Buying Guide: Key Purchase Considerations
What to consider when choosing a granite sealer:
- Porosity: More porous stones require deeper penetration sealers for optimal performance.
- Finish: Do you prefer a dry, matte look or a slight sheen? Some sealers leave a visible finish; others are invisible after curing.
- Indoor vs. outdoor use: Outdoor applications may need stronger resistance to weather and salts.
- Application method: Look for ready-to-use formulas with simple wipe-on or spray-and-wipe steps for easier maintenance.
- Coverage: Calculate square footage to ensure you buy enough product for the area.
- Odor and environmental impact: Low-odor, water-based formulas are generally better for indoor air quality.
