NUSKU FIREBLOCKER PAINT GRADE

As a paint grade product, the way Nusku Fireblocker weathers over time is largely based on the finishes & coatings that are applied following installation. We always recommend refinishing paint grade every few years for optimal performance, but can still experience minor grain raise and checking as an all natural wood product.

NUSKU FIREBLOCKER WEATHERING

The goal of the applied finishes on Nusku Fireblocker is to reduce the possibility of moisture exposure. When Redwood is exposed to excess moisture it can cause grain raise, tannin bleed & swelling. Thus, high level of moisture resistance in exterior finishes is crucial.

MOISTURE EXPOSURE

UV rays can be brutal on any paint grade finish, & thus UV inhibitors in the coating are important. Like most items left out in the sun, the material and vivid color in the paint will fade over time. We typically suggest lighter finish colors to reduce the appearance of fading. 

UV EXPOSURE
