Buying advice: adhesives
- Porous materials like wood, paper and fabric bond well with water-based glues. Non-porous ones like metal, glass and most plastics need epoxy, cyanoacrylate or a polyurethane adhesive. Polyethylene and polypropylene resist almost everything, so check the label lists them.
- Thin glues need parts that meet closely. If the joint is loose or the surfaces are uneven, epoxy or polyurethane glue fills the gap and still holds.
- Fast-setting glue is convenient for small fixes but leaves no time to adjust a big assembly. For furniture and glue-ups, a longer open time is worth more than speed.
- Standard PVA softens with moisture. For outdoor projects, cutting boards or anything washed often, look for a water-resistant (Type II) or waterproof (Type I) rating, or use epoxy.
- Once opened, super glue and some epoxies thicken within months. Smaller bottles that you finish quickly often work out cheaper than a big one that goes off.
