Today in this post, we’ll tell you everything about treated pine decking. From what treated pine decking is and treatments to its appearance and pros and cons of treated pine decking, we’ve covered every detail.
Let’s start.
What is Treated Pine?
Pine is a sustainable, affordable, and fast-growing timber widely used for decking, fencing, pool framing, and many other things. Pine grows in many parts of the world, but it is sourced from its forests in Australia.
However, pine is raw wood, which is why it is not that durable and is prone to termites and rot. So, to make it more durable for outdoor use, chemical pine treatment has been done on it.
Different Pine Treatments Available For Decking
You may have heard of treated pine, but do you know that there are various treatments used for pine? Various chemicals are used today to create different types of treated pine for multiple purposes. It is done to make the pine rot-resistant.
Here are some of the common pine treatments:
- Water-borne Copper Chrome Arsenic [CCA]
- Copper Azole [CuAz]
- Light Organic Solvent Preservative [LOSP]
- Alkaline Copper Quaternary [ACQ]
- Oil-borne Creosote, Pigment Emulsified Creosote [PEC]
Apart from this, there are also other pine treatments available such as:
- Vascol Azure H1, H2, H3
- Protim Optimum ([LOSP) H3
- Tanalized Ecowood (TanE) H1, H2, H3, H4, H5
- Lifewood (CCA) H1, H2, H3, H4, H5, H6
- Protim (LOSP) H1, H2, H3
- NatureWood (ACQ) H1, H2, H3, H4, H5
- Tanalized C (CCA) H1, H2, H3, H4, H5, H6
In the above table, the ‘H’ denotes the different levels of chemical treatment used on the pine wood and what this can be used for. For example,
- H2: Provide protection against termites and can only be used indoors.
- H3: Provide protection against termites and rotting and can be used outdoors but above ground only.
- H4: This can be used outdoors for posts and garden edges.
- H5: This is for outdoor use, such as pergolas and decks.
- H6: this one is also for outdoor projects and can be in contact with salt water.
The process of pine chemical treatment is pretty much similar. First, the timber has been cut down to a specific size and length. After this, it is submerged into the chemical solution, and this is done by using a vacuum. After the treatment, it is drained off and ready to use for various purposes.
Treated Pine Appearance
So, what does a treated pine look like?
Treated pine looks golden white in colour. However, this can majorly depend on the chemicals used in the treatment process. The texture is somewhat grained, and its colour can vary on each piece of pine wood board. Remember that pine is a soft wood, which is why it is prone to knotholes. It is also susceptible to denting if it is not dried correctly.
