Is it wise to use sealer or finish on restroom floors?


Answer #1:
Sealing of cement based grout lines (not glazed tiles) with a penetrating or impregnating sealer is recommended to prevent the penetration of urine, moisture and soil into the porous material and subsequent bacterial growth, odor and discoloration. This assumes a good, non-slip ceramic tile is in place, as is most appropriate for rest rooms and ease of cleaning.
If you are faced with resilient tile rest room floors, as most of us are, you will find it advantageous to seal and coat the tiles with a quality finish. This will make the floors more attractive and easier to maintain. However, the drawbacks of time, cost, and mess are unavoidable and to change that, talk with the architect.

Answer #2:
In almost all cases, you should not use topical seal or synthetic floor coatings in restrooms. They create potential breeding harbors for pathogens, they can assist odor growth, and they provide a smooth coat over the anti-slip properties of most floor surfaces used in restrooms.
This is to say nothing of the needless additional expense of stripping, coating and handling complaints, plus the additional slip and fall risk during the stripping/recoating process.
