Painting cupboards: Any help would be greatly appreciated!!!!

Clean the surfaces with a slightly wet rag to remove any dirt.

If it has some oils use a bit of soap.

After that you'll need to sand them a bit with a 180 grit sandpaper.

Not too much; just to give a new finish a surface to adhere to well.

Now apply a new finish following the instructions on the package.

Good luck!

Rub down. Prime -Undercoat and then Topcoat with Satin Finish.......

Isn’t TLR the cleaner suggested for this? You need to make sure there’s no grease when you paint.

Make sure they are clean and dry. Remove the doors and hardware. Mark the doors and cabinets with tape where they go. Lightly sand the doors and cabinets to remove any gloss and roughen the surface for paint with 120- to 220-grit sandpaper. Use a tack cloth or damp rag to remove dust after sanding. Prime with a stain blocking primer like Zinsser 123, KILZ,or BIN and have it tinted to the color of the top coat. This will prevent dark or stained surfaces from showing through the top coat. Acrylic, or water-base, paints are low-fume and clean up easily with water. Alkyd, or oil-base, paints require good ventilation because the paint contains solvents that can irritate your lungs and make you feel sick. Alkyd options require mineral spirits for cleanup, but they provide a hard, durable paint finish. Whichever you use, buy the best-quality paint you can afford for a lasting kitchen cabinet finish. Seal with at least three coats with a water based polyurethane. Use a small foam roller and foam brush for a smooth finish.

How about chalk paint?
