Do I need to use Exterior Wood Cleaner before applying DuroGrit to fresh lumber?Updated a month ago

No, cleaning with Exterior Wood Cleaner is not necessary before applying DuroGrit to fresh, unexposed lumber—a good sanding will be enough. However, if the wood has been exposed and weathered, Exterior Wood Cleaner must be used before applying DuroGrit. For coarse-textured or rough-sawn wood surfaces, thoroughly dry scrub the surface or use Exterior Wood Cleaner if weathered.
