Watco Galvaprime
Litres required: 0.00L
Based on 20.0 m² per litre- Lightwork of heavy-duty repairs
- Structural strength solutions
Watco Galvaprime is a preparatory wash for galvanised and zinc surfaces before applying a compatible paint or coating. It treats the metal surface to improve adhesion, helping the following coating bond where untreated galvanising can be difficult to paint.
The single pack liquid is applied by brush and is designed for same-day preparation and overcoating. The treated surface turns black as the wash reacts, giving a visible indication of successful treatment on a properly cleaned substrate. Use Galvaprime as the preparation stage of a suitable coating system rather than as a decorative or weatherproof finish on its own.
- Preparatory treatment for galvanised and zinc metal.
- Brush application with visible blackening of the treated surface.
- Overcoat the same day within the specified interval.
Surface Preparation
Remove oil, grease, dirt and excess rust before treatment. The surface must be sufficiently clean for the wash to react evenly. Check the intended topcoat's suitability for the substrate and the complete preparation system. Where heavy contamination prevents an even reaction, further cleaning or treatment is required rather than painting over the problem.

Coverage
Approximately 20m² per litre. Apply evenly to the prepared galvanised or zinc surface, working into details as needed. Actual consumption can vary with the shape and condition of the metal.
Directions for Use
- Brush the liquid evenly over the cleaned surface.
- Allow the treatment to react and dry. The surface should turn black; failure to blacken can indicate contamination or rust affecting the reaction.
- The technical sheet recommends washing the blackened surface with clean water and allowing it to dry before painting.
- Apply a compatible coating once the surface is dry. Typical touch drying is about two hours at 20°C, and the manufacturer says not to exceed sixteen hours before overcoating.
Limitations
For preparation of suitable galvanised or zinc surfaces within a compatible coating system. It is not a substitute for cleaning and does not provide a finished protective coating by itself. Do not apply below 4°C. The product contains flammable solvent and acidic components; follow the GB safety sheet and product label. Protect from freezing and rinse application tools thoroughly with water as directed.
Product FAQs
What does Galvaprime do?

Why does the metal turn black?
Blackening is the visible reaction described by the manufacturer. If it does not occur, contamination or rust may be interfering with treatment.
Can I paint the same day?
Yes, once the treated and rinsed surface is dry. Do not exceed sixteen hours before applying the specified topcoat.
Is it a finished metal paint?
No. It is a preparatory wash and needs to be followed by a compatible protective or decorative coating.
