Self combustion

Treatex , like other natural oil based products contains Linseed oil. If you use a mechanical sander to remove any freshly applied linseed oil based product, you should empty the sawdust out of the machine on a regular basis as there is a small but possible risk of self combustion.


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 high qulaity micrfibre 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.

*Natural can be used as a top coat with Spruce Colour Tone to achieve a pure bright white (see: Hardwax Oil Natural).
