What is screed used for?
Screed’s main purpose is to level out a concrete subfloor. When dried it creates a smooth and level surface that is great for laying a finishing floor (carpet, tile, etc.). Screed is required when in floor radiant heating is installed (it covers the and protects the heating elements).
Why is screed important?
Laying screed is important because it provides a smooth and even surface to a sub-floor that was designed for durability and not finished characteristics (being smooth and level). In general a floor should not be off by more than 5mm over 3m or a slope of 2%.
Screed Drying Time
The drying time will change depending on the thickness of your screed. Generally foot traffic can resume in 24-48 hours, and closer to 5 days normal use and a month to achieve maximum durability. Additives can be put in the mixture to speed up drying time. Ontario Self Leveling Concrete can customize you screed for the projects requirements.
When can I install a floor on screed?
The concrete will shrink as it dries so it is highly recommended that the screed is fully cured before putting a floor on top of it. Is screed suitable for residential or industrial applications? Screed is very adaptable and can be used in residential, commercial and industrial environments. If the floor is going to be subject to extreme loads then the screed can be specialized to withstand the additional weight
How is screed levelled?

Using a float
A float is a tool that manually scrapes the top layer which makes the desired level. Four level points are measured, and then the float is dragged over the surface creating a level surface.

Self Levelling
Self Levelling screed is much more viscous (flowing/watery). The screed is poured on the subfloor and then gravity does the levelling for us.

Any Climate Factors to Consider?

Screed should usually be installed in dry conditions that are above 3 degrees celsius.

Are all screeds self-levelling?

No. Traditionally a float was used to level but modern screed products are completely self-levelling which is perfect for large areas.

Is screed required for underfloor heating?

Screed is the ideal solution for in floor heating. The screed protects the heating elements and provides great insulation. For the consumer this means more ambient heat, efficiency and meaning longer lasting more economical solution.

Do all concrete floors need screed?

Without screed it is incredibly difficult to level the concrete slab enough to have a nice finished floor on top.
