Water-Based Stain Protection for Quartz & Engineered Stone
Lustro Italiano Quartz Stone Sealer is a water-based sealer purpose-built to protect quartz and engineered stone surfaces from stains, spills, and dirt. It penetrates the surface to create a protective barrier without altering the stone's color or leaving any surface film — the quartz looks exactly the same after sealing, just better protected.
Food-safe formula. Ready-to-use 16 oz spray — no dilution required. Compatible with all major quartz brands and engineered stone products.

Frequently Asked Questions
Does quartz need to be sealed?
Engineered quartz is non-porous and more stain-resistant than natural stone, but sealing adds an additional layer of protection against surface staining and makes routine cleaning easier. It's particularly useful in high-use kitchen environments.
Will it change the color or appearance of my quartz?
No. The water-based formula is designed to leave no color change and no surface film — the quartz looks the same after sealing.
Is it food-safe after curing?
Yes — food-safe after the 24-hour cure period.
How often do I need to reapply?
Reapply as needed based on use and surface conditions. High-traffic kitchen countertops may benefit from resealing annually.
Can I use it on natural stone like granite or marble?
This sealer is formulated for quartz and engineered stone. For natural stone, use Lustro Italiano Stone Sealer instead.
How long before I can use the surface after sealing?
Wait 24 hours before use, especially on floors.
