How to apply Treatex Hardwax Oil Clear

Protect and enhance the natural beauty of wood with Treatex Hardwax Oil. Using over 40 years of experience in the timber and wood finishing industries our Hardwax Oil was developed to be user friendly, quick drying, easy to maintain and above all to provide a hard wearing and attractive finish. Treatex Hardwax Oil is manufactured on a base of natural sustainable raw materials including jojoba oil, linseed oil, sunflower oil, beeswax, candelilla wax and carnauba wax.


If the surface to be treated is rough or if a previous surface coating finish (e.g. varnish, lacquer, etc.) is present, sand to smooth bare wood with 80-120 grit sandpaper. Some previously oiled surfaces can be overcoated, without sanding. a trial application is essential when overcoating a previously oiled surface. 


If you are treating oily/dense timbers e.g. Iroko, Ipe, Teak, Jarrah, Merbau etc. thin the first coat of Treatex Hardwax Oil Clear by mixing with approximately 10% Treatex Thinner. This enables the product to properly penetrate into these types of timbers. Use a brush or roller to evenly apply Treatex Hardwax Oil allowing roughly 30g per m². On worktops and doors etc. pay particular attention to end grain (on end grain apply wet on wet until product is no longer absorbed by the wood). Allow to dry – maintaining warmth and ventilation will enable the surface to dry within 3-6 hours. Apply with a brush or roller a second coat of Treatex Hardwax Oil, again allowing roughly 30g per m². Allow to dry thoroughly overnight before the surface is lightly used. The surface will reach maximum hardness after a further 24 hours.

Insider Tips

If Treatex Hardwax Oil is applied too thickly, drying time will be increased. To speed up drying time raise the room temperature and increase air flow by opening doors and windows, or using a fan. 

Treatex brushes and rollers are available. Alternatively, use a short gloss pile roller or good quality brush. Tightly wrap a plastic bag around wet rollers and brushes to stop them drying out between coats. Wet brushes and rollers can be cleaned using white spirit. If you are using hardener then wet rollers and brushes will dry even if they are wrapped in a plastic bag and it will not be possible to clean them.
