  2. 2nd coat consumption 0.8 - 1 kg/m2 approx.
  • Application:
  1. Sewage treatment facilities including concrete tanks, digestors, clarifiers etc...
  2. Water treatment facilities.

  4. Terraces and balconies.
  5. Bridges & Sea walls.
  6. Retaining walls & for sealing “hairline” cracks in concrete structures not subject to movement surfaces.
  7. Swimming pools and waterproofing of drinking water tanks and reservoirs.
  • Usage:
  1. The consistency of the mix can be altered by reducing the amount of component (A) (liquid) to be used. Under normal circumstances, when the full quantities of both components are mixed together, a slurry consistency will result.
  2. For a trawlable consistency use only 90% of component (A) (approx. 4.5 kg) Mix in a clean container by slowly adding the powder component to the liquid component and stirring with slow speed mixer.
  3. While the surface is still damp (no standing water) apply the first coat and leave to harden (2-6 hours). For slurry consistency, apply with a hard-plastic bristled brush or broom.
  4. For trawlable mortars, use a notched trowel. After the second coat has been applied, finish by rubbing down with a soft dry sponge. After application of the second coat, finish SikaTop  Seal-107 by rubbing down with a soft dry sponge.
  5. In case of a third coat, scratch the surface of the second coat with the edge of the trowel to provide a mechanical key.
  6. As Balcony Waterproofing Layer Substrate must be SSD with no standing water at time of application. Apply a thick layer of SikaTop Seal-107 over the entire balcony.
  7. While the material is still wet apply a non-alkaline, woven fiberglass mesh to reinforce the 107 layer along static hairline cracks, wall to slab transitions and patched areas.
  8. Using trowels remove any wrinkles in the mesh by forcing down into the SikaTop Seal-107.
  9. Ensure the mesh is completely embedded and covered with SikaTop Seal-107. If any areas are not covered apply additional SikaTop Seal-107 over top of mesh to cover. Trowel to a smooth uniform finish.
  10. Allow curing so that surface can take light foot traffic without harming the coating.
  11. In case of needed plaster layer over SikaTop Seal-107, broadcasting rough sand is recommended to apply as bonding agent.
