Liquid Vs Traditional

Liquid & Flow Screeds
Vs
Conventional Screed
Up to 2000m² per day
PRODUCTIVITY
Up to 150m² per day
24 – 48 hours (weather depending)
TIME UNTIL FLOOR CAN BE WALKED ON
7 days
30 - 40 linear meters
Following building construction joints
JOINTS
Can be laid in small bays between 5 & 7 linear meters
Very low shrinkage
Minimal cracking
Will not curl
PERFORMANCE
Shrinks
Cracks
Curls
Easily achieves SR2 under BS 8204
SURFACE FINISH
Depends on contractor
Curls & cracks at joints
No reinforcement requirement
40mm minimum thickness in commercial buildings
35mm minimum thickness in domestic buildings 
ON INSULATION
65mm minimum thickness
40 days at 40mm
Dependant on site conditions
Can be force dried if under 40 days is required 
Polythene laid directly to substrate, minimal preparation
No reinforcement 
30mm minimum thickness 
UNBONDED FLOOR CONSTRUCTION
D49 or fibre reinforcement 
50mm minimum thickness
Produced under BS EN 13454
QUALITY CONTROL
Often mixed on site by hand with poor quality control
Labour intensive 
Inconsistent quality of materials 
Self compacting
INSTALLATION
Requires thorough compaction, one of the main reasons for failure 
From 40m², liquid flowing screeds are lower in cost
COST
The economies of scale are such that the larger the floor the more expensive conventional screed becomes
