Installation of cotto

Cotto is an elaborate production process from fired clay material with a quite particular charm. Particular care and practical knowledge is needed to install. Installation on damp screeds can quickly lead to effloresence. In order to keep drying times short, a thin or medium bed adhesive with rapid crystalline water binding technology should be used. Before grouting, it is recommended to impregnate the dry tiles in order to ease the wash-off process during grouting. Once hardened the tiles must be carefully acid washed. This is still necessary with a cleanly washed surface to remove the tiles own lime. The tiled finish must then thoroughly dry out before the final treatment with cotto wax or oil is applied.
