Or you could paint them in a week of evenings plus a weekend for around a hundred bucks like mortals do.

It's a lot of prep work to paint cabinets. Do you have a picture of yours to post?

We used an alkyd from Fine Paints of Europe called Eco to paint ours. We took all the doors off, labeled the hinges in ziplock bags.

To paint, we washed with powdered Dirtex, then sanded. Applied two coats of oil based primer, sanding in between. Then three coats of the paint, sanding in between the coats, as well as tacking off. My husband used a brush to paint, but some will want to spray. You will need a clean area to do this that is free of dust, etc. It took weeks and weeks because we have a pretty big kitchen, and we were doing it on my husband's weekends.

There are other paints that are less expensive to use, but we used this. It required a 16 hour dry time in between coats. If you are willing to put in the time, it will look good. I wouldn't personally paint maple, as it doesn't take stain or paint super well, but if you want to do this while you save for a kitchen makeover, and you have the time, I say go for it.

If you are planning on doing them yourself, then clean them once, and clean them twice. Sand them well, and wipe them down, and make sure the area is dust free. Prime with a high quality bonding sealing type primer. For paint, buy a paint that is meant for cabinets. It is usually oil enriched, but, has soap and water clean up. It takes longer between coats, than regular paint, and it dries to touch quickly, but, it takes a while to actually cure to its final harness. Cabinets are not painted with regular paint, if you want them to hold up..

If your cabinets are maple and in good condition, I would keep them, and look around your kitchen a bit. 9 times out of 10, it isnt the cabinets that make a kitchen look outdated. It is wall paint, or counters, or floors, etc etc. Before you paint them, post a picture here, and you will get opinions on it.

If you are really determined to go that route:

Check out General Finishes chalk paint (and no, it isn't real chalk paint).

Here is how I would expect a pro to spray paint kitchen cabinets. An amateur job should follow the same path. A brush painted job would differ slightly in that you wouldn't hang the doors to paint. You'd place them on a work table or easel instead. It's time intensive work, and should take 7-14 days to accomplish completely and cost between 7K-9K depending on kitchen size and amount of detail in cabinets.

Remove doors and drawer fronts.

Remove hinges and hardware.

Clean with TSP (tri-sodium phosphate)

RINSE and let dry.

Scrape any loose finish.

Fill any damaged spots or hardware holes that won't be reused.

Sand fill smooth.

Scuff sand the rest.

Tack off dust.

Hang in dust free paint booth with wires through hardware points.

Tack off dust again.

Spray with SHELLAC based primer.

Scuff sand again.

Tack off dust.

Spray with second coat of primer.

Spray with first finish coat of conversion varnish, or a polyurethane enamel if you are DIY.

Spray with second coat.

If glazing is to occur, that is next. (Don’t)

Spray with compatible clear over glaze

Add more molding or decorative details to boxes, filling nail holes and sanding smooth.

Repeat prep process with face frames and exposed cabinet sides using plastic to create a spray booth on site. If interiors are to be done, they are done before face frames and sides. Interiors are difficult, and add both time and expense to the job. Most interiors are laminate and don't accept paint well.

Allow everything to fully cure. That's 7-14 days.

Clean hinges and hardware and clear coat if you're keeping the old hardware.

Install new (or old) hinges and hardware.

Re-install doors and drawers and adjust for proper clearances.

If you are receiving or doing a job without this amount of effort, then you are not getting a quality job.
