Terrazzo Floor Thickness
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.
Terrazzo floor thickness. Procedure of laying terrazzo tile flooring 1. Today most of the terrazzo installed is epoxy terrazzo. 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.
It has the greatest range of color choices and is least likely to crack because the epoxy resin increases flexibility. The best thin set system. The terrazzo itself is usually 1 2 to 3 4 inch thick and is placed on a 1 1 2 inch thick bed of mortar. 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.
Due to its thinness it is also light in weight. Monolithic cement terrazzo floor is approx. Polyacrylate is a cement modified acrylate creating higher compressive strength and higher impact resistance than cement. A sand cushion terrazzo floor is the ideal system for a floor where deflection or movement is anticipated.
Polyacrylate also allows for vapor transmission. Dividers at approximately 5 0 on center are still required to help offset any expansion or contraction of the terrazzo finish. 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. Thin set terrazzo systems include epoxy resin or polyacrylate as the matrix.
Thinset terrazzo this is a layer of epoxy resin terrazzo about 3 8 thick poured over a concrete substrate. 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. However due to the thickness of the system a slab depression of 2 5 to 3 is required. A nominal 1 4 or 3 8 thick resin matrix veneer placed upon a level concrete slab.
What is the normal thickness of a terrazzo floor topping. Sizes of terrazzo flooring tiles. Probably the most common terrazzo system available epoxy terrazzo is ideal for any type of residential or commercial building. Installed in the same manner as for regular monolithic terrazzo but at a minimum 3 8 thickness.
