POLYMER MODIFIED SETTING BED MORTAR

Thick Mortar Setting Bed for Natural and Manufactured Paving Units

Standard (SB-04) and Color (SB-05)

SUPERIOR ADHESION. EXCELLENT DURABILITY.

SPEC MIX® Polymer Modified Setting Bed (PMSB) is specifically engineered as a thick mortar setting bed for natural and manufactured paving units. This product contains a unique blend of polymers and other performance enhancing admixtures, allowing it to meet ANSI and ASTM requirements.

SPEC MIX PMSB can be used as a thick fortified bedding mortar for residential and commercial paving unit applications as well as a joint grouting material between horizontal pavers. It can also be used as a polymer modified dry pack setting bed material in interior and exterior installations allowing light to heavy traffic.

SPEC MIX PMSB is produced under strict manufacturing standards supported by complete quality control measures. A digital printout displaying the proper proportions per batch may be kept as a permanent record.

Each product is 100% dry, preblended in 80 lb. or 3,000 bags, eliminating the need to measure and add liquid admixtures on site which in turn ensures quality control while increasing jobsite productivity—EVERY JOB!
