Why Klassic
Modern tiles require a polymer-modified tile adhesive, not traditional sand-cement mortar.
Limitations of traditional screed installation
Modern tiles have low porosity
The low porosity of vitrified tile provides limited mechanical key for plain cement mortar, increasing the need for a purpose-formulated adhesive.
Plain cement mortar loses moisture rapidly
Without performance additives, cement mortar can lose moisture too quickly, increasing the risk of shrinkage and tile debonding.
Traditional screed beds can create concealed voids
Sand-cement screed installation can leave voids beneath the tile, reducing support and increasing the risk of cracking under load.
Advantages of a Klassic adhesive bed
Resistance to vertical slip
Tiles remain in position during the adhesive’s open time, supporting accurate installation on vertical surfaces.
Effective water retention
The formulation retains the moisture required for proper curing, supporting bond development on cementitious substrates.
Factory-engineered formulation
Graded sand, cement, polymers, and performance additives are precisely formulated for the required tile and substrate class.
Improved cohesion and workability
Polymer modification supports consistent trowel application, broad coverage, and a reduced risk of cracking or debonding.
Easy to apply
