Holding time after preparation is the maximum period of time during which a freshly prepared mortar mixture (after additional mixing without adding water) retains its technological properties.
A notched trowel is a toothed tool that allows you to create a layer of mortar mixture on the base in the form of grooves of the same thickness.
Open time - the maximum period of time after applying a layer of mortar mixture of a given adhesion strength to the base on the base, during which it is allowed to lay facing tiles on the applied mortar mixture.
Sliding is the displacement under the influence of gravity of tiles or slabs laid on a layer of mortar mixture treated with a notched trowel applied to a vertical or inclined surface.
Adhesion is the ability of a layer of mortar mixture treated with a notched trowel to wet the facing tile.
Pot life is the period of time after mixing the mortar mixture necessary to achieve readiness for installation.
