TYPES OF SCREED
Standard Screeds - Widely used in domestic projects where the mix of sand and cement is perfect for normal floor traffic usage. The ratios involved are five parts sand to one part cement. Once laid this 5:1 ratio dries at a rate of one millimetre per day.
Fibre Reinforced Screed - Used mostly with under floor heating and is the favoured choice in these projects. This is due to the improved strength and protection against thermal cracking and shrinkage provided by the special fibres within the screed. It dries out at an identical rate to a standard screed, at about one millimetre per day.
Polymer Screeds - Provides a high level of strength with a minimal thickness. Maker's guidelines for drying times vary across the product ranges.
Fast Drying and Advanced Drying Screeds - As the name suggest, this screed dries rapidly and allows you to use the screeded area much sooner. Drying at a rate of three to seven millimetres, subject to the specialised mix, they're generally a fibre reinforced type of screed and are perfect for projects that have tight deadlines.
Industrial and Heavy Duty Screed - Where levels of traffic are high or heavy loading of the floor is needed, heavy duty screeds deliver maximum durability and strength.
Liquid or Self-Levelling Screeds - A cement and latex solution which can achieve the highest standard of finish to SR1 levels. Primarily used to improve a damaged floor or poor substrate level to enable the laying of a new flooring surface, such as tiles on top of it. Even with a thickness of just one millimetre, the latex polymers within the mixture provide a high strength screed for a wide range of uses.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a high quality finish which is durable and hard wearing, time should be devoted to preparing the area prior to any screed being laid. It's crucial that any contaminants such as grease, paint, debris or oil is eradicated from the floor surface before pouring any screed, as these can affect the adhesion capability that a quality floor screed needs.
If cleansing products have been used it's crucial to remove any residues of detergent or soap, and leave the surface to dry naturally. At this stage any cracks need to be repaired because these can travel up through a newly laid screed and be reflected in the completed floor surface. An on-site survey will allow your Englefield Green screeding installer to highlight these preparation areas and complete them before beginning to pour the screeding.
Before any screeding can be poured a damp proof membrane (DPM) will have to be installed to protect the final flooring and screed from moisture damage. There may be two or three layers of different thicknesses of polythene to act as a barrier between the screed and the insulation layer.
Another airtight barrier might be needed if your property is in a location that is known to be prone to radon gas emissions. This could be as simple as an airtight membrane, or in more serious cases an extraction and ventilation system will be installed underneath the floor screed to take away any influx of radon gas from the ground.
The final step of the surface preparation process is the spraying or painting of a sealer or primer. A primer helps with the screed bonding process to the base and membranes and different varieties exist according to which screed type is being used. These materials need qualified technicians to apply them in the correct proportions by using airless sprays and other bespoke equipment.
If you are going to be installing underfloor heating, now is the time that it will need to be properly laid out and installed. The heating pipes and cabling are firmly attached to insulation panels to prevent any movement and make certain that they're held in the correct position. When expertly installed an under floor heating system is an effective way to warm a room and good quality screeding retains its heat, generating an even level of warmth across the floor.
If you are not putting in under floor heating the screed will now be mixed and prepared in situ and laid. Your intended use of the room will help your screeding specialist on which form of screed is appropriate for your requirements. After the pouring of the screed there'll be at least 24 hours (for quick drying and advanced screeds) before you can walk over the surface, and a seventy two hours minimum setting period before the laying of any floor coverings. If you're laying standard or heavy duty screeds the curing time is increased and the manufacturer's guidelines must be followed in order to get the best finish to your floor.
You can assess the SR level of the completed screeding once it's solidified enough for walking on. The standard SR test uses a 2 metre long straight-edge to check for any variations in the floor surface.
- SR1 - Over the whole floor area, if there are no disparities greater than three millimetres from the straight-edge, you've got a top quality SR1 specification surface.
- SR2 - The normal standard flooring in industrial and commercial builds is classed as SR2 and has a maximum possible deviation of 5mm across the whole screeded floor.
- SR3 - SR3 is basic utility standard where a perfect finish is not needed. This specification allows for a maximium deviation of 10mm.
