Glue Oily Wood like Oak, Teak, Maple, Cocobolo and many others. A How to Guide.

The Problem with Gluing Oily Woods

Most adhesives, even epoxies, do not glue oily wood well. This is because the saps and resins in the wood interfere with the bonding of the adhesive. However it is these saps and resins that make these woods durable and weather-resistant. A perfect exterior hardwood is almost by definition a very difficult wood to glue. It is almost glue proof by definition. To reliably glue oily wood is thus a traditional problem.

The traditional workaround to this problem has been two processes:

  • First sanding
  • Then cleaning the surfaces with solvents

All of this additional work prior to gluing of course. This workaround however is itself fraught with problems:

  • The solvents can cause the glue joint to fail. They will adversely affect the glue bonding to the oily wood
  • It can be extremely hard to properly sand and clean all surfaces on the inside of joints
  • The time required to perform these additional processes costs money. Further while the next part is being cleaned, the oils are leaching back to the surface on the parts already cleaned. All this helps to weaken the glue joint

How to Glue Oily Wood: The Solution

The real solution to glueing oily wood is of course to design a glue which is entirely compatible with the saps and resins within the wood. This glue should displace or absorb the oils, allowing it to penetrate into the wood to form a strong bond.

Steve Smith, a chemist, designed such a glue to overcome the problem of how to glue oily wood. It is a very flexible adhesive, excellent for gluing dissimilar woods and cross grain joints due to it’s ability to absorb stress and impact. That glue is Oak and Teak Epoxy Glue, also known for obvious reasons as the all woods glue. The simple process to ensure a durable joint to glue oily wood is described below:

How To glue Oily Wood

  1. Measure the Oak and Teak Epoxy out. It is a 1:1 mix ratio, so very easy to get right, and it is very forgiving of mix ratio errors
  2. Mix the Oak and Teak epoxy thoroughly. All two part adhesives require very thorough mixing to set properly. Wait around ten minutes until the mixed glue turns from white to amber before using it
  3. Do not clean the surfaces with solvents, they will be absorbed by the wood. This will interfere with the penetration of the glue and weaken the resulting joint. Remember – you can glue oily wood without solvents with the right glue – the all wood glue.
  4. Apply the Oak and Teak epoxy to both surfaces of the joint. Be patient and allow the wood to soak up as much as it wants to. End grain and porous woods such as the edges of plywood will soak up more. Scarf and Butt joints are especially prone to soaking up glue because of their end grain surfaces
  5. Now allow the wood to soak up the adhesive, deep penetration gives strong joints. Furthermore it stops the joint being starved of glue after assembly as the wood soaks the glue up then. Oak and Teak Epoxy has a long working time and you do not have to rush this stage
  6. Next clamp the joint using moderate pressure. Don’t use too much pressure as it will starve the joint of glue and weaken the joint
  7. Clean any excess glue from the joint area with paper towels. Avoid the use of solvents as they can penetrate the wood and weaken the joint
  8. Allow the glue to harden before stressing the joint. All Smiths Epoxy resins use their Dual Synergistic Catalyst™. This ensures a full dependable cure at temperatures as low as -2° C (28° F)

So what can I glue?

In addition to being able to glue oily wood such as Oak and Teak Epoxy glue will of course glue all normal woods that lesser glues can also bond reliably, but in addition it will bond the following woods that others will not, by simply following the instructions above:

So where can I buy it?

Make Wood Good sells Oak and Teak Epoxy from the UK across Europe

It is distributed across America by Smith and Co, and is also carried by a number of other distributors internationally.

I don’t believe you!

I don’t expect you to, the story sounds too good to be true., Would you believe some customers of this product; guitar makers, who use exotic woods and put the joints under constant stress with the strings? If someone can glue oily wood like cocobola under constant stress from strings – you can solve your problem too.

Michael Tobias Design (Guitar-maker)

(What we like about Smith & Co. products is that) They work–no glue failures: Better guitar finish adhesion; secure fingerboard glue joint. I have been recommending your glues for a long time…I would not dream of gluing on a fingerboard with anything other than your glue…and I doubt my finishes would be the same without…CPES

Or read the review in the March 2015 issue of Guitar maker Magazine:

Product Review – Guitar Maker March 2015

Jorge Palacios – Sculptor

I work the sculpture in wood for outdoors for over fifteen years and I think that your adhesive Oak & Teak is a high quality solution for sculptors and carvers that require advance preparation of a large size block. This great adhesive has allowed me, for its long curing time, to put with calm and precision all the pieces which compose the block; something I can´t do it with the majority of epoxy products.

I’m also happy because it’s not only almost transparent but, by its nature, allows me to have a line of glue especially thin. I would recommend to anyone who wanted to join woods difficult gluing or were considering using an adhesive for outdoor use.
