Best Wood Glue for Mitres: 2025 Expert Review
DR Joinery
Expert Joiner & Bespoke Fittings Specialist
Achieving a perfect mitre joint on skirting boards or architraves is one of the hallmarks of quality joinery. However, in older properties—typical of York's Victorian terraces—walls are rarely 90 degrees. This puts immense tension on mitre cuts, pulling them apart over time if the bond isn't solid.
Many DIYers rely solely on pins or nails, but without the right chemical bond, seasonal movement and central heating will eventually open those joints up. For a professional finish that lasts, you need the right adhesive strategy.
In this review, I've categorised three adhesive options I use for different scenarios: a classic PVA for structural strength, a rapid 'mitre mate' system for instant hold, and a bulk solution for large renovation projects.

Specs vs. The Real World
The Spec: "Instant Grab vs. Long-term Strength"
"Superglue (Cyanoacrylate) kits claim to replace wood glue entirely."
CA glue is brittle. If the skirting takes a knock (e.g. from a vacuum cleaner), the joint can crack. Real joiners often use a 'combo method': PVA in the centre for long-term strength, and activator glue on the edges to hold it tight whilst it sets.
The Spec: "Gap Filling Properties"
"Thick glues fill gaps in bad cuts."
Glue is an adhesive, not a filler. If your mitre is open because the wall is out of square, relying on glue to fill a 2mm gap looks poor. You should be scribing the timber or using a block plane to adjust the angle of the cut first.
My Top 3 Recommendations
Three options to cover different needs and budgets
Gorilla Wood Glue 118ml
Gorilla
This is your bread-and-butter D3 PVA glue. While it lacks the 'instant' grab of a two-part activator kit, it provides a far superior long-term bond that withstands impact and moisture. It is essential for the core of any joinery work.
The Good
- Incredibly strong long-term bond that absorbs vibration better than brittle superglues
- Water resistant (D3), making it suitable for mopping areas near skirting
- Dries natural wood colour, hiding minor squeeze-out lines
The Bad
- Requires clamping or pinning to hold whilst it dries
- Not suitable for 'instant' hold without mechanical fixings
Installer Tip:
For the strongest mitre, apply this PVA to the main face of the cut, but leave a small spot dry near the front edge for a dot of superglue. The superglue acts as a temporary clamp, holding the joint tight for 30 seconds whilst this PVA cures for the permanent bond.

When working with tricky external mitres on architraves where clamping is impossible, this two-part system is a lifesaver. The high viscosity glue doesn't run down the face of the board, and the activator sets it in 10 seconds flat.
The Good
- Comes as a twin pack so you aren't caught short mid-job
- High viscosity prevents runs and drips on finished timber
- Bonds in seconds - essential for 'returning' ends on skirting boards
The Bad
- Zero adjustment time once the surfaces touch - you must be accurate
- Strong chemical smell requires ventilation
Installer Tip:
Use the 'spray one, glue the other' technique. Spray activator on the right-hand mitre face, apply glue to the left-hand face. Align them carefully before touching them together. You effectively have one shot at this, so dry-fit twice, glue once.

If you are re-skirting a whole house or working on a large renovation in York, running out of activator is a constant headache. This bulk pack is the problem-solver for volume work, ensuring consistent results across multiple rooms at a very low unit cost.
The Good
- Exceptional value per unit - perfect for large fit-outs
- Ensures consistency across the job (same cure time everywhere)
- Reduces downtime from running to the merchant for more supplies
The Bad
- Quantity is likely overkill for a single room repair
- Shelf life can be limited if not used within a year
Installer Tip:
Store the spare bottles in a cool, dry place away from direct sunlight. In the van or a hot workshop, the activator can lose its pressure and the glue can thicken over time. Keep your stock fresh to ensure that 10-second grab stays reliable.
