Roman Sand Mix

ROMAN SAND MIX is a quality blend of graded sand and portland cement. It is used as an overlayment for worn, spalled, or damaged concrete surfaces in applications less than 2 inches thick. Roman Sand Mix is also an excellent bedding mix for laying slate, flagstone, or brick walkways. Roman Sand Mix is designed to exceed the specifications of ASTM C 387

Compressive Strength:
7 day 3,000 psi (21 Mpa)
28 day 5,000 psi (34 Mpa)

Mixing:
One 80 lb. (36.4 kg) bag will require up to 4 quarts (3.7 L) of water. Thoroughly mix the contents of the bag with 3 quarts (2.8 L) of water, adding the remaining water a little at a time if the
mix is too stiff. Adding too much water will weaken the mix and may cause cracking in the surface.

Finishing:
Use a screed or straight edge to level the surface. Allow the surface water to disappear before finishing. Trowel to a smooth finish, but do not overwork the surface. Over-troweling or finishing
the surface too soon can lead to scaling, cracking, or dusting of the surface.

Curing:
Sand Mix cures under proper moisture and temperature conditions. It’s important to keep the surface damp for several days after placement. Methods include misting, applying a curing agent, or placing plastic over the surface. Protect the sand mix from freezing for at least 24 hours after placement.

Coverage:
One 80 lb. bag will yield approximately .60 cubic feet (.016 cu. m). To estimate the number of 80 lb. bags needed for a job, multiply the length x width x depth (all in feet), then divide by .60
