Which glue works on fabric?
A washable fabric adhesive or a fusible bonding web — and never superglue, which reacts with cotton violently enough to burn.
Fabric is the hardest common substrate for adhesive because it flexes constantly, is washed in hot water with detergent, and is porous enough that glue soaks in and stiffens it. That is why the successful products are films that melt and re-solidify, or elastomers that stay soft, rather than anything rigid. There is also a genuine hazard here that manufacturers state on their own safety sheets: cyanoacrylate polymerises exothermically, and cotton and wool provide such a large surface area that the reaction runs away, producing smoke and enough heat to cause real skin burns. A drop of superglue on a cotton glove, a jumper sleeve or a tissue is the classic way people are injured by an adhesive at home.
The options, ranked
| Option | Good at | Bad at |
|---|---|---|
| Fusible bonding web | A hot-melt polymer film that melts between two layers under an iron; strong, even, washable and completely invisible. | Stiffens the fabric slightly, needs heat the material can survive, and is fiddly on curves. |
| Flexible fabric adhesive | Stays soft after curing and survives a normal wash, which ordinary PVA does not. | Slow to cure, can wick through thin fabric and show as a darker patch. |
| Temporary spray adhesive | Holds appliqué or a pattern in place while sewing, then washes out. | Deliberately temporary; overspray gets everywhere and it is not a repair. |
| Sewing | Still the only method that survives indefinite washing, flexes with the cloth and can be undone. | Takes longer and needs at least basic skill. |
Technique that changes the outcome
- Wash and dry the fabric first — dressing and softener on new cloth stop adhesive bonding
- Test on a hidden seam allowance; some adhesives darken pale fabrics permanently
- With fusible web, use the iron temperature the web specifies, not the fabric setting, and press rather than slide
- Let a glued repair cure fully before its first wash, usually 24-72 hours
What goes wrong
- Superglue on cotton or wool: the reaction is exothermic and can smoke and burn skin
- Ordinary PVA on anything that will be washed
- Gluing a load-bearing seam such as a strap or a waistband

Other glue and adhesive questions
| For | Use |
|---|---|
| Plastic | It depends entirely on which plastic — identify it first, because solvent cement is unbeatable on some and useless on others. |
| Polypropylene and polyethylene | Ordinary adhesives cannot wet these plastics at all. Use a polyolefin primer with cyanoacrylate, an MMA structural adhesive, or weld the plastic. |
| Wood | PVA wood glue for anything indoors; a water-resistant grade (Type I / D4) or polyurethane for anything that gets wet. |
| Metal | Two-part epoxy for anything structural, cyanoacrylate for small dry parts, and MMA where the surface cannot be properly prepared. |
| Ceramic and pottery | Two-part epoxy for anything that will be handled or loaded, cyanoacrylate for a clean break on a display piece — and neither is dishwasher-proof. |
| Shoes | A flexible shoe repair adhesive — polyurethane or a neoprene contact cement — never superglue, which cracks within a day of walking. |
| Glass | UV-cure glass adhesive for an invisible joint, clear epoxy where it must hold load, and neutral-cure silicone where it must stay flexible or wet. |
| PVC pipe | PVC solvent cement with its matching primer — and PVC, CPVC and ABS cements are not interchangeable. |
| Tiles | A cement-based thin-set in almost every case; ready-mixed tub adhesive only on small dry walls, never on floors or in showers. |
| Phone screens | A pre-cut adhesive gasket, or a flexible B-7000-type adhesive around the frame — superglue destroys screens and is the classic mistake. |
| Rubber | Contact cement for large flexible areas and rubber-toughened cyanoacrylate for small ones — but silicone and EPDM need a primer or they will not bond at all. |
| Outdoor and waterproof joints | Polyurethane or epoxy for rigid joints, MS polymer where the joint has to move — and check the water-resistance class rather than the word "waterproof". |
| Acrylic (Perspex, Plexiglas) | A solvent cement run into the joint by capillary action — not a tube adhesive, which will always look like a repair. |
| Concrete | Epoxy or a construction adhesive for bonding to it, and a chemical anchor resin — not glue — for anything that carries load. |
| Leather | Contact cement for a permanent flexible bond, or a leather-craft PVA to hold pieces while you stitch them. |
| Silicone | Effectively only more silicone, and even that needs a primer — and any silicone residue left on a surface stops everything else sticking too. |
| Paper | A glue stick or PVA for everyday work; wheat starch paste or methylcellulose for anything you want to survive — and never tape. |
| Foam | A foam-safe water-based adhesive or low-temperature hot melt — solvent adhesives dissolve polystyrene on contact. |
| Polycarbonate | A urethane or silicone adhesive is safest; solvent cements work but polycarbonate is unusually prone to stress cracking days later. |
