PVA (Polyvinyl acetate) glues are what most of us know as good old “white glue”. Common brands would be TiteBond All-Purpose White Glue and Elmers Glue All.
Why you should use it:
- Dries quickly.
- Easy water cleanup.
- Generally food-safe when cured.
- Inexpensive and economical.
Why you might not want to use it:
- Requires good clamping pressure.
- Designed to work on porous materials only.
- Most are not water poof.
- Not gap filling.
- Dries too quickly.
- Working with non-pourous materials.
What about Titebond II and III?
Titebond II adhesive is a water resistant “cross-linking PVA”. In other words a modified PVA glue that gives better water resistance.
Titebond III adhesive is a waterproof “advanced proprietary polymer”. Sounds like another modified PVA glue, but with even better water-resistance.
