How to Apply Primer to Cabinets

Create a new ambiance in your kitchen by painting your old cabinets. Preparing the cabinets properly is essential to creating a smooth, evenly painted finished product. Cleaning them thoroughly to remove old wax finishes and grime will encourage the paint to adhere evenly. Cabinets usually also require sanding and a coat of primer before you can paint them -- particularly if they were previously stained. As soon as the primer dries completely you can apply paint.

Instructions

    • 1

      Remove all removable hardware from the cabinets, such as handles, latches and hinges.

    • 2

      Mix a trisodium phosphate cleaner with water according to the product's packaging directions. Put on rubber gloves. Use the TSP solution to scrub the entire cabinet.

    • 3

      Remove the wax finish, if applicable, with an ammonia-based cleaner. Allow the cabinet to thoroughly dry from the cleaning.

    • 4

      Sand the cabinet with 80-grit sandpaper in the direction of the wood's grain. Repeat with 120-grit sandpaper. Continue sanding until the cabinet is very smooth.

    • 5

      Use a nylon-polyester brush to apply an oil-based brushing putty on cabinets made of open-grained wood. These include mahogany, oak, ash and hickory. The brushing putty works like primer, but it also fills in tiny gaps in the open-grained surface to provide a smoother finish.

    • 6

      Use an oil-based primer for cabinets made from woods that have a tight grain, such as maple. Dip a small roller into the primer and apply it to the cabinets. Brush the primer after finishing each section to smooth it out more evenly.

    • 7

      Allow the primer to dry for 24 hours. If you used brushing putty, sand the cabinet again with 120-grit sandpaper.
