Wife really wants to use the black stove board instead of tiles or anything else to dress up around the stove. I am thinking of having a raised area using cement blocks sandwiched by hardiback sheets or something similar topped off with the black stove board. I know from experience that they really can not be cut or trimmed so I will be building it according to the dimensions of the stove board. My question is to the more experienced ,is this a good idea ? Will the board eventually be crushed by the stove's legs or something worse I am not thinking of ? The stove is an old vintage parlour stove on legs. Thanks for any response.
