The sun is brutal here. How long does it last?

Manufacturer spec runs up to 15 years depending on surface and exposure. A south-facing wall in the Okanagan is the demanding end of that, so plan for the low end of the range and expect to reapply sooner than on a shaded surface.

Does it help with wildfire ash?

Indirectly. A smooth, water-repellent surface holds less deposit and rinses more easily. It does not replace a cleaning after a heavy fire season.

Nanoxeal surface protection in Kelowna

The Okanagan is semi-arid: little rain, very hot summers and some of the strongest sun exposure in the country. What destroys exterior surfaces here is UV and temperature swing, not moisture.
