Fosroc – Nitoseal Primer MS2


Nitoseal Primer MS2 is a two-component solvent-based epoxy resin primer designed for priming before application of the sealant. The 750ml packs are easy to apply and have exceptionally strong adhesion properties.


Empty the entire contents of the hardener tin into the base tin, replace the base tin lid. Mix thoroughly, by shaking for 2 minutes.

Prime the joint face using a clean dry brush. Avoid over-application of primer causing puddles in the bottom of the joint.

Sealants should be applied between 30 minutes and 4 hours after priming. If the joint is not sealed overnight the primer film should be removed by grit blasting or grinding and the joint reprimed.

The mixed Primer MS2 must be applied within one working day. Do not use part packs.


Clean equipment immediately after use with Fosroc Solvent.


Primer MS2: 500 ml can
