Selecting the right screed is paramount in ensuring that the floor finish is successful and performs to expectation.

The screed layer of a floor is paramount in ensuring that this aspect of a building is aesthetically pleasing and performs as intended. Installing the correct screed for its intended location is essential when aiming to achieve a successful floor finish.

Developers must look at several key considerations before selecting a specific screed and the necessary application method to ensure the specified solution will meet the long-term needs of the site.

One of the first steps will be to analyse the quality of the underlying concrete slabs to ascertain what level of substrate preparation or repair will be required. For example, in the case of bonded screeds, the substrate will need to undergo preparation, typically by means of shot blasting or scrabbling in order to provide a suitable surface for the screed to adhere to.

Once in place, the screed should be able to support not only the finish that is applied on top, but also the everyday, ongoing activity of the site. Inadequate screed layers will inevitably fail when subjected to heavy or intensive workloads, which will spoil the seamless, attractive surface above it.

Being knowledgeable on the specific qualities and properties of each component within the floor is vital to ensuring that all the different sections work together successfully. In addition, sourcing every layer from a single floor supplier is the ideal way to minimise the risk of screed failures. This is because there will be one point of contact who will – at all times – be in the know on all the crucial information regarding all layers’ functioning attributes and how they will work in combination with the materials around it. It will also highlight how each layer will fare when subjected to the site’s daily activity.

Being informed and educated on the type of screed used is by no means a luxury but an absolute necessity when seeking to achieve a functional floor finish.
