Abstract
An improved terrazzo process for applying terrazzo to an existing concrete surface comprising preparing the concrete surface, applying two layers of a primer agent, applying a terrazzo layer comprising calcium sulfoaluminate (CSA) cement, white milk glass, and one or more of broken mirrored glass and colored glass, cutting the terrazzo layer, applying a concrete densifier such that the concrete densifier penetrates into at least a portion of the concrete substrate, and grinding and polishing the densified terrazzo layer.
Claims20
A method of forming a glass overlay on an existing concrete substrate, the method comprising:
- treating an upper surface of the concrete substrate by physical means;
- filling one or more cracks in the concrete substrate with a first joint filler;
- applying an anti-fracture membrane over the first joint filler;
- applying a first primer layer over the upper surface, the first joint filler, and the anti-fracture membrane;
- applying a second primer layer over the first primer layer;
- seeding the second primer layer with one or more of sand and shot before it hardens to form a seeded primer layer;
- applying a terrazzo layer over the seeded primer layer after it has hardened, the terrazzo layer comprising, by weight, 57% calcium sulfoaluminate (CSA) cement, 29% white milk glass, and 14% of one or more of broken mirrored glass and colored glass;
- forming cuts in the terrazzo layer;
- filling the cuts with a second joint filler;
- performing a grinding process to the terrazzo layer and the second joint filler;
- applying a concrete densifier to the grinded terrazzo layer and the second joint filler, such that the concrete densifier penetrates into at least a portion of the concrete substrate;
- polishing the densified terrazzo layer and second joint filler;
- and
- applying a sealer to the polished terrazzo layer and second joint filler.
