We just replaced our front porch flooring with fir T&G. We stained it with Sikkens SRD semi-transparent. Love the color (ebony) but we were hoping for a more satin to semi-gloss finish rather than so matte. Plus I can tell it’s going to scratch easily. Is there anything I can apply over to harden it and give it a shinier finish? The porch is covered and faces East.
