Oak Porch Maintenance
Strictly speaking, the oak on your oak porch doesn’t need maintenance.
Oak is a very robust timber and can handle most weather conditions for years to come.
When you decide on having an oak porch, it can be coated with an exterior UV oil, normally in a choice of clear, natural (golden) or traditional (a darker oak).
Over time, the weather, especially the sun, will react with the oil and break it down. This may happen after several months or several years depending on which direction your porch faces and the amount of sun it receives.
You now have a choice. When you see a slight discolouration in the oak, a more silvery grey appearance, you could apply another coat of external UV oil or allow the oak porch to weather naturally.
This colour change is not detrimental to the oak. It is not a sign of rot and is purely a natural change in colour.
The change is a reaction between the UV rays of the sun reacting with a naturally present acid in the oak called ‘Tannin Acid’. This reaction causes the oak to turn silver grey.
It is personal choice how who you want your oak porch to look in the years that follow.
Try Osmo External UV Oil.
….”A natural oil-based and microporous finish which does not crack, flake, peel or blister. Water and dirt resistant, moisture regulating and reduces wood swelling and shrinkage. External elements of weathering fade the natural colour of the wood to a grey patina over time, but UV-Protection Oil has been developed to resist against this, whilst maintaining the wood’s natural appearance. Ideal for windows, doors, cladding, fencing and other vertically structured joinery to block the greying process of the wood by a UV-protected factor of 12 in comparison to untreated wood.”
