How to Paint Countertops: A Comprehensive Guide
Types of Countertops Suitable for Painting
When considering painting countertops, it’s important to understand which materials are most receptive to paint. Porous or sandable countertops make ideal candidates. These include:
- Laminate countertops
- Wood countertops
- Ceramic tile countertops
- Concrete countertops
Countertops Not Suitable for Painting
Certain countertop materials, such as quartz and natural stone, are not well-suited for painting. These materials have a low paint adhesion rate and are better suited for alternative treatments like sanding or buffing. Solid surface countertops are also not recommended for painting, as they tend to perform better when sanded and buffed.
Lifespan of Painted Countertops
Painted countertops can last for several years with proper care. However, the thin top layer of paint is susceptible to scratches and chips. Unlike solid surface or quartz countertops, which can be sanded down to remove imperfections, painted countertops require touch-ups or repainting. Lightly used painted bathroom counters may last up to two years before requiring a refresh.
Maintenance of Painted Countertops
Painted countertops require more care than other countertop materials. Avoid cutting directly on them and use a cutting board instead. Similarly, avoid sliding rough items across the surface. Extreme heat can also damage the paint, so use coasters for hot drinks and avoid placing hot pans directly on the countertop.
How Painted Countertops Work
Painted countertops consist of multiple layers of paint, creating a buffer zone to protect the base. If one layer becomes scratched or chipped, the underlying layers provide additional protection. The paint is also topped with a clear, hard polyurethane coating for added durability.
Safety Considerations for Painting Countertops
When using spray paint or coatings, it is crucial to work in a well-ventilated area. Wear a NIOSH-approved cartridge-style air respirator for safe breathing. Paper dust masks are not sufficient for this task.

Instructions for Painting Countertops
1. Remove or Cover Extraneous Items
Remove any items attached to the countertop that will not be painted, such as sinks or faucets. Wrap non-removable items with painter’s tape for protection.
2. Remove the Countertop (Recommended)
For optimal ventilation, remove the countertop and place it in a designated area like a garage or patio. If removal is not feasible, ensure there is adequate ventilation nearby.
3. Clean the Surface
Clean the countertop with TSP and warm water if it is greasy or dirty. Allow it to dry thoroughly before sanding.
4. Sand the Surface Twice
Sand the countertop lightly with #220 sandpaper to create a porous surface for paint adhesion. Remove dust with a shop vacuum and tack cloth. Repeat the process with finer #320 sandpaper, ensuring a smooth, glass-like finish.
5. Paint the Countertop
Apply light coats of spray paint, allowing each coat to dry or cure before applying the next. Matte sheen spray paint dries and cures quickly, usually within an hour.
6. Alternate Painting and Sanding
After every two coats of paint, lightly sand with #320 sandpaper and clean thoroughly. Aim for at least six coats of paint.
7. Apply the Top Coating
Spray the painted surface with clear polyurethane spray. Allow each coat to dry completely before applying another coat. Sand after every two coats to eliminate bubbles and peaks. Apply a minimum of three coats of polyurethane and finish with a final sanding for a satin finish.
FAQs
Can you change the color of quartz countertops?
Painting quartz countertops is not recommended due to poor paint adhesion. Sanding and buffing are more suitable alternatives for removing surface imperfections.
How do you refurbish a quartz countertop?
Clean quartz countertops with a solution of dish soap and water. Use rubbing alcohol for stain removal. Repair minor chips or cracks with adhesive or pigmented epoxy.
How can I update my kitchen countertops without replacing them?
Consider painting suitable countertop materials to change their appearance and conceal imperfections. Tiling or installing a granite or quartz overlay are other options for transforming the look of your countertops.
