FAQ


01 What is the minimum screed thickness?

In general, the screed thickness can vary from 25mm to 200mm. However, this is purely dependent on the type of screed used as self-levelling screed can be applied at a much lower thickness than 25mm. For more detailed information, please visit our different screed services.

02 How long does it take for screed to dry?

Generally, traditional screed dries at 1mm per day up to 40mm and anything thicker than 40mm dries at 0.5mm a day. However, there are additives that allowfull traffic after 7 days.

03 What is screed?

As outlined by the BS EN 13318: Screed is a layer of material laid directly onto a concrete base either bonded, unbounded, floating or over underfloor heating. Traditional screed is a material consisting of cement and sharp-sand at a ratio of 1:4.

04 How to mix screed?

For smaller areas, screed can be mixed by a forced action mixer. For larger areas, screed is mixed via a screed pump.

05 How much screed do I need?

The amount of screed needed depends on the size of the area and the depth of screed that is required. For a quick calculation, please visit our technical page and use the Screed Calculator.

06 Traditional screed vs. flowing screed

Traditional Screed Flowing Screed
A much dryer non-liquid consistency Fast application e.g. Our team applied 600m2 of flowing screed in 5 hours
Can be applied between 25mm and 200mm depending whether it’s bonded, unbonded, floating or modified Ideal for application over underfloor heating systems
Can have full foot traffic after 7 days with the use of additives. Otherwise, it dries at 1mm a day up to 40mm and after that 0.5mm a day Fast drying times – can dry in 7 days
Not as strong as flowing screed however, it can be reinforced using polypropylene fibres (PPF) or a D49 metal mesh Stronger than traditional screed allowing thinner application
Due to thinner thickness, it is lighter in weight
