TYPES OF SCREED
Standard Screeds - A mix of cement and sand which is okay for normal domestic usage. The ratios involved in standard screeds are five parts sand to one part cement. Once laid this 5:1 ratio will dry at a rate of one millimetre each day.
Advanced Drying and Fast Drying Screeds - If there's a need to move forward urgently with the flooring on account of time constraints, these screeds dry more speedily than standard screeds. The majority of the fast or advanced drying screeds are fibre reinforced and are appropriate for a wide range of flooring projects where the faster curing rate of 3-7mm/day is a welcome advantage.
Polymer Screeds - When a reduced thickness of floor is necessary because of building requirements, a polymer screed provides a high strength resolution to the situation. Manufacturer's guidelines for drying times differ across the various product ranges.
Industrial and Heavy Duty Screed - A screed designed for heavy traffic and high load areas where maximum strength and durability is essential.
Liquid or Self-Levelling Screeds - When the highest possible standard of finish is needed this mixture of latex and cement is employed to produce SR1 level screeding. Primarily used to finish off a damaged floor or poor substrate level to enable the laying of a brand new flooring surface, such as tiling on the top of it. They can be as little as one millimetre in depth, and due to the latex polymers, will still provide high strength.
Fibre Reinforced Screed - The favoured option where underfloor heating is being installed in residential homes in London Colney. The special fibres in the screed increase it's strength and durability whilst also protecting against thermal shrinkage and cracking. It dries at the same rate as a standard screed, at about one millimetre per day.
SCREEDING PREPARATION AND INSTALLATION
Preparation is vital for a quality finished screed surface that will be hard wearing and durable. Any grease, oil, paint and debris on the existing floor level can adversely affect the adhesion of the screed, and must be eliminated.
If any cleaning products were used during this stage it is crucial to make sure that no residues of soaps or other cleaning products are left on the surface and it is permitted to dry out naturally. If screeding over a stone or cement floor then all cracks should be repaired to stop them from "travelling" up through your screed layer and producing deviations on the final floor surface. A site survey will allow the screeding installer to take note of these preparation areas and complete them before beginning to pour the screeding.
A DPM (damp proof membrane) will be installed after the preparation work has been done to stop ground moisture getting into the screeding and floor materials. The DPM is made out of thick polythene sheet and different layers could be used to act as a moisture barrier and air insulating layer for the screed.
If your house is situated in an area where radon is found an additional barrier layer is essential to prevent radon gas from getting through. This can be as simple as an air-tight membrane, or in more serious cases a ventilation and extraction system will need to be installed underneath the floor screed to take away any influx of air and gas from the ground.
Once the base has been properly prepared and any membranes installed, a sealant or primer is then put on. These sealers and primers will make sure the screed bonds perfectly to the base and help achieve a quality finished floor. These products require experienced technicians to apply them in the appropriate proportions by using custom-made equipment, such as airless sprays.
If you're installing underfloor heating, now is the time that it will need to be correctly laid out and installed. Insulation panels can be laid out and the cabling and heating pipes will be securely mounted so there's no movement while the screed is applied. Underfloor heating is one of the most effective ways to heat a room and a properly installed system will provide even warmth all over the floor.
If you aren't putting in under floor heating the screed will now be mixed and prepared on site and laid. Your screeding company will give you advice on which screed type is appropriate for your requirements, according to your intended use of the room. After the application of the screed there's a minimum 24 hours (for quick drying and advanced screeds) before you are able to walk over the surface, and a 72 hour minimum setting time before the laying of any floor coverings. If you are looking to end up with a nicely finished and durable floor surface you must stick to the manufacturer's guidelines with regards to standard and heavy duty screeds where this time period will be longer.
You can test the SR standard of the completed screed once it's hardened enough to walk on. The test involves using a 2 mtr long straight-edge laid on the surface and any variations from true are measured.
- SR1 - SR1 is the best quality and allows just three millimetres of disparity from the straight-edge.
- SR2 - SR2 is the classification for standard floors in industrial and commercial projects and can deviate from the straight-edge by up to five millimetres.
- SR3 - For other floors where the finish is comparatively immaterial SR3 is the standard and should have a maximum deviation measurement of 10 millimetres or less.
There might also be a requirement for a qualified structural engineer to conduct a soundness test. This assessment will establish the overall strength of the screeded surface and its viability for the intended use. An assessment called the drop hammer test will be performed at various areas on the screed and the outcomes recorded. Only fully qualified structural engineers obeying the BS8204 regulations are allowed to perform such tests and sign off on the structural safety of the screeding.

Latex Screeding London Colney
It is better to use a latex self-levelling screeding when a certain degree of flexibility is necessary in the surface of a floor. Latex screeds normally comprise 2 parts - a cement-based smoothing compound, and a liquid latex mixture. The liquid latex part takes the place of the water that is used in standard screeds, meaning that it is more flexible and quicker drying.
This latex product is used for levelling-out subfloors in advance of the installation of the final decorative surface. Providing a resilient and smooth surface that's perfect for the application of adhesives, this screed is is appropriate for use on sub-floors of sand/cement, wood, quarry tiles, concrete and asphalt. This type of floor screed will give you a crack-free, flexible finish, even if there's a bit of movement in your sub-floor.
With "floating" screeds, for example when an unbonded screed is being laid on top of a layer of either thermal or acoustic insulation, latex flooring screeds will not be a suitable choice. Floating screeds with a depth of 50 to 75 millimetres are frequently used over underfloor heating.
Multi-Coloured Floor Screeds
In commercial or industrial settings, multi-coloured screeds are frequently utilised as a flooring material. These screeds are formed by mixing coloured aggregates, resins, and sealants, resulting in a distinct and decorative finish. The ability to withstand continuous wear and tear and provide a non-slip surface make them a popular choice for areas with heavy foot traffic or machinery.
Multi-coloured screeds provide the flexibility to match the brand of a business or achieve a desired aesthetic in a space through customisation. Their ease of cleaning and maintenance makes them a sought-after option for facilities that demand a high level of hygiene. The seamless finish offered by coloured screeds, which eliminates joints or grout lines, makes them the perfect choice for cleanrooms and similar environments. All in all, coloured screeds are a versatile and practical flooring solution that can add both style and function to any commercial or industrial space.
What Does Screeding Do?
Within construction projects, screeding serves several vital purposes:
- Compatibility with Floor Finishes.
- Stability and Structural Integrity.
- Smoothing and Levelling.
- Underfloor Heating System Support.
- Improving Thermal and Sound Insulation.
- Subfloor Corrections.
- Load Distribution.
- Surface Protection.
Essentially, a stable, durable and level floor surface is achieved through the vital role of screeding. By maintaining a solid foundation, it enables the floor finish to uphold its quality and aesthetics, and endure the demands of day-to-day use for many years to come.
Screed Floor Removal
Existing screed can be extracted and eliminated from a surface through the process of screed floor removal. It becomes necessary in many instances during floor upgrades or refurbishments. Specialist techniques and equipment are employed in the removal process to break down and remove the layer of screed in an effective manner. This grants the opportunity to prepare the surface for new flooring material or other modifications. Expert contractors in screed removal carefully eliminate the old screed, guaranteeing efficiency and safety, and allowing the floor to embark on a fresh journey, whether for upgrades, design alterations or repairs.
