So, our wood house we built in 2015 and only treated with Thompson's WaterSeal is looking pretty bad outside (lost color) and the inside floors need some love too. The inside walls and ceiling still look great.

Any recommendations for indoor floors and outside wood siding?

The local Sherwin Williams has "Barniz Marino" / marine vanish that was recommended by one friend. Anybody here have experience with anything that holds up well and is available in BZ?

.... or is this why everyone just paints wood houses? crazy
