Glossy surfaces—whether trim, cabinets, or doors—can be tricky to repaint. Homeowners often ask if it’s possible to skip sanding, one of the most time-consuming steps. The short answer: Yes, but only if you use the right products and techniques. Here are answers to the most common questions.
1. Why is sanding recommended before painting glossy surfaces?
Sanding roughens the slick surface, giving new paint something to grip. Without sanding, paint may peel, chip, or fail to adhere properly.
2. Can I skip sanding completely?
Yes, but only if you use a bonding primer designed for slick or glossy surfaces. This type of primer allows paint to adhere without sanding.

3. What is a bonding primer, and how does it work?
Bonding primer chemically adheres to glossy surfaces such as tile, glass, laminate, or previously painted trim. It replaces sanding by creating a surface that paint can bond to.
4. Which glossy surfaces can be painted without sanding?
- Kitchen cabinets
- Interior trim and doors
- Gloss-painted walls
- Laminate furniture
- Glass or tile (with the right bonding primer)
5. Are there cases where sanding is still necessary?
Yes. If the surface is damaged, flaking, or uneven, light sanding helps smooth it out. Glossy paint in poor condition should always be sanded first.
6. What paint works best on glossy surfaces?
-
Latex paint is flexible and dries quickly, but requires primer.
-
Oil-based paint can adhere better to glossy areas but takes longer to dry.
- Always pair with primer for best results.
7. How do I prepare glossy surfaces before painting (without sanding)?
- Clean the surface with soap and water.
- Degrease with a mild cleaner or TSP substitute.
- Rinse and dry thoroughly.
- Apply a bonding primer.
- Paint with two thin, even coats.
8. How long will paint last if applied without sanding?
When paired with bonding primer, paint can last just as long as if you had sanded—provided the surface is properly cleaned and prepped.
9. Should I hire a professional painter for glossy surfaces?
Yes, especially for cabinets, trim, or large areas. Professionals know how to prep and prime for maximum durability. Submit our Painter Order Formto connect with trusted painters.
