Version: Jan. 25, 2010 d e B 4 x d i u M M 1 to ™ Sand and Cement Mortar Mix Description Limitations 4 to 1 is a preblended mixture of finely graded sand and Portland cement used for thick-bed mortar installations. 4 to 1 flattens and levels an existing substrate before the installation of tile and stone. • 4 to 1 can be mixed with water for most interior conditions. For better performance or for exterior or heavy-duty wet areas, mix 4 to 1 with Planicrete AC instead of with water.

Apply a cleavage membrane or slip sheet (6 mils [0,15 mm] of polyethylene or 15 lbs. [6,80 kg] of roofing felt) to the substrate. 3. Lay out rolled or self-furred sheets of 2" x 2" (5 x 5 cm) 16-gauge galvanized wire mesh throughout installation. Overlap mesh by 2" (5 cm) and connect using wire ties. 4.
