WATER TANK CORROSION PROTECTION 

APPLICATION

NanoPrep was selected as the preferred surface preparation method as it provided an effective and cost-efficient alternative to abrasive blasting. Surface preparation was completed using a combination of low-pressure power washing (3500 psi) and power tool cleaning, eliminating the need for costly containment and lead paint removal procedures.

Before coating work commenced, several structural repairs were required due to severe corrosion damage. The tank underside had extensive pitting, while some of the steel column supports had deteriorated to the point where sections of steel were completely missing.

Belzona 1111 (Super Metal) was used to repair the pitted areas on the tank underside, rebuild lost steel sections, and cold bond reinforcement plates onto the damaged steel supports, restoring structural integrity without the need for hot work.

Once the repairs had fully cured, the steel supports and surrounding areas were coated with two coats of NanoPrep, followed by two coats of R230 TopCoat.

The tank sides and roof were also protected using NanoPrep and R230 TopCoat.  Again, surface preparation required only high-pressure water washing, eliminating the need for abrasive blasting. Brushes and rollers were used to stripe coat weld seams, edges, and difficult-to-access areas prior to spray application.

Two coats of NanoPrep and two coats of R230 TopCoat were then applied by airless spray, providing long-term corrosion and UV protection. Both products proved highly user-friendly due to their single-pack formulation, allowing for efficient and straightforward application.

OUTCOME

The project was successfully completed in just five days, with severely corroded areas repaired using Belzona and protected with NanoPrep and R230 TopCoat.

By eliminating the need for abrasive blasting, the project avoided the high costs and delays associated with containment and lead paint removal, while still delivering a durable, long-term corrosion and UV protection system for the tank and supporting steelwork.

Belzona 1111 (Super Metal)
A 2-part repair composite for metal repair and resurfacing based on solvent-free epoxy resin reinforced with silicon steel alloy. This repair material will not corrode and resists a wide range of chemicals. It is easy to mix and apply without the need of specialist tools and can be machined using conventional tools.

NanoPrep Rust Primer & Anticorrosive Industrial Coating 
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.

R230 TopCoat
ReziSafe R230 Top Coat is a Mid Gloss, ‘single pack’ self cross linking industrial waterbased top coat that offers excellent surface protection. ReziSafe R230 has been developed as an ideal topcoat for NanoPrep which can successfully prime damp rusty surfaces, galvanised steel, aluminium or stainless steel with minimum surface preparation. R230 provides UV protection so it can be used to protect against external elements.
