Galvanized Corroded Steel: No Blasting Required

Galvanized steel is widely used because its zinc coating resists corrosion. Once that zinc layer begins to break down, however, rust can creep in and traditional coatings often struggle to adhere. Restoring corroded galvanized steel typically involves aggressive blasting or chemical etching to remove oxidation and roughen the surface, and even then adhesion can be unreliable. NanoPrime™ offers a simpler solution by chemically reacting with the weathered galvanized surface itself.

NanoPrime chemically reacts with weathered galvanized surfaces. Preparation is straightforward: pressure wash to remove oil and dirt and apply a coat of the primer. No sand or grit blasting is needed for corroded areas, and any light or heavy rust left behind will be converted into iron phosphate, a corrosion‑resistant compound. On new galvanized steel, an etch may be necessary to remove chromates for proper adhesion, but corroded areas benefit directly from the primer’s chemistry.

Because NanoPrime bonds chemically rather than mechanically, it eliminates the need to roughen the metal. The patented formulation forms a chemical bond with the substrate that has greater adhesion and corrosion resistance. Rust on galvanized steel is transformed into a stable phosphate layer that becomes part of the coating, stopping further corrosion. This approach provides a reliable foundation for high‑performance topcoats without the waste and mess associated with blasting.

The water‑based nature of NanoPrime makes it particularly suited to galvanized applications. The coating can be applied in high humidity, on damp surfaces and in salt‑air environments such as offshore platforms or coastal facilities. Humidity, dampness and salt do not adversely affect adhesion or performance. Since the primer contains no VOCs, is non‑toxic and non‑flammable, crews can work safely and store product without special permits or protective gear.

Infrastructure projects that use galvanized steel, such as bridges and transmission towers, benefit from NanoPrime because it eliminates the need for sand blasting and contains no VOCs. By simplifying surface preparation to a pressure wash and leveraging chemical bonding to handle rust, NanoPrime enables faster maintenance, reduces environmental impact and delivers long‑term corrosion protection for galvanized structures.
