The Protective film applied at factory must be removed from the surface of the panel immediately after installation to the façade. The surface of Leminex repels dust, however over the time it may be necessary to clean their surfaces with soapy water for better aesthetic over time.
LEMINEX HPL laminates does not need an extra care. Cleaning is necessary under certain circumstances. For cleaning, use clean warm water, clean clothes or rags and soap. Never use solvent or cleaners containing solvent. Do not scrape with hard objects. Severe Marks such as pencil traces can be dealt with quickly with isopropyl alcohol.
As hPL do not suffer from corrosion and oxidation, no further surface protection and no maintenance apart from cleaning is needed.
