Application Steps

  1. 1

    Surface Preparation

    The surface to be treated must be sound and clean. Loose, blistered paint layers and weak plaster fragments must be scraped off. Cracks and voids must be repaired with a repair mortar such as FOX SLIM MORTAR FC105. Once the surface has been freed of dust and dirt, the product can be applied directly.

  2. 2

    Mixing

    FOX MS BARRIER must be stirred with an electric mixer at 400–600 rpm before use.

  3. 3

    Dilution

    FOX MS BARRIER must not be diluted; it should be used directly.

  4. 4

    Application as Primer

    Apply one coat of FOX MS BARRIER to the surface first. On surfaces that have been exposed to heavy moisture or where mould is present, a second coat may be applied after a waiting period of 24 hours. If surface irregularities are present, surface levelling with FOX SILK MORTAR FC125 smoothing filler is carried out at least 24–48 hours after the FOX MS BARRIER primer application. At least 6 hours after the levelling, FOX PRIMERA® FL220 primer is applied. Depending on ambient conditions, after waiting 24–48 hours, a breathable paint (FOX INOVA MATT or FOX INOVA SILAN) is applied. If there are no surface irregularities, the breathable topcoat is applied 24–48 hours after the FOX MS BARRIER primer application.

  5. 5

    Application as Paint

    FOX MS BARRIER is applied as the first coat primer. If surface irregularities are present, surface levelling with FOX SILK MORTAR FC125 smoothing filler is carried out at least 24–48 hours after the primer application. At least 6 hours after the levelling, FOX PRIMERA® FL220 primer is applied. At least 6 hours after the FOX PRIMERA® FL220 application, FOX MS BARRIER paint is applied as the topcoat. If there are no surface irregularities, the FOX MS BARRIER topcoat is applied at least 24 hours after the primer application.

  6. 6
