Desmopol is a highly elastomeric continuous waterproofing
membrane that can be installed in a single layer with excellent
adhesion to all types of surfaces. Desmopol holds an ETA Certification
for 25 years life expectancy, making it an ideal solution for
waterproofing new builds or restorations.
Desmopol Liquid Membrane comes in 25kg drums and 2Lt tins
of Accelerator. Pallet quantity 36 sets : 36 drums of 25kg + 36 tins
of 2Lt Accelerator.

1 Preparation of surface: It should
be clean, dry and free from any
contaminants such as oil, grease
and dust. Loose chippings must be
removed and any cracks and splits
in substrates to be repaired with
PU mastic.
2 Specific areas, such as structural
joints and perimeter flashings with
walls, should be prepared using
Tecnoband Mat embedded in a coat
of Desmopol.
3 For Plywood/OSB decks or
insulation joints must be taped
using Tecnoband Mat.
4 Overlaps on metal surfaces must be
taped with Tecnoband 100 to avoid
damage to the Desmopol Membrane.
5 Work out the area you will cover
with the 27kg tin of mixed product
(please check coverage rates for
different guarantees available), do
not spread the product too thin.
6 Pour the Accelerator into the
Desmopol Membrane tin and mix on
slow speed using a paddle mixer or
similar until the products are visibly
mixed (approx. 2mins).
To avoid the presence of air bubbles
the product must be mixed with a slow
speed paddle mixer.
Important Note: The Accelerator
must be mixed at the exact ratio of
2Lt tin for 25kg. Do not modify this
ratio as this may result in an incorrect
chemical reaction. Exact ratio of 110ml
per each Litre of Desmopol.
7 Desmopol is self levelling, do not
overwork the product.
8 Apply Desmopol on upstands, corners
and penetrations in 2 thin layers.
9 Apply Desmopol Membrane to the
designated area by squeegee, brush
or roller.
10 Desmopol will form a skin
after 30mins and be completely
waterproof, then walkable after
2-4hrs. Fully curing time is 24hrs.
11 Tecnotop 2C top coat can be used to
guarantee the stability of the colour
and must be used on guarantee
systems over 15 years.
Warm roof systems: PIR VV insulation
must be primed with EPW1070. Once the
primer is dry, Desmopol can be applied
directly on the PIR VV insulation boards.

Desmopol Membrane, when used in
conjunction with Accelerator can be
used directly on the substrate such
as: plywood/OSB, asbestos, metal,
lead, bitumen membranes,concrete,
asphalt, masonry or brick walls.
