Terrazzo Floor Thickness

Polyacrylate also allows for vapor transmission.

Terrazzo floor thickness.

A nominal 1 4 or 3 8 thick resin matrix veneer placed upon a level concrete slab. Thickness 3 8 or 1 4 1 4 system should be used only with simple and open strip patterns such as school and pharmaceutical projects and where there is a close tolerance for flatness. Today most of the terrazzo installed is epoxy terrazzo. However due to the thickness of the system a slab depression of 2 5 to 3 is required.

Thick and consists of a cement matrix and marble aggregate topping mix that is applied directly to the concrete slab using a bonding agent between the cement terrazzo and the concrete slab. Dividers at approximately 5 0 on center are still required to help offset any expansion or contraction of the terrazzo finish. Monolithic cement terrazzo floor is approx. Thickness ranges from 1 4 inch to 3 8 making it one of the thinnest floor materials around.

Thin set terrazzo systems include epoxy resin or polyacrylate as the matrix. Sizes of terrazzo flooring tiles.

A sand cushion terrazzo floor is the ideal system for a floor where deflection or movement is anticipated.

It is the lightest type of terrazzo in weight and can be installed over existing concrete or a plywood subfloor. It literally is the best thin set system. This mortar bed may rest directly on the base slab but frequently it is separated from it by a 1 4 inch cushion of sand or a layer of asphalt paper.

The advantages of this material over cementitious terrazzo include a wider selection of colors 1 4 to 3 8 inch 6 4 to 9 5 mm installation thickness lighter weight faster installation impermeable finish higher strength and less susceptibility to cracking. Thinset terrazzo this is a layer of epoxy resin terrazzo about 3 8 thick poured over a concrete substrate.

Procedure of laying terrazzo tile flooring 1. The best thin set system. Also can be specified with glass synthetic or granite aggregates in lieu of marble to provide brilliant colors or chemical resistance. The finished thickness of the upper layer of the terrazzo tile shall not be less than 5 mm for the size of marble chips from the smallest up to 6 mm and the same wise 5 mm for marble chips smallest to 12mm and 6mm for marble chips smallest to 20mm.
