Subfloor preparation The key to a durable and complaint-free floor

Subfloor preparation is a crucial step when laying floor coverings. Regardless of whether it is screed, concrete or other substrates, the floor should be dust-free, level and free of old layers. Thorough preparation of the subfloor ensures that the floor covering is not only visually appealing, but also durable and resistant. Wolff offers a wide range of high-quality machines and tools for this essential phase of floor laying.

Steps for subfloor preparation

  1. Evaluate the substrate: The first phase of subfloor preparation is to assess the condition of the existing floor. It is important to recognise any unevenness, cracks or separation layers.
  2. Removal: Now it's time to remove the old layers. Mill off any adhesive residue or levelling compound. The more carefully residues are removed, the better the end result. This step is mainly used for renovating old buildings.  However, there may also be separating layers on new screeds that need to be removed.  
  3. Cleaning: Clean the floor thoroughly before the actual preparation. A cleaning sanding removes the last irregularities, dirt or old coatings (in the case of renovations) from the surface. Finally, Wolff industrial vacuum cleaners are ideal for removing all dust and dirt.
  4. Smoothing and levelling: Wolff grinding and milling machines can be used to smooth the floor and remove any unevenness. These machines are essential for creating a level surface for the subsequent floor installation.
  5. Priming and levelling: Levelling tools and agitators from Wolff make it possible to prime the floor and apply levelling compound evenly. This gives you an optimum surface for laying the floor.



Thorough inspection: Before you start, inspect the floor carefully. This will ensure that you identify all problem areas.

Correct tool selection: Choose the appropriate machines and tools for the specific soil type and specific requirements of your subfloor preparation.
