working time on fast-set; Difficult cleanup once cured; More expensive than other adhesives

Code Requirements

Structural epoxy anchoring in concrete must meet ACI 318 requirements. Must be appropriate for substrate materials. Chemical resistance must match application environment.

Buying Tips

Choose working time based on project complexity - longer working time for larger assemblies; Roughen smooth surfaces with sandpaper before epoxy application for the best bond; JB Weld Original is the go-to for metal repairs; West System is the standard for marine applications
