APPLICATION

  • Apply BAUTECH CD HARD a with metal trowel.
  • For a smooth finish use the dry roller on the surface making he movements as if you were painting, this procedure removes marks from the trowel ande vens the surface.
  • To improve the surface finish, use sandpaper between 2 – 24 hours after application, otherwise it will be difficult to sand.
  • Expansion joints must be respected
  • It is recommended to use a package at a time, because the working time of the material is short
  • For applications above 200 mil (5.0 mm), it is recommended to perform the process in layers le, applied two or three layers, with 2 hours intervals.

OPEN FOR TRAFFIC:

  • 6 hours after the application (vehicles with tires).
  • For any type of paint, 24 hours after full application
