What requirements must be met for adhesive mortar mixtures (ready-to-use)?
Resistance to slipping of adhesive mixtures is characterized by the value of displacement under the influence of gravity of facing tiles laid on a vertical or inclined surface. For adhesive mixtures of class T, the displacement value should be no more than 0.5 mm, for mixtures of other classes - no more than 0.7 mm.
The water-holding capacity of adhesive mortar mixtures, ready for use, must be at least 85%
The water-holding capacity of ready-to-use adhesive mortar mixtures must be at least 98%
The average density of adhesive mortar mixtures must exceed 1800 kg/m3
Resistance to slipping of adhesive mixtures is characterized by the value of displacement under the influence of gravity of facing tiles laid on a vertical or inclined surface. For adhesive mixtures, the offset value should be no more than 1.5 mm.
The average density of adhesive mortar mixtures is set by the manufacturer at the request of the consumer
