Why You Don’t Need to Seal Quartz
Non-porous quartz surface
High-quality quartz is non-porous—unlike natural stone. Coffee spills, makeup smudges, or cooking oil won’t seep in. Just wipe them quickly, and you’re done. No sealing rituals required.
Sealing could RUIN your investment
That gorgeous polished finish? A bad sealant might:
• Create uneven patches
• Trap stains under the coating
• Require costly removal if applied incorrectly
Your wallet will thank you
Sealants wear off in 1–2 years. Why pay for reapplication when your quartz naturally resists stains?
Food Safety
Your kitchen countertop touches food daily. Cheap sealants may leach chemicals—why risk it?
When You Might Need to Seal
Low-grade quartz
Does your surface:
• Stain easily?
• Feel “soft” when scratched with a knife?
• Show tiny pores?
If yes, sealing might help—but consider replacing it long-term.
Using quartz in a lab or workshop
Constant exposure to acids, solvents, or harsh chemicals? Use a chemical-resistant sealant like polyurethane.
Using quartz outdoors
UV rays and freezing winters can damage resin binders. If unavoidable, use outdoor-specific sealants and provide shade.
