Isopon Zinc 182 Rust Inhibiting Primer Grey

Description

Isopon Zinc 182 Rust Inhibiting Primer – Grey

Isopon Zinc 182 is a high-performance anti-rust primer designed to stop corrosion in its tracks and provide a tough, long-lasting base for paint. Packed with zinc for superior protection, it’s ideal for use on cars, trailers, agricultural equipment, metal gates, railings and general steelwork where rust is a problem.

Engineered by U-POL’s Isopon range, Zinc 182 chemically inhibits rust formation and adheres strongly to bare metal, previously painted surfaces and even lightly rusted steel (once properly prepared). It can be over-painted with most topcoats, making it a versatile solution for both DIY users and professionals.

Key Features & Benefits

• Powerful rust inhibition
  Formulated with active zinc pigments that help prevent corrosion and stop rust from spreading underneath the paint film.

• Excellent adhesion to metal
  Designed for bare steel and lightly rusted surfaces, providing a solid, long-lasting key for topcoats.

• Durable, hard-wearing base
  Once cured, Zinc 182 forms a tough, chip-resistant coating that withstands everyday knocks, road grime and weather exposure.

• Compatible with most paint systems
  Can be overcoated with cellulose, acrylic, synthetic and 2K paints (check system compatibility on a small area first).

• Fast drying
  Touch-dry typically within 20–30 minutes (depending on film thickness, temperature and airflow), helping speed up your repair process.

• Ideal for automotive and general use
  Suitable for bodywork repairs, chassis, panels, trailers, machinery, garden furniture, gates and railings.

Typical Uses

• Automotive body panels and repair areas

• Chassis, sills and underbody components (when top-coated appropriately)

• Metal gates, railings and garden structures

• Agricultural and construction equipment

• General steelwork in workshops, garages and sheds

Surface Preparation

1. Clean – Remove all dirt, grease, oil, wax and road film with a suitable degreaser.

2. Remove loose rust & paint – Wire brush, sand or grind to remove loose/flaky rust and old paint.

3. Feather edges – Sand surrounding paint to a smooth feathered edge for a seamless repair.

4. Dry & dust-free – Ensure the surface is completely dry and free from dust before priming.

Proper preparation is essential for maximum adhesion and rust protection.

Application (Brush / Tin Version)

1. Stir thoroughly before and occasionally during use.

2. Apply in thin, even coats with a good quality brush or roller.

3. Allow the recommended drying time between coats.

4. Lightly sand if required before applying topcoat.

Overcoating

• Ensure the primer is fully dry before applying topcoat.

• Can be over-painted with most solvent-based and 2K automotive paints.

• For best results, lightly sand with fine abrasive (e.g. P400–P600) and remove dust before top-coating.
