Selection priorities

There are key factors that influence correct product selection. These can often be grouped as below with some examples of considerations needed:


  • What is the substrate onto which tiles are to be fixed?
  • Is it flat - or does it need levelling/smoothing?


  • Is it indoors or outdoors?
  • Is it a domestic installation - or a public/communal place?
  • Will it be a dry place, or intermittently wet - or regularly wet?

Service conditions

  • What is the tiled area to be used for?
  • Is there a power shower - or total immersion?
  • Will it be subject to movement/vibration and/or heavy trafficking?
  • Are there any special service requirements applicable (EXAMPLES: extra hygiene/ sterile conditions/protection from bacteria/chemical resistance)?

Tile type and size

  • Are tiles porous - or fully-glazed/vitrified?
  • Are they light-coloured/ translucent or natural stone?
  • Is the tile material vulnerable to staining by grouting?
  • Are the tiles subject to water-staining?
  • Are they large format tiles? (Adhesive may take longer to set fully on some substrates).
  • What is the tile weight per m2? (Is the substrate able to carry that weight?)

Guidance on all of these considerations can be found in the BAL professional fixing guides; "product selection" and its companion "sitework guidance" and can be downloaded below.
