A Guide to Treating Exterior Wood 

If you’ve used exterior wood on a project, you’ll need to treat it to provide protection from the elements.  
While timber is extremely hardwearing, and will last a long time, plus few things match its natural beauty, excessive exposure to moisture or insect activity can lead to problems if it’s left untreated.  
Rot is another potential issue, as is general tear, wear and decay. Equally, you may wish to freshen up a tired-looking timber piece. 
So we’re often asked how to treat exterior wood. And there are a number of different methods, which we look into in a little more detail here. 
Exterior Wood Treatments

Exterior Wood Treatment Oil 

Wood oils nourish your timber and can give worn wood a new lease of life by reviving wooden surfaces to their natural colour. Weathering saps timber of its natural oils, potentially leading to splitting, warping and drying, while wood treatment oils replace them. You’ll be left with a robust, waterproof finish, and could choose to have enhanced water resistance with an oil/resin blend, or a product with UV filters to protect against sun damage. 

Exterior Wood Varnish 

Time and weathering can result in cracks, blisters or peeling paint on woodwork. Exterior wood varnish is particularly good on doors and their frames, as well as wooden gates and window frames to safeguard against UV light and moisture penetration. Good varnish for wood is weather resistant, offering continuous protection, and is especially good if the wood has previously been treated or stained. 
You’ll also get a rich colour and enhanced grain on your wood, while varnish comes in gloss, matt or satin finishes. You’ll need to prepare your surface well first, by sanding and by filling in any cracks. 

Exterior Wood Paint 

This is a quick, easy way to breathe new life into your wood with a fresh injection of colour. Equally, outdoor wood paint also means you keep fading, peeling and other wear at bay, while providing a rich colour palette. Exterior wood paint is ideal on items like planters, furniture, panels, sheds and other wooden structures. 
Again there’s great protection, from peeling, fading, and weathering. You’ll need to apply a good couple of coats, if not three. 

Exterior Wood Preserver 

Wood preservers are beneficial to use on sheds and fences, and they can be coloured or clear. Exterior wood preservative treatments help stop rot and decay as well as waterproofing, insect attack plus algae and mould. Meanwhile, you hold back potential damage from UV rays at the same time. You need to apply the wood preserve quite generously, and let it soak deep into your timber. You can add a fresh topcoat without sanding, plus an exterior paint coat if you wish. 

Exterior Wood Stain & Dye 

Exterior wood stains add a rich, deep colour as well as long-lasting, scuff-free protection from the elements and heavy foot traffic. Enhance your natural grain and take your pick from different colours as well as extra water repellence or a non-slip finish. You’ll see off peeling, blistering and cracking with wood dye and stains. Let it saturate deep into the wood – and bear in mind you’ll need to recoat every two or three years.