If you need to check the screed floor for load bearing, a structural engineer is necessary to conduct the testing. This assessment will establish the overall strength of the screed surface and the suitability for its proposed use. This can include what's known as a drop hammer test which records specific data on the flexibility and strength of the screed. Any screeding that has load bearing requirements must be okayed by a fully qualified structural engineer heeding the BS8204 regulations.

Latex Screeding Englefield Green
When the surface of a floor needs a level of flexibility, it is best to use a latex screeding. Usually coming in two parts, latex screeds comprise a cementitious powder and a liquid latex mixture. The latex liquid additive replaces the water that would typically be used for mixing screed, and is far more flexible and quicker drying than other types of screed.
This latex product is used for levelling sub-floors in advance of the installation of the final decorative surface. Giving a resilient, smooth surface which is ideal for the application of adhesives, this is is appropriate for use on subfloors of concrete, sand/cement, wood, stone tiles and asphalt. If your sub-floor has any movement in it, this latex screed will still give you a crack-free, flexible finish, on which your final floor coverings can sit.
Latex screeds are not suitable where "floating" screeds are required, for instance when an unbonded screed is being laid on top of a layer of either acoustic or thermal insulation, such as could be the case when you are screeding on top of underfloor heating, and thicknesses of 50-75mm may be required.
Granolithic Screeding
Granolithic screeding is a process of creating an even and smooth surface for floor coverings like tiles or carpets. It involves mixing cement, aggregate and sand to form a mixture, which is then applied to a concrete sub-base. The mixture is levelled with a straight edge to give it a smooth, seamless surface.
Granolithic screeding is generally used in commercial and industrial buildings and also in high-traffic areas in residential buildings. It is also commonly used in areas where chemical and abrasion resistance are required. The resulting surface is hard and smooth, which makes it easy to clean and maintain, and provides a perfect base for other flooring products.
Granolithic screeding is typically applied over a concrete base, and the surface is typically treated with a curing compound to make sure it sets properly. Once cured, it creates a seamless floor with a smooth, hard surface that is resistant to excessive wear. It is also resistant to chemicals and water, which makes it suitable for use in environments where there's a chance of spills or exposure to dangerous materials.
Coloured Floor Screeds
Industrial or commercial settings usually use multi-coloured screeds as a flooring material. These screeds are made up of a combination of coloured resins, aggregates, and sealants that are mixed together to create a unique and decorative finish. The ability to withstand wear and tear and provide a non-slip surface make them a popular choice for areas with machinery or heavy foot traffic.
To achieve a specific aesthetic or match the brand of a business, multi-coloured screeds can be tailored accordingly. Their easy-to-clean and maintain properties make them a favourite option for facilities that require a high standard of hygiene. The seamless finish offered by multi-coloured screeds, which eliminates joints or grout lines, makes them the perfect choice for cleanrooms and similar environments. Overall, multi-coloured floor screeds are a flooring solution that can add style and function to any industrial or commercial space, making them a versatile and practical choice.
Screed Reinforcement
Screed reinforcement is employed to bolster the strength and durability of concrete screeds. A base layer is covered with thin and flat layers of concrete, called screeds, to create a level surface. In building projects, they have a common use as flooring, and they can also serve as a finishing layer for walls and ceilings.
To prevent cracking and increase strength, reinforcement materials like polypropylene fibres, wire or steel mesh are mixed into the screed during installation. This reinforcement helps the surface to evenly distribute weight and load, as well as improve its ability to resist impact, thermal changes and abrasion.
The risk of shrinkage and cracking due to temperature or humidity changes is reduced by reinforcement, and this also enhances the screed's durability and strength. By utilizing screed reinforcement, screeding professionals can guarantee that their projects will provide a functional and high-quality surface that will last for years to come.
Screed Floor Removal
Extracting and disposing of the pre-existing screed from a surface is the essence of screed floor removal. This is quite often necessary when upgrading or refurbishing a floor. The removal process requires specialist equipment and techniques to successfully break down and remove the screed layer. The preparation of the surface for new flooring material or other alterations is made possible by this. By specialising in screed removal, contractors ensure the efficient and safe removal of the old screed, enabling the floor to start afresh, whether for repairs, upgrades or design alterations.
