1. Apply a line of bathroom silicone to the underside of the basin in the following locations:
    1. A circle around the waste hole.
    2. Around the perimeter of the basin approximately 2-3cm from the edge.
  2. Apply 4 dots of silicone to the benchtop around the waste hole.
  3. Press the basin down onto the benchtop lining the waste holes up.
  4. Apply a line of silicone between the basin and the benchtop.
  5. Spray the silicone with soapy water and use a silicone scraping tool or your finger to smooth out and remove excess silicone.
  6. Spray or wipe soapy water on the inside of the basin around the waste hole, making sure none goes into the waste hole area. This will stop excess silicone from sticking to the basin.
  7. Apply a thick line of silicone around the waste hole and place the basin waste evenly into position.
  8. Apply more soapy water over the basin waste if desired to stop silicone from sticking to it.
  9. Apply a thin layer of clear silicone over the join between the basin and waste.
  10. Use a silicone scraping tool or soft cloth to wipe away all excess.
  11. Leave for 24 hours for the silicone to completely dry.
  12. Check to ensure that water flows properly down the waste hole.
  13. Apply a new layer of wax following the normal waxing instructions.
