In practice
- The maker names the moisture sensitivity as an advantage in itself: it allows parts to be taken apart easily in antique restoration and musical instrument repair.
- After a night at 66 degrees, 3,207 psi remain at 59 percent wood failure.
- The difference from hide glue made up from granules: additives lower the gel point and extend the open time. In exchange no rubbed joint without clamps is possible, and the gram strength cannot be chosen.
- The maker states 24 months unopened. Look for a legible date of manufacture and use opened bottles up promptly; users report that natural protein glue deteriorates once the container is open.
- According to Franklin the joint stays under pressure for at least twelve hours; the clamping time depends on air and wood moisture.
- The ready-to-use hide glue is the practical choice where long open time is needed and the joint should be openable again later.
Technology and workmanship
Titebond wood glues come from Franklin International in Ohio, USA, and C.A. Götz jr. GmbH distributes them in Europe. Franklin sets out simple ground rules for working with them: the surfaces are clean, free of grease and dry, the wooden parts fit as closely as possible, the glue is applied generously on wood, and the joint is pressed together under pressure. If the glue has settled in the bottle, shake it well.
Titebond Original, II and III dry completely, without a soft residue in the joint that would absorb vibration. Titebond Original remains water-soluble, and its joint can be opened again with water and warmth. Titebond II and III are not water-soluble once cured; steam does not open these joints.
According to Franklin, Titebond Original Hide Glue (501) was the first hide glue in liquid, ready-to-use form. It is formulated like a classic hot hide glue but needs neither cooking nor heating, and it gives comfortable open time for application. The long drying time allows the parts to be positioned with care.
The bond is stronger than the wood itself and resists most solvents, varnishes, resins and sealers. It bonds wood, leather and other porous materials.
Once closed, the joint stays under pressure for at least 12 hours. It is worked above 10 °C and stored at no more than 21 °C, and it must not freeze. Once the glue has become thin and watery, it is no longer used.
Hide glue is water-soluble and a joint reopens under water, so it is not intended for bonds exposed to water.
Our experience
Titebond is our main adhesive in string instrument making. For violins we mostly reach for Titebond Original, because its joint can be opened again with water and warmth when a repair is needed later. For oily timber we recommend Titebond III Ultimate with the green label, with a test joint beforehand. With bog oak, which is hard to glue because of its high sulphur and salt content, Titebond III has proved the best of the Titebond glues for us.
Frequently asked questions
Is glue in the dispensing cap after shipping a defect?
No, as long as the cap was not pulled open this is normal, because the cap itself seals the bottle.
How do I undo a joint glued with Titebond II or III?
With a hot air gun and careful pressure, or with acetone as a last resort, protecting the surrounding varnish. Steam does not work with these two glues.
Which Titebond glue withstands 200 degrees, for instance at the bending iron?
None of the Titebond wood glues withstands around 200 °C without losing its properties. That temperature lies above the charring point even of Titebond III Ultimate.
Does Titebond hide glue need to be warmed?
No, it is ready to use and is applied without cooking or heating.
How long must the joint be clamped?
At least 12 hours under pressure.
How long does Titebond hide glue keep?
Well sealed, a very long time; the expiry date depends on the batch and is usually around two years. Once it has become thin and watery, it is spent.
