Hi Mate,
Standard procedure (dependent on spec of manufacturer) Apply Base-coat onto EPS, rule with 12mm Notched Trowel (this will give you a 6mm base-coat) lay mesh on-top and the flatten the base coat. You can put a second coat over the top, Always ensure the Mesh is kept in the outer 3rd of the Base-coat
Any probs mate, please give me a call and I can talk it through with you
