An acidic solution of a copper salt for the pre-treatment of clean zinc surfaces so as to provide a good key for paints which would otherwise show poor adhesion.

Apply to new galvanising within 7 days. Zinc surfaces which are contaminated should be cleaned down using an abrasive pad, water and cleaning agent followed by rinsing and allowing to dry. If contaminated with oil or grease surfaces should be wiped over with Universal Degreaser before carrying out the cleaning down procedure. Can be applied to weathered galvanised surfaces although reactivity of the treatment will diminish as the age of the galvanising increases and can result in an uneven colouration from light grey to dark grey. If no colour change take place, these areas should be considered as contaminated.

• Apply within 7 days of galvanising
• Touch Dry: 1.5-2 hours @ 20 °C
• Blue solution turning grey after application
• Coverage – 40 sq.m / litre
