Provide additional adhesion

The correct answer is: Protect grout from stains and moisture

The primary function of a tile grout sealer is to protect grout from stains and moisture. Grout, while designed to fill the spaces between tiles, is often porous and can absorb liquids, oils, and dirt over time. When a sealer is applied, it creates a protective barrier on the grout surface, preventing these substances from penetrating and causing discoloration or weakening the integrity of the grout. This not only helps maintain the appearance of the grout but also contributes to the longevity of both the grout and the tiled surface. Choosing a grout sealer is essential for maintaining a clean and visually appealing installation, especially in areas prone to spills or high moisture, such as kitchens and bathrooms. A good sealer can significantly reduce the effort needed for cleaning and maintaining the grout over the years, making it an important aspect of tile installation and care.
