How are the Quick-Step® profiles attached?
There are two kinds of profiles: • laminate covered plastic profiles (with a light brown rail) • laminate covered multiplex or MDF profiles (with a black rail). The laminate covered plastic profiles are attached to the laminate floor using light brown rails. You clasp the laminate floor between the profile. You can also glue the lower rail to the sub-floor with polystyrene-compatible glue. For the laminate covered multiplex or MDF profiles, you must attach the black plastic rail to the sub-floor with screws or glue (again, with a glue that is polystyrene compatible). If you need to bridge a height difference, you can also attach this black rail on and through the underlay. In this case, the only option is to use screws. Then you can install the laminate. Leave the usual expansion joint, using the spacers, along this plastic rail. To finish, remove the spacers and click the laminate profile in the rail.
