Understand the purpose of floor screeding

Before you begin applying floor screeding, it is essential to understand why you need it for your specific flooring. Screeding helps to level and smooth a surface, making it suitable for installing floor finishes such as tiles, carpet, wood etc. By knowing the purpose, you can determine the best screeding method and materials you will need for your desired finish.

Choose the right materials

Selecting the appropriate materials for your undertaking is contingent on several aspects. When implementing underfloor heating, it’s crucial to opt for a screed compatible with this system. Additionally, you must take into account the subfloor, insulation necessities, and the level of foot traffic the floor will encounter. Being well-informed about these factors will assist you in determining the optimal screed approach and materials for your project.

Prepare the substrate

Achieving a flawless finish without complications necessitates proper groundwork. Firstly, grind the concrete to reveal the aggregates beneath. Then you will need to confirm that the foundation is clean, free of any debris and structurally sound prior to applying the screed. Neglecting these steps may result in an irregular surface or cracked screed. If you are screeding directly onto the concrete without any separating layers, you will need to prime the surface to ensure the product adheres well to the subfloor.

Use guides and levelling equipment

Use straightedges, trowels, laser levels or tripods to establish a level reference. This ensures that the screed will be applied evenly and result in a smooth, flat surface.

Install a damp proof membrane (DPM)

A DPM prevents moisture from seeping into the screed layer, which can cause dampness, mold, or structural damage. Lay the DPM on the substrate before screeding to create a moisture barrier.

Set the appropriate screed thickness

Depending on the type of screed and floor finishes, the required screed thickness may vary. Ensure the correct thickness is applied to prevent cracking or unevenness.

Mix the screed correctly

Follow the manufacturer’s guide instructions when mixing the screed material to ensure the desired consistency and performance. Poorly mixed screed can result in a weak or uneven surface.

Control the temperature and humidity

During the application and curing process, you will need to control the temperature and humidity levels during installation as it can affect the performance and drying time of screed. Avoid exposing the surface to strong drafts and direct sunlight during the drying process, as this can cause the product to dry too quickly and result in cracking.

Allow for proper curing

Allow the screed to cure according to the manufacturer’s guidelines, avoid rushing the process, as this can lead to structural problems or surface defects.

Once the screed is fully cured, check for levelness and smoothness. If required, sand any high spots, or fill in low areas with additional screed material.
