SAND CUSHION TERRAZZO
Description:
A cement matrix topping underbed with wire reinforcing, isolation sheet, and sand layer system for interior floor use. This is the best cement system.
Advantages:
Due to the underbed's depth, wire mesh reinforcing, isolation sheeting and sand layer it will absorb minor substrate defects and prevent mirroring to the surface.
Thickness:
2.5" to 3" including a .5" terrazzo topping.
Weight:
25-30 lbs. PSF.
Dividers:
The position of divider strips is essential to performance, serving a dual function: a control for anticipated contraction and an aesthetic enhancement in separating colors. 5 feet or less on centers. Architects should design structural inset expansion plates between areas where major movement is anticipated.
Note: The standard finish on terrazzo is an 80 grit carborundum polish. When used in conjunction with a U/L listed "slip resistant" sealer this provides a 0.6 anti-slip coefficient of friction. Higher polish grits that tend to deepen and darken the aggregates are available.
