Quartz countertops like Kova Blanco are an increasingly popular option for kitchen and bathroom remodels thanks to their durability, aesthetics, and low maintenance. However, some homeowners wonder if they need to take additional steps to protect and seal their quartz countertops. Here is a detailed look at whether Kova Blanco quartz countertops need to be sealed.
What is Kova Blanco Quartz?
Kova Blanco is a popular brand and color of engineered quartz countertops. Like other quartz countertops, Kova Blanco is made from ground natural quartz combined with polymer resins and pigments. The resins bind the quartz particles together to form a durable, non-porous surface that mimics the look of natural stone.
Kova Blanco quartz has a crisp white background with faint grey veining that provides depth and dimension. The white base lends itself well to both traditional and contemporary kitchen designs. Kova Blanco resists stains, scratches, heat, and bacteria growth. It’s an ideal low maintenance option for busy kitchens.
Do Quartz Countertops Need To Be Sealed?
Unlike granite and marble, quartz countertops like Kova Blanco do not require regular sealing. The polymer resins make quartz non-porous, so liquids cannot penetrate the surface. Quartz repels stains rather than absorbing them the way natural stone does. This also makes quartz resistant to bacteria growth.
Sealing is only necessary for porous materials like granite, marble, and concrete that absorb liquids. The sealant fills pores in the material to prevent staining. Since quartz lacks pores, sealants only remain on the surface and do not bond properly. Most manufacturers advise against sealing quartz.
Benefits of Quartz Sealing
Though unnecessary, some homeowners still wish to seal their quartz counters for added protection. Potential benefits of quartz sealing include:
- Added moisture protection – Sealing may provide a hydrophobic barrier against liquids.
- Easier cleaning – Sealants can cause liquids to bead up rather than spread out, making quartz easier to wipe clean.
- Enhanced shine – Sealants temporarily improve the glossiness of the countertop surface.
However, these benefits are short-lived as sealants eventually wear off the non-porous quartz surface with regular use and cleaning.
Risks of Sealing Quartz
Sealing quartz countertops comes with some potential drawbacks:
- Sealants wear off quickly – Quartz lacks pores for sealants to bond to permanently. Most sealants only last weeks or months.
- Can affect appearance – Sealants may give quartz an unnatural, plasticky look. Color and gloss level may also appear different.
- Void warranty – Many quartz warranties prohibit sealing, as this indicates the material is porous (which quartz is not).
- Not cost-effective – Regular reapplication is required, making sealing quartz an unwise investment.
For these reasons, manufacturers strongly advise against sealing quartz counters. The risks outweigh the very limited benefits.
Caring for Kova Blanco Quartz
The good news is that Kova Blanco quartz requires minimal maintenance without sealing. To keep your Kova Blanco quartz pristine:
- Clean frequently with mild soap and water.
- Blot spills quickly to prevent staining.
- Avoid abrasive cleaners or pads.
- Use a stone cleaner for periodic deep cleaning.
- Don’t expose to strong chemicals.
- Reseal if necessary around sinks or cooktops.
With routine care, Kova Blanco quartz will retain its beauty and perform like new for many years without sealing required. Invest in high quality quartz like Kova Blanco, and avoid unnecessary steps that provide minimal benefit.
Frequently Asked Questions
Should I seal my Kova Blanco quartz countertops right after installation?
No, sealing is not necessary or recommended for new Kova Blanco quartz countertops. The polymer resins make quartz non-porous, so sealing will not provide any real benefits. Avoid sealing so as not to potentially void the manufacturer’s warranty.
How can I add shine to my Kova Blanco quartz?
Regular cleaning with a stone cleaner will help maintain the natural shine of Kova Blanco quartz. Avoid waxes or sealants, which may temporarily add gloss but can leave residue. For added shine, consider polishing your quartz countertop once or twice per year.
What’s the best way to disinfect my quartz countertops?
To safely kill germs on your Kova Blanco quartz, use a disinfectant designed for stone surfaces. Many quartz manufacturers recommend an antimicrobial disinfectant. Avoid bleach or harsh chemicals. Thoroughly rinse after disinfecting.
Will sealing prevent etching on my quartz counters?
No, sealants cannot prevent etching on quartz counters. To avoid etching, always use a cutting board and avoid exposing your Kova Blanco surface to acidic foods like citrus and tomatoes. Sealants wear away too quickly to guard against etching.
Should I seal the seam between my Kova Blanco quartz counters and sink?
You may wish to use a clear silicone caulk to seal the seam near sinks or cooktops to prevent moisture penetration. However, sealing the entire quartz counter is unnecessary. Apply caulk carefully to avoid staining the quartz surface.
Kova Blanco’s durable, non-porous quartz material does not require sealing like natural stone counters do. Manufacturers strongly recommend against sealing, as quartz lacks pores for sealants to bond to permanently. At best, sealing briefly enhances shine and moisture resistance before wearing off. At worst, sealing quartz can damage the finish, void warranties, and create a need for frequent reapplication. With simple care, Kova Blanco quartz will maintain its pristine beauty and water-resistant properties for years without sealing required. Invest in quality quartz that stands up to everyday life without unnecessary maintenance.
