■ Key Features
96% zinc in dry film — long-term cathodic protection
Excellent rust prevention and weathering resistance
Strong adhesion, good recoatability
Easy application by brush, roller, air or airless spray
Safe and environmentally friendly to apply
■ Designed Uses
Long-term corrosion protection of steel. Can be used as a single coat or combined with matching heavy-duty coatings for full systems. The best material for replacing or repairing hot-dip galvanized and thermally sprayed zinc layers — on steel structures, bridges, tanks, marine components and castings.

■ Surface Preparation
New steel: remove oil and grease with a suitable cleaner, rinse off salts and contamination with fresh water. Remove weld spatter and grind welds and sharp edges. Blast-clean to Sa 2.5 (ISO 8501-1), surface roughness Rz 40–75 µm (medium G, ISO 8503-1). Ideally coat within 4 hours after blasting.
Galvanized surface repair: remove oil and grease thoroughly, wash off salts with high-pressure fresh water, grind small rusted areas with power tools and repair with this product.
Apply at −5 to 50 °C and relative humidity ≤ 95%; steel temperature must be at least 3 °C above dew point. Do not apply outdoors in rain, fog, snow, strong wind or heavy dust. Watch for dry spray in hot summer weather; provide strong ventilation in confined spaces and during drying.
■ Drying & Recoat Interval
| Steel temperature |
5 °C | 15 °C | 25 °C | 35 °C |
| Touch dry | 2 h | 1 h | 30 min | 20 min |
| Hard dry | 5 h | 4 h | 2 h | 1 h |
| Recoat (min) | 2 h | 1 h | 30 min | 20 min |
| Sealer topcoat (min) | 36 h | 24 h | 18 h | 12 h |
Maximum recoat interval: unlimited — surface must be clean, dry and free of zinc salts before the next coat.
■ Typical Coating System
Apply directly over steel blast-cleaned to Sa 2.5 / St 3, or over hot-dip galvanized and thermally sprayed zinc surfaces. Recommended overcoats: zinc sealer, metallic sealer, silver metallic finish, silver zinc-rich coating, zinc-aluminium coating.
■ Packaging & Storage
25 kg — Flash point: above 47 °C. Store dry, cool and well ventilated, away from heat and fire; keep containers tightly closed. Shelf life: 2 years under good storage conditions.
■ Health, Safety & Environment
Contains flammable solvents. Follow national and local safety regulations on site. Read the safety label and the Safety Data Sheet (SDS). Avoid inhaling solvent vapour and paint mist; avoid skin and eye contact. Use only with strong ventilation, especially in confined spaces. Dispose of waste according to local regulations.
