Glue for Soft Wood Dowels

What glue re-fixes loose dowel joints in a heavy pedestal table?

For a heavy table whose legs are joined to the centre column by dowels that have gone loose and gaping, Selleys recommends Araldite Super Strong Epoxy Adhesive. The one instruction that matters more than the glue choice is this: remove the old adhesive first. Then glue, clamp the joint, and leave it alone while it cures.

The alternative Selleys names is Aquadhere Durabond, a polyurethane woodworking glue with excellent gap-filling properties. Given that your joints are described as gaping, Durabond is worth serious consideration — a gap is exactly the condition a PVA handles badly and a gap-filling glue handles well.

Why the old adhesive has to come out

This is the step people skip, and it is the reason a re-glued dowel joint comes loose again within a year. Old glue left in the dowel hole is what the new glue bonds to, and a fifty-year-old dried PVA plug is a much weaker substrate than clean timber. Removing it lets the new adhesive bond to the wood itself.

On a pedestal table the loading makes this worse. Three legs carry the whole weight of the top through two dowels each, and every time someone leans on the table the joint is levered. There is no slack in the design for a half-strength bond.

Figures are indicative data only and are not intended for the preparation of specifications.

The 2 to 3 minute working life is the number to plan around. Once you mix the two parts you have less time than it takes to dry-fit three legs. Mix small batches and do one joint at a time — dry-assemble everything first, mark the alignment, and only then mix glue for the joint you are about to close.

Handling strength comes at 30 minutes, but that is not the same as done. Do not apply undue strain to the bond at that point; hold the join in place with tapes or weights if clamping is awkward. Maximum strength is reached at 16 hours, and full strength development takes longer in cold weather. Selleys' answer to this question says to allow 24 hours after gluing, which is a comfortable margin over the data sheet figure — on a table that will carry real weight, giving it the full day rather than the minimum is sensible.

Aquadhere Durabond — the gap-filling option

Durabond is a solvent-free, moisture-curing polyurethane. It expands and foams as it cures, which is what lets it fill the gaps in a slack dowel hole rather than running out of them. It is sandable, paintable and stainable once cured, and it bonds a broad range of materials — timbers, MDF, metal, ceramics, glass, masonry and most plastics.

The foaming behaviour cuts both ways. On high humidity or damp surfaces the foaming increases, and excessive foaming produces a weakened joint. The counter is clamping: tighter clamping reduces foaming and improves the bond. Clamp or weight the joint firmly for about 4 hours until initial set, and expect maximum strength at 24 hours, depending on humidity and how porous the timber is.

Because it is moisture-curing, Durabond needs atmospheric moisture to work. If the timber is very dry or very porous, wipe the surface with a damp cloth for one minute before bonding. Do not apply it below 5°C.

How to redo the joints

1. Take the joint apart and get all the old adhesive off both the dowel and the inside of the hole, so the new glue can bond to bare timber.
2. Dry-assemble the leg and check the fit. Mark the orientation so you are not solving alignment problems with glue going off in the joint.
3. Set up your clamps before you mix anything, so they are ready to close.
4. With Araldite Super Strong: dispense equal parts of both liquids onto a clean disposable surface and mix thoroughly with a spatula. With Durabond: if the timber is very dry, wipe it with a damp cloth for a minute first.
5. Apply, assemble and clamp immediately. Work one joint at a time.
6. Leave the epoxy clamped. Handling strength is at 30 minutes; do not stress the joint before then. Durabond needs about 4 hours of firm clamping for initial set.
7. Give the table 24 hours before it carries weight again.

Limitations worth knowing

• Aquadhere Durabond is not recommended for structural applications, and is not suitable for below-waterline use or continuous submersion. It is not recommended for polyethylene or polypropylene plastics.
• Durabond requires atmospheric moisture to cure, so its use may be restricted in dry conditions, and it cannot be applied below 5°C.
• Durabond is susceptible to contamination from iron and steel — nails and similar — which can cause brown or black staining, and the tannins in many timbers can discolour it too. On a visible furniture joint that matters.
• Araldite Super Strong's working life is only 2–3 minutes at 20°C. Mixing more than you can place in that time wastes it.

