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.
Main parameters
- Mixing ratio (water/dry mix): approx. 0.07÷0.11 l / 1 kg
- Min./max. screed thickness: 10 mm / 80 mm
- Pot life: min. 30 minutes
- Foot traffic: after approx. 12 hours
