Why timber stains differently?


Posted on April 13, 2016 by Paula Sanchez


At Oslek flooring we use the best imported European oak.shaft-oak-10384_960_720

As you might know, we are an environmental friendly company. Therefore, even though we use different species of Oak, our promise is towards sustainability and we use a non threatened species known as Quercus robur L. (in Latin Quercus = oak and  robur = strong timber).

Quercus robur is native of Asia minor, north Africa, the Caucasus and Europe. This species are a long lived trees meaning that they can reach up to 12m heigh, producing a long – lasting and durable heartwood. Moreover, it has an appealing grain marking, most when quarter sawn, and is characterised by having dark and light growth rings which makes it very attractive for flooring use.

We also display Australian oak, noted for its vigorous luxuriant growth, it can reach up to 20m and its trunk and branches are very thick and solid.

Lets get into the composition of timber!

The chemical composition of wood depends not only on the species but also the tree part, age, site conditions, geographical provenance etc.

The components that actually bothers us, as a Timber flooring company, is lignin, cellulose and hemicellulose. These components make the timber strong as the fibres of cellulose, lignin and hemicellulose bond well together.

Therefore, the coating goes over this structure, but….

Why does the same coating or stain make different (or  slightly different) colours on our lovely oak timber?

Every tree is different and so it is their composition in cellulose, lignin and hemicellulose! This makes for a one of a kind marking in the timber, which is unique like a fingerprint, and what gives the natural product it’s appeal.

When changing the ratios of these components (even ifQuercus_robur_-_La_Hulpe_(1b) they are the same species) the colour changes and so do the rings/features.

This is EXACTLY THE SAME as when you have a brother/ sister! you look similar but your are not the same!

Furthermore, the stress undertaken by the tree, light exposure and cyclical changes of expansion and contraction due to moisture varies affects the “paintability” of the timber. 

The staining process

Lots to take in! Lets keep moving forward to the considerations before coating timber:

The most important of our concerns are Moisture impermeability, the ability to resist U.V degradation, flexibility and heat reflection.

We take care of quality control before being shipped so it’s ready for delivery the moment it arrives in Australia.

Consequently, we make sure all the pre-coated/raw  timber we sell is in optimum conditions for you to use it!

Different stains

Oslek flooring have partnered with FIDDES for our staining process for raw boards.

If you have a particular look in mind that can’t be found in current range, we can always match your preferences and locally stain your requirements in our Mitcham factory.

We care about you and how you would like your floor to look like,

It’s important to have the right look for your project and we understand that individuals have unique colour requirements to meet your concepts.

As a result of staining and coating our engineered timber we obtain durable and gorgeous floors.

This makes it uniform and different at the same time as the features of the oak timber makes it unique.
