SUBSTRATE QUALITY
- The supporting structure must be of sufficient structural strength to apply all new and existing layers of the roof build-up and the complete roof system must be designed and secured against wind uplift loadings.
- The substrate must be uniform, firm, smooth and free of any sharp protrusion or burrs, clean, dry, free of grease, bitumen, oil, dust and loose surface sand / gravel dressing.
SUBSTRATE PREPARATION
- Use the appropriate preparation equipment to achieve the required substrate quality.
- If dust exists on the surface, it must be completely removed before application of the product by suitable dust extraction equipment.
APPLICATION
Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
Priming
Apply where required to the prepared substrate, Primer-600 at the required consumption.
Alignment
Profiled metal decks:
The sheets must be laid in the direction of the deck ribs. Where side/longitudinal overlap seams occur, they must be fully supported by aligning over the full surface of a top rib.
Overlap seams
Side/longitudinal: 75 mm
End / T-joints: 75 mm
- To achieve effectively sealed overlap seams, they must be rolled down firmly with a pressure roller or by applying pressure.
- If seams are not immediately closed after unrolling the Sarnavap®-5000 E SA FR, all seams must be cleaned with cleaner Sika® Trocal Cleaner L-100, Sarna Cleaner or Sarnafil® T Prep. Allow the cleaners to evaporate completely before bonding.
Profiled metal decks:
- At the end of the rolled sheet, an additional 20 cm wide Sarnavap®-5000 E SA FR support strip must be applied.
- It must be positioned so it aligns perpendicular to the deck rib direction. This provides a continuous support over the ribs allowing the ends of the sheets to be fully bonded.
Bonding
Important: If Sarnavap®-5000 E SA FR is to be applied between +5 °C and +10 °C ambient temperature, heat the seams first using hot-air welding equipment before rolling with a pressure roller. Hot-air welding equipment (e.g. Leister Triac. ) must be set at ~+300 °C with a speed of ~5 m/min.
- Check the alignment of the sheets before bonding.
- Re-align where necessary.
- At one end of the sheet, peel away part of the release liner from the underside and bond this part to the substrate.
- Peel away the release liner sideways from the rest of the Sarnavap®-5000 E SA FR sheet to allow it to bond to the substrate.
- Roll the entire surface area of the applied membrane with a suitable heavy roller.
- At T-joints, the edges of the middle cover sheet must be mitred at 45°.
- After bonding into position, use a small pressure roller to firmly press together, all overlaps including the sheet bevels.
Detailing
- All details such as internal and external corners, upstands, vent pipes, support metalwork etc. must be cut and sealed effectively.
- Sarnavap®-5000 E SA FR must always be attached on the warm side of the thermal insulation.
- The upper edge of the Sarnavap®-5000 E SA FR must be taken up to the top edge / surface of the insulation.
Temporary waterproofing
- If Sarnavap®-5000 E SA FR is to provide a temporary waterproofing layer during construction (up to 4 weeks), a slope of at least 2 % (~1,1°) must be provided to ensure drainage with no standing water.
- Roof drainage lines must be adequately sized.
