Fusion Lock™ — Etches Into the Pores Of the Old Surface And Chemically Welds To Integrate The Porcelain Glaze Into The Old, Not On Top Of It

Fusion Lock™ Immersion & Cross-Hatch Test (Evidence, not hype)

Soaked for days, boiled to ~180 °F, razor scored, tape-pulled, and even hit with a weed-eater. No lift with Fusion Lock™. Control tile (no silanes) peels easily. Huck the Lab says hi.

Tensile Strength: 67.85 MPa (≈9,840 psi) — Is that good?

Coating Type Typical Tensile Strength (MPa) Notes
Standard Epoxy (2-part) 30–50 Softer feel; moisture and yellowing risk over time.
Acrylic Urethane (iso-cured) 40–60 Glossy; flexible; humidity-sensitive long term.
Powder Coat (poly/epoxy hybrid) 55–70 Tough; requires ~350–400 °F oven cure.
Factory Porcelain Enamel 65–90 Glass-ceramic fused at 1400 °F+; very hard, can chip if struck.
Silane/Ceramic Hybrid Glaze (e.g., Fusion Lock™) 65–75+ Self-etch adhesion + silane bonding; porcelain-hard with impact forgiveness.
Your Tested Coating 67.85 MPa ✅ In the porcelain-class range — excellent real-world durability.
  • What it means: High resistance to cracking or pulling apart under stress.
  • Homeowner upside: Great long-term adhesion, Eliminate edge chips, stable gloss after cure.
  • Context: Numbers are typical ranges on test material; actual performance also depends on after care. Both Fusion Lock and Porcelain Glaze tested at 67.85 MPa showing excellent bonding and finish coat durability

Fusion Lock — Molecular Self-Etching Bonding System

Fusion Lock is my proprietary silane system that chemically welds the new polyester liquid porcelain finish into the original surface for long-term adhesion.

Typical Fusion Lock Application Process

  1. Surface Prep: Clean, decontaminate, and degloss to open surface pores allowing the etch to sink into the open pores.
  2. Initial Coat: Applied by rubbing Fusion Lock into the open pores by hand.
  3. Fusion Lock Application: Applied one more time by hand before the initial porcelain glaze coat.
  4. Next Coat: Will be applied between porcelain glaze coats using melt-down technology so each coat gently melts into the previous coat allowing maximum cross-linking.

This system pairs with no-isocyanate materials and a heated HVLP application for proper film build and a deep, glossy finish.

What is Fusion Lock™ ?

Fusion Lock™ is my proprietary blend of four high-quality silanes plus a self-etching adhesion promoter—formulated over five years specifically for bathtub refinishing. The components work in a synergistic way to outperform any single product on its own.

To prove it, I sprayed a 9"×9" tile, let it cure for 30 hours, then put it through abuse: five days of full water immersion in a 5-gallon bucket, weed-eater abrasion, razor-blade cuts, and a proper cross-hatch tape test (tic-tac-toe scoring, tape on, pull). Not a single section lifted.

I also filmed the tile boiling and holding at ~180 °F to show how Fusion Lock™ chemically welds the new surface to the old. A separate control tile (without the silane system) peeled easily—on video. Fair warning: you will hear my Labrador puppy, Huck, trying to “help” in the background, I had to go with that take because this was the tile I had soaked, boiled, and abused. The point of these videos isn’t views—it’s straightforward evidence for homeowners.

Fusion Lock™ FAQ

What is Fusion Lock™?

Fusion Lock™ is a multi-silane bonding system I use before applying a permanent polyester porcelain glaze. It chemically welds into the old surface instead of sitting on top like standard epoxy or acrylic urethane paint.

How is Fusion Lock™ different from standard bathtub paint?

Standard refinishing “paint jobs” usually rely on epoxy or acrylic coatings with minimal bonding prep. Fusion Lock™ uses deep cleaning, moisture control, micro-etching, and a silane-based tie coat so the new glaze becomes part of the old surface instead of a weak film that can peel or flake.

Can Fusion Lock™ be used on both bathtubs and tile?

Yes. I use Fusion Lock™ on porcelain tubs, tile surrounds, and other compatible hard surfaces so the entire area bonds as a system integrating the Porcelain glaze into, not on top of the old surface.

Will Fusion Lock™ help prevent peeling and chipping?

The whole purpose of Fusion Lock™ is to address the failure points that cause cheap refinishing to peel. By controlling moisture, opening the surface correctly, and using a true chemical bond, the porcelain glaze is locked down into the Fusion Lock lasts for decades when cared for.

Is Fusion Lock™ low-odor and homeowner friendly?

Fusion Lock™ is part of a low-VOC system I use so the home does not smell like harsh industrial solvents for days. Porcelain Glaze is low V.O.C. and Isocyanate free. Residual odor dissipates in about 1 hour.
