Buying Guide
- Application method: Choose a formula that matches your preferred method (brush, spray, or bottle). Spray formulas reduce bending and kneeling but may require masking adjacent tiles.
- Indoor vs. outdoor use: For exterior installations, prioritize weather resistance and UV stability; interior options may emphasize low odor and low VOCs.
- Appearance: If you want grout to maintain a natural look, select a clear or tinted sealer. Colorant options are ideal for reconciling faded grout with tile color.
- Durability and coverage: Consider coverage per bottle and longevity. Pro-grade products often offer longer-lasting protection but may require more careful handling.
- Safety and environmental impact: Look for zero VOC, non-toxic, and low-odor formulations if you have sensitive occupants or a small, ventilated space.
- Maintenance compatibility: Some sealers allow easy cleaning after curing, while others offer enhanced stain resistance for high-traffic areas like bathrooms and kitchens.
- Professional vs. DIY: If you’re sealing large areas or stone tiles, a spray format or large-capacity bottle may save time and labor costs.
