Floor Screeding Perth

Bonded Screeds

A bonded floor screed is when a screed is bonded to a concrete substrate by using a slurry of cement, adhesives and additives, this type of screed is best between the thickness of 15mm to 50mm and is classed as a thin screed type, which is the main standard screed used in Western Australian wet area situations including bathroom screeds, laundry screeds, toilet screeds and even main floor screeds. The main advantage of using an bonded floor screed is strength.

Unbonded Screeds

What are unbonded screeds? Unbonded screeds are not directly bonded to a substrate, and they are typically applied/ bonded to a damp-proof membrane making the screed separate from the base. This type of screed is best when it has a thickness greater than 50mm, but it can also be applied thinner if additives are used in the screed mix. The main advantage of using an unbonded floor screed is that it minimises the risk of shrinkage, which can lead to cracking.

Acoustic Underlay / Floating Screeds  

A Floating screed is similar to an unbonded screed but generally laid on a layer of insulation. They are commonly used in situations where underfloor heating is being used and or for situations where acoustic insulation is used. A floating screed requires a minimum thickness of 50mm in residential and 75mm in commercial applications. The main advantage of using an acoustic screed underlay is eliminating the impact sound noise in homes or offices.
