Document Existing Treatments on New Shower Glass
Gather glass-supplier information before assuming new glazing is untreated.
Updated · NANOLAB Knowledge
New shower glass may already have a treatment applied by its supplier or during installation. Before adding another coating, establish what is known about the surface. The absence of visible residue is not proof that the glass is untreated.
Request the supplier record
Ask for the glazing identification, available product information and details of any factory-applied surface treatment. Include the installation record where relevant. Preserve the exact wording supplied rather than translating a broad marketing term into a technical conclusion about compatibility.
Record uncertainty clearly
If the supplier cannot identify the treatment, state that limitation in the project file. Photographs may help identify the enclosure but cannot necessarily establish its surface chemistry. For example, water behaviour alone should not be used to name an unknown factory treatment.
Obtain an application-specific recommendation
Provide the coating manufacturer with the glass information, intended use and existing-treatment details. Follow the approved assessment or trial route rather than assuming that another protective layer can be added. Keep the answer linked to the original supplier information. This creates a traceable basis for the decision and helps future maintenance staff understand the installed system. The purpose is to confirm the surface before treatment, not to treat every new enclosure as a blank substrate because it has not yet been used by the customer.
Keep the factory-treatment enquiry traceable
Request the glass or enclosure product identifier, supplier, order reference and any available treatment documentation. Record whether the information describes the glass itself, an aftermarket application or merely a general product range. Keep the supplier's exact answer with the project.
If the treatment remains unknown, state that clearly to the coating manufacturer and ask for a supported assessment route. Do not use a water test to assign a brand or chemistry. A new enclosure can look clean while still having a surface treatment that matters to the next process. The record should explain how the existing surface was identified, or why the project remains conditional until it can be assessed.
