Tile Glue compatibility

[Georgialmc]

Hi All, I have waterproofed my bathroom with the Bastion primer and Bastion undertile waterproofing membrane what tile glues are most compatible with this membrane system?

Hi @Georgialmc,

Thank you for your question.

You'll note that the Specifications Sheet for Bastion Under Tile Waterproofing Membrane states that -

"When tiling directly over Bastion Under Tile Waterproofing Membrane in internal or external floor areas, polymer-modified cement-based adhesives must be used."

Both Davco 20kg SMP Evo Tile Adhesive and Dunlop 20kg Rubber Modified Tile Adhesive are polymer-modified cement-based adhesives that would be suitable for both wall and floor tiles over your waterproofing membrane.

Let me know what you think and if you have further questions, please don't hesitate to ask.

Jacob
