Rubio® Monocoat Fumed is a tannin-reactive pretreatment that creates an authentic aged grey effect on high-tannin woods, especially oak. This user-friendly liquid works without toxic fumes, reacting with natural tannins to produce a unique grain contrast. Must be sealed afterwards with a Rubio oil to lock in both the look and durability.
Features: What’s Included: 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.
