Tung-Oil Floor Finishes
From contributor P:
Waterlox is a really good choice for a floor finish. The gloss version used to be marketed as gym floor finish but they widened their strategy to include woodworking. Waterlox contains polymerized tung oil and a high ratio of phenolic resin. Here's a quote from their website:
"The result of combining Tung oil (which inherently posses excellent water resistance, due to the double bond characteristics of its molecular chain) with phenolic resin yields a film that is comparable with polyurethanes, conversion varnishes, and other synthetic coatings for chemical resistance, with the added benefit of having excellent flexibility, substrate penetration, re-coatability and non-yellowing properties. Varnishes formulated in this manner will never chip, crack or peel and will remain elastic (flexible) over extended periods of time."
It's also easy to repair.
From contributor D:
Waterlox is an expensive finish for what it offers for protection. I would use catalyzed varnish before Waterlox for durability. Both contain high flash solvent and smell like hell. Catalyzed varnish, unlike Waterox, is extremely wear resistant. If you want a user friendly finish that is repairable I would use burnished tung oil penetrating finish. It is not as durable but can be replenished in just the traffic paths (no recoating wall to wall) as often as you need. I have costed out re-oiling the traffic paths every year versus removing furniture and screening and recoating every 5-7 years and the oil is less expensive over time and provides a fresh look every year. Surface finish looks worse every year until 5-7 years later you recoat it.
