Primer 21 - Fosroc Technical Details
Overview
Primer 21 is a single-component primer product supplied by Fosroc in 250ml containers with the product code FC965228-250ML. It is specifically formulated to achieve optimum adhesion when applying sealants to concrete and other porous materials.
Key Features and Applications
Primer 21 is primarily recommended for achieving optimum adhesion to concrete and other porous materials. It is particularly utilized when applying Nitoseal PU400, a polyurethane joint sealant, where it serves as the preferred priming system for porous substrates.
The primer offers excellent adhesion properties to clean, dry, uncontaminated concrete surfaces and most porous building materials. In most applications requiring optimal adhesion to concrete and other porous substrates, Fosroc recommends Primer 21 as the standard priming solution.

Application Context
Primer 21 is recommended as an alternative to other primers in the Fosroc primer range. While Primer 13 is reserved for applications involving water immersion, and Primer 24 is considered for excessively porous or friable surfaces, Primer 21 serves as the standard primer for general porous surface applications where good adhesion is required without water immersion concerns.
