  • Gerrry says:

    Can Vic ash be used as Facia boards?

    • ASH says:

      Vic Ash can be used as facia in 2 ways.
      1 – in the upcoming H3 treated clear – which will make it super durable externally
      2 – in untreated providing you are prepared to paint every year or two. without this, the appearance will deteriorate
