Troweled mortar. A troweled epoxy mortar is a typical choice for flooring with chemical, abrasion, and impact requirements. Hand-troweled like concrete, mortar is applied at thicknesses ranging from 3/16 inch to 3/8 inch. It is suitable for heavy-duty environments such as commercial kitchens or industrial facilities. Some systems include recycled glass fillers and rapidly renewable soy-based resins to increase texture and to withstand thermal cycling/thermal shock for use in food environments.

Troweled epoxy mortar is also utilized for renovating and replacing damaged floors.

Problems with quarry tile in a bacteriaprone commercial kitchen included cracking, cleaning difficulties, and danger from slipping and tripping. The solution was a poured, hand troweled epoxy mortar floor.

Broadcast systems. Many configurations for moderate to high-performance needs require one or two layers of aggregate between the primer, undercoat, and sealer. In addition to durability, aggregates add texture, color, and static control. Silica sand, colored quartz sand, recycled glass fillers, or other aggregates are broadcast over a wet epoxy primer or undercoat by methods that date back to when farmers cast seeds on newly prepared soil. Today, installers ideally use machines to achieve a regular even spread. The entire floor is coated and broadcast to refusal (meaning that it has enough aggregates in the material to make it appear dry; otherwise wet spots will appear and affect the look and consistency of the texture). Reclaimed broadcast materials should not be reused.
