Hi I am looking for a Fire Retardant / Heat Resistant paint for the area around by Multi Fuel Burner, It is not for the Multi Fuel Burner but the Wall at the back of it, also the Concrete Slabs that it sits on. I am looking for 2 colours Slate Grey & Cream or Linen colour. I do not need that much of each, no more than 2.5L of each. I would prefer either Matt or Silk Matt finish. It would be fantastic if you could get back to me. Kind Regards Paul
