FAQs

When do you use Fumed Pre-Treatment Stain rather than Pre-Aging?
Fumed is a tannin-reactive product that interacts with the natural tannin content in wood to create an authentically aged, gray appearance. Its effect is entirely dependent on the natural tannic levels in the wood, so even boards from the same tree can display varying tones, resulting in a unique, but potentially non-uniform finish. This distinctive, natural variation is why you might choose Fumed over Pre-Aging; Fumed delivers a more genuine, character-rich aged look that closely mimics the way wood naturally weathers over time.
