Treatex Bangkirai Oil is an exterior wood finish which provides long term protection from UV rays and weather damage. This product is manufactured on a base of natural sustainable raw materials: sunflower oil, soybean oil and rapeseed oil. Treatex Bangkirai Oil is designed for use on timbers like bangkirai, yellow balau, karri, massaranduba, iroko, and ipe. It is not suitable for timbers which contain tannins, such as oak. Treatex Bangkirai Oil is very hard wearing, which makes it the ideal finish for decking, garden furniture and other exterior joinery.
