Sand/Grouting Mix

SAND/GROUTING 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. Vita-Crete Sand/Grouting Mix is also an excellent bedding mix for laying slate, flagstone or brick walkways. Use for forming shower bases and under hollow fixtures. Vita-Crete Sand/Grouting Mix is designed to meet or exceed the specifications of ASTM C 387 for high strength mortar.

  • 28 day 5,000 psi (34.5 MPa)


One 80 lb bag (36.2 kg) bag will require up to 4.5 quarts (4.3L) of water. Thoroughly mix the contents of the bag with 3 quarts (2.8L) 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 cause cracking in the surface. Use of an approved bonding adhesive or integral admixture is recommended for patching applications.


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.


Sand/Grouting 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 or wet burlap over the surface. Protect the Sand/Grouting Mix from freezing for at least 24 hours after placement.


One 80 lb. bag will yield approximately .60 cubic feet. To estimate the number of 80 lb. bags needed for a job, multiply the length x width (in feet) x depth (in inches), then divide by 8.
