Guide to the Application of Glue for Metal to Wood
Here we will help and show you how to attach metal to wood. Before you start applying any glue to a surface, you first need to make sure the adhesive you are going to use is meant to bond metal to wood. This means that you need to read the label on the product very carefully, as not all adhesives can be used to bond metal to wood. All three of the glue products we have reviewed above are all intended for bonding wood to metal, or plastics, ceramics, and a whole lot more.
- WorkSpace: You first need to prepare your workspace and ensure that the area is clean and dry and all the equipment you need is near at hand
- Wood: Remove all dust, grease, paint, or oil from the wood surface and make sure it is dry. Tape places off where you the glue should not go
- Metal: Ensure the metal surface is clean from all dust, oil, paint, or rust, then using 120-grit sandpaper roughen the metal surface slightly to allow the epoxy to grab onto the surface
The application of the Super Glue differs from that of the Epoxy Glue, so we will be guiding you through the application for both types of glue.
- Just hold the container in your hand and squeeze the sides of the bottle
- Apply a small amount of the glue to only one of the surfaces
- Now join the metal to the wood and grip together for around one minute
- Allow the job to stand for around five minutes to make sure the bond is secure
- Mix the resin with the hardener normally at a ratio of 1:1 onto a clean, dry, and disposable surface or container
- Apply to a surface within five minutes
- Now join the metal to the wood and if the job requires clamping, clamp the two items together
- Leave for 30 minutes, and it will thoroughly cure within 24 hours
Frequently Asked Questions
Can You Use Ordinary Wood Glue to Bond Wood to Metal?
This is not a good idea because ordinary wood glue is specially designed to be used on porous materials, and metal is not porous, so the bond will not be effective.

First, all surfaces should be cleaned and then left to dry thoroughly. Apply the adhesive as directed on the container and leave the glue to set completely. Always follow the instructions from the manufacturer.
Can Super Glue Be Used to Glue Wood to Metal?

What Is Wrong if the Super Glue Does Not Bond?
Make sure that both surfaces are clean and dry; we recommend that you use some acetone to remove all dirt, oil, or paint. Some woods contain dark tannic acid which will hinder the curing process, make use of some activator to remove all oily substances from the wood.
Are There Some Materials Where Super Glue Does Not Work?
Yes, you should not use super glue on polypropylene, plastics, polyethylene, and foam, as the chemicals in the glue will dissolve the material.
What Glue Can Be Used at Extremely Low Temperatures?
Most adhesives need to be applied when the temperature is 5 degrees or more and some adhesives only harden at higher temperatures.
Is Epoxy Adhesive Conductive?
The epoxy adhesive hardens to a dark grey color and does not conduct electricity.
What Can I Use to Take Off Any Excess Glue?
Before the adhesive cures and goes hard, you can use acetone to take off any residue. However, once it has cured you can only remove it by scraping, sanding, or cutting away.
