Fosroc Nitoprime 330 Primer 20L

Code: 40-FC605120-20L
U.O.M. - Each
High-performance primer for Cemtop cementitious flooring systems. Fosroc Nitoprime 330 is the recommended primer for the Cemtop cementitious flooring systems when applied to concrete and cementitious screeds. The primer film forms and seals the substrate to prevent air release which could otherwise cause pinholes in the floor topping. It wets out the substrate, promotes adhesion and prevents desiccation of the Cemtop.

Details

Fosroc Nitoprime 330 is the recommended primer for the Cemtop cementitious flooring systems when applied to concrete and cementitious screeds. The primer film forms and seals the substrate to prevent air release which could otherwise cause pinholes in the floor topping. In addition it wets out the substrate, promotes adhesion and prevents desiccation of the Cemtop. Nitoprime 330 is a water-based a single component white liquid which dries clear.

Features:

  • Excellent adhesion to concrete and cementitious screeds
  • Seals the substrate to minimise pin holing
  • Excellent water resistance after film formation
  • Economic, easy to use with no restrictive pot life
  • Ideal for:

  • Using as a primer for Cemtop cementitious flooring systems
  • APPLICATION

    Surface Preparation:

    Use on sound concrete and cementitious screeds that are free from surface contamination and have been well prepared. It should not be used on oil contaminated concrete or existing epoxy toppings.

    Mixing:

    Nitoprime 330 is the primer for Cemtop flooring systems and other cementitious levelling screeds. For specific dilution factors and application procedures regarding Nitoprime 330, please refer to the relevant product Technical Data Sheet.

    Placement:

    Two coats of primer are recommended to ensure that the substrate is fully sealed and to minimise the likelihood of pinholes in the topping. The first primer application is carried out after the existing concrete floor has been prepared and cleaned. Nitoprime 330 is diluted in the ratio of 1:5 (primer to clean water by volume). It is applied and worked into the floor by broom. The primer should not be applied by roller or spray.

    The second coat of primer should be diluted in the ratio of 1:3 (primer to clean water by volume). It should be carried out when the first coat is dry. If the floor is porous, it may be necessary to prime a third time at a ratio of 1:3. The primer must be well brushed into the surface. Ponding of the primer must be avoided because this can lead to failure at the bond line.

    During application the area should be well ventilated to speed the drying of the primer. The application of Cemtop screed can proceed as soon as the second application of primer has dried. Where a dual layer Cemtop system is being applied, the base layer should be primed with Nitoprime 330 as soon as the first layer has hardened.

    Clean Up:

    Remove from tools, equipment and mixers with clean water immediately after use. Dried material can only be removed mechanically.

    Storage:

    Shelf life of 18 months if stored in the original unopened container.

    Yield:

    Covers approximately 10 - 20 square metres per litre, per coat, after dilution with water.
