Quartz countertops are an increasingly popular choice for kitchen and bathroom remodeling projects. Made from engineered stone, quartz combines the aesthetic appeal of natural stone with the consistent coloration, durability, and low maintenance of solid surfaces. However, there is often debate around whether quartz countertops need to be sealed. This article will provide a comprehensive overview of the key factors to consider when deciding if you need to seal a quartz countertop.
What is Quartz?
Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The exact composition varies by brand and product line, but a typical quartz slab contains:
- 90-94% ground quartz
- 6-10% polymer resins
- Pigments for color
The resins bind the quartz particles together to form a durable, non-porous material that maintains its color and glossy sheen without ongoing maintenance.
Compared to natural stone counters like granite and marble, quartz offers superior durability, scratch resistance, and stain resistance. The non-porous surface makes quartz less prone to harboring bacteria. Quartz countertops are available in a diverse array of colors and patterns to suit any design aesthetic.
Key Benefits of Quartz Countertops:
- Extremely durable and scratch resistant
- Non-porous so resists staining
- Consistent patterning and color throughout the slab
- Low maintenance compared to natural stone
- Mold and mildew resistant
- Heat resistant
- Available in a wide range of colors/patterns
Do You Need to Seal Quartz Countertops?
The short answer is no – quartz countertops do not require sealing in most cases.
The resins used in manufacturing quartz make it non-porous, so it does not readily absorb liquids and stains like natural stone. Without pores to penetrate, sealers cannot bond effectively to a quartz surface. Most quartz manufacturers agree that sealing is typically unnecessary.
However, there are a few exceptions where sealing quartz may provide some benefit:
At Installation
Sealing a new quartz countertop right after installation can help prevent staining from construction debris, paint, glue, and other contaminants. Allow any adhesives or grout used in the installation to cure fully, then clean the counters thoroughly before applying a stone sealer.
If Exposed to Intense Heat
Quartz is resistant to heat damage up to about 300°F. Exposure to extreme heat from pots/pans or hot appliances over time may compromise the surface. Sealing provides an added layer of protection against damage from prolonged hot pan or appliance contact.
For Extra Stain Protection
While quartz itself is non-porous, micro-gaps can occasionally exist where separate slabs are joined at seams. Sealing creates a barrier helping prevent stains from penetrating into these crevices. It can also minimize the chance of damage from acidic substances like lemon juice or vinegar that may lightly etch quartz over time with repeated exposure.
Around Sinks/Faucets
Areas surrounding sinks and faucets tend to get wet more often, making them more prone to damage. The extra humidity can potentially react with minerals in tap water leading to etching. Sealing these zones adds a layer of protection.
For Peace of Mind
Given the minimal risks with sealing quartz, some homeowners opt to apply sealer simply for added peace of mind. Since reapplication is only needed every 1-2 years, it represents a minor maintenance task.
How to Seal a Quartz Countertop
Sealing quartz counters is a relatively simple process, but it’s important to use the right type of sealer and apply it correctly to get lasting results.
Clean Thoroughly
Before sealing, the quartz must be completely clean. Wash counters with a pH neutral cleaner, then rinse thoroughly. Allow to dry fully. Check for any remaining debris stuck in crevices.
Choose a Sealer
Select a sealer formulated for natural stone that contains silicone, like Dry Treat 40SK. Silicone-based sealers work well on quartz because they resist build up from repeated applications.
Avoid flammable solvent-based sealers, as they can damage quartz resin and cause yellowing. Steer clear of topical acrylic sealers, as they tend to peel and flake over time.
Apply Sealer Properly
Carefully read and follow the product directions for full curing times and layers needed. Most require 2-3 thin coats applied 10 minutes apart. Use a clean sponge or soft cloth to apply sealer sparingly in small sections. Spread evenly, then thoroughly wipe away all excess. Allow curing fully between coats and avoid use for at least 24 hours. Applying too much sealer or insufficient drying can lead to a hazy finish.
Cure Completely Before Use
It’s critical to allow the sealer to cure fully before use. This ensures food or liquids don’t become tainted and prevents damage to the seal. Adhering to the product directions, this is typically 24-72 hours after the final coat. Avoid abrasive cleaners during this period as well.
