Homeowners should evaluate each room individually rather than relying on a one-size-fits-all resealing schedule to ensure appropriate maintenance.

What Impact Do Cleaning Products Have on Surface Wear?

Utilising harsh or acidic cleaners can accelerate the degradation of sealers, particularly within grout lines. Even products considered safe for tiles can strip protective layers if misused or over-applied. A gentle, pH-neutral cleaner is advisable to preserve the seal and prolong the intervals between resealing, ensuring the longevity of your flooring.

How Do Indoor Climate and Airflow Affect Sealer Longevity?

Humidity levels and air circulation significantly influence how quickly grout and tile surfaces dry after cleaning. Inadequate ventilation can prolong moisture exposure, potentially compromising sealers over time. Homes with effective ventilation and balanced humidity levels tend to retain sealed surfaces intact for longer durations, particularly in bathrooms and utility areas, enhancing the overall durability of your flooring.
