ANHYDRATE FLOWING SCREED |
|
Walkable Surface |
7 days requires both covering and curing |
24-48hrs after placement no curing required |
|
Surface Finish |
Achieved tolerance of +/- 10mm under a 2mtr straight edge |
Achieved tolerance of +/- 5mm under a 2 mtr straight edge |
|
Performance |
Prone to shrinkage, cracking and curling. |
Very low shrinkage and cracking. Will not curl. |
|
Strength (28 days) |
Compressive: 10-20n/mm3 Flexural: 4-8 nmm3 8 -28 days to reach 90% strength |
Compressive: 30n/mm3 Flexural: 8n/mm3 7 days to reach 90% strength |
|
Drying Time |
1mm per day up to 40mm thickness ½ mm per day after thereafter 75mm takes significantly longer to dry Can’t be forced dried |
1mm per day up to 40mm thickness ½mm per day thereafter. Can be force dried using heater and de humidifier. ufh can be commissioned after 7 days |
|
Quality Control |
Often mixed by and placed by hand. Labour intensive and inconsistent |
Produced to fully verifiable industry standards |
|
Conductivity |
1.1w/m2k |
2.2w/m2k - faster heat reaction time 10% saving on running cost |
