It is important to realise that the installation of hidden doors includes several stages.
At the first stage, the aluminum profile is mounted together with the door leaf to minimize gaps during installation.
The first stage occurs before finishing the walls. After which, the prepared door leaf is removed and sent for revision (painting, veneering). At this time, the construction crew are finishing the walls on the site – putty, primer and paint the walls.
The second stage is the installation of the door leaf and handles.
