 Advantages and Benefits

- High dimensional stability.
- High tensile strength
- High puncture resistance
- Very good resistance to micro-organisms, putrefaction, mechanical impact, root penetration, natural aging, weathering, UV radiation and swollen.
- Excellent flexibility

- Limits strains and tensions in the waterproofing membrane due to the high temperatures and temperature changes to which will see under flat roofs.
- Absorbs structural movements.
- Presents good puncture protection to mechanical damage, derived from pedestrian transit, common in flat roofs.
- Very high durability to possible degradation related to chemical cases.
- High adaptability to different kind of supports.

 Instruction for use

Substrate preparation:
- - The base support surface must be resistant, uniform, smooth, clean, dry and free of foreign bodies.
- In case that the support consist on thermal insulation, boards must be placed staggered and without gaps wider than 1 mm.
- Polyester geotextil Danofelt PY 300, or higher will be used as separation or protection layer.
- DANOPOL FV dimensional stability (≤ 0,09%) allows no perimeter anchorage installation on the horizontal plane for ballasted systems performed with this waterproofing membrane, meeting standard UNE 104416.
- The joint between the fixed profile and the vertical surface must be always sealed with the elastic, rot-proof and non-biodegradable selant ELASTYDAN PU 40 Gris.

Singular Details
- At the vertical perimeter’s connection, membrane must go up the vertical surface at least 20cm above roof’s last layer, or higher, if necessary, to ensure that the upper edge of the membrane remains always above the maximum foreseeable water over the roof.
- Adhesive product GLUE-DAN PVC is recommended to improve aesthetic finishing on the vertical plane.
- To improve overlaps resistance, particularly in green roofs, it is advisable to seal the overlap line using LIQUID DANOPOL, in the same color, applied with a construction bottle.
- When the parapet’s height does not exceed 20 cm, or there is no perimeter parapet, connection between horizontal membrane and parapet or slab edge can be achieved using PVC laminated profile C (angle) .
- This profile shall be fixed to the horizontal wall by its wing, which will have one width greater than 6 cm, using anchors at a distance less than 25 cm from each other. The membrane must be welded to the laminated profile, hiding all the screw heads

Waterproofing membrane placement:
The membrane will be loose-laid placed over the support and perpendicular to the roof maximum slope line, from the lowest point to the top of the roof. Anchorage to the structural support will be done by slab, gravel or pavement ballasting.
-The watertightness between DANOPOL membranes will be achieved through thermoplastic welding with hot air welder, or using chemical agent THF (tetrahydrofuran). The overlaps between membranes must be 5 cm minimum and the welding must be at least 4cm. During the thermoplastic welding, use a silicon pressure roll. After the installation, it is recommendable to use a blunt metal needle (with a 1-3mm head radius), passing it along the union edge, verifying all the connections.
- There should not be more than 3 membranes coinciding in a single point.
- Special attention will be paid to T-Joints (three sheets intersecting at the same point).
- All membrane vertexes will be cut in a curve shape.

 Indications and Important Recommendations

-Incompatible materials in direct contact with DANOPOL FV 1.2 LIGHT GREY waterproofing membrane: Bituminous products, XPS, TPO/FPO, EPS, EPDM, PU. DANOFELT PY300 or higher must be placed between both materiales to avoid chemical incompatibility or smooth any coarse surface.
- Make sure the chemical compatibility of DANOPOL FV 1.2 LIGHT GREY with other materials.
- Weldability and weld quality depends on atmospheric conditions (temperature, humidity), welding conditions (temperature, velocity, pressure, cleanliness) and by the state of the membrane surface (cleanliness, humidity). Therefore must meet the hot air machine for the correct assembling
- Once the surface has been cooled, a strict welding control should be made using a blunt needle.

- This product is part of a waterproofing system, please pay attention to all DANOSA documents and all rules and mandatory law in this regard.
- Special attention should be paid to the implementation of the singular points and special details.

 Handling, Storage and Conservation

- DANOPOL FV 1.2 LIGHT GREY is not toxic or flammable.
- DANOPOL FV 1.2 LIGHT GREY should be stored in a dry place protected from rain, sun, heat and low temperatures. Be kept in its original packaging, horizontal and parallel all the film (never crossed) on a support level and smooth.
- DANOPOL FV 1.2 LIGHT GREY will be used first come to work.
- DANOPOL FV 1.2 LIGHT GREY is easy to cut to adapt the size to work.
- No waterproofing works should be performed when weather conditions may be harmful, particularly when it is snowing or there is snow or ice on the deck when the cover is rain or wet surface moisture> 8% as QAT NTE or strong wind.
- No waterproofing works should be performed when the ambient temperature is less than -5 º C for hot air welding.
- In all cases, be taken into account Health and Safety standards at work, and the rules of good construction practice.
