Hi There We are re-sheeting a workshop with Big 6 Fibre Cement panels and are painting these on site. The shed is in a heavily exposed rural location although only single story and low risk of impact/damage. Approx 300sqm single sided, or double if we paint internally. Final paint colour is to be decided but will be a recessive dark green in a low-sheen matt. Please could you advise the best product range for this?
