How to Prepare Your Floor for Screeding?

Floor screeding is a vital step in creating a durable and even surface for your flooring. Whether you’re installing safety flooring in a commercial setting or preparing a domestic property for underfloor heating, proper preparation ensures the best results. At E Berry Floor Screeds, based in Cannock, we have over 20 years of experience in floor screeding and floor levelling for both commercial and domestic clients. Here’s our expert guide on preparing your floor for screeding.

Why Floor Preparation is Important

Preparation is key to achieving a long-lasting and smooth screeded surface. A poorly prepared floor can result in uneven screeds, cracks, or weak spots, compromising the overall integrity of your concrete floors. Proper preparation ensures that the screed bonds effectively, creating a reliable foundation for further flooring layers.

Step 1: Clean the Surface

Remove Debris and Dust

Before laying a screed, the surface must be completely clean. Remove any dirt, debris, or dust, as these can weaken the bond between the screed and the substrate. For concrete floors, ensure that any loose material is cleared, and oil or grease stains are thoroughly cleaned.

Repair Cracks and Damage

Inspect the substrate for cracks, chips, or other damage. Fill any cracks using a suitable filler and ensure the surface is level. A smooth and stable base is essential for effective floor levelling.

Step 2: Assess the Substrate

Ensure Structural Integrity

The substrate must be strong enough to support the screed and any additional load from furniture, machinery, or foot traffic. If your project involves underfloor heating, ensure that the substrate can accommodate the heating system without compromising its strength.

Apply a Bonding Agent or Membrane

Depending on the type of screed being applied, you may need to use a bonding agent to create a strong bond with the substrate. Alternatively, some projects require a damp-proof membrane to prevent moisture ingress, which is particularly important for safety flooring installations in wet or high-traffic areas.

Step 3: Plan for Services

Install Underfloor Heating Systems

If you’re incorporating underfloor heating, it should be fully installed and tested before the screeding process begins. This ensures that the screed can encapsulate the heating system evenly, providing optimal thermal efficiency.

Allow for Expansion Joints

For larger areas, expansion joints may be required to accommodate movement and prevent cracking. Consult a professional floor screeding specialist to determine the best layout for your project.

Step 4: Measure and Mix Correctly

Calculate the Screed Thickness

The thickness of the screed layer will depend on the type of flooring and the load requirements. E Berry Floor Screeds offers expert advice on determining the appropriate thickness for concrete floors, safety flooring, and more.

Use the Right Mix

Ensure the screed is mixed to the correct ratio of materials. A consistent mix is crucial for achieving a level and durable finish.
