In practice
- Franklin gives a working temperature above 10 degrees Celsius for Titebond II Extend and storage at no more than 21 degrees.
- Checking the date of manufacture and buying a size that will actually be used up pays off with any glue.
- A note on classification: Franklin states only the ANSI/HPVA class for this line. The EN 204 D classes common in the trade do not come from the manufacturer.
- Joints that are meant to be opened again later take a glue whose joint can be released with water and warmth: hide glue or Titebond Original. Titebond II and III are not water-soluble once cured; such joints are opened with a hot air gun and careful pressure.
- Squeezed-out PVA seals the pores. Stain no longer penetrates there and leaves light patches. So do not wipe it wet: let it skin over and pare it off with a chisel.
- Clamping pressure by wood hardness: around 100 to 150 psi for softwood, 125 to 175 psi for medium, 175 to 250 psi for hardwood.
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.
Titebond II Extend (413) shares the properties of Titebond Extend and is also water resistant. Franklin names it as suitable for hot pressing and radio-frequency gluing. Clamping time is 30 to 45 minutes, 60 minutes for edges and facings. It is worked above 10 °C and stored at no more than 21 °C. Franklin describes the glue line as transparent.
The long open time suits large and many-part glue-ups, and as with Titebond II, steam does not open the cured joint.
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.
When another model suits you better
For interior work with long open time, Titebond Extend (910) is the right partner.
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.
How long is Titebond II Extend clamped?
30 to 45 minutes, 60 minutes for edges and facings.
