The Master Screed Guide

Floor screeding is a very important factor when upgrading or levelling an existing floor, and can be described as a layer of material (such as sand and cement) applied onto concrete or insulation, so that other materials can be placed on top – meaning that screed is used more commonly as a levelling material and not a binder.

Although it’s possible for floors to not have screed, this will result in substandard flooring, more prone to future issues that are easily avoidable with screed, such as wearing out before its time. Screed has, therefore, a vital role to play, as well as a wide variety of applications and specific terms that refer to its properties.

General Uses of Screed

Screed can be applied as a floating finish over rigid materials, not just as an intermediate layer, and can even be placed on top of underfloor heating, although it needs to be slightly thicker if that’s the case. It can also enclose the underfloor heating pipes. If screed is not laid down properly, it can develop several issues, so it should always be applied to the highest standards. It should also provide enough support to withstand high volumes of traffic – this makes it extremely useful in places like warehouses.

 

Important Jargon

There are several terms that are commonly used when discussing screed, and that usually refer to the characteristics of the screeding itself, such as the curing of the screed, which means the process of laying polythene sheets over the layer of screed to absorb moisture and prevent the surface from drying out too quickly and cracking. The period of time which these polythene sheets need to remain on site is called the curing time, and it is usually around 7 days.

Another term you may have seen in the walk on time of the screed, which basically means that light foot traffic can finally begin. This period usually occurs after 24-48 hours. As for normal foot traffic in the screeded area, this tends to be after 5 to 7 days, to give time for the screed to settle in its entirety and prevent problems.

Screed drying time is how long it requires for the screed to become dry enough to apply the final floor covering, a process that can last for hours or days, depending on the screed. The screed will reach its final strength after a month, approximately, and it’s best to avoid heavy machinery and major activities in the area until this process is finished.

 

Screeding is one of the most important processes during the laying down of a concrete floor, as well as its renovation, as it offers an assortment of applications to ensure your floor is durable and doesn’t sink or crack.
