What’s a low-odour finish for tongue and groove pine boards?
I just covered the walls in a basement room with tongue and groove pine boards. What would be a good, non-smelly finish for them? I do not mind having to reapply the finish every few years.
This is an easy one: Water-based polyurethane will be your best bet. It is virtually odourless, dries very quickly, is tough enough for walls, and cleans up well with soap and water. One or two coats, applied by brush or roller, should last for years. Touch-ups are easy as well.
