Birch Dryden WoodOil

Birch Dryden WoodOil is a water-repellent, non-filming timber protector. It is a deeply penetrating oil that utilises an ultraviolet, stable fungicide. Dryden WoodOil's water repelling properties prevent the absorption of water deep into the timber, reducing excessive warping, cupping, and splitting of timber, thus extending the service life of those timbers.

Dryden WoodOil is made in New Zealand and specially designed for our conditions. It is suitable to be applied to wood cladding, shingle roofs and fencing, including all wood items like decks, outdoor furniture and specific interior finishing, on all species of timber and wood surfaces, old or new, rough or smooth.

Dryden WoodOil is available in a range of colours to help maintain and complement timber character and colour without hiding the grain, and is also available in clear for natural finishing, allowing timbers to silver and weather but maintain water repellency.

Dryden WoodOil applies easily and rapidly and can be applied by:

  • Speed brush: Pal brand for most surfaces.
  • Spray: Use airless spray equipment. Choose a nozzle to deliver a low-pressure coarse spray.
  • Brush: For uneven or rough surfaces, a wide good quality bristle brush is best.

If you find excess absorption into some timbers, we recommend that you change the application style/method to achieve the correct coverage rate.
