What type of flooring to choose?
Choosing the right floor screed is one of the most important decisions at any stage of construction or renovation. It is the foundation that determines not only the aesthetics of the floor but, above all, its durability, functionality, and comfort of use. As experts in flooring technologies, we have prepared a comprehensive guide to help you understand the key differences between the most popular solutions and choose the one perfectly suited to your needs.
Which Type of Floor Screed to Choose? A Guide to Solutions
The decision on which screed to choose should be dictated by the building's specifics, the intended use of the rooms, and individual expectations, such as compatibility with underfloor heating or the need for additional insulation. Below, we present four key technologies from our offer, highlighting their advantages and ideal applications.
1. Concrete (Cement) Screeds – Durability and Versatility
This is a classic and the most commonly used solution, also known as a cement screed. A mixture of cement, aggregate, and water creates an incredibly solid subfloor that has been the standard in construction for years.
Key Advantages:
- High mechanical resistance: It perfectly withstands heavy loads, making it an excellent choice for garages, workshops, and utility rooms.
- Moisture resistance: Unlike anhydrite screeds, concrete performs excellently in wet rooms such as bathrooms, laundry rooms, or basements.
- Versatility: It can be used both indoors and outdoors (e.g., on terraces or driveways).
- Favorable price: It is one of the most economical solutions on the market.
When is it the right choice?
Choose a concrete screed when your priority is maximum durability, resistance to heavy loads, and moisture. It is a reliable foundation for almost any type of finish – from ceramic tiles to heavy natural stone.
2. Anhydrite Screeds – Ideal for Underfloor Heating
A modern alternative to traditional screeds, based on an anhydrite binder (a type of gypsum). Thanks to its liquid consistency, it creates a perfectly smooth and level surface.
Key Advantages:
- Excellent thermal conductivity: This is the best choice for underfloor heating systems. The liquid mass tightly envelops the heating pipes, minimizing energy loss and ensuring high efficiency.
- Self-leveling properties: It guarantees a perfectly even surface without the need for mechanical troweling, which shortens the working time.
- Speed of application: Anhydrite screed is poured much faster than concrete screed, and it can be walked on after just 24-48 hours.
- High strength: Despite a thinner layer, it achieves very good strength parameters, and its low shrinkage eliminates the risk of cracking.
When is it the right choice?
Anhydrite screed is the gold standard in modern residential construction, especially where underfloor heating is planned. It is ideal if you value time, perfect smoothness, and maximum efficiency of the heating system.
3. Styrofoam Concrete – Lightweight and Thermal Insulation
This is a specialized, lightweight cement mortar in which traditional aggregate is replaced with styrofoam granules. The result is a material with excellent insulating properties and low weight.
Key Advantages:
- Low weight: It does not excessively load the building's structure, making it ideal for renovating old buildings, attic conversions, and on floors with limited load capacity (e.g., wooden ceilings).
- Excellent thermal insulation: It provides an excellent insulating layer, reducing heat loss and dampening impact sounds.
- Ability to level large irregularities: It allows for simultaneous leveling of the subfloor, concealing installations, and creating an insulation layer.
When is it the right choice?
Styrofoam concrete is indispensable for renovating old buildings, on wooden ceilings, and wherever you need a lightweight, warm, and leveling subfloor. It's a 2-in-1 solution: stabilization and insulation.
4. Self-Leveling Screeds – Quick Renovation and Perfect Smoothness
These are thin-layer compounds whose main task is to quickly level and smooth the existing subfloor before applying the final finishing layer, such as panels, carpet, or parquet.
Key Advantages:
- Instant effect: A very short drying time allows for the continuation of renovation work after just a few hours.
- Perfectly smooth surface: It creates a mirror-like surface, which is essential for thin and flexible flooring materials (e.g., LVT vinyl panels).
- Ease of application: The liquid consistency makes the compound spread and level itself.
When is it the right choice?
Choose a self-leveling screed when you need to quickly and effectively level an old, uneven subfloor (e.g., old concrete). It is the ideal repair and finishing layer before installing modern floors.
