Question: 1 / 400

What is a primary risk associated with not using a sealant on porous tile?

Decreased bonding surface

Increased risk of cracking

Increased risk of staining and water damage

Not using a sealant on porous tile significantly heightens the risk of staining and water damage. Porous tiles have tiny openings that can absorb moisture, dirt, and other substances. When a sealant is not applied, these materials can seep into the tile, leading to permanent stains and bacterial growth, which can degrade both the appearance and integrity of the tile over time.

Moreover, the absorption of water can weaken the bond between the tile and the substrate, possibly leading to issues like mold and mildew if the absorbed moisture isn't adequately managed. Unsightly spots can develop, and water damage over time can compromise the subfloor or wall structure beneath the tile. Overall, applying a sealant is a critical preventive measure to maintain the durability and aesthetic quality of porous tiles.
