Case study: Commercial Kitchen

Problem: Mildewed Tiles, mildewed grout in an active commercial kitchen

Solution: application of our permanent coating process

This was a County kitchen facility that always created a lot of steam. The steam and dampness caused the ceramic tile grout on the walls to breed mold and mildew. In addition, the ceramic tiles on the walls were difficult to keep clean from the grease. Conventional cleaning (bleach) was only temporary and became costly. They wanted a sealer that might help with both situations.

First, let’s establish that a conventional sealer would NOT be the answer. Any sealer would not only have a difficult time with adhesion, but that adhesion would be worn down by abrasion from the cleaning brushes and cleaning chemicals. We might also mention that using a sealer to protect the grout is literally a waste of time and money. Sealing grout does nothing to keep grout clean. The sealer penetrates the very porous grout, leaving the surface exposed. The grout must be coated, not sealed.

For numerous reasons, the solution was our coating process. First, this is a permanent coating rather than a temporary sealer. Secondly, our coating process is very durable and offers an inorganic solution. The coating process will not support mold & mildew growth. Third, by virtue of the coating curing on the surface of the tiles and grout, the grout was ‘coated’ to prevent moisture from forming. Periodic cleaning would involve wiping the tiles rather than scrubbing.
