Buying advice: adhesives

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
