 Instruction for use

Preparation of the support:
Once the waterproofing is done, the roof should be smooth, uniform and clean.
Danolosa application:
- It is applied without any gripping material, deposited with care, preferably over a geotextile antipunching layer covering the waterproofing or directly on it, lying on the insulation face.
- Slabs will be placed without any expansion joint.
- On hipper ends and valleys the slab should be accordingly cut using a water-cooled low r.p.m. radial machine.
- A small space (3-5 mm) must exist, to allow dilatations coming from, for example, skylights, etc…
- It should be carried on pallets.
- Not considered as dangerous goods for transport.

 Indications and Important Recommendations

- The use of Danolosa over supports is restricted to square head supports (min. 200 mm) Danoplot type.
- For the cutting of the Danolosa, it is recommended to use a water-cooled low r.p.m. radial machine, type DU-200-L.
- It is not necessary to cover the joints.
- In the case of a synthetic waterproofing system , it is necessary to use a 300 gr./m² polyester geotextile between the membrane and the insulating slab.
- No hammers should be used for levelling or fitting the pieces.
- Before applying the product it is recommended to test the tightness of the waterproofing.
- This product is part of a waterproofing system, so we should take into account the systems and information contained in the manual of Danosa Solutions.
- Roof regulations must be respected.
- Due to possible variations in the tone of the raw materials, the tones between tiles of the same colour can also vary.
- The apparition of portlantita efflorescences on porous concrete, characterized by changing the colour of the tile, does not mean the decline of its performance. Variations in tone in the raw materials of porous concrete may also vary the tone between tiles of the same colour.

 Handling, Storage and Conservation

- The pallets must be handled with stacker or forklift.
- It is recommended a separation between the forklift nails of 80 cm.
- Due to the nature of the product Danolosa, the pallets must be moved carefully, paying attention to potential bumps, irregularities in the firm, and so on.
- The product will be placed with care so as to prevent any shock that may deteriorate its quality.
- When the product is mechanically processed, propellant gas can be released.
- When the product is overheated, monomers or other degradation products can be released.
- The cutting machines should be placed on a ventilated room.
- Keep away from flames or heat sources.
- Keep in ventilated areas, preferably fitted with fire-fighting systems, as they may release traces of ethanol from the production process.
