Which adhesives and sealants should be used to apply HERTALAN®?

For installation of our roofing systems you must distinguish between:



Surface adhesion

In a partially or fully bonded system, the Hertalan sheet is attached to the substrate with an adhesive. This can be one-sided with a PU adhesive (hertalan ks143) or with a two-sided contact adhesive (hertalan ks205). In a hertalan easy cover system the seams are created with an adhesive connection. This is only possible using hertalan ks137 contact adhesive in combination with a seal of hertalan ks96 (adhesive sealant).



In een hertalan easy cover systeem worden de naden aangebracht met een lijm-kit verbinding. Dit kan alleen door een combinatie van de EPDM lijmen hertalan ks137 en afsealen met  hertalan ks96 (adhesive sealant).


Fixation to perimeters and edge

All roof perimeters and edges have to be fully adhered regardless of which system is used. Only hertalan ks137/205 contact adhesives should be used in these areas with ks96 used for sealing off where necessary.


Adjacent brickwork and other upstands

The same rules apply for this application as for the perimeter and edge fixation. We advise you to always consult the HERTALAN® installation guidelines.
