Newton 906 Lime Inhibitor



  • Concrete floors newer than 12 months:
  • The whole of the concrete slab or raft as well as the recess formed ready for Newton Basedrain or Floordrain Drainage Conduit.
  • Concrete floors older than 12 months:
  • The recess cut into the concrete ready for Newton Basedrain or Floordrain Drainage Conduit as well as 200 mm either side of floor construction or movement joints.


  • 200 mm up the wall from the floor, or where a ‘kicker’ has been formed to a concrete wall, apply from the floor up to 200 mm above the kicker.
  • Underpinned properties require application to 200 mm either side of the joints. Dry-packed areas should be sealed with a cement-based tanking product and then the tanking treated with Newton Lime Inhibitor.


Newton 906 Lime Inhibitor is applied to concrete surfaces prior to the installation of a Newton System 500 cavity drain membrane waterproofing system to prevent the ‘leaching’ of free lime from the concrete. Primarily designed to be used on new concrete structures, Newton Lime Inhibitor should also be used a treatment to cut recesses to existing concrete slabs.

Features and benefits:

  • Solvent and caustic free.
  • Easy to use and handle.
  • Non-hazardous (on dilution).
  • Compatible with alkaline substrates.
  • Long term durability.
