SELF-DAN AL PRO
Self-adhesive SBS elastomeric, easy peel foil faced AVCL.
Product variations:

Innovative Self-Adhesive SBS reinforced bitumen Air and Vapor Control Layer (AVCL).
It consists of a self-adhesive low-thickness bituminous compound reinforced by an external aluminium composite film that forms a barrier against vapour and gases. The aluminium reinforcement provides excellent resistance to puncture and effects of work site foot traffic.
Available in 1, 00 or 1,50 mm thickness.

- Upper Surface: Aluminium foil
- Lower Surface: Removable protective film
Advantages & Benefits
- Modified with SBS polymers, it achieves much higher performance in behavior at high and low temperatures, elasticity and resistance to aging, which leads to improved durability of the membrane .
- Self-Adhesive, Flame-Free application.
- Outstanding Adhesion
- Easy to install.
- Allows for adaptation to any type of geometry.
- Adapts to the substrate geometry with ease.
Instruction for Use
Instructions:
Substrate should be dry and clean from grease, dirt, debris or any other contaminants.
Where applicable, prime surface with the specified bitumen primer in accordance with danosa uk instructions and allow to dry.
Where falls apply, membrane rolls should be rolled up the slope so that waterdrains over and not into membrane overlaps.
For field applications:
Substrate should be dry and clean from grease, dirt, debris or any other contaminants.
Where applicable, prime surface with the specified bitumen primer in accordance with danosa uk instructions and allow to dry.
Where falls apply, membrane rolls should be rolled up the slope so that waterdrains over and not into membrane overlaps.
For field applications:
- Roll the membrane into position, allowing for 80 mm side overlaps and 150mm head overlaps and cut to length. All overlaps and cross joint should be staggered by a minimum of 300mm.
- Roll back the membrane for a portion of the length (approximately 50%).
- Cut across the removeable protective film underside, and peel the film off.
- Peel the leading edge of the film up and tuck it under the roll to enable the release of the remainder when unrolling.
- Roll the membrane forward, applying even pressure downwards and outwards, avoiding trapping pockets of air.
- Roll back the remaining portion of the membrane to the leading edge ofthe release film.
- On completion, use a soft broom or roller to apply pressure over the total area, ensuring all overlaps are fully sealed.
- Place the membrane into position and cut to length ensuring all overlaps and cross joints are staggered by a minimum of 300mm .
- Remove protective film from rear of the membrane.
- Apply pressure and consolidate the bond to the substrate, ensuring all overlaps are fully sealed
Indications and Important Recommendations
- In case of refurbishment, chemical incompatibilities with old waterproofing systems consisting of PVC membranes, modified tar-based mastics or any other, shall be taken into account, and it may be necessary to remove them completely or to use suitable separating layers.
- If it is necessary to adhere to metallic or slightly porous elements, a bituminous primer (IMPRIDAN 100) must be applied to the entire surface to be bonded beforehand.
- Not suitable on flat roofs as permanent waterproofing layer.
- During cold weather, the substrate, if uncombustible, can be heated with the torch or other means.
- This product may form part of a waterproofing system, so all the documents referred to in the Danosa Solutions Manual must be taken into account, as well as all the regulations and legislation that must be complied with in this respect.
- Exposure to the sun can make it difficult to remove the release film. The temperature of the membrane during installation must not exceed 50ºC.
- For ease of installation, it is recommended to cut the rolls into smaller, more manageable dimensions.
- Polyurethane foam shall not be sprayed directly on top of the waterproofing without the use of a suitable separating layer (geotextiles, mortar layers, polyethylene film, etc).
- The use of a roller is recommended to apply more pressure on the tape and improve adhesion.
- It is recommended to protect after installation.
- On porous or not very homogeneous substrates, a bituminous primer must be applied before application.
- NOTE: For more information on the Danosa systems in which this product is used, please see the document "Waterproofing Solutions".
