## Surfaces & applications

Steel structures and sections; industrial containers; tanks and pipework; fabricated metal equipment

## A foundation for steel protection

Use the primer as the first layer of a compatible industrial corrosion-protection system. It suits fabricated steel, structural sections, pipework and containers where surface preparation and complete coverage are central to performance. Pair it with a compatible intermediate coat or topcoat for the required exposure.

## Choose the zinc-content grade

Source section: https://leadercoat.com/products/epoxy-zinc-rich-industrial-primer/#detail-2

30%, 50% and 70% variants are available. The selected grade should match the project specification and the rest of the coating system. The finish is matt grey; it is a primer rather than a decorative colour-matched topcoat.

## Two components in measured kits

The 4.4 kg kit contains 4 kg base and 0.4 kg hardener; the 22 kg kit contains 20 kg base and 2 kg hardener. Maintain the 10:1 weight ratio when dividing a kit. Mix only the quantity that can be applied and use compatible thinner after the base and hardener have been mixed.

## Coverage and coat build

Source section: https://leadercoat.com/products/epoxy-zinc-rich-industrial-primer/#detail-4

The reference coverage is approximately 5 m²/kg for one coat. Rough steel, complex shapes, application losses and increased film thickness reduce practical coverage. Apply two even coats where specified and pay attention to welds, edges and difficult-to-reach features.

## Application environment

Source section: https://leadercoat.com/products/epoxy-zinc-rich-industrial-primer/#detail-5

Apply to a dry, prepared substrate above 3°C and avoid rain or fog during coating work. Remove rust, loose material, grease and contamination before application. Keep the coating protected during the early drying period; full hardening takes approximately 3–7 days under suitable conditions.

## Application procedure

1. **Prepare steel**

   Remove rust, oil, loose coatings and dust to the preparation level required by the coating system.

2. **Mix 10:1**

   Stir the base thoroughly, then combine with hardener at 10:1 by weight. Adjust with compatible thinner for the application method.

3. **Apply evenly**

   Brush or spray an even coat, including edges and welds. Use the specified coat count and allow approximately 3 hours between primer coats.

4. **Dry and overcoat**

   Protect the fresh film from moisture and contamination. Apply compatible subsequent coats according to the complete system requirements.

## Frequently asked questions

### Is this the final decorative finish?

It is a matt-grey anti-corrosion primer. Choose a compatible finish coat when colour, gloss or the exposure specification requires one.

### What is the mixing ratio?

Mix base and hardener at 10:1 by weight. Both standard kit sizes follow this ratio.

### Which zinc grade should I order?

Choose the 30%, 50% or 70% grade according to the coating specification, exposure and compatible topcoat system.
