Questions & Answers
2 questions

I'm applying 3" x 6" ceramic tiles as a back splash in the kitchen and was given Ardex 5X as the adhesive:

1. How thick should the Ardex 5X be applied?
2. Is a trial size of 6mm x 5mm adequate?
3. Is a primer needed on a existing painted wall board before using the Ardex 5X?
4. What should the consistency of the Ardex 5X be?

Standard mortar should be applied no greater than 3/16" thick.

You should use a 1/4” x 1/4” x 1/4” (6 x 6 x 6 mm) Sq.-Notch trowel or larger, depending on square foot coverage, when using Ardex X5.

A primer is not required but may be used when working over a painted blacksplash. The surface must be clean and rid of any and all residues for there to be a strong bond.

Mixing until you get a creamy, smooth, lump-free consistency.

Is Ardex X 5 suitable for installing 3X6 glass subway tiles in a shower?

Yes, this product can be used for glass tiles. Please be sure to reference the TCNA for the guidelines regarding installation
