Why one number is not appropriate for every surface
Protective-coating durability is strongly affected by the substrate and how the surface is used. A shower glass panel, solar module, kitchen stone surface and stainless-steel handrail experience very different cleaning, abrasion and environmental conditions.
What affects durability
Preparation
Contamination, residues and poor surface preparation can affect adhesion and performance.
Exposure
UV, weather, heat, water chemistry and outdoor contamination vary by application.
Cleaning
Abrasive tools and aggressive chemistry may shorten coating life.
Frequently Asked Questions
How long does CleanShield last?
A single universal service-life claim should not be assumed. Coating life depends on surface type, abrasion, cleaning chemistry, exposure, preparation, application quality and maintenance.
What can shorten coating life?
Aggressive cleaners, abrasive pads, heavy mechanical wear, outdoor exposure, poor preparation and incompatible substrates may reduce service life.
How do I know when reapplication is needed?
Reapplication decisions should be based on observed surface behaviour and maintenance performance rather than a fixed calendar interval unless project-specific guidance has been established.
