Frequently Asked Questions
>What kind of surfaces is the nie wieder bohren system suitable for?
Almost any smooth or rough surface is suitable if it is firm and able to bear the load in question. The nie
wieder bohren system is perfect for high-quality materials that one does not want to damage by drilling.
nie wieder bohren is suitable with ceramic (tiles), stone, marble, granite, glass, concrete, metal, wood and
many plastics.
Unsuitable surfaces, on the other hand, include soft plaster, wallpaper, sheetrock and textiles (such as
carpets), which do not provide sufficient firmness and support for surface attachments:
There is no adhesion to polyethylene (PE), polypropylene (PP) and
polytetrafluoroethylene (PTFE, Teflon). These surfaces are rarely found in tub surrounds or bath
enclosures.
Although we have described as many examples as possible, our instructions can cover only some of
the many surfaces and surface treatments that are suitable. The user is therefore advised to make
preliminary tests when considering other types of surface.
>Will the system work on rough surfaces too?
Surface texture is not a factor that affects the bonding strength of the nie wieder bohren adhesive.
However, the surface must be flat to match the adapter and should not have any large gaps that would let
adhesive escape under the adapter ring. In fact, a slightly roughened surface affords even better adhesion
owing to the improved mechanical contact.
To completely remove the silicone-like adhesive from the gaps and pores of rough surfaces, it is
necessary to use a silicone remover, pure alcohol and a coarse brush.
