How many types of glue do I need to do modelling?

The types of glue you'll need for modelling depends on the materials you plan to work with. Here are 5 common options:

1. PVA glue: This is a basic adhesive suitable for porous materials like paper, cardboard, and some porous plastics. You may know it as wood glue or Stickit.
2. Super glue: These are quick-setting cyanoacrylate glues ideal for bonding non-porous materials like plastics, rubbers, metals, and some hardwoods.
3. Epoxy resin: Two-part epoxy adhesives provide an extremely strong, waterproof bond suitable for metals, plastics, ceramics, wood and more. Great for structural modelling applications.
4. Plastic cement: Specially formulated to chemically weld together plastic model kit parts. Essential for scale modelling with polystyrene plastic.
5. Wood adhesive: For bonding wooden components. Look for aliphatic resin or polyurethane based wood glues.

For most general modelling, having a bottle of PVA glue and some super glue on hand will cover many basic needs. More specialised projects may require epoxy resin, plastic cement or other adhesives matched to the materials being used.
