Natural Sealer

The Tile Doctor Natural Sealer is a solvent based, no-sheen impregnating sealer formulated for protection of the natural character and appearance of unsealed surfaces and natural stone. It contains built in stain protection and durability perfect for professional installations. The layer of protection forms a vapor permeable barrier that resists water, grease, oil, and dirt.

The formula is non-yellowing and is weather resistant. May also be used as a pre-grout sealer and for sealing grout joints.

COVERAGE: 400-1500 square feet per gallon per coat. Coverage will vary depending on type of stone, porosity and texture of surface absorption, temperature, humidity and method of application.

Read entire label before using. Surface must be clean, dry and free of existing sealers or coatings. Allow at least 48 hours after new installations before sealing. Apply and saturate surfaces using a paint brush, paint roller, paint pad/applicator, clean towel or low pressure sprayer with no more than 25 psi. Note: Do NOT Aerosolize. Be sure that any sealer that does not penetrate surface is polished off surface within 5 minutes of application using absorbent paper or cotton towels. If 2 or more coats are applied, allow a minimum of 2 hours drying time between coats. Achieves full cure in 48 hours. Some highly porous surfaces may require an additional coat after full cure. Clean applicator tools with mineral spirits after each use.

GROUT RELEASE APPLICATION: For new installations, follow application procedure above. Allow to cure a minimum of 2 hours before applying grout.

TEST A SMALL AREA according to application instructions with a 24-hour cure time to determine desired results. Test for stain repellency using likely contaminants.
