We are having a sunroom added onto our home. The sunroom has mahogany beams
which I am polyurethaning outside. To protect them, from possible
rainshowers, we covered them with a tarp for overnight. The tarp must have
had some water on the underside and a couple of the beams now show some
waterspots. I was hoping that they would disappear, however drying
overnight, the spots still show as much as they did yesterday.
Should water stain mahogany like this?
Should the waterspot disappear when dry?
I've tried sanding, but the spot must a lot deeper than I want to sand. How
can I get the waterspot out?
