How to use it

It works best on bare timber. Remove any closed finish, lightly sand porous finishes, and check the timber is dry and clean with moisture content below 18% and a temperature between 8 and 25 degrees Celsius. Treat timber that is susceptible to decay, mould or fungi with a preservative first. Used oily cloths and rags should be laid flat to dry before you throw them away, because oils that cure can heat up and in rare cases catch fire if they are left screwed up.
