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.
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.
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.
Pot life is the period of time after mixing the mortar mixture necessary to achieve readiness for installation.
Adhesion is the ability of a layer of mortar mixture treated with a notched trowel to wet the facing tile.
Material on this issue is set out in the GOST R 56387 .
What requirements must be met for adhesive mixtures in a dry state?
The amount of cement in the adhesive mixture must exceed 35% of the mass
The moisture content of adhesive mixtures should not exceed 0.30% by weight
The bulk density of the adhesive mixture should not exceed 1600 kg/m3
The specific effective activity of natural radionuclides of adhesive mixtures should not exceed the limit values established by GOST 30108
The largest grain size of the adhesive mixture should not exceed 0.63 mm.
The content of grains larger than 0.63 mm in the adhesive mixture should not exceed 0.50%
