When you refinish your existing cabinet doors, you get a whole new look without the astronomical costs normally associated with a kitchen remodel. It’s a much smarter way to update your space, especially if your cabinets are still in good condition. It doesn’t make sense to throw out perfectly good materials, just because you’re tired of the color.
Oh, where to begin? Let me start with 'watered down paint'. 25-50% before the material gets to the site? Impossible. You would basically be painting with water at that point. It would be less of a hassle, and cost, to simply use proper material. You would be forced to apply three coats instead of two, as the coverage would be horrible. Whatever cost you think might be saved in materials would be lost in labor.
