We’ve all been there—a leaking hose, a cracked plastic part, a loose trim piece. Rather than head to the store or wait for a replacement, a quality epoxy or sealant can provide a fast and lasting repair.
Used correctly, these products can bond, seal, and reinforce almost anything around the garage or home. Here’s how to get the most out of them.
What’s the Difference Between Epoxies and Sealants?
Epoxies are strong, two-part adhesives that chemically cure to create a rigid, durable bond. They’re best for structural repairs where strength matters.
Sealants, on the other hand, stay flexible and are used to fill gaps or stop leaks. Think of them more like gap fillers and waterproof barriers.
- Use Epoxy for: Repairing broken plastics, cracked metal, bonding dissimilar materials
- Use Sealants for: Sealing seams, waterproofing joints, stopping drips or air leaks
Types of Epoxies and When to Use Them
- Quick-Set Epoxy: Ideal for fast repairs with minimal clamping
- Plastic Bonding Epoxy: Formulated for tricky materials like ABS or polycarbonate
- Metal Epoxy: Designed to bond and fill aluminum, steel, or copper
- Putty Epoxy Sticks: Great for shaping, filling holes, or underwater repairs
Common Sealants and Garage Applications
- Silicone Sealant: Waterproof, flexible, and great for sealing windows, doors, and electrical components
- Polyurethane Sealant: Bonds well to concrete, wood, and metals—ideal for floor cracks or expansion joints
- Thread Sealant: Prevents leaks in threaded pipe fittings and fuel lines
Tips for Best Results
- Always prep the surface—clean, dry, and roughen if possible
- Mix epoxies thoroughly and apply within the working time
- Clamp or hold parts in place until fully cured
- Don’t use epoxies or sealants near high heat unless labeled for it
Final Thoughts
When used correctly, epoxies and sealants can handle everything from cosmetic repairs to structural fixes. Whether you're sealing a drip or bonding a bracket, having the right product on hand saves time, money, and frustration.