Safety: Durabond is the most heavily classified adhesive on this page

The two products offered here are not comparable on hazard, and on an indoor furniture repair that is worth knowing before you choose.

Product	Classification
Aquadhere Durabond	Danger — H334 may cause allergy or asthma symptoms or breathing difficulties if inhaled (Category 1A); H351 suspected of causing cancer; H373 may cause damage to organs through prolonged or repeated exposure; H332 harmful if inhaled; H335 respiratory irritation; H317 skin sensitisation (1A); H315; H319
Araldite Super Strong	Part A Warning — H315, H319, H317. Part B, hardener, Danger — H314 severe skin burns, Category 1 eye damage, H317
Aquadhere Exterior	Not classified as hazardous under Safe Work Australia GHS 7

What that means for a table in a room

Five of Durabond's eight classifications concern the respiratory tract, and ventilation is the control. H334 is respiratory sensitisation at Category 1A: the immune system learns to react, the change is generally permanent, and afterwards an exposure far below the one that sensitised you can provoke wheeze, chest tightness or an asthma attack. It develops from repeated exposure at levels that feel like nothing at the time.

The specific problem here is that Durabond keeps working after you walk away. It is moisture-curing and it foams, and the method above has you clamp the joint firmly for about four hours and leave it 24 hours before loading. Pedestal tables get repaired where they live — a dining room, a closed garage — and the room is usually shut up while the clamps are on. Ventilate the space for the cure, not just for the five minutes you are applying glue. H373 and H351 are about accumulated exposure rather than one job, which is exactly what a shut room across a weekend supplies.

H317 at 1A and the epoxy's H314 both point at gloves. The method says to mix Araldite in small batches, one joint at a time — three legs means mixing three times, so three chances for neat hardener on skin. Part B causes severe skin burns. Use a spatula, wear nitrile gloves, and change them between joints.

If the holes are loose rather than genuinely gaping, you have a way out. Aquadhere Exterior is not classified as hazardous at all, and Aquadhere Quick Set carries only H317. Neither fills a gap the way a foaming polyurethane does, so the trade is real — but fresh dowels in clean holes remove the gap, and with it the reason to reach for Durabond.

Common questions

Epoxy or polyurethane — which should I use?

Selleys names Araldite Super Strong first for this repair. If the dowel holes are genuinely gaping rather than merely loose, Aquadhere Durabond's gap-filling and expansion give it the advantage, provided you clamp firmly to keep the foaming under control.

Do I really need to clamp?

Yes. Selleys' advice for this repair is to clamp after gluing. With Durabond it is not optional — tighter clamping directly reduces foaming and produces a better bond.

How long before the table can be used?

Araldite Super Strong reaches maximum strength at 16 hours per its data sheet, and Selleys' advice for this repair is to allow 24 hours. Durabond attains maximum strength in 24 hours. Do not stress the joint before then.

What if I cannot get all the old glue out?

Get out as much as you can — the more bare timber the new adhesive touches, the stronger the joint. Selleys is explicit that removing old adhesive is what allows the glue to bond well to the timber surfaces.

Will Durabond's foaming push the joint apart?

It can if the joint is not held. That is why firm clamping or weighting for about 4 hours is specified. On high humidity and damp surfaces foaming increases and a loosely held joint will be weakened.

How do I clean up the squeeze-out?

Durabond expands as it dries, so trim or sand the excess once it has cured. Because it is sandable, paintable and stainable, a tidy trim will finish invisibly on most timbers.

Is Araldite strong enough for a heavy table?

Its published bond strength is up to 150 kg/cm² when fully cured on clean, abraded surfaces, and it is listed as suitable for wood. The strength depends on the preparation — clean, bare timber and a properly clamped joint.

Is there another Araldite that gives me more working time?

Yes. Araldite Extra Time has a longer working window, with an initial bond time of 6–8 hours and maximum strength at 24–72 hours. It suits complex assemblies where three legs have to go together at once.

What if the dowels themselves are damaged?

Replace them. No adhesive compensates for a split or crushed dowel, and a fresh dowel in a clean hole gives the glue the bonding area it was designed for.
