Buying Guide: Key Considerations For Granite Sealing
What does a granite sealer do?
A granite sealer penetrates the stone’s surface to form a protective barrier that reduces porosity. This helps resist stains from oils, wines, and acids, while maintaining the stone’s natural color and texture. Choose water-based, non-toxic formulas for interior surfaces in kitchens and baths.
How to choose the right sealer
- Stone compatibility: Confirm it’s safe for granite and other stone types you own.
- Food-contact safety: If countertops are used for food prep, pick a sealer labeled as food-safe or kitchen-safe.
- Ease of use: Spray-and-wipe formulas are convenient for large surfaces; deeper penetrate formulas may offer longer protection.
- Durability: Consider the expected reapplication interval based on usage and cleaning frequency.
Application tips
- Test in an inconspicuous area before full application.
- Ensure surfaces are dry and clean prior to sealing.
- Apply evenly with a sprayer or cloth; wipe away excess promptly.
Maintenance and care after sealing
Regular cleaning with a non-abrasive cleaner helps maintain the sealer’s effectiveness. Avoid harsh chemicals that can degrade the protective layer. Periodically re-seal high-traffic areas to sustain stain resistance.
