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
