If you’ve been around construction long enough, you’ll know that screed is one of those jobs people rarely think about until something goes wrong. A floor that isn’t level, cracks appearing under tiles, underfloor heating that never quite warms evenly — we’ve seen all of it. And more often than not, the root of the problem comes down to the type of screed used and how it was installed.
Over the last decade, we’ve worked with both traditional sand‑and‑cement mixes and modern liquid screed. Each has its place, but the difference in performance is becoming harder to ignore. Builders, homeowners, and flooring installers are all leaning toward liquid screed, and after pouring thousands of square metres ourselves, we understand why.
This isn’t a sales pitch — just an honest comparison based on what we’ve seen on site.
What Traditional Screed Does Well (And Where It Struggles)
Traditional screed has been around forever, and there’s a reason for that. It’s simple, familiar, and for small areas, it can still be a perfectly workable option. We’ve used it on tight renovation jobs where access was limited or where the client was working with a very tight budget.
But the limitations show up quickly:
- It relies heavily on the installer’s skill
- Larger areas are difficult to keep perfectly level
- It’s labour‑intensive
- Drying times can drag on
- It doesn’t naturally flow around underfloor heating pipes
We’ve had jobs in the past where a traditional mix was specified, and despite doing everything by the book, the finish still needed extra smoothing before flooring could go down. It’s simply a more hands‑on material, and that means more room for human error.
Where Liquid Screed Starts to Pull Ahead
The first time we poured liquid screed on a large open‑plan extension, the client stood there in disbelief watching the floor level itself. No raking, no frantic trowelling, no fighting with ridges. Just a clean, even surface forming in front of us.
That’s the biggest difference: liquid screed removes the guesswork.
Here’s what we consistently see on site:
1. A Flawless Finish Without the Hard Labour
Because it self‑levels, the surface ends up smoother and more consistent than anything you can achieve manually. Flooring installers often comment on how much easier their job becomes.
2. Perfect Pairing With Underfloor Heating
This is where liquid screed really earns its reputation. It flows around every pipe, eliminating air pockets and improving heat transfer. If you’re planning UFH, this combination is hard to beat.

3. Faster Installation and Quicker Turnaround
A full house can be poured in a morning. You can usually walk on it within 24–48 hours. That speed makes a huge difference when you’re juggling multiple trades.
4. Less Risk of Cracking
Traditional screed can shrink or crack if the weather turns or the mix isn’t perfect. Liquid screed is far more stable, especially in larger areas.
5. Better Thermal Performance
Because it fully encapsulates UFH pipes and can be laid thinner, it delivers more efficient heating and faster response times.
Cost: The Part Everyone Wants to Know About
Traditional screed is usually cheaper upfront. There’s no denying that. But when you factor in:
- Reduced labour
- Faster installation
- Fewer levelling issues
- Better performance with underfloor heating
- Less remedial work
Liquid screed often ends up being the more cost‑effective choice overall.
Which One Should You Choose?
Here’s the honest answer we give clients:
- Small areas, tight budgets, or simple rooms: traditional screed can still work.
- Anything involving underfloor heating, large open spaces, or tight timelines: liquid screed is almost always the better choice.
We’ve seen too many projects where traditional screed created unnecessary delays or issues that could have been avoided. Modern builds demand accuracy, speed, and efficiency — and liquid screed delivers all three.
Why This Matters for Your Project
Flooring is one of the last stages of a build, and by the time you reach it, most clients are eager to get the job finished. The last thing you want is a screed that needs extra smoothing, extra drying time, or extra money thrown at it.
Choosing the right screed at the start saves time, stress, and cost later on.

Final Thoughts
We’ve worked with both materials long enough to know their strengths and weaknesses. Traditional screed still has its place, but for most modern builds — especially those with underfloor heating — liquid screed is the smarter, cleaner, and more reliable choice.
