Nitoprime 25

​Fosroc Nitoprime 25 is a two-component epoxy primer designed to enhance the adhesion and corrosion protection of concrete and steel surfaces. It is particularly effective when used in conjunction with Fosroc's range of flooring and coating systems.​

Key Features:

• Active Corrosion Control: Provides effective protection against corrosion for both concrete and steel substrates.​

• Enhanced Adhesion: Improves the bonding of subsequent Fosroc coatings and flooring systems, ensuring long-lasting performance.​

• Versatile Application: Suitable for application over both abrasive blast-cleaned and manually prepared surfaces.​

• Ease of Use: Can be applied by brush, roller, airless spray, or conventional spray, offering flexibility in application methods.​

• Extended Open Time: Offers a prolonged open time, facilitating efficient application without rushing.​

• High Wetting Characteristics: Ensures thorough penetration and sealing of porous substrates, enhancing the effectiveness of subsequent coatings.​

Recommended Applications:

• Concrete Surfaces: Ideal for priming concrete substrates before applying Nitoflor SL2000/4000, TS/TF resin-based floor toppings, Nitocote protective coatings, or Nitomortar epoxy repair mortars.​

• Steel Surfaces: Provides corrosion protection and improved adhesion for steel substrates used in various construction applications.​

Application Guidelines:

1. Surface Preparation: Ensure surfaces are clean, dry, and free from contaminants. For steel, abrasive blast cleaning to SA2½ is recommended; for concrete, manually prepared surfaces should meet St 3 standards.​

2. Mixing: Combine the base and hardener components as per the manufacturer's instructions, mixing thoroughly to achieve a uniform consistency.​

3. Application: Apply the mixed primer evenly using the chosen method (brush, roller, spray), ensuring a continuous film without over-application.​

4. Drying: Allow the primer to dry to a tack-free condition before applying subsequent coatings. Drying times may vary based on temperature and humidity conditions.​

Safety Precautions:

• Storage: Store in a cool, dry place, away from direct sunlight and sources of heat. Ensure containers are tightly sealed when not in use.​

• Handling: Use appropriate personal protective equipment, including gloves, goggles, and respiratory protection if necessary, during application. Ensure adequate ventilation in the application area.​

• First Aid: In case of contact with eyes or skin, rinse immediately with plenty of water. If ingested or if adverse reactions occur, seek medical attention promptly.
