Siena Premium Set 550 is a premium dry-set mortar manufactured with a mixture of Portland cement, graded aggregates and other proprietary additives to produce a high quality mortar that does not require soaking of tiles to give higher bond strength, greater open time and coverage than standard dry-set mortars. Siena Premium Set 550 is available in either white or gray color and complies with the requirements of ANSI A118.1. If used in conjunction with Siena Acrylic Admix AX300, it will also comply with the requirements of ANSI A118.4.