Reapply as Needed
Quartz sealer should last 1-2 years with proper application. Reapply if you notice stains starting to absorb rather than beading up and wiping away easily. Test a small inconspicuous area first before recoating the entire surface.
Does Sealing Quartz Change the Appearance?
When applied correctly, quartz sealer provides an invisible layer of protection that does not alter the appearance of the countertop. Sealers bond below the surface, so the color, glossiness, texture and finish remain unchanged. Interior designers often apply sealer to quartz installations for added protection without impacting the aesthetic.
To maintain the original appearance:
- Select a clear non-pigmented sealer formulated for stone.
- Apply thin coats, wiping away any excess.
- Allow sealer to cure fully before use.
- Test on a small area first to confirm results.
- Avoid bottom-dollar DIY sealers that may discolor.
Quartz already has excellent stain resistance without sealer. But properly sealed counters gain an imperceptible extra level of protection from stains and etches – and peace of mind for homeowners.
Maintenance Tips for Sealed Quartz
Once quartz is sealed, maintaining both the sealer and the underlying surface properly ensures the best and longest-lasting results.
Use Cutting Boards
Cutting directly on the counter can wear away the sealer over time. Use a cutting board for food prep instead.
Wipe Up Spills Promptly
One benefit of sealing is liquid beads up rather than absorbing immediately. But be sure to wipe up spills as soon as possible to prevent possible damage if left too long.
Avoid Harsh Chemicals
Clean quartz regularly using a pH balanced cleaner. Avoid abrasive scouring pads or powders, alkaline cleaners, and acidic products (like vinegar) that can degrade sealer molecules and etch the surface.
Don’t Use Wax or Polishes
Wax can interact with sealer and create cloudiness. Other polishes also provide limited benefits on quartz, so are best avoided.
Reseal on Schedule
Plan to reapply sealer about every 1-2 years, or whenever liquids start absorbing rather than beading up on the surface. This ensures you maintain the protective barrier.
Address Any Damage Promptly
If areas do get scratched or etched over time, have a professional promptly repair and reseal. This prevents damage from worsening or spreading. Even a properly sealed counter still requires care and attention.
FAQs About Sealing Quartz Countertops
Is sealing absolutely necessary for quartz counters?
Sealing is not an absolute necessity for quartz since the material is non-porous. But it can provide extra protection in certain situations like around sinks or seams. Periodic sealing is an inexpensive way to help keep quartz counters pristine long-term.
What types of sealers work on quartz?
Silicone-based penetrating sealers formulated for natural stone work best. Avoid flammable solvent sealers. Acrylic sealers tend to peel and do not last.
How can I tell if my quartz counters are sealed?
Run a few water droplets on the surface. If they bead up and can be wiped away easily, a sealer is likely present. If the water absorbs and darkens the quartz, it is unsealed and more prone to staining.
How long does quartz sealer last?
Expect to get 1-2 years of protection from a silicone-based quartz sealer before reapplication is needed. Duration depends on wear and proper application. Reseal sooner if you notice liquids absorbing rather than beading up.
Should I seal quartz countertops before or after installation?
Sealing quartz prior to installation helps protect against construction debris and mishaps. But you’ll get the best bond if you wait until after counters are installed, grouted and thoroughly cleaned.
Can I seal just part of my quartz counters?
You can seal only select areas like around the sink if desired. But for optimal protection, it is best to seal the entire surface uniformly following the product directions.
How soon can I use my counters after sealing?
Curing times vary by sealer but expect to wait 24-72 hours after the final coat before resuming normal use of the counters. This ensures food is not contaminated and lets the sealer establish a strong bond.
Will sealing change the look of my quartz?
A clear non-pigmented quartz sealer should not alter the appearance if applied properly in thin uniform coats allowing full drying time. Always test on a scrap or hidden spot first.
Conclusion
While sealing is not strictly required for quartz countertops, it can provide an added level of protection against stains, etching, and heat damage over time. Sealing at installation and periodically maintaining the seal helps quartz counters stay looking like new for decades. With proper product selection and application, sealing should not change the appearance or originally intended finish. For homeowners wanting to keep their investment pristine as long as possible, taking the minimal step of sealing quartz counters is highly recommended.
