Ardex X5 Polymer Modified Thin Set Mortar


Ardex X5 is so easy and efficient to use that you will save time and money on every stone veneer, thin brick, and tile job.

Are you tired of mixing your own mortar and the complications that come along with it? Like having to mix too many components, not having enough pot life, or crumbling and making too much of a mess? Are you frustrated when you aren’t able to move stone once its set? Do you want to speed up installation time and save money? Well, Ardex X5 will help solve all your problems.

Ardex X5 is a unique flexible stone mortar that is taking tile and stone installation to the next level. This highly versatile, polymer modified mortar has an easy to apply creamy consistency that is perfect for setting all sizes of porcelain, ceramic, quarry, mosaic and most natural stone tile on both exterior and interior surfaces. You can create the natural concrete look without the heaviness of a thick mortar bed and best of all, anyone can use ARDEX X5 with great success!


Ardex X5 Key Features:

  • Flexible

  • Single Component

  • Sag resistant

  • Easy to mix and apply

  • Water and frost resistant

  • 3 hour pot life

  • 15-20 minutes of working time to adjust stone after installation

  • 10 year Warranty

Did you know? Unlike traditional mortars, Ardex X5 can be used in cold temperature! If you are working on an outside job and the temperature drops, you can leave your work and return to it the next day. Ardex X5 will go into “hibernation mode” when the weather drops below a certain temperature and will not be disrupted. Rain will not affect Ardex X5 either! Simply wipe off any excess Ardex and return to the job when it is no longer raining.

To Apply: Cover the substrate with Ardex X5 using a ¼” notch trowel. If you have irregular shaped stone that needs adjusting then you can apply ¼” of Ardex to the back of the stone and then apply to the wall. You may opt to apply a scratch coat or netting to the wall prior to
