Introduction To Treating Wood

Whether it is wooden decking, furniture, sheds or barns, the only way to keep your wooden structures good and free from rot is to treat them. Regular maintenance of wooden structures will help ensure you can enjoy your prized possessions for longer. In this article, we aim to provide a comprehensive introduction to treating wood, to help you along the way. So for information on how to protect wood outside, read on!

Types Of Outdoor Wood

Wood is often used externally on features such as cladding, fencing, pergolas, decking, sheds and sleepers. Whether you are using softwood, hardwood, or even marine wood, you will need to know how to treat wood to prevent damage from the elements. So let’s start by taking a look at how to treat wood for outdoors.

How To Treat Untreated Wood For Outdoor Use

When it comes to treating wood for outdoor use, proper preparation is key. New wood is particularly vulnerable to sun and moisture during its first year. Therefore, we recommend using Owatrol Seasonite. Using this to treat new timber, allows the new wood to weather naturally in its first year without damage. It is suitable for use on pressure treated woods, softwoods and hardwoods and can be used both horizontally and vertically, making it ideal for use in the garden. Please note that Seasonite is not suitable for use on oak. If you have oak that requires an outdoor wood treatment, please contact our Technical team for further advice.

Alternatively, Centrecoat R26 is a powerful and effective pretreatment for new tanalised timber prior to the application of paints or stains.

How To Prepare Outdoor Wood

First on the list is to clean the wood. Failure to clean and wipe down the wooden surface could lead to the finishing agent not holding or sticking sufficiently.

If the surface you are coating has previously been painted with wood oils, or has been damaged by UV rays, we would recommend using Owatrol Aquanett. It is ideal for removing oils and mill glaze from both new and old weathered exterior timber. This can then be followed with Owatrol Net-trol.

Owatrol Net-trol is a powerful wood cleaner and restorer. It is the ideal preparation to treating outdoor wood.  It will save you both time and effort by effortlessly removing both the surface and ground in dirt in as little as 15 minutes without the need for sanding. Furthermore, Net-trol is also biodegradable and does not contain solvents or bleach, meaning it’s not harmful to plants and shrubs  and is therefore safe to use in the garden.

If you are finishing decking, then Osmo Decking Cleaner is ideal. It has a special concentrated dilution for cleaning untreated or oiled wooden decking and garden furniture. Osmo Decking Cleaner ensures the surface becomes resistant against soiling and water.

Treating Wood: What Finishes Can You Achieve?

There are various finishes available depending on the type of look you want. From wood stains, oils, solid colour paints or varnishes, you can give your exterior project the protection it requires without having to lose any of the beauty.

Wood Stain

A wood stain is a great way to protect exterior wood, whilst also making it look stunning! It is important to check the wood stain you choose is suitable for the type of wood you are preparing, as some types of wood are more resinous than others. If you rush into coating resinous or exotic woods, you risk the coating causing a reaction to the wood’s surface.

Below are just a few of the wood stains available from Promain:
