Treating your wooden gates, garage doors and external joinery
Like all exterior joinery, our wooden gates and garage doors need protecting from the extremes of the British climate, if they are to last for many years. There are many types of treatments available from paints to stains and oils.
If you decide to oil your wooden gates or doors then be aware that you could end up having to regularly apply additional coats of oil every 2-3 months to keep the timber in tip-top condition.
Of paints, steer away from ranch or fence paint as these are quite often made solely for rough sawn timber and will not adequately protect smooth planed timber. Gloss paints used to be the most common choice, but the main drawback with these products is that if water does penetrate the paintwork, then it won’t be able to escape effectively; if you’ve ever gone to repaint a window or similar that was previously coated in a gloss paint and found a paint shell on the exterior with rotten timber beneath it, then this is basically moisture that has gained access to the timber and not been able to be released.
Microporous? Moisture vapour permeable?
Our recommendations are microporous or moisture vapour permeable paints and stains; this basically means the paint or stains will allow the timber to breathe, stopping any moisture from entering the timber, whilst releasing any moisture already present. A good quality microporous paint or stain will also contain a UV (ultra violet) filter, to help protect against damage caused to the timber by sunlight. Amongst the many makes and brands available, our favoured is Sikkens, which we have over thirty years’ experience of using. If used correctly, and according to the manufacturers instructions, you could get up to three years’ usage before having to recoat your wooden gates or garage doors.
So which particuliar Sikkens product do we recommend?
As mentioned, our favorite is Sikkens which is a translucent stain (i.e. you can see the woodgrain underneath but it does have a tint which acts as a UV filter) which comes in a variety of shades.
The Sikkens products that we recommend, after speaking to the very helpful people at Sikkens’ Technical Advice centre, are Sikkens Cetol HLS Plus as the base coat, with Sikkens Filter 7 Plus for the top coats. For more information on both the mentioned products, you can visit Sikkens’ website at the links below, where you can find technical data and information on the various shades available.
You want a paint rather than a stain?
If you’re looking to paint your gates or doors rather than stain them, then there are a few paints that are micro-porous/moisture vapour permable. The most notable being International Paints and Johnstone Paints, but having said that with the experience we have of Sikkens, we would always recommend the aforementioned Sikkens over everything else!
