DS Desert Shield 40 180 APP
4 mm thick, APP modified bituminous membrane, reinforced with non woven polyester mat
Description
High Performance polymer (APP) modified bituminous membrane, reinforced with
180 g/m2 non-woven polyester mat. The polyester combines high tensile strength and
elongation. The specially used polymer modifier has a great resistance to Ultra-Violet
radiation.
Features
• High flexibility at low temperature and stability at high temperatures
• Durable and easy to apply
• Remarkable resistance to aggressive attack of salts and chemicals
• High tensile strength and elongation
• Excellent tear and puncture resistance
Function
Used as single layer as tanking in basements or for waterproofing of roofs. A single
layer followed by a layer of mineral surfaced DS can be used for exposed roofs.
Instructions for Application
The membrane can be installed fully bonded or loose-laid by torch welding.
The substrate should be cleaned and primed with AWAZEL PRIMER D 41 and
allowed to dry. Torching should be done by skilled workers and should be controlled
so that only the PE film is melted and the asphalt coating is softened sufficient to
bond the membrane. All lap joints should be smoothed and sealed using a heated
round-nosed trowel. The heat of the gas flame should be applied to the trowel. In
loose-laid applications, only the lap joints, areas around penetrations (pipes etc.),
upstands and a 30 cm wide strip around the perimeter of the work should be fully bonded.
Upstands and flashings should be installed using 1 M wide pieces cut from the length of
the roll. (The overlap joints should be 5 to 10 cm at the sides and 15 cm at the end)
Coverage
1.12 m per layer for flat surfaces
Health & Safety
All safety measures should be taken during application. Fire extinguishers should be
available on the site. Workers should wear on personnel protective tools such as gloves
and goggles during application.
Packing
It is produced in rolls of 1 x 10 meters. The rolls are palletized and shrink-wrapped.
Surfacing
Standard surfacing is fusible P.E. Film on both sides. Different combination of to surfacing
are available upon request such as sand, coloured minerals, etc…
Storage & Material Handling
The rolls should always be stored vertically in a shaded area. Normally the pallets should
not be stacked one over the other. However, if a wooden board is used in between, two
pallets may be stacked one over the other.
