Acid Cleaning Runoff Leaves Calcium Salt Residue That Blocks Primer Penetration

An Altona North chemical storage facility had a hardstand used for tank washing and chemical cleaning operations. Acid cleaning products — used to clean storage tanks before product changeover — had been running off onto the hardstand concrete for years. The surface looked sound and was adequately clean on our visit. But prior pull-off testing would have flagged the issue.

We primed and marked. Within six months, adhesion failure appeared in the areas closest to the drainage points — where the highest acid runoff concentration had accumulated. The acid had deposited calcium carbonate salt residues in the concrete pores through a reaction with the cement matrix, reducing the surface's ability to absorb and bond with epoxy primer.

Pull-off adhesion testing before full primer application is the diagnostic step for any chemical facility hardstand with confirmed acid exposure. If pull-off results are below 1.5 MPa on test patches, the calcium salt residue in the pores needs to be removed with a high-pressure rinse and a neutralising wash before priming. We learned this at Altona North. It's now standard on every chemical facility hardstand where acid cleaning is part of the operations.

Altona North is the port-adjacent chemical storage and manufacturing corridor in Hobsons Bay — chemical logistics, manufacturing, and the western industrial businesses near the RAAF Williams gate. VicRoads approved. Pull-off adhesion test is standard before full primer on every Altona North chemical facility hardstand.

Acid cleaning products react with the calcium compounds in the concrete cement matrix, dissolving and redepositing calcium carbonate as a white crystalline salt in the concrete pores. These calcium salt deposits block the pore structure that epoxy primer needs to penetrate for adhesion. The surface may feel and look clean, but the pores are partially blocked.

Yes. High-pressure fresh water rinse (3,000-4,000 PSI) followed by a dilute neutralising wash (sodium bicarbonate solution) dissolves and flushes the calcium salt deposits from the pores. Conductivity test of the rinse water confirms when the surface is adequately clean. Pull-off test after cleaning confirms adhesion has been restored before full primer application.
