Change cleaning and chemicals
First question, not a consolation prize.
Some floors fail a wet-pendulum test because polish, sealer residue or the wrong detergent has filled the texture that used to provide grip. Tile, vinyl and sealed concrete all suffer this. If the covering still has a face that can work, the opinion may stop at a written cleaning method and a change of chemistry — and a warning that the next contractor must not put the old product back on.
That path only holds if the report and the surface agree. We will not hide a worn, polished-out floor behind a new mopping schedule.
Anti-slip treatment on the existing floor
When the covering can stay and still be made safer when wet.
Treatment means working the existing face — etching, coating, or a system chosen for that substrate — so wet grip moves toward the required P-rating. Kitchens, bathrooms, entries and pool surrounds are common, and they are not interchangeable. A treatment that belongs on porcelain is a poor idea on a worn vinyl sheet. We name the approach after we have read the report, not before.
There is no single coating that is appropriate for every hospital corridor and every school wet area. If a system cannot be specified against the material in front of us, we will say so and move to grind or replace.
Grind and profile
When the face has to be opened, or when profiling is the finish.
Sealed or over-polished concrete, some terrazzo, and coatings that will not accept a treatment often need mechanical preparation. Grinding can be the whole remedy — a new profile that the pendulum can read — or it can be the step before a treatment is applied. The opinion states which, because the two jobs are priced and scheduled differently.
Grind is dusty, noisy and needs isolation. We would rather say that in the quote than discover it on the morning of the works.
Replace the covering
When keeping the floor would be theatre.
Some finishes cannot be brought to the required rating without destroying them. A smooth, worn vinyl in a commercial kitchen, or a glazed tile that has no texture left to treat, is often cheaper and more honest to replace. Replacement is specified to the use of the space and the P-rating that location needs — not to a leftover roll in a warehouse.
If a lighter path will do, we will not talk you into a new floor.
