Armourflex UV Protection Oil contains a careful balance of UV absorbers and antioxidants, designed to capture the damaging UV rays from the sun and dissipate them safely as heat. In this way, the UV Oil is able to defend the wood against greying and impart a subtle, enhanced warmth to its appearance. As a sacrificial product, the coating will become less effective over time (approx. 2 years depending on elevation and weather conditions), but a fresh top up coat can easily be reapplied. Water-repellent oil and resins help to protect against warping and twisting, and active ingredients at the surface aid in the prevention of mould, fungi, and algae growth. Together, these form a microporous shield suitable for all exterior wood, especially external joinery, luxury cabins and wooden cladding.
