Best membrane!
I’m very happy with the ARDEX FLEXBONE membrane. Having worked with Schluter Ditra before, I can confidently say that ARDEX is much easier to work with. It’s more flexible, lays flat without any need for stapling, and for the price, you get almost twice the coverage compared to Schluter. Great product!Best regards,MaxI’m very happy with the ARDEX FLEXBONE membrane. Having worked with Schluter Ditra before, I can confidently say that ARDEX is much easier to work with.
