Whilst we do prefer OSB or pre-coated plywood sometimes a customer requires a budget hoarding with traditional plain plywood. In this case we supplied a class 3 - B/C faced plywood. Most hoarding companies use C faced boards but the B standard we use is a cut above the rest. The example above only has primer applied. We would recommend 2 coats of acrylic white on top of this. White exterior primer and paint is available from most merchants or we can mix paint to any RAL colour.
