Thread: Kauri pine floorboard finish - non-yellowing, natural satin

Oil it, easy to apply and easy maintenance.

:iagree

Tung oil was traditionally used on floors. Tung oil finish these days may represent a close or a looser definition of tung oil. You don't want a formulation with polyurethane in it, or anything which will give a build on the surface. Conservancy is about maintaining reversibility or repairability, a floor with a film will eventually require sanding and floor boards have a finite and very small number of sands in them over their possible lifetime. It's been a while, and maybe I'm confused about what I used on a build-in I did which I thought I finished with Feast Watson Floor oil (I used to use FW Floor Seal for furniture, but it is discontinued and floor oil seems to have replaced it) but I thought this product did give a build despite tech support and the blurb indication it has no PU in it. It does have additives to help it cure faster though. It might be one to try. To be absolutely certain though I would use something like Gilly's tung oil, which has no additives. The down side is it takes up to four weeks to cure, although light traffic is OK after 24 hours. Pure Tung Oil – Gilly's Australia

You'll have to scrape the floor if there is a previous coating on it though.
