Wood Sealant

Stop Sanding. Stop Staining. Stop the Cycle.

Every two years you sand it down, apply a fresh stain, and watch Wisconsin weather undo all of it by spring. NanoShield’s GoNano wood sealant permanently bonds to wood fibers at the molecular level — stopping rot, repelling moisture, and ending the maintenance treadmill for good.
The Traditional Staining Cycle vs. GoNano
Year 1 — Fresh stain applied
Fresh stain applied. Looks great. You spent the weekend on your knees sanding and applying two coats.
Cost: $400–$800 + your weekend
Year 2 — Fading & peeling begins

UV and moisture break down the surface stain. Gray streaks return. Peeling edges appear.

Cost: Starting over again
Year 5+ — Rot sets in

Repeated moisture exposure causes structural rot. Full deck replacement looms.

Cost: Major replacement expense

GoNano — One treatment, lasting protection

Molecular bond repels moisture, stops UV graying, prevents rot. No annual maintenance.

Result: 15+ years of protection

THE REAL PROBLEM

Say Goodbye to The Never ending Deck Staining Cycle

The deck stain industry depends on you coming back every two years. It’s a cycle designed to repeat, not a solution designed to last.

The other thing no one tells you: the sanding required before each restain removes a thin layer of wood every time. After 5–6 cycles, you’ve sanded away the best part of your deck boards — and you’re looking at replacement regardless.

Moisture & Water Infiltration

Water is wood's primary enemy. Once it penetrates past the surface, no amount of staining prevents the slow structural breakdown that follows.

UV Graying & Fiber Breakdown

Wisconsin summers are harder on wood than most homeowners realize. UV radiation breaks down lignin — the natural glue that holds wood fibers together — turning rich wood gray and brittle.

Mold, Mildew & Rot

Persistent moisture creates the perfect environment for mold and the rot fungi that structurally compromise wood from the inside. Once rot starts, it spreads — and deck replacement follows.

Fox Valley Freeze-Thaw Cycling

Water trapped in wood fibers freezes and expands every Wisconsin winter — splitting fibers, creating cracks, and accelerating every other form of wood degradation.

THE GONANO DIFFERENCE

Not a stain. Not just a wood sealant. A permanent Molecular Bond.

GoNano doesn’t coat the surface of your wood — it bonds chemically with the wood fibers themselves, from the inside out. Here’s exactly what that means for your deck.

How GoNano Wood Sealant Works
Deep Fiber Penetration

GoNano nano-particles are small enough to travel deep into the wood’s cellular structure — far beyond what any surface stain or sealer reaches.

Hydrophobic Bonding

Inside the wood fibers, GoNano forms a permanent hydrophobic (water-repelling) bond. Water hitting the surface beads up and rolls off — it never enters the wood.

UV Stabilization

GoNano wood sealant stabilizes the lignin in the wood fiber — slowing the UV degradation that causes graying and brittleness, preserving the wood’s natural color and structural integrity.

Mold & Rot Prevention

With moisture blocked at the fiber level, the conditions for mold, mildew, and rot fungi are eliminated. No moisture means no rot — it’s that direct.

Permanent Protection

The molecular bond doesn’t wash away, peel, or fade. This is a one-time treatment — not the beginning of a new maintenance cycle.

APPLICATIONS

Sealing Every Wood Surface Exposed to Wisconsin Weather

GoNano wood sealant works on virtually any exterior wood surface in the Fox Valley — wherever moisture, UV, freeze-thaw cycles or all the above are doing damage.

Decks & Patios

Your deck takes more weather punishment than any other wood surface. GoNano permanently ends the sand-stain-repeat cycle most Fox Valley homeowners are trapped in.

  • Permanent moisture barrier
  • Stops rot & fiber breakdown
  • Ends the staining cycle for good

Fences & Siding

Wood fences and siding are constantly exposed but rarely maintained well enough. GoNano provides permanent protection without changing the look of your property.

  • Stops moisture infiltration
  • Prevents post rot at ground contact
  • Preserves natural wood appearance
  • Residential & commercial

Outbuildings & Structures

Garages, sheds, barns, and pergolas — any wood structure exposed to Fox Valley weather is a candidate for GoNano permanent protection.

  • Structural wood protection
  • Works on rough-sawn & finished wood
  • Ideal for older structures
  • Commercial & agricultural use
I just restained my deck last summer and it's already looking gray again. Why won't anything last?

Because surface stains are fighting a battle they’re not designed to win in Wisconsin. The Fox Valley’s UV intensity bleaches the stain from the top, while moisture infiltration and freeze-thaw cycling break it down from beneath. Most deck stains are formulated for climates with milder winters — and even the best ones are designed to last two years, not indefinitely.

GoNano wood sealant approaches the problem differently. Instead of covering the surface, it bonds permanently to the wood fibers at a cellular level, stabilizing the lignin that UV breaks down and creating a hydrophobic barrier that water can’t penetrate. The result isn’t a stain that will fade — it’s a molecular change to the wood itself. No maintenance cycle. No annual restaining.

GoNano wood treatment works best as a protective measure — applied before or in the early stages of rot, it permanently blocks the moisture that causes rot to spread. For decks with minor surface deterioration or isolated soft spots, treatment can halt further damage and significantly extend the deck’s life.

Active, advancing structural rot is a different situation. If the rot has compromised the structural integrity of joists, posts, or boards throughout, those members need to be replaced first — GoNano can then protect the new and remaining wood permanently. Derek will assess the condition of your wood during the free evaluation and give you an honest picture of what treatment can accomplish versus what needs to be addressed structurally first.

This is something we will assess during your free evaluation. GoNano needs to be able to penetrate into the wood fibers to form its molecular bond — if there’s a heavy film-forming stain or sealer on the surface, that layer may need to be stripped or lightly sanded first to allow full penetration. For decks with a thin, weathered, or largely-failed existing stain, treatment may be possible with minimal prep.

The prep requirement is one reason it’s worth getting the evaluation before assuming treatment isn’t an option for your specific deck.

Yes to both. GoNano wood sealant is effective on pressure-treated lumber, cedar, pine, hardwoods, and most common deck board species. Older wood in structurally sound condition is often an excellent candidate — the treatment restores the hydrophobic properties and UV resistance that new wood has naturally, essentially giving aging boards a new lease on life.

The age and species of your wood isn’t the determining factor for eligibility — the structural condition is. Solid boards with surface weathering respond very well to treatment. Boards that are structurally compromised by rot or splitting need to be replaced, then the new wood protected.
