Introduction
In adhered systems the Monarplan® membrane is attached to the
substrate using an adhesive. The adjacent sheets of membrane
are then welded.
Icopal offers four types of adhesives depending on the membrane
used, and the type of substrate.
The Monarplan® GF Fleeceback membranes are fully adhered
using Icopal Single-ply Fleeceback adhesive, 3958 to the pre-
secured insulation board. For partly adhered systems (line
bonding) TK 400 is used.
The insulation boards are secured to the structural roof deck by
either mechanical fasteners, insulation adhesive (TK 395) or hot
bitumen, etc.

Preparing the substrate for refurbishment
The scope of the work necessary to prepare surfaces for
refurbishment - analysis of the roof built-up provided - depends
on the existing layers or plies.
• Existing bitumen covering with compressed gravel ballast
Cut open or completely scrape off blisters. Remove compressed
gravel ballast with appropriate tools and level the substrate.
Apply a compensation layer, e. g. a bituminous felt.
• Existing bitumen covering under loose gravel ballast
Remove gravel ballast and bonded, tightly adhered pebbles
with appropriate tools, e. g. water-proofing plane. If necessary,
even the substrate by additionally torching the surface. Level
any depression (e.g. removal of blisters or folds) by applying
welding tapes.
• Existing bitumen covering with a sand/grit coating
Cut open or completely scrape off blisters. Level any depression
(e.g. removal of blisters or folds) by applying welding tapes.
