Quartz countertops are an extremely popular choice for kitchen and bathroom remodeling projects due to their durability, low maintenance, and stylish appearance. Though quartz is very resilient, proper sealing is still recommended to protect its beauty and extend its lifespan. Here is a detailed overview on sealing quartz countertops.
What is Quartz?
Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. This combination creates an incredibly hard, non-porous surface that resists scratches, stains, heat, and water.
While pure natural stone requires regular sealing, quartz only needs occasional sealing due to its low porosity. Still, sealing is recommended to enhance stain resistance and simplify cleaning.
Should You Seal Quartz Countertops?
Sealing quartz countertops is highly recommended for maximum stain protection and easiest maintenance. Though quartz itself is non-porous, the resin used in manufacturing is slightly porous. Sealing creates an added barrier preventing stains from absorbing into the resin binder.
Sealing is especially important for quartz counters in the kitchen where oil, wine, coffee, and other stubborn stains are common. Though quartz resists staining better than marble or granite, it isn’t completely stain-proof without sealing.
How Often Should You Seal Quartz?
Most manufacturers recommend sealing quartz every 1-2 years. Frequent use and exposure to stains may necessitate more frequent sealing, while low-use surfaces may go longer without needing reapplication.
New quartz counters should be sealed immediately after installation. After the initial sealing, examine the counters yearly to determine if sealing is required. Renew the seal whenever liquids begin to darken or soak into the surface rather than bead up.
What is the Best Quartz Countertop Sealer?
Look for a high-quality impregnating sealer designed for natural stone when choosing a quartz sealer. Impregnating sealers soak into the surface pores and create an invisible barrier to repel stains.
Top choices include Miracle Sealants 511 Impregnator, DryTreat Stain-Proof, or Granite Gold Sealer. Be sure to avoid flimsy water-based acrylic sealers. Though impregnating sealers typically cost more, their durability and performance are far superior.
How to Seal Quartz Countertops
Sealing quartz counters is a quick and simple process when done properly:
- Impregnating sealer
- Microfiber cloths
- Painter’s tape
- Disposable gloves
- Clean counters thoroughly with a gentle stone cleaner to remove any dirt or residue. Rinse and allow to dry completely.
- Tape off any adjacent surfaces like walls, backsplashes, appliances etc. to prevent sealing product from contacting them.
- Apply sealer according to manufacturer directions, using a clean microfiber cloth. Rub small sections vigorously to work sealer into the stone.
- Allow sealer to soak 3-5 minutes then thoroughly buff off any excess with dry microfiber towels.
- Avoid water contact with sealed counters for at least 24-48 hours while sealer fully cures.
- Remove painters tape and enjoy your freshly sealed countertops!
FAQs About Sealing Quartz
Should I seal quartz counters before or after installation?
It’s best to seal after installation. This allows you to keep the counters pristine until construction is complete. Seal immediately once counters are installed.
How can I tell if my quartz counters need resealing?
Signs quartz needs resealing include stains resting on the surface rather than wiping away easily and liquids soaking in rather than beading up. Annual inspections help spot the need for renewal.
Is sealing quartz counters necessary?
Sealing isn’t required but is highly recommended by manufacturers and countertop professionals. The minimal time and cost of sealing is well worth it for the added protection and easier cleaning it provides.
Can I use a granite sealer on quartz?
Yes, an impregnating stone sealer formulated for use on granite, marble, and other natural stone surfaces will work excellently on quartz too. Avoid flimsy water-based acrylic sealers.
How long does quartz sealer last?
Expect a high-quality impregnating sealer to last 1-2 years on a quartz countertop with average use. More frequent staining or use may require more frequent reapplication.
Regular sealing is an easy and affordable way to help your beautiful quartz counters maintain their good looks. Taking a few minutes for sealing can prevent stubborn stains and keep your counters looking like new for decades. Be sure to use a reputable impregnating sealer and properly prepare the surface for best results. With proper care, quartz makes an unbeatable countertop choice.
