Why does the paint on my bathroom vanity keep peeling off?

Q: The paint on my bathroom vanity table bathroom Mirror factory— a 30-inch Brinkhill model made by WoodCrafters — has deteriorated, so I got replacement parts. The paint also peeled off. I now have another set of replacement parts. I don't want the paint to fail again, so I want to paint a new substitute. How can I best do this? Should I sand it first? Use primer? What is the best paint to use?
Answer: The paint should not peel off like the picture shows. The model you bought is sold by Home Depot, and the customer reviews on the website give it 3.9 stars (out of 5 stars), which looks good. However, if you scroll through some of the 700+ comments, you will find that most of the rave reviews are people who have just installed the dressing table, which is expected. When things are going well, people are unlikely to send comments in a few months or years. To understand what it feels like to use a product for a long time, you can usually learn a lot from negative reviews. For this model, about 20% of reviewers only gave one or two stars, and many of them complained about the same problem you encountered. In less than a year, sometimes just a few months, the paint began to peel off.
It’s great for the manufacturer to send replacement parts, but you certainly don’t want to continue acquiring and installing them. Before you invest in the time and materials required to refresh the replacement parts, consider whether the high humidity in the bathroom is the cause of the problem. All wood products will shrink and expand with the transfer of moisture in the air. If there is a large amount of shrinkage and expansion, the paint must also shrink and expand, otherwise it will crack and peel off. If water drips on the mirror, window, or wall at the end of the shower, the humidity is too high, at least part of the cause of the paint problem. Try a shorter or cooler shower, install a better bathroom fan, or open the door during the shower.bathroom Mirror factory
Generally, the fan should run in the shower and then run for 10 to 15 minutes. If you upgrade the fan, please purchase a fan that fits the size of your bathroom and meets the energy and efficiency standards of the Federal Energy Star Program (energystar.gov). If someone in your household forgets to turn the fan on or off, consider installing a fan with a humidity sensor.
You can also consider how to clean the cabinets. If you use cleaning fluid to wipe them, consider switching to a dry microfiber cloth. If you repaint, it is especially important to avoid liquid cleaners for 30 days, as water-based paint takes a long time to cure into a durable, washable film.
The Home Depot list says that the dressing table is made of particleboard and the front is natural wood, but there are no details about what paint and primer the manufacturer uses. Chelsey Knutson, a publicist at MasterBrand Cabinets, which owns WoodCrafters, said that the company’s policy is not to disclose suppliers, so she cannot tell what the paint or primer is on these vanity tables. But she does support cleaning with only dry cloth.
Frank Glowacki, the brand director of Rust-Oleum, did not elaborate on the finishes used in the factory. It is recommended that the surface be sanded and then cleaned with a non-foaming detergent. He recommended Krud Kutter concentrated cleaner/degreaser (Home Depot $6.58 per quart).
When the surface is dry, apply primer to all surfaces of the replacement part. Glowacki recommended BIN Shellac-Based White Interior Primer and Sealer (Home Depot $15.98 per quart), and he said that many professional cabinet repair agents use it. Apply with a brush or a very short, small-bristled mini roller (avoid foam). It will dry out within an hour, but let it stay overnight. To remove any burrs, lightly sand with 220 grit sandpaper before painting. Wipe clean. Then use any high-quality paint (including water-based paint) to apply the top coat.
If your paint layer is also peeling, your remaining option is to start over with bare wood. You can sand off the paint while using high-quality disposable respirators to protect your lungs. Or you can ask for replacement parts again-but please don't paint.
