Description
Professional hydrochloric acid for removing mortar haze, efflorescence, and for etching concrete prior to coatings or adhesives. The 5 L pack balances portability with ample capacity for multiple areas or repeated treatments. Always dilute and pre‑test in a discreet spot. Rinse thoroughly to remove residues and neutralise as required. Avoid use on acid-sensitive stone and galvanised surfaces. Wear gloves, goggles, and protective clothing. Store upright in a cool, ventilated area away from incompatible materials and ignition sources.
