How are the joint widths and joints colours to be chosen?
The joint widths are generally derived from the difference between the nominal size and the work size, or are specified as recommendations in the filing standards. Recommended joint widths:- Side Length : up to 100mm: approx. 2mm From 100mm to 200mm: approx. 3mm From 200mm to 600mm: approx. 4mm There are no restrictions on the choice of joint colour for tiles. The right choice of joints is also important for non vitreous, as the joint water may lead to the dispersion of colour pigments from the mortar under the glaze, which will subsequently discolour the tile surface.
