Rust-Oleum Doodle Wall is a smooth, hard finish that creates a unique, writeable-erasable surface. Once dry, simply use dry wipe markers* to draw or write messages and then erase. Application is easy and it has minimal odour making it safe to use indoors. Ideal for use on painted interior surfaces such as: Plasterboard, Hardboard, Wood, Cement and Metal. Application - Pour approximately half of Part B into Part A and stir until mixed in then add the remainder of Part B and stir thoroughly for about 2 minutes (until a uniform colour is achieved). We recommend using the enclosed microfibre roller which is designed to give a smooth, uniform finish, alternatively use a short-pile mohair roller. Use paint brush if necessary for edging. When applying this over darker coloured surfaces prepare first with a suitable white primer. Only one coat of Doodle Wall should be applied. Coverage - Up to 6m2.Drying Time - Dries to the touch in 4 hours. Note that once activated the workable pot life of this product is 4 hours.
