NATUROIL oil finishes dry by a process called oxidation. The oxidation process is accelerated by the incorporation of driers in the coating. The drying starts at the surface and gradually progresses to the bottom layer of the film.
Frying refers to the softening, swelling and wrinkling of the dry coating by solvents upon recoat. All oxidative drying coatings are prone to “frying” also referred to as “lifting”.
Like all oxidative drying coatings, NATUROIL has a recoat window. If NATUROIL is coated soon after application (e.g. within 4-6 hours – if dry enough to walk on) or after it is fully cured (e.g. after one week) frying is unlikely to occur. Frying is most likely to occur during the period 12 to 72 hours after application. Open grain timber will increase the risk of frying due to semi-dried oil deep in the grain.
The following points will maximise the potential for frying upon recoat:
