Primer HAMMERITE Metal Grunder Specialprimer 250 ml — metal primer for corrosion protection

HAMMERITE Metal Grunder Specialprimer 250 ml is a metal primer formulated to improve adhesion of topcoats and provide anticorrosion protection for ferrous metal surfaces. Supplied in a compact 250 ml container, this primer is intended for use on prepared or bare steel and iron to reduce rust formation and extend the service life of subsequent paint layers. The product is appropriate for small repair and maintenance work where a reliable base layer is required before applying decorative or protective topcoats.

Advantages

This primer offers improved adhesion between metal substrates and topcoats, helping to achieve a more uniform finish and longer-lasting paintwork. Its anticorrosion properties slow down the onset and progression of rust on ferrous metals when applied to prepared surfaces. The 250 ml size is convenient for small-scale tasks and touch-ups, minimising product waste while allowing precise application where needed.

Suitable for

• Priming gates, railings and fences prior to topcoat application
• Preparing radiators, valves and household metal fittings for painting
• Small repairs and refurbishment of metal components exposed to moisture
• Maintenance work on ironwork where surface rust has been removed and a protective base is required

Key specifications

• Container volume: 250 ml
• Intended substrate: ferrous metals (steel, iron)
• Main function: adhesion promotion and anticorrosion protection
• Application type: primer for use prior to topcoat/finish paint
• Typical use: small repair, maintenance and refurbishment tasks

How to use

Ensure the metal surface is clean, dry and free from loose rust, grease, oil and old flaking paint. Remove scale and loose corrosion by wire brushing or sanding, and degrease the area if necessary. Shake the primer container well before use and apply according to the manufacturer’s instructions for coverage and drying times. Allow the primer to dry fully before applying the chosen topcoat; follow the recommended drying interval and apply the finish in suitable environmental conditions to achieve optimal adhesion and protection.

Usage recommendations

Use on well-prepared metal surfaces for best anticorrosion performance. For severely corroded areas, remove as much rust as possible and consider using a rust converter or a more heavy-duty treatment before priming. Store the primer in a cool, dry place and follow safety guidelines on ventilation and personal protective equipment during application.
