Fosroc Nitoprime UR FS is a two component primer for use on concrete as part of the Nitoproof 800 system.
Particularly suitable for priming concrete elements such as balconies, walkways, flat roofs; covered / buried concrete decks including podium decks and green roofs; reservoir up stands and wind turbine plinth bases.
Fosroc Nitoproof 800 system is a polyurethane based waterproofing and crack bridging protection system. It provides a protective, durable, elastic, impervious, attractive surface which is easy to clean and maintain. The Fosroc Nitoproof 800 system is nominally 1.4mm thick and comprises one coat of Nitoprime UR FS, one coat of Nitoproof 800 Membrane and one coat of Nitoproof UVR Topcoat for exposed surfaces.

Application Notes
- Apply Fosroc Nitoprime UR FS at the required rate depending on the texture and porosity of the substrate
- Pour and drain the full contents of the hardener container into the base container and mix thoroughly with a slow speed electric stirrer fitted with an appropriate paddle, for a minimum of 3 minutes until homogeneous
- Spread immediately onto the substrate and apply by squeegee then over-roll with a short-haired roller to ensure even coverage, until the surface is completely wetted out
- If required, immediately apply Nitoflor Anti-Slip Grains by scatter (broadcast) at a consistent coverage of 0.3 to 0.5 kg/m²
- Allow to cure for 4 hours at 20ºC. If the primer has been left to cure for >48 hours then the primer should be removed and the area reprimed
- Priming onto damp substrates is possible using one coat of Fosroc Nitoflor DPM in lieu of Fosroc Nitoprime UR FS
- Coverage 10m² per 2kg pack (6m² - 16m² per 2kg pack dependent on substrate profile and porosity)
Limitations
- Do not use on substrates where rising damp or a potential osmosis problem may exist
- Do not proceed with application if atmospheric relative humidity is >90% or if the surface temperature is <3ºC above the dew point
- Application should not commence when the substrate temperature or the ambient temperature is, or is anticipated to be, <5ºC during the application or within the tack-free period
- For work in exposed areas, do not proceed with application if precipitation is imminent. Keep applied areas protected from precipitation until the applied layer is tack-free
- The design strength of concrete surfaces must be a minimum of 25MPa compressive strength at 28 days
- For car park decking systems use the Nitodek range of products
- All cracks, joints and upstands must be treated appropriately
