Hoping i could get some advice on a double sided stove install. Need to finish off using either supalux/promafour from what I can gather. One side is a 4m wide wall so dont want to use expensive board all along this stretch.
Can I use pink fireboard once far enough from the fire?
Should i use vitcas plaster in the vicinity of the fire then multifinish?
Can i blend the vitcas and multifinish without a visible join?

Hi, I wondered if its possible to ask you a question in relation to a thread i posted sometime ago
