Benefits of Liquid Floor Screed
Liquid screed is a fast and efficient alternative to traditional hand-laid sand and cement screed. Its flowing consistency allows it to be pumped into position and installed accurately across large or complex areas.
- Fast, efficient pumped installation
- Accurate floor levels
- Excellent contact around wet underfloor heating pipes
- Suitable for domestic and commercial projects
- Practical for extensions, renovations and new builds
- Reduced screed depths may be possible, subject to the chosen product and floor specification
We can advise on the appropriate specification based on the floor construction, required depth, drying requirements and intended floor covering.
Liquid Screed for Underfloor Heating
Liquid screed is an excellent choice for floors containing wet underfloor heating. It flows around properly secured pipes, reducing air voids and providing consistent contact across the heated area.
Before screeding, the pipework should be pressure-tested and securely fixed. The insulation, membrane, perimeter edging and required screed depth must also be checked before installation.
The heating must not be switched on immediately after the pour. Commissioning should follow the screed manufacturer’s guidance after the required initial curing period.
Our Services
Our Liquid Screed Installation Process
Every installation begins with a review of the floor area, specified depth, construction, access and selected screed product. The following preparation and installation stages help us deliver a reliable result.
- Project assessment: We confirm the floor area, specified depth, construction, access and selected screed product.
- Preparation checks: Membranes, perimeter edging and insulation must be correctly installed before the pour.
- Underfloor heating checks: Wet UFH pipes must be securely fixed and pressure-tested where applicable.
- Delivery: The selected liquid screed is delivered to site in accordance with the agreed specification.
- Pumped installation: The screed is pumped into the prepared area and installed to the required depth and levels.
- Finishing: Our team dapples and finishes the installed screed in accordance with the product requirements.
- Aftercare: We provide guidance on access, ventilation, drying, UFH commissioning and preparation for floor coverings.
Frequently Asked Questions
What are the ingredients of liquid screed?
Liquid screed formulations vary by product. Cement-based and calcium sulphate screeds use different binders and additives, so the selected manufacturer’s technical datasheet should be followed.
Are there any other types of screed?
Yes, other than liquid screed, there are three types of screed, i.e.:
Bonded screed
Unbonded screed
Floating screed
Why is liquid screed suitable for underfloor heating systems?
Liquid screed offers low thickness as compared to conventional cement screed, with average thickness of 40mm with insulation and 50mm with UFH, thus leaving more room for insulation. It is also a good heat conductor, facilitating efficient heat transfer across the space.
How much time does it take to dry?
Liquid screed requires 24-48 hours to dry, based on the environment and temperature conditions. However, it will take a few more days to achieve its maximum strength.
Accurately Levelled Substrate
Liquid screed creates an accurately levelled substrate for the next stage of the flooring system, but it should not automatically be treated as a decorative final finish.
Depending on the screed product and intended floor covering, further preparation may include sanding, priming, moisture testing or a suitable smoothing compound. The flooring contractor should confirm the preparation and moisture requirements before tiles, timber, vinyl or other finishes are installed.
The Right Screed Specification
The correct screed depth and product depend on the floor build-up, insulation, underfloor heating, required drying time and final floor covering.
Send us your postcode, floor area, required depth, plans and preferred installation date. If you are unsure about the specification, we will help identify the information needed for an accurate quotation.
