Make sure there’s no dust, dirt, oil or grease on your surface, says Dulux expert Nonkululeko Mcunu ( below). Shiny areas must first be sanded; then you can apply one coat of Dulux Supergrip All Surface Primer – which is ideal for surfaces that don’t need to work too hard, such as cupboard doors. This is not recommended for worktops. Wait until the Supergrip has dried then apply two coats of water-based Dulux Pearlglo enamel to the cupboard doors. Both products can be applied with a pressure sprayer (not an air sprayer – ask your hardware store), brush or roller. If you prefer a roller, use a sponge roller – it gives a smoother finish.
