What NANOBEST GA is for
NANOBEST GA is positioned for building exterior walls. Its combination of photocatalytic action and superhydrophilicity is intended to help water spread across the treated surface, supporting rain-assisted removal of surface contamination.
Conditions to confirm
An exterior project must be reviewed around the actual substrate, existing finish, contamination, exposure and access conditions. A product description does not replace an on-site assessment.
- Exterior-wall material and existing finish
- Age and condition of the surface
- Previous coatings, sealers or cleaning chemicals
- Rain exposure, orientation and surrounding environment
- Application access and curing conditions
A responsible validation route
Before a full-scale installation, confirm compatibility and appearance on a limited area. Record preparation, application, weather and observation conditions so that the result can be evaluated against the intended anti-soiling objective.
Claims and project review
Performance varies with substrate, contamination, weather, preparation and application. Project-facing claims should be matched to relevant technical information and local requirements before use.
