Plastically supple laying mortar, the middle bed mortar is only distributed with a sufficiently large notched trowel (middle bed trowel). Low shrinkage, even with large mortar bed thicknesses (up to 4 cm), no shrinkage tensions arise between PCI Carrament and the natural stone slab. Sets quickly, reduces moisture penetration of the installation material during processing and thus prevents efflorescence. Hardens quickly, after approx. Accessible and accessible after 6 hours and after approx. Fully resilient for 1 day. With PCI Carrament white, the adhesive bed does not show through on white marble when laid using the combined method (buttering-floating). On stairs and house bases, in the living area, on electric underfloor heating, heated screeds, balconies and terraces, in halls.
