For glueing and jointing of the various staff elements, it is recommended to use a slow-setting adhesive plaster coat designed for both operations.
Adhesives of this type, commercially available in the form of a powder partially composed of molding plaster, are perfectly suitable.
They may be used for touch-ups of joints.
These adhesives are available from our distributors, at building materials stores, or at wallpaper and paint retailers.
REMARKS: Paints, wallpapers and wall fabrics should be previously stripped or scraped off.
Before applying staff ornaments onto distorted surfaces, soak them thoroughly to restorc some flexibility.
In difficult cases, screw in the element, using one screw per linear meter.
