Reduces water absorption and protects roofs in good condition from exterior exposure.
Learn moreNano-B: protecting wood from moisture, without changing its look.
Nano-B is our hydrophobic treatment designed for exterior wood — decks, siding, and structures exposed to the elements. It limits moisture penetration and buildup in the wood fibres, reducing the conditions that promote mold, moss and lichen growth, while also helping protect the wood from the effects of the sun, including fading and premature aging, without coating it in varnish or a visible film.

Exterior wood is especially sensitive to moisture: swelling, cracking, and premature degradation can occur when water regularly penetrates its fibres. Reducing that absorption helps preserve the wood longer, without altering its natural appearance.
Reduces water absorption in the wood fibres
The treatment penetrates the wood’s porous structure rather than simply coating it.
Helps limit swelling and cracking from moisture
Wood that’s less exposed to water is wood we help preserve longer.
Keeps the wood’s natural appearance
No varnish or visible film — the treatment doesn’t change the surface finish.
Nano-B is suited to decks, exterior siding, and wood structures exposed to weather and moisture.
