Substrate preparation
- The support must be healthy, clean, flat, free of paint, crumbling or poorly adhered parts, release agents, etc. and in general without any substance or particle that may prevent correct adherence.
Instruction for Use
2. Set up the Canister DANOBOND as instructed, attaching the appropriate tooling.
3. Mark out the area to be bonded, ensuring the fleece-backed DANOPOL HSF membrane is cut to size and in position.
4. Protect the edge/seam to be welded in order to prevent it becoming contaminated with adhesive.
5. Ensure the Canister DANOBOND is spraying correctly and the spray pattern is 300mm wide.
6. Secure the Canister DANOBOND in a suitable position and apply to the desired substrate. Only the substrate to receive the fleece-backed membrane should be coated.
7. Apply a minimum of two coats of adhesive to the desired substrate, ensuring a two meter pass takes at least 10 seconds.
8. Walk backwards ensuring an even coat of adhesive is applied.
9. Allow the solvents to evaporate for a minimum of 5 minutes at 20°C. N.B: This time will vary depending on climatic conditions.
10. Roll the fleece-backed DANOPOL HSF membrane into the adhesive layer.
11. Consolidate the bond with either a suitable broom or 20kg water-filled roller, removing any air entrapment.
Canister Set-up Guide:
1. Remove the black cap from the canister valve.
2. Attach the braided-hose to the canister valve, using the small nut (image 1). Tighten with a spanner.
3. Attach the other end of the braided-hose to the gun-applicator using the large nut (image 2). Tighten with a spanner.
4. Fully open the valve on the canister.
5. Pull the trigger on the gun-applicator to apply the adhesive.
6. Adjust the bead width by turning the black valve on the gun-applicator anti-clockwise until you have a bead width of approximately 20-40mm (image 3).
Important Note: Set-up your DANOBOND canister adhesive correctly before use to ensure the best possible performance and to avoid leakage or system failure.
Indications and Important Recommendations
- In case of new construction and renovation, possible chemical incompatibilities with APP plastomer-modified bitumen sheets shall be taken into account.
- In case of renovation, chemical incompatibilities with old waterproofing consisting of flexible PVC sheets, 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 (geotextiles, mortar layer, polyethylene film, etc).
- If it is necessary to adhere to metallic or slightly porous elements, a bituminous primer (IMPRIDAN 100) shall be applied to the entire surface to be welded beforehand.
- 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.
- NOTE: For more information on the Danosa systems in which this product is used, please see the document "Waterproofing Solutions".
- Do not use as a top sheet on green roofs.
- Possible incompatibility between thermal insulation and waterproofing shall be checked.
- Special attention must be paid to the execution of the singular points, such as parapets (meetings with vertical and emergent elements), drains, expansion joints, etc.
- 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).
- If expansion that could affect the sheet is expected, a geotextile separating layer (Danofelt PY 200) shall be used between the sheet and the extruded polystyrene insulation panels, so that each product expands independently.
Maintenance Recommendations
- Maintenance requirements for Danosa Roofing Products The following maintenance checks must be adhered to: - A general examination on the condition of the waterproofing and surrounding roof components. - An inspection of all functional roofing elements including skylights, outlets, upstands, penetrations and any other visible roofing components. - Clean outlets, drains, gutters and remove any debris from the roof. - Periodic removal of mildew, moss, herbs or any other kind of vegetation that has been accumulation on the waterproofing. - Periodic removal of possible sediments accumulated on the deck (silt, sledges, slate granules, etc) by occasional water accumulation. - Periodic removal of debris and small objects that may have accumulated on the roof. - Ensure surrounding structural elements are sound such as eaves, flashings, slate tiles and brickwork. - Ensure that the waterproofing is in good condition and there are no blisters, damage or separation. - Review the condition of the waterproofing (adherence to upstands, condition of overlaps, visual appearance, etc) and repair the defects observed. These operations must be carried out twice a year, preferably at the beginning of spring or autumn and must be increased in case of decks or valleys with zero falls. It is also necessary to perform additional maintenance depending on the type of roof, location and proximity of roofs to areas with trees or in areas with high levels of pollution.
