Screeding for tile installation: What it is and Why it matters
“Ever noticed a tiled floor that looks uneven, with some tiles sitting higher than others or cracking over time? Chances are, the problem isn’t the tiles themselves but what’s underneath them. That’s where screeding comes in—an essential but often overlooked step in tile installation that ensures a strong, level surface for your tiles to rest on.”
If you’re planning a tiling project, whether in a home, office, or commercial space, understanding the role of screeding can save you from costly repairs and ensure a long-lasting, professional finish. Let’s break down what screeding is, why it matters, and how it affects the durability and appearance of your tiled surfaces.
What is Screeding?
Screeding is the process of applying a smooth, level layer of material—usually a sand-cement mixture or self-leveling compound—over a subfloor to create an even base for tile installation. This step is crucial in ensuring the tiles adhere properly and remain durable over time.
A well-executed screed provides:
✅ A level surface for easy and precise tile installation
✅ Even weight distribution to prevent cracks or tile movement
✅ Improved adhesion, reducing the risk of tiles lifting over time
✅ A solid foundation for underfloor heating (if installed)
Without proper screeding, tiles can suffer from lippage (height differences between adjacent tiles), cracking due to uneven pressure, or poor adhesion leading to costly rework.
Types of Screeds used in tiling
Depending on the project, different types of screeds can be used to achieve the best results. Here are the most common ones:
1. Traditional sand-cement Screed
A mix of sand, cement, and water, laid manually and leveled with a straightedge.
Best for areas that require a strong, thick base.
Requires curing time before tiling can begin.
2. Bonded vs. Unbonded Screed
Bonded screed is directly adhered to the concrete substrate for a solid base.
Unbonded screed is laid over a membrane, useful for preventing moisture issues.
Choosing the right screed depends on the subfloor condition, tile type, and project requirements.
Why Screeding matters for long-lasting tiles
Skipping or poorly executing screeding can lead to uneven tiles, cracks, and water damage—all of which compromise the durability and aesthetics of your
