Quartz countertops are a popular choice for many homeowners due to their durability, aesthetics, and low maintenance. However, over time quartz may lose its original luster and start to look worn. This leads many quartz owners to wonder – can you reseal quartz countertops? The short answer is yes, quartz countertops can be resealed to restore their appearance and protect the surface. Here is a detailed look at resealing quartz countertops.
What is a Quartz Countertop Sealer?
A quartz countertop sealer is a protective coating that is applied to the surface of the quartz. Sealers work by bonding to the pores of the stone, forming an invisible barrier that prevents stains from penetrating into the quartz. They also enhance the natural look of the stone by providing a layer of gloss and shine.
There are two main types of sealers used for quartz countertops:
- Impregnating sealers – These penetrate below the surface and don’t leave any coating or residue on top. They won’t change the appearance of the quartz.
- Topical sealers – These coat the surface of the quartz, leaving a glossy, enhanced look. Topical sealers tend to be less durable than impregnating ones.
Why Reseal Quartz Countertops?
There are a few reasons why quartz countertops may need resealing:
- Renew the shine – Over time, quartz can lose its luster and appear dull. Resealing will restore the glossy finish.
- Prevent stains – Sealers help prevent oil, grease and other liquids from soaking into the stone. Resealing enhances these protective properties.
- Fill minor scratches – Very light surface scratches can be minimized by applying a fresh layer of sealer.
- Prepare for resale – Resealing improves the look of quartz countertops, which can add value before selling a home.
How Often to Reseal Quartz
Most quartz manufacturers recommend resealing every 1-2 years. Frequency depends on:
- Quality of original sealer used
- Amount of use and cleaning the counters get
- Exposure to sunlight, grease and other staining agents
Quartz in busy kitchens may need resealing annually. Reapply whenever water and oil stop beading on the surface.
Steps to Reseal Quartz Countertops
Resealing quartz countertops is a relatively simple DIY project. Here are the basic steps:
1. Clean the Surface
Use a granite cleaner and soft cloth to remove dirt, debris, oil and residue from the quartz. Rinse thoroughly and let dry completely.
2. Apply Sealer
Choose an impregnating sealer made for quartz and apply according to manufacturer directions. Typically a thin, even coating is spread across the surface using overlapping circular motions. Let the sealer penetration for 5-10 minutes.
3. Wipe and Buff Surface
Completely wipe away all excess sealer with clean, dry cloths before it dries. Buff to an even shine using a microfiber towel.
4. Allow Sealer to Cure
It takes 24-72 hours for the sealer to fully cure. Avoid spills and abrasive cleaning during this time.
5. Add Topical Coat (Optional)
An topical acrylic sealer can be applied on top of an impregnator for added shine and water resistance. Apply sparingly in thin, even coats.
Tips for Resealing Quartz Countertops
- Test cleaner and sealer on a small inconspicuous spot first to ensure compatibility with the quartz and avoid potential damage.
- Only apply sealer to completely clean and dry quartz or it won’t bond effectively.
- Thin coats of sealer provide better performance than thick, goopy applications that can get sticky.
- Ventilate the area well and wear gloves and eye protection when working with sealers.
- Resealing too often is unnecessary. Stick to the manufacturer’s recommendations.
FAQs About Resealing Quartz
Can you use granite sealer on quartz?
Yes, granite and quartz sealers are very similar and can be used interchangeably. Be sure to use a high quality sealer designed for stone countertops.
How long does sealer last on quartz?
On average, expect a sealer to last 1-2 years with proper care and maintenance. Reapply whenever moisture and oils stop beading on the surface.
Does sealing quartz change the color?
A good impregnating sealer that soaks into the stone won’t alter the color or finish. Topical coatings can slightly darken or add a glossy sheen. Always test first.
Can I seal just part of my quartz counters?
It’s best to seal the entire surface at the same time for an even appearance. However, you can just seal a damaged section if needed.
Should I seal quartz before or after installation?
Sealing can be done at either stage. Many fabricators will seal before installation. Resealing afterward is still recommended over time.
Can I use wax or polish on quartz instead of sealer?
Waxes and polishes are designed for different purposes than sealer. For optimal stain protection, a penetrating sealer formulated for quartz is best.
Conclusion
Resealing is a simple and affordable way to keep quartz countertops looking like new for years. While quartz itself is nonporous and resistant to stains, sealers provide an added layer of protection against scratches, etching and absorption of oils. For best results, use a specialized quartz sealer and follow the manufacturer’s application instructions carefully. With proper care and maintenance, beautiful quartz countertops can stay looking fantastic for the lifetime of the kitchen.
