CASE STUDY
FUEL TANK CORROSION PROTECTION
NanoPrep protects fuel tanks without abrasive blasting
Industry: Oil & Gas
Application: Fuel Tank Corrosion Protection
Products: NanoPrep
Customer Location: : Qld, Australia
Application Date: Oct 2025
PROBLEM
A 110,000-litre above-ground carbon-steel diesel tank in Queensland, required a high-performance anticorrosive coating system. Year round rain and condensation creates a high risk of under-film and crevice corrosion, especially at saddle supports and tank-to-concrete interfaces. In addition, the coastal environment adds airborne chlorides which accelerates corrosion, while continuous sunlight and elevated surface temperatures demand a UV-stable, heat-tolerant topcoat to prevent premature coating degradation. Given the limited clearance beneath the tank and the presence of adjoining critical infrastructure, abrasive blasting for surface preparation was not feasible; therefore, an alternative method was required.
APPLICATION
NanoPrep was chosen as the preferred surface-preparation method since it offers an effective, long lasting, low-cost alternative to abrasive blasting using a simple low-pressure power wash (3,500 psi) combined with power-tool cleaning. NanoPrep’s unique technology allows it to penetrate deep into existing painted surfaces for high adhesion and acts as a tie coat for many compatible topcoats.
NanoPrep eliminates the need for abrasive blasting, enabling surface preparation via a simple low-pressure wash. It applies easily by roller, brush, or airless spray and is well suited to tight or difficult-to-access areas.
Upon application of NanoPrep to the substrate, Nanofusion takes place enabling deep penetration into the rusted substrate to create a stable, high-bond strength base suitable for non-solvent or low-solvent top coats.
OUTCOME
NanoPrep enabled effective surface preparation using low-pressure washing and power-tool cleaning, avoiding the excessive cost and downtime of abrasive blasting.
The coating system delivered strong adhesion and robust corrosion resistance at saddle supports and tank-to-concrete interfaces, and a compatible UV-stable, heat-tolerant topcoat suited to Queensland conditions was successfully applied.
The outcome is extended service life, protected fuel quality, and simpler future maintenance.

Products
NanoPrep
NanoPrep’s surface preparation technology allows industrial coating application in areas where it is difficult, cost prohibitive or impossible to perform surface preparation by abrasive grit blasting.
NanoPrep is a one component, waterborne, acrylic co-polymer composition that reacts and cross-links with rusted steel surfaces, clean steel, painted steel, aluminium, and/or galvanised steel surfaces creating superior anticorrosive properties. NanoPrep is non-hazardous, environmentally friendly and non-flammable. Can be applied to damp or dry surfaces as a primer or finish coat.
