When you’re preparing a floor for tiles, vinyl, carpet, or wood, you might come across two similar terms: self-levelling screed and latex screed. While closely related, they’re not identical.
In this article, we’ll explain each type, highlight key differences, and help you decide which is best for your project.
What is Self Levelling Screed?
Cement-based
The most common self-levelling compounds are cement-based. They are mixed with water and poured over the surface, creating a smooth finish once set.
Applications
Cement-based self-levelling screeds are ideal for concrete floors, uneven surfaces, and where you need a solid, durable base.
Thickness
They can usually be applied at various depths, making them versatile for both minor levelling jobs and larger floor refurbishments.
What is Latex Screed?
Flexibility
Unlike cement-only compounds, latex screeds can handle slight movement without cracking.
Strength
The latex makes the screed stronger and more resistant to damage from regular foot traffic.
Applications
Latex screeds are often recommended for timber floors, floors with underfloor heating, or areas where only a thin layer of screed can be applied.
Key Differences at a Glance
| Feature | Cement-based Self-Levelling | Latex Self-Levelling |
|---|---|---|
| Composition | Cement + water | Cement + latex additive |
| Flexibility | Rigid | Flexible |
| Best for | Concrete, solid floors | Timber, uneven or heated floors |
| Cost | Lower | Higher (but adds value) |
FAQs – Your Common Screeding Questions
Q: Can you tile directly over latex screed?
A: Absolutely. Once fully cured and primed, latex screed offers a smooth, reliable base for tile adhesion.
Q: How long does self-levelling screed take to dry?
A: Generally, it can be walked on after 24 hours and ready for final flooring in 48–72 hours, depending on depth and conditions.
Q: Is latex screed more expensive?
A: It can cost more—but for floors that move or have special heating systems, it’s worth the investment to avoid future cracks.
Q: Do I need to mix it differently?
A: Yes. Latex screeds come ready to mix with a liquid latex additive—follow the manufacturer’s instructions for best results.
Q: Can I apply it myself?
A: For best results—especially with depth control and curing—it’s recommended to hire professionals like Complete Floor Screeds to ensure a flawless finish.
So, which Screed should you choose?
Concrete floor?
Go with a standard cement-based self-levelling screed.
Timber subfloor or underfloor heating?
