Wipe cabinets down with a liquid sandpaper product on a cloth to clean off any grease and dirt and to make the the existing finish slightly rough and better able to hold a new finish, according to Utah State University Extension.
Take the cabinet doors off of the cabinets by unscrewing their hinges with a screwdriver or taking out the metal pins that hold the hinges in place.
Remove metal hardware, such as cabinet handles and hinges, from the cabinets unless you want to paint them red as well.
Place the cabinet doors on plastic sheets to protect the workspace from paint stains.
Sand wooden cabinets if they have any areas that are not smooth to create a good surface for the paint to adhere to.
Apply tape to the walls around the borders of the cabinets to protect them from paint stains.
Apply primer with a brush. Make sure to choose a primer that is compatible with the material the cabinets are made out of and with the type of red paint you purchased to use on the cabinets. Use a thick enough coat of primer to obscure the wood grain on wooden cabinets for the glossiest finish.
Allow the primer to dry thoroughly before painting the cabinets.
Double-check the paint label to make sure it is compatible with the type of primer on the cabinets.
Paint the cabinets with a glossy red paint using a brush. When painting wooden cabinets, paint in the same direction that the wood grain runs in. Don't forget the cabinet framework.
Allow the paint to dry thoroughly.
Paint the cabinets with another layer of the glossy red paint if the single coat of paint looks thin. Two coats of paint are better than one coat.
Allow the paint to dry and cure to a hard finish. This can take up to a week, depending on the type of paint. Oil paint can dry to a hard finish within 48 hours, while it can take up to seven days for acrylic-based paint to cure.
Reattach the hardware, such as handles and hinges to the cabinets, and put the doors back onto the cabinets.
