MULTISET 917 is the economical polymer modified dry-set mortar designed for the bonding of all types of tiles.
It may be used for either walls or floors for both interior and exterior applications where a liquid latex modified mortar is recommended. MULTISET 917 is a blend of Portland cement, sand and special dry latex additives that significantly improve bond strength and freeze-thaw stability - performance characteristics typically available only through the addition of liquid latex additives to dry-set mortar.
Spread mortar with flat side of trowel to key into substrate; then, apply additional mortar to a depth sufficient to be notch with a suitable trowel that will leave only enough mortar to give 100% contact with back of tile and a subsequent mortar bed of 3/32" to 3/16" (2.4 to 5 mm).
With high lug tiles, “back buttering” may be required to ensure 100% coverage to back of tiles. During the setting of tile, it is advisable to occasionally remove a tile to be sure mortar has not skinned over and sufficient transfer is being made. It is also required that tiles be embedded to obtain good transfer of mortar to tile and for proper alignment.
Do not adjust tiles in mortar after they have been set past 20 minutes.
NOTE: As a practical test, it is recommended that 3 or more separate 12 " square (.3 m2) areas of tile be bonded to the properly prepared surface with the actual tile and bonding material that will be used on
the finished installation. These should be allowed to cure for 3 to 7 days and then removed with a hammer and chisel. At this point, one can determine if adequate bond has been obtained or if a problem exists.
