The exterior staircase of our house is just under 25 years old. It's such a light colored granite. In terms of stone quality, the staircase is certainly still fine. In my opinion, it's too bright, too uneven, something darker and more monochromatic would suit the house and front door better. Perhaps this question/idea is completely pointless, but is there any way to redo the existing staircase by making it darker/more monochrome? Is it possible to put some kind of coating on it?
And if anyone has any advice on what kind of plaster or scraper to use to make this staircase really clean for once, to make all that green plaque, bleaching disappear.
