Why Seal Quartz Countertops?
Although quartz is an extremely durable material, sealing it provides some key benefits:
- Protects against stains and etching – Quartz is non-porous, but sealing provides an extra layer of protection from spills, oils, and acidic foods that could stain or etch the surface over time.
- Prevents damage fromscratches and wear – The sealant helps prevent minor scratches, scuffs and reduces signs of wear and tear.
- Keeps the countertop lookingnew – Sealing fills in micro-pores and provides a like-new glossy sheen. It enhances the color and richness of the finish.
- Makes cleaning easier – Sealed quartz resists sticking, etching and absorption, so countertops wipe clean with minimal effort.
When to Seal Quartz Countertops
New quartz countertops come pre-sealed from the factory, but this initial layer of protection wears off over time. Here are some tips on when to reapply a sealant:
- Every 1-2 years for routine maintenance.
- If water/liquid is not beading up on the surface.
- If stains and etching are becoming a problem.
- After deep cleaning or restorative procedures.
- When the glossy finish looks dull.
- When installing new quartz counters.
Sealing quartz regularly will maintain its flawless, glossy finish.
What You Need to Seal Quartz Countertops
Sealing quartz is a relatively simple DIY project. Here is what you will need:
- Quartz sealant – Select a high-quality stone/quartz sealant formulated for dense surfaces.
- Microfiber cloths – For applying sealant and buffing.
- Paintbrush – To seal hard to reach areas.
- Rubbing alcohol – To properly clean and prep the surface.
- Painter’s tape – To protect walls and surfaces.
- Bucket of water – For dilution and rinsing.
Optional:
- Plastic wrap – To catch excess drips when applying sealant.
- Gloves and eye protection – To keep hands and eyes safe from chemicals.
How to Seal Quartz Countertops
Follow these step-by-step instructions for foolproof quartz countertop sealing:
1. Clean the Surface
- Remove everything from counters and tape off walls/surfaces with painter’s tape.
- Mix a solution of rubbing alcohol and water in a bucket.
- Dip microfiber cloths in the solution and wipe the entire surface.
- Rinse with a clean, damp microfiber cloth and dry thoroughly.
Thorough cleaning removes residues that could interfere with sealant bonding.
2. Apply the Sealant
- Shake the sealant bottle well and apply a thin layer directly onto the quartz.
- Use overlapping circular motions and strokes to distribute evenly.
- Alternatively, pour sealant into a paint tray and apply with a paintbrush for more control.
- Cover the entire surface, including edges and seams.
Tip: Cover surrounding areas with plastic wrap to catch excess drips.
3. Allow Proper Curing Time
- Allow the sealant to penetrate and dry completely, following manufacturer guidelines.
- Most products need 20-30 minutes drying time.
- Poor curing can lead to hazy results. Be patient!
4. Buff and Remove Excess
- Once fully cured, use a clean microfiber cloth to gently buff in circular motions.
- Remove any excess sealant and polish to a streak-free finish.
- Flip cloths frequently to prevent residue buildup.
- Repeat buffing and remove all residues.
5. Clean Tools and Surface
- Dampen microfiber cloths and wipe down the counters to remove residues.
- Rinse out paint tray and brushes with soap and water if used.
- Properly dispose of plastic wrap, gloves, and painter’s tape.
And that’s it! Properly sealed quartz countertops will maintain their flawless factory finish for years of beauty and protection.
FAQs About Sealing Quartz Countertops
How long does a quartz sealant last?
With proper application, a quality quartz sealant will typically last 1-2 years with proper maintenance.
How can you tell if quartz needs resealing?
Signs that indicate quartz counters need resealing include water not beading on the surface, visible stains/etching, loss of glossy sheen, and an increase in scratches/damage.
Is there a difference between sealing natural stone and quartz?
Yes, quartz requires a specially formulated sealant designed for non-porous surfaces. Using a stone sealant on quartz is ineffective.
Can I use wax or polish on quartz instead of sealant?
No, waxes sit on the surface and can build up over time. Sealants chemically bond to quartz to provide superior stain protection.
Will sealing quartz change the look of the finish?
A quality quartz sealant may slightly darken or enhance the natural tones but will not alter the appearance significantly. Properly sealed quartz maintains its original beauty.
Conclusion
Regularly sealing quartz countertops is the key to preserving their pristine factory finish long-term. It only takes a few easy steps and inexpensive products to protect quartz surfaces from damage, wear, and stains.
Be sure to properly clean, apply sealant evenly, allow to fully cure, and buff well for optimal results. Reapply every 1-2 years for maintenance. With proper sealing, quartz countertops will stay looking like new for many years of beauty and durability.
