Re: HELP-Mahogany porch floor--finish how???
We only use Ben Moore alkyd porch and deck paint. If you want a first-class job, you will back-paint the underside and the tongues and grooves first, install the flooring (stainless #8 ring-shank blind nailing through the tongues. you might have to pre-drill if you start to split a lot of tongues; some mahogany is harder than other) then have the floor sanded so it's seamlessly level with no proud corners- that's where the wear will start, at a sharp edge. Then after sanding, you paint the top surface 2 or 3 coats. The Moore paint has to be applied thin on the second & third coats as it tends to pool and then wrinkle.
Good luck, it makes a great porch floor and our customers are always satisfied with it.
