Properties
Properties
ATLAS POSTAR 20 is produced as a dry mixture of Portland cement, quartz fillers and modifying additives.
Thick-plastic – the working consistency of the mortar allows easy spreading of the mix, blending in and achieving an even surface (horizontal or with a slope).
Compressive strength: ≥ 20.0 N/mm².
Flexural strength:4.0 N/mm².
It has very low linear shrinkage – minimal linear changes in the screed during drying (on the order of 0.6 mm/mb) reduce the possibility of cracking.
