Venetian craftsman of the 15th one C created terrazzo flooring using odd - sized marble fries pass on over from the construction of terraces . Today terrazzo floor is composed of a mixture of aggregates , such as marble , granite , quartz , recycled glass or plastics , embedded in cement or epoxy .

Venetian artificer of the 15th century created terrazzo blow out of the water using odd - sized marble chips left over from the grammatical construction of terraces . Today terrazzo flooring is compose of a premix of aggregates , such as marble , granite , lechatelierite , recycled glass or credit card , embed incement or epoxy . It is used in institutions like hospitals and schools and in commercial building . Its exterior applications include walkway and terrace .

Considerations

Considerations in choosing a terrazzo system include whether the floor is for inner or exterior use , or both ; whether the system needs to be breathable ; whether there are time constraints on installation ; and what variety of aggregates and colour you hope .

Matrix Types

The matrix types for terrazzo flooring are Portland cement , polyacrylate and epoxy glue . Polyacrylate terrazzo is a polymer - modify cement matrix three - 8th inches dense . epoxy glue terrazzo , also known as lean - curing terrazzo , is a 1/4 - in or 3/8 - inch thickness of resin terrazzo .

Characteristics

The sand shock absorber system , for internal employment , is the good cementum - based arrangement , harmonise to the National Terrazzo and Mosaic Association , Inc. web site . A sand layer or closing off membrane come apart terrazzo from substrate with this organisation . The polyacrylate system of rules is 3/8 - inch deep and good for employment in areas where wet vapor transmission do not allow the exercise of non - breathable story , such as epoxy terrazzo . It can be used for internal or exterior applications . Epoxy terrazzo resist many chemical substance wasteweir , making it ideal for science lab or hospital . It is not , however , recommend for exterior use .

Special Conditions

contractor use bind cement system where internal or exterior condition require filling 1 1/4 column inch to 1 3/4 inch recessed depth , plus the 1/2 terrazzo topping , fit in to the National Terrazzo and Mosaic Association website . Another cementum system , the monumental system , is economical and quickly installed for when time and budget are of the essence . However , the arrangement depends on the concrete quality for mat and crack bar .

Interior Use

George Sand shock and epoxy systems are both for ground story or multi - story interior use . Sand shock terrazzo is breathable ; it can reconcile substrate shortcoming ; and it can accommodate the largest aggregative buffalo chip size of it . However , it necessitate a minimal two - inch depression for installation and a lengthy curative sentence . epoxy resin terrazzo can be used over a concrete or Mrs. Henry Wood substratum ; it has greater blueprint flexibility ; and its color reach is straight-out and the colors vibrant . However , its sparseness means that the substrate must have a high languor tolerance and its non - breathability means that slab on level applications require a wet barrier at additional cost . The epoxy ring-binder is more expensive than the cementum ring-binder , but epoxy terrazzo enjoys the monetary value advantages in installation and maintenance , according to the Master Terrazzo Technologies website .
