Features & Benefits

• Designed for use as a primer/coating on cementitious surfaces which possess high levels of residual moisture
• Can be used where an integral dampproof membrane is either not present or not effective
• After curing, Nitoflor DPM provides a surface membrane with excellent adhesion to damp concrete
• Available in red and yellow as a visual aid for application and coverage
• Application by trowel/roller
• Hygrometer readings up to 98% RH within the substrate can be accommodated
• Suitable for use on new and old concrete floors
• Fosroc Nitoflor DPM is non-flammable
• Please refer to the Product Data Sheet for full details of:
  • Surface Preparation
  • Application Instructions
  • Coverage
  • Cleaning
  • Storage
  • Health and Safety

Application Notes

• Movement joints and cracks cannot be bridged using Fosroc Nitoflor DPM and should be filled with a flexible jointing material
• When using Nitoflor DPM as a damp tolerant primer, only one coat of 250 microns is required
• For a damp proof system apply a second coat at 90° (right angle) in a different colour to the previous cured coat
• For each coat it is essential that Nitoflor DPM is pinhole free and continuous, with absolutely no gaps or cavities. If this is not the case, an additional coat should be applied
• If a mechanical key is required, (normally if applying a screed or where application of a subsequent topping may be delayed) an additional coat of Nitoflor DPM should be applied with Fosroc Nitoflor Anti-Slip Grains

Please see the Product Data Sheet for detailed information.

Limitations

• Fosroc Nitoflor DPM is not suitable for use over under-floor heating systems
• Do not proceed with application if atmospheric relative humidity is, or is anticipated to be, >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
• The design strength of concrete surfaces must be a minimum of 25 MPa compressive strength at 28 days
• Fosroc Nitoflor DPM is not colour fast and may yellow over time
• It is important to assess the performance of Nitoflor DPM prior to applying high build polymer based systems please contact our Technical Department on 0113 2455450 (option 2) or send a message to [email protected] for advice
