The tiles must be installed using high-performance, elastic cement adhesive. Any uneven points will require excessive grinding, which may spoil the whole floor.
In case of polishing after laying, regardless of the type of material and thickness, it is essential to use the double-spread technique.
Existing expansion joints and laying joints must comply with the reference standards before grunting the joints. The laying joints (grouts) have to be clean, free from dust and have to be sufficiently large to let the grout penetrate deeply and last in time.Joints may be sealed with grunting cements or suitable fillers with color as similar as possible to the color of the terrazzo tile. It is essential to remove sealant residues from the tiles while still fresh.
