Application
Application 1: 
Application of adhesive to bases for the installation of ceramic or plastic tile interior wall finishes, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9].

Intent
Intent 1: 
To limit the probability of the inadequate adhesion of tiles to the substrate, which could lead to an inability to resist expected impact, gravity or lateral loads, which could lead to the dislodgement of tiles, which could lead to compromised protection for moisture-vulnerable substrates.
This is to limit the probability of the deterioration of the substrate, which could lead to:
  • where the substrate for the tile contributes to the required bracing or lateral support for studs, the buckling or racking of walls, which could lead to structural failure, or
  • where the substrate for the tile supports required environmental separation elements, the excessive deformation, displacement or failure of such elements, which could lead to further deterioration, which could lead to further compromised structural integrity.
This is to limit the probability of:
  • the space being unsuitable for its intended use,
  • compromised operation of doors or windows, or
  • damage to the building.
