I've have seen many attempted to do
terrazzo repairs from the homeowners and guess what? Its looks absolutely horrendous !!! Whats evens worst other company's who are not even in the stone restoration industry attempting to do repairs..... example using : Plaster, Caulking, wood filer? yep wood filler and my favorite concrete with Chattahoochee rocks...
The Pro's @ the NSRA have the knowledge and experience to accommodate your terrazzo and natural stone needs. They will do everything humanly possible to match your aggregate chip as close as possible to original marble aggregate.. As Seen in the Pic below. Leave the repairs to the local experts at NSRA.
