Painting over quartz countertops is possible, but it requires some careful preparation and technique to achieve good results. Here is a detailed guide on how to successfully paint quartz countertops.

What is Quartz?

Quartz countertops, sometimes called engineered stone, are made from ground natural quartz crystals combined with resins and pigments. This creates a very hard, non-porous surface that is stain, scratch, and heat resistant.

Quartz is an increasingly popular countertop material due to its durability, appearance, and ease of maintenance. The resins allow quartz to come in a wide variety of colors and patterns that resemble natural stone.

Why Paint Quartz?

There are a few reasons why homeowners choose to paint their quartz countertops:

To update the color – Painting offers an affordable way to change the look compared to replacing the countertops.
To cover damage – Paint can mask scratches, chips, and stains on the surface.
For a specific look – Homeowners may want a custom color or effect that isn’t available with quartz slabs.

Painting quartz does alter the appearance of the pattern, so this only makes sense if you wish to completely change the look.

Preparation Tips

Proper preparation is crucial for getting paint to adhere correctly to the slick quartz surface. Here are some important steps:

Clean the Surface

Use a degreasing cleaner to remove any dirt, oils or residues from the countertop. Rinse thoroughly and let dry completely.

Lightly Sand the Quartz

Use 220-400 grit sandpaper to lightly scuff up the entire surface area being painted. This helps the paint bond better. Be careful not to sand too aggressively or you may damage the top.

Clean and Dry Again

Wipe the sanded areas carefully with a tack cloth to remove all dust. Let the surface dry completely before painting.

Use Adhesion Promoter

Applying an etching primer or adhesion promoter formulated for slick surfaces will improve paint bonding. Follow the product directions closely.

Tape Off Areas

Use painter’s tape to mask off any walls, backsplashes, edges and other areas you don’t want painted. This keeps the paint neatly on the countertop. Remove tape immediately after painting before the paint dries.

Choosing the Right Paint

The type of paint used is very important for achieving long-lasting results:

Use 100% acrylic latex paints designed for interior use. Oil-based paints and cheaper latex paints don’t bond as well and may peel quickly.
Look for cabinet, furniture, or countertop paints that offer maximum adhesion and durability.
Two-part epoxy paint kits provide the toughest, most water-resistant finish. But they have a learning curve to apply correctly.
Darker colors and lighter pastels adhere better than medium tones and whites on quartz.

Always test the paint on a scrap or inconspicuous area first to ensure proper bonding and appearance.

How to Paint Quartz Countertops

Once properly prepped, follow these steps for the painting process:

1. Apply Primer

For best results, use a bonding primer made for slick surfaces. Apply a thin, even layer with a small foam roller and let dry completely.

2. Lightly Sand Primer

Gently sand the primer coat with 400 grit sandpaper. This helps the topcoat bond better. Remove all sanding dust.

3. Paint Two Coats

Use a small foam roller to apply the topcoat paint in thin, even coats. Only paint as much area as you can cover before the paint begins to dry. Allow the first coat to dry completely before adding the second.

4. Allow Proper Curing Time

Acrylic latex paints may take a week or longer to fully cure and become scratch resistant on quartz. Avoid heavy use and cleaning during this time.

5. Reseal Yearly

Reapply a fresh coat of paint about once a year to maintain adhesion and prevent moisture damage. Proper prep work should still be done before repainting.

Tips for the Best Results Painting Quartz

Maintain a wet edge when painting to prevent lap marks and brush strokes. Work in small sections.
Roll the paint in different directions with each coat to ensure even coverage.
Apply thin coats and allow proper drying time between coats. Thick paint won’t bond well.
Pour paint into a paint tray rather than directly on the countertop. Accidental drips can run and dry quickly.
Paint all edges and cut-in work with high quality angled paint brushes before rolling.
Work slowly and carefully. Quartz does not absorb paint like other materials. Any drips or errors will remain on the surface.

Alternatives to Painting Quartz Countertops

If you decide paint isn’t the right solution, here are a few other options to change the look of quartz:

New quartz overlay – This involves adding a fresh layer of quartz over the existing countertop.
Tile overlay – Tile can be applied over quartz to completely transform the appearance.
Replace the countertops – For a complete change, new countertop slabs can be fabricated and installed.
Use an epoxy coating kit – High-performance clear epoxy can give the surface a glossy, wet look.

Conclusion

With the proper preparation and painting technique, quartz countertops can be painted to achieve a beautiful and unique look. The key is using adhesive bonding primers and paints formulated for slick surfaces. Maintaining the painted finish also requires diligent yearly touch-ups. For many homeowners, painting offers an affordable way to update the color and style of their quartz countertops.

Can You Paint Over Quartz Countertops? – FAQ

Here are answers to some frequently asked questions about painting quartz countertops:

Is all quartz the same when painting?

The specific quartz product, resin content, and finish can impact paint adhesion. Dense, polished slabs are most challenging. Paint bonding is easier on honed or textured quartz. Always test paint on your specific countertop.

What kinds of paint work best?

100% acrylic latex paints formulated for indoor use on furniture, cabinets, and countertops provide the best adhesion and durability. Oil-based paints don’t bond well and will peel.

How long does the paint last on quartz?

With proper preparation, high quality acrylic paints can last 3-5 years on quartz with occasional touch-ups. Epoxy paints can last even longer. UV exposure will degrade paint over time.

Can you paint just part of a quartz countertop?

It’s best to paint the entire continuous surface. Stopping paint partway can allow moisture penetration that may compromise adhesion. Full coverage also looks most natural.

What about painting quartz sinks and backsplashes?

Painting adjoining quartz surfaces like sinks and backsplashes is fine for a cohesive look. Use caution when painting near food surfaces.

How soon can I use the countertops after painting?

It’s best to avoid heavy use for 5-7 days to allow paint to fully cure. Hot pans and abrasive cleaners can damage fresh paint. Gentle use can resume after 24 hours.

Does the countertop pattern show through the paint?

Usually the solid colors and patterns of quartz make it an ideal base for painting. But some subtle imprints may still be visible. Primer helps block this.

Can I repaint quartz a different color?

Yes, you can repaint quartz countertops a different color after properly cleaning and sanding the previous finish to ensure paint adhesion.

Painting over quartz countertops can allow you to change up the look of your kitchen or bath on a budget. With some careful prep and painting technique, you can achieve professional, durable results. Be sure to use the right type of paint and allow proper cure time. Follow the steps above for long-lasting, quality paint finish on quartz.

Conclusion

Painting quartz countertops can allow you to refresh the look of your surfaces without the cost of full replacement. With proper products and techniques, you can achieve results that stand up well to daily use. The keys are taking time to prepare the slick quartz surface for painting, applying specialty bonding primers and paints, allowing adequate drying and cure time, and being diligent with yearly touch ups. Approach painting quartz countertops methodically and patiently, and you can be rewarded with beautiful, unique results. Just be aware of the maintenance required to keep your painted quartz counters looking freshly done.
