A rapid-setting, Portland cement-based, polymer-modified mortar with MICROTEC® and self-drying technologies, ARDEX X 32™ MICROTEC® Universal Rapid Setting and Drying Thin-to-Thick Bed Mortar is ideal for moisture-sensitive natural stone, marble and granite installations. It will not contribute to staining, discoloration or warping of natural stone tiles. ARDEX X 32 can be used as a thin to thick bed up to 1 1/4” (31.8 mm) thick and is excellent for use with agglomerate and ungauged stones that require various mortar depths. 

Even at a 1 1/4” (31.8 mm) thickness, ARDEX X 32 is ready for grout in just 3 hours, making it ideal for same day interior or exterior fast track installations. ARDEX X 32 can be used over exterior concrete and masonry surfaces and over common interior substrates, including concrete, masonry and exterior-grade plywood.

Priming / Treating the Substrate

Highly absorbent substrates, such as plaster, existing tiles and certain non-porous substrates must be primed or treated as detailed below before proceeding with the tile installation.

Mixing and Application

For one 40 lb. (18 kg) bag of ARDEX X 32, use 5 3/4 - 6 1/2 quarts (5.5 - 6.1 L) of clean water. To mix smaller quantities by hand, use 3.25 parts powder to 1 part water by volume. Pour water in the mixing container first, and then add the ARDEX X 32 while mixing for 2 to 3 minutes. For best results, mix with an ARDEX T-2 Ring Mixing Paddle and 1/2” heavyduty drill (12 mm, min. 650 rpm). If mixing by hand, use a margin trowel and mix vigorously. Just prior to application on the substrate, the mixture should be stirred again to ensure a creamy, smooth, lump-free consistency. For improved adhesion, flexibility, strength and water repellence in specialized installations, add ARDEX E 90 in accordance with the instructions in the ARDEX E 90 technical data sheet, and then follow the mixing instructions above.

Grouting

Tiles can be grouted after 3 hours in accordance with ANSI A 108.10. For moisture-sensitive tiles, use ARDEX WA™ High Performance, 100% Solids Epoxy Grout and Adhesive. For non-moisture-sensitive tiles, use ARDEX FL™ Rapid Set, Flexible, Sanded Grout, ARDEX FH™ Sanded Floor and Wall Grout, ARDEX FG-C™ Unsanded Floor and Wall Grout or ARDEX WA, as appropriate. For soft joints, ARDEX recommends ARDEX SX™ 100% Silicone Sealant for Tile and Stone Applications.
