Product Intelligence
Primer 4 - Non-Porous Surface Primer Technical Details
Product Overview
Primer 4 is a specialized primer product manufactured by Fosroc designed specifically for preparing metal surfaces and other non-porous materials before the application of protective coatings and waterproofing membranes. The product is engineered to improve adhesion to surfaces that do not readily absorb liquids, ensuring optimal performance of subsequent coating systems.
Product Specifications
Packaging and Supply
Primer 4 is supplied in 250 ml cans with the product code FC965207-250ML. This convenient container size makes it practical for both small-scale and medium-scale applications where targeted surface preparation is required.
Application Coverage
The product offers efficient coverage at a rate of 4 to 5 square meters per 250 ml can, allowing for economical use and effective material planning for project estimation and procurement purposes.
Drying Time Requirements
Primer 4 requires a minimum drying time of 15 minutes before the application of subsequent topcoat systems. This relatively short drying period facilitates efficient workflow and enables timely progression to the next application stage without extended delays in construction schedules.
Primary Applications
Metal Surface Preparation
Primer 4 is specifically formulated for use on metal surfaces, serving as an essential preparatory coating before applying protective membranes and coatings. The product creates a bonding bridge between the metal substrate and the topcoat system.
Compatible Topcoat Systems
Primer 4 is recommended for use prior to application of the following Fosroc protective membranes:
- Nitoproof 750 - A waterproofing membrane system
- Nitoproof 910 - A protective waterproofing coating
- Nitoseal PU400 - A polyurethane-based sealant
Adhesion Enhancement Function
Primer 4 is specifically engineered to improve adhesion to non-porous materials such as metals. By creating an intermediate layer between the smooth, non-absorbent metal surface and the topcoat system, Primer 4 ensures that subsequent coatings achieve optimal mechanical and chemical bonding, thereby enhancing durability and performance of the complete protective system.
