Fosroc Nitoprime 25, 4L, Primer for Flooring & Coating Systems

It is versatile and suitable for hand or machine application on steel, concrete, masonry, fibreglass, timber, and other common substrates. It’s designed to bond well and provide a strong base for topcoats.

Key features include superior corrosion protection, high adhesion to substrates, low VOC and low odour properties, fast drying for reduced downtime, and elasticity that helps bridge minor cracks and joints while supporting inter-coat bonding for poxy-alkyd systems.

Nitoprime 25 is part of a three-coat system: a primer (Nitoprime 25) to promote adhesion, an intermediate coat, and a finishing coat. The primer provides excellent adhesion and compatibility with epoxy and alkyd topcoats, while the subsequent coats build the protective finish.

You can apply Nitoprime 25 by hand or machine, using brushing or rolling. The primer’s formulation supports uniform application across large or small areas. Follow the coating schedule and ensure a uniform film without runs or sags.

Nitoprime 25 is fast-drying and designed for rapid protection. For best results, follow the product data sheet’s recoat window guidance and allow adequate drying time between coats based on ambient conditions and substrate type.

Its elasticity and good wetting/adhesion properties allow it to accommodate minor substrate movements and bridge small cracks or crevices, helping to prevent premature coating failure and ensuring a smoother finish for inter-coat applications.

Yes. Nitoprime 25 has low VOC and low odour properties, making it suitable for indoor use where ventilation is limited, while still providing effective corrosion protection.

It’s commonly used to protect steel structures from corrosion, as a base primer before epoxy- or alkyd-based topcoats, and for rapid protection of large areas. It’s suitable for coating metal, concrete, masonry, fibreglass, timber and other surfaces in various environments.
