Substrate must be dry, clean, dust-free and grease-free. Keep the packaging well closed until the moment of use. Open the tin and puncture the film. Do not use Prep M direct from the original packaging. Pour as much Prep M into a glass or tin as can be used within 30 minutes and close the tin again immediately. Prep M must not be applied in too thick a coat. Firmly rub the surface to be treated with a clean, fluff- and dye-free cloth or tissue paper, wetted with Prep M. In this way the surfaces will be cleaned and pretreated in one operation. Replace the cloth or tissue when dirty. After a drying time of approximately 5 minutes (solvents must evaporate) the adhesive can be applied. Best results are obtained when the bonding is performed within six hours after application of Prep M. Therefore do not apply more Prep M than can be bonded within six hours Avoid contact with the pretreated surface, as this may adversely affect adhesion.
Consumption: The consumption of Prep M is approx. 20 m2 per 1 liter.


  1. Due to its poor paint compatibility Prep M should not be applied to areas that will be painted afterwards. Adjacent areas can be covered with masking tape or similar so that Prep M is only applied where the adhesive or sealant will be used. Another option is to remove the fresh primer layer prior to painting, through the use of Bostik Cleaner 14, Cleaner I or Liquid 1 for example. Test the cleaner first to ensure it will not damage the surface.
  2. If a surface is badly contaminated, clean first with a product such as Cleaner 14.Test the cleaner first to ensure it will not damage the surface.
  3. Use of Prep M can adversely affect the adhesion of tapes.


Store in cool, dry conditions between +5 and +30 °C. Prep M has a shelf life of at least nine months in unopened original packaging.
