The innovative solution: Renovating foil roofs with liquid plastic and fleece
This is how the foil roof renovation with liquid plastic and fleece works:
-
Thorough cleaning & preparation:
We remove dirt, leaves, and algae from your roof and check the general condition of the old membrane.
-
Local repair:
Damaged areas are repaired in advance to create a solid base.
-
Priming the entire roof surface:
A system-compatible primer (Purgrund) is applied to promote the bond between the membrane and the liquid waterproofing membrane.
-
Homogeneous integration of all structures, inlets, and penetrations:
Integration of all details such as skylights, inlets, parapets, etc. into the roof surface (with a minimum of 10 cm of fleece inlay into the roof surface).
-
Coating the entire roof surface with PURelastik liquid waterproofing membrane & fleece:
Applying the Purelastik liquid waterproofing membrane in the fleece-reinforced system using a spraying method (airless). This creates a seamless, homogeneous waterproofing system.
