TileLab® Grout Sealer (Aerosol)

TileLab® Grout Sealer is a ready-to-use, water-based, penetrating sealer that resists most common oil and water-based stains. With a 360 nozzle, it is a quick and easy way to apply a sealer to sanded or non-sanded grout while in a standing position. The steady stream from the nozzle and the foaming action of the sealer makes it easy to aim and seal. Grout Sealer makes cleaning easier.


Protects sanded and non-sanded grout joints from grease, coffee, wine, cooking oil, bath oils, colored juices, ketchup, mustard and every-day dust and dirt to keep grout bright and new.

Pre-Grout Sealer/Grout Release

Porous tile, such as clay and Saltillo pavers, can be stained by grout during installation. Sealing the tile before grouting will make grout removal much easier. Apply two coats of sealer according to directions after tile has been bonded for a minimum of 24 hours, or apply to front face of tile before installation.
