Floor Screed Floor Preparation

 

 

Please note that it is important that the preparation of the floor prior

to installing flowing floor screed is carried out to the highest standard.  

Please see below for details.

 

 

 

 

 

 

 

 

Water Tight       

• The building must be made be weather tight - the roof and external doors /window openings must be fitted with either final fixtures or clear polythene.

 

Exposed Edges

• Install temporary formwork to exposed edges (eg door openings or level changes)  

 

Clean                   

• Remove all dust, debris and contamination from the floor surface.

 

Insulation:       

• Ensure that all high/low points are removed from the sub-base and that insulation boards are laid flat.
• Insulation boards should be tightly butt jointed with staggered joints.

 

Membrane:                      

• Install a polythene separating membrane to floor (500 guage or similar) join with 50mm tape. Ensuring that all air pockets are removed and are free from punctures and creases.
• Lap joints should be 100mm and where necessary continue the polythene up the face of all wall/floor joints to the full depth of the screed.
• Perimeter isolation strip should be fixed at wall/floor junctions and around any columns, pipework etc

 

Underfloor Heating    

• When used on underfloor heating we recommend using polythene to separate the membrane.
• All heating pipes and cables must be securely fixed down.
• Warm water systems should be filled prior to the application of to reduce the risk of pipes floating when the screed is poured.

 

Minimum Application Thickness:

•  Bonded, 25mm
•  Unbonded, 30mm
•  Floating commercial, 40mm
•  Floating domestic , 35mm
•  Underfloor heating (min cover to pipe),  30mm

 

Please make an allowance for tolerances and any isolated high spots as this will impact on the overall depth and material usage.
