Overview of Glue Types
PVA Glue
The everyday hero for wood joints indoors. Easy to use and strong for wood-to-wood connections.
Epoxy Glue
The powerhouse for heavy-duty jobs and water-resistant connections. Ideal for filling gaps and repairs.
Polyurethane Glue
The versatile player that feels at home with various materials. Strong and water-resistant, perfect for outdoor projects.
Cyanoacrylate (Super Glue)
The quick savior for small repairs. Lightning-fast adhesion for precision work.
Animal Glue
The traditional choice for restorations and eco-conscious projects. Reversible and historically accurate.
Overview Table of Glue Types
| Glue Type | Description | Advantages | Disadvantages | Best Application |
|---|---|---|---|---|

| Epoxy Glue | Two-component glue | Very strong, fills gaps | Long curing time, complex to use | Heavy loads, boat building |
| Polyurethane Glue | Moisture-curing glue | Water-resistant, versatile | Foams up, can cause stains | Outdoor projects, various materials |
| Cyanoacrylate | Fast-acting glue | Very quick adhesion | Limited filling properties | Small repairs, precision work |
| Animal Glue | Natural protein glue | Reversible, traditional | Less strong than synthetic glues | Restoration, musical instruments |
Practical Tips and Step-by-Step Guides
Using PVA Glue
- Preparation: Ensure clean, dust-free surfaces.
- Application: Apply a thin, even layer on both surfaces to be glued.
- Clamping: Clamp the pieces together and remove excess glue with a damp cloth.
- Drying Time: Allow to dry for at least 30 minutes, preferably longer for maximum strength.
Mixing and Applying Epoxy Glue
- Mixing: Thoroughly mix equal parts of resin and hardener.
- Application: Quickly apply to both surfaces with a disposable brush.
- Clamping: Press the parts together and remove excess glue.
- Curing: Allow to cure according to instructions, usually 24 hours for full strength.
Working with Polyurethane Glue
- Preparation: Wear gloves and work in a well-ventilated area.
- Moistening: Lightly moisten one of the surfaces to be glued for faster curing.
- Application: Apply a thin layer on one surface.
- Clamping: Clamp tightly and remove foamed glue after curing.
