I'm getting close to finishing my Oslo project. I had a thought, could the paint be an issue? I filled the inside with Roxul to keep the mantel from getting hot so I might be able to put a picture or something on it. I'm planning on filling the 8" gap with sheet metal over the weekend. The face of the surround will be exposed to the heat coming off the stove. (broken image removed)(broken image removed)(broken image removed)
