Frequently Asked Questions

Many of our customers always have questions about our finishes and process. Read below to find your answer. Reach out to our experts at Sutherland Welles Ltd.® for any questions you may have.

Raw Tung Oil is a VERY SLOW drying oil. It takes upwards of 6 weeks for raw Tung oil to cure and often remains sticky during that 6 weeks.

Yes, it can be used on any porous stone, unglazed tile, and metalworks. It is best to use any relevant Sealer (check products for best usage) and fewer coats will be needed.

Yes, ALL of our finishes are considered inert and food safe after they are full cured for 30 days, except our Millie’s All Purpose Penetrating Tung Oil. Millie’s finish is the quickest to reach food safety usage, as it is formulated with Polymerized Tung Oil, Citrus solvent, and beeswax with no added driers making it usable once DRY, usually after just 3 days. This is great finish for salad bowls, cutting boards, and counters such as a kitchen island to be used as food prep.

Yes, the only difference is the UV and Mildecide additives between the two. They are fine to use indoors.

A natural White China Bristle brush (stainer-style, square tip) is best to use to apply our finishes, especially the film finishes in the Murdoch’s line. This brush is available on our online store. A short-napped, synthetic floor pad can be used for large floors. A Scotts blue shop towel can be used for small tight areas. It can also be sprayed using a HVLP sprayer to a achieve a light thin coating.
