The 8 Best Wood Glues of 2024

Best Hot Glue For Wood
In recent years, I’ve become aware of the incredibly strong hot melt glues available. Surebonder Woodstik is by far my favorite.
It’s an extremely high bonding hot melt adhesive with a long open time. While formulated for wood, it’s also effective with metal, plastic and ceramic materials.
The manufacturer claims it can replace wood glue, but I’ve always used it in combination with other adhesives or fasteners to bend plywood for curve molds and reinforce rounded cabinets. This isn’t the same hot melt they use at the county crafts fair, I can assure you.
Color: Tan.
Open time: Fifteen seconds.
Waterproof: Yes.
Wet cleanup: Isopropyl alcohol for residue, hairdryer and putty knife for globs.
Pros
- Easily reversible with heat;
- Paintable;
- Waterproof;
- Non-toxic.
Cons
- Glue gun and power source needed;
- Messy;
- Really quick open time.

How Do Wood Glues Differ?
Chemistry and cure are the most significant factors that differentiate wood glues.
Common glues like Elmer’s craft glue, Titebond Original Wood Glue and Titebond III are all prepared by the polymerization of vinyl acetate, or PVAs. Hide glues are made from animal connective tissue, and polyurethane glues from, you guessed it, polyurethane.
PVA glues cure by evaporation or absorption of water into a substrate. Polyurethane glues cure by chemical reaction with moisture, and two-part epoxy glues cure by mixing hardener and resin together.
Exactly How Strong is Wood Glue?
It’s often said that wood glues today are stronger than the wood they join.
A typical wood can withstand a force between 200 and 1,000 pounds per square inch (PSI), while most wood glues can withstand between 3,000- and 4,000-PSI when fully cured. As a result, most woods, including the world’s hardiest ones, fail not at the glue joints but rather where the wood itself fails.
What’s The Best Way To Remove Wood Glue?
Sand it carefully with sandpaper. You could also try a heat gun to warm the glue so you can scrape it with a putty knife, though this may allow certain types to penetrate deeper into the wood grain.
