How to Maintain Liquid Screed Floors for Long-Term Durability
How to Maintain Liquid Screed Floors for Long-Term Durability
Introduction
Liquid screed has become the preferred flooring solution for builders, developers, and contractors across Surrey, Sussex, Hampshire, and the South East — and for good reason. Its smooth, level finish and excellent thermal properties make it ideal for modern homes and commercial spaces. However, to ensure it performs at its best over time, proper maintenance and aftercare are essential.
This guide outlines the key steps to maintaining liquid screed floors, ensuring long-term durability, stability, and performance.
1. Allow Proper Drying and Curing
The first step in maintaining a liquid screed floor happens immediately after installation — allowing it to cure correctly.
Avoid walking on the screed for the first 24–48 hours after pouring.
Keep the area ventilated but not draughty to support even drying.
Never use direct heat sources like gas heaters or blowers — they can cause cracking or curling.
For projects in Guildford, Horsham, and Brighton, maintaining stable temperature and humidity levels during curing is particularly important due to fluctuating seasonal conditions.
2. Control Site Conditions During Drying
After the initial curing phase, site conditions should remain stable.
Maintain ambient temperatures between 15°C and 20°C.
Provide adequate airflow to encourage moisture evaporation.
Avoid covering the surface with impermeable materials until the screed has fully dried.
If you’re using underfloor heating, commissioning it correctly can help accelerate drying safely (see section 5 below).
3. Protect the Surface from Damage
During construction, the screed surface can be vulnerable to scuffs, chips, or impact damage from trades working above it.
Cover the screed with breathable protection sheeting once it is walkable.
Avoid using polythene or sealed coverings that trap moisture.
Prevent heavy objects from being dropped or dragged across the floor.
These precautions ensure the screed remains intact and free from defects before final floor coverings are installed.
4. Moisture Testing Before Floor Coverings
One of the most common causes of screed failure is applying floor finishes too soon.
Always conduct a moisture content test before laying tiles, wood, or carpet.
The moisture level should typically be below 0.5% for anhydrite and below 2% for cementitious screeds, depending on manufacturer guidance.
Rushing this step can lead to trapped moisture, causing warping or adhesive failure — issues that are costly to fix later.
5. Commissioning Underfloor Heating
If your liquid screed is paired with underfloor heating (UFH), correct commissioning is vital to ensure both systems perform optimally:
Wait at least 7 days after screed installation before starting.
Gradually increase the water temperature by 5°C per day until the maximum operating temperature is reached.
Maintain that temperature for 3–5 days, then reduce gradually.
This controlled process helps remove residual moisture while avoiding thermal shock or cracking.
6. Regular Cleaning and Care
Once floor coverings are installed, ongoing maintenance is simple but important:
Sweep or vacuum regularly to prevent dirt buildup.
Use pH-neutral cleaning products suitable for your chosen flooring type.
Avoid excessive moisture when cleaning — even sealed floors can absorb water through joints over time.
For polished or finished screed floors, periodic resealing may be recommended to preserve the surface sheen and resistance.
7. Periodic Inspections
For commercial or multi-unit developments, schedule regular floor inspections to identify early signs of wear or damage.
Look for cracks, movement joints opening, or uneven surfaces.
Address any water ingress or heating faults promptly to prevent subfloor deterioration.
Proactive maintenance ensures the screed continues performing for years, protecting your investment and avoiding costly remedial work.
Conclusion
Liquid screed floors are designed for longevity — but like any high-performance building material, they require proper care. By controlling drying conditions, protecting the surface during construction, testing moisture levels, and maintaining a regular cleaning routine, developers and homeowners in Surrey, Sussex, and the South East can enjoy smooth, durable, and efficient floors for decades.
