Epoxy quartz countertops, also known as engineered stone, have become an increasingly popular option for kitchen and bathroom countertops in recent years. Though durable, stylish, and low maintenance, some homeowners wonder whether epoxy quartz can be refinished or recoated to restore its appearance or change its color. Here is what you need to know about epoxying quartz countertops.
What is Epoxy Quartz?
Epoxy quartz, or engineered stone, is made from ground natural quartz combined with polymer resins and pigments. The mixture is molded into slabs and cured under heat and pressure. This process makes the material non-porous, resistant to scratches, stains, and heat.
Compared to natural stone, epoxy quartz is more flexible in design. The resin allows more color and pattern consistency. It’s an ideal surface for busy kitchens and baths. Brands like Caesarstone, Silestone, and Cambria are popular options.
Can You Apply Epoxy to Quartz Countertops?
Unlike concrete and wood countertops, you cannot apply an epoxy coating directly onto quartz. The non-porous, factory finish prevents proper adhesion. Any epoxy or resin applied peels off easily leaving an uneven finish.
However, it is possible to apply new color, pattern, or texture to engineered stone through professional refinishing. This requires mechanical grinding followed by a polymer concrete overlay.
Professional Resurfacing of Quartz Countertops
With specialized tools and product knowledge, countertop professionals can mechanically grind the top layer off the quartz surface. This prepares it for a new overlay material. Polymer concrete is often used. It can be colored, textured, or stamped to completely change the look of the countertop.
This process is like performing concrete overlays on existing concrete. It renews the appearance and can hide damage like scratches or discoloration. Refinishing with concrete overlay costs approximately 40-50% of full countertop replacement.
What is the Process of Refinishing Quartz?
The process of resurfacing quartz countertops involves:
- Cleaning – The countertop is deeply cleaned to remove waxes, sealers, oils. This ensures proper bonding.
- Grinding – Using specialty grinding tools and vacuum systems, the top layer of the quartz is removed to expose a fresh surface for bonding.
- Overlay – A polymer-modified concrete overlay is troweled on and shaped to the desired texture and contour. Colorants and stamps can add more design.
- Sealing – Once cured, the overlay is sealed for protection and easy cleaning.
Professional installers have the skills to match details like edges and seams. The result is a completely refreshed countertop surface.
Benefits of Refinishing Quartz Countertops
- Cost savings – Extends lifespan at a fraction of replacement cost
- Customization – Change color, finish, and pattern
- Quick installation – Requires just 1-3 days with no demolition
- Sustainability – Avoids landfill waste from countertop tear-out
Should You Epoxy Quartz Countertops Yourself?
It is not recommended for DIYers to epoxy quartz countertops. The process requires commercial tools, bonding expertise, and finishing skills. Improper preparation or incompatible materials can cause the overlay to delaminate quickly.
For those set on a DIY project, consider concrete resurfacing kits made for quartz overlays. They provide pre-measured ingredients and detailed instructions. However, results still require skillful application. Unless you have concrete finishing experience, hire a professional installer for reliable results.
Maintain Your Epoxy Quartz Countertops
To keep your countertops looking fresh, follow these care tips:
- Clean spills quickly to prevent staining, especially oils and acids.
- Use a gentle cleaner and soft sponge or cloth. Avoid abrasive pads.
- Reseal concrete overlays annually to protect the finish.
- Don’t cut food directly on the surface. Always use a cutting board.
- Install trivets or hot pads under hot pots and pans.
Conclusion
While epoxy resin does not adhere directly to quartz, resurfacing sealers like polymer concrete make it possible to refinish engineered stone countertops. With professional installation, homeowners can renew the appearance of their quartz surfaces for design flexibility and cost savings versus replacement. Proper care will keep the overlay looking like new for many years.
