Primer 4 - Technical Details and Specifications

Product Overview

Primer 4 is a specialized primer product manufactured by Fosroc designed specifically for metal surfaces. It serves as a preparatory coating to enhance adhesion and provide corrosion protection before the application of various protective membrane systems.

Primary Applications

Primer 4 is primarily used for priming metal surfaces before the application of Fosroc waterproofing membranes. The product is particularly suited for:

  • Metal substrates requiring adhesion enhancement before protective coatings
  • Ferrous metals that need anti-corrosion protection
  • Preparation for Nitoproof 750 and Nitoproof 910 membrane applications

Technical Specifications

Coverage Rate

Primer 4 is applied at a coverage rate of 4 to 5 square metres per 250 ml can, depending on the substrate surface condition and application method.

Drying Requirements

The product requires a minimum drying time of 15 minutes before the application of subsequent coating systems such as Nitoproof 750 or Nitoproof 910 can commence. This drying period ensures proper cure and adhesion to the substrate before overlying coatings are applied.

Product Supply

Primer 4 is supplied in 250 ml cans with the product code FC965207-250ML.

Key Features and Benefits

  • Enhances adhesion to non-porous metallic materials
  • Provides anti-corrosion protection on ferrous metals
  • Fast-drying formulation enabling efficient application workflows
  • Compact supply format suitable for targeted applications
  • Compatible with Fosroc waterproofing membrane systems

Surface Preparation Before Primer Application

Before applying Primer 4, metal surfaces should be:

  • Clean and abraded to expose bright metal
  • Wiped clean with Fosroc Solvent 10 to remove oils and contaminants
  • Free from paint, rust, and other contaminants that could compromise adhesion
  • Properly prepared to receive the primer coating

Relationship to Waterproofing Systems

Primer 4 functions as an essential preparatory step within waterproofing applications. Metal substrates treated with Primer 4 are then suitable for application of various Nitoproof waterproofing membranes, ensuring enhanced durability and corrosion protection performance of the complete system.
