We have purchased about 30 doors in multiple styles to refresh the look of a bathroom vanity, laundry area and kitchen. Eyebrows, squares and shaker-bead styles were manufactured, primed and delivered in less than 10 days.
My recommendation is to have them primed by the company, but lightly sand the doors with 180/220 grit sandpaper, vacuum and tack cloth BEFORE putting on the first coat of paint.
Also, we got the self closing, hidden hinges and are thrilled with them.
All in all, I recommend this company to replace your painted cabinet doors!
