TYPES OF SCREED
Standard Screeds - A mix of sand and cement which is okay for normal domestic usage. The ratios involved in standard screeds are five parts sand to one part cement. After laying a standard screed mix dries out at a rate of just 1mm/day.
Self-Levelling or Liquid Screeds - A latex and cement formula which can produce the highest standard SR1 finish. Mostly used to finalise a poor substrate level or damaged floor to enable the laying of a new flooring surface, such as tiles on the top of it. This liquid screed can be poured to a thickness of just 1mm, but will still provide a strong surface for a wide variety of flooring materials.
Polymer Screeds - These provide a high level of strength with a minimal thickness. Because of their different chemical compositions, polymer screeds have varying drying times which can be verified by checking manufacturer's guidelines.
Fibre Reinforced Screed - Used with under floor heating and is the recommended option in such projects. The fibres in this screed mix improve overall durability and strength whilst also safeguarding against thermal shrinkage and cracking. It has a setting rate of one millimetre per day.
Advanced Drying and Fast Drying Screeds - If you have to use the area in question at the earliest opportunity a fast drying screed can be utilised. Drying at a rate of 3-7mm/day, subject to the mix, they are usually a fibre reinforced screed and are perfect for flooring projects which have tight deadlines.
Industrial and Heavy Duty Screed - A screed designed for high load and heavy traffic areas where maximum strength and durability is essential.
SCREEDING PREPARATION AND INSTALLATION
Preparation is essential for a high quality screed surface that will be hard wearing and durable. Any grease, debris, paint and oil on the original floor surface can adversely affect the bonding of the screed, and should be eradicated.
If cleaning products have been used it is important to remove any residues of soap etc, and allow the surface to dry naturally. If screeding over a cement or stone floor all cracks should be repaired to stop them from "travelling" up through a screed layer and producing deviations on the final surface. During an on-site survey your Chadwell St Mary screeding installer will ascertain what preparation work is required before any actual screeding work starts.
To protect the screed layer and flooring materials from dampness rising up through the ground, a damp proof membrane (DPM) will have to be installed. There could be two or three layers of varying thickness polythene to act as a barrier between the insulation layer and screed.
If your property is located in an area where radon gas is present a supplementary barrier layer is essential to prevent radon gas from getting through. A simple air-tight membrane might be suitable in areas with relatively low radon emissions, however in more serious situations there might have to be a more complex extraction system to take away any ground penetrating radon gas.
The final phase of surface preparation is the painting or spraying of a primer or sealant. These primers and sealers will ensure the screed bonds successfully to the floor base and help produce a quality finished floor. These products require certified tradesmen to apply them in the right ratios by using tailor-made equipment, such as airless sprays.
This is the time that under floor heating can be laid out in the correct manner and installed. The cabling and heating pipes are firmly attached to insulation panels to prevent any movement and make sure that they're positioned correctly. Warmth will be evenly spread across the floor in an expertly fitted underfloor heating system, and with it being an efficient method of heating, it is an ideal choice for many Chadwell St Mary home restoration projects.
Obviously, if you're not putting in under floor heating, you simply ignore this step and get on with applying the screeding. Your screeding specialist will have given you advice and guidance on which screed type is best for your needs, according to your proposed use of the room area. Bear in mind that even quick drying screeds have a minimum of twenty four hours before you can walk on any screeded surface and a minimum three days before any floor coverings can be applied. This time period is longer for standard and heavy duty screeds and the manufacture's guidelines should be followed to the letter to achieve the optimum finish and durability of the floor.
You can check the SR level of the completed screeding as soon as it is hard enough to walk on. Using a 2 metre straight-edge the surface is checked for any dips, ridges and deviations in the screed surface.
- SR1 - Over the whole screed area, if there are no deviations of more than 3mm from the straight-edge, you've got a top quality SR1 level surface.
- SR2 - The normal standard flooring in industrial and commercial builds is classed as SR2 and has a maximum deviation of five millimetres across the entire screeded floor.
- SR3 - If the deviation around the room is ten millimetres or less the screeding quality is specified as SR3 and is the standard required for garage and utility areas.
If your screed has been laid with specific loading in mind then a qualified structural engineer is going to be needed to conduct the assessment. Using specialist equipment the engineer will verify the screeded surface strength and suitability of use in a load bearing setting. An assessment called the drop hammer test is performed on various areas of the screed layer and the outcomes recorded. Any screed flooring that's got load bearing requirements must be sanctioned by a trained structural engineer following the BS8204 regulations.

Coloured Floor Screeds
A flooring material widely used in industrial or commercial settings is coloured screeds. These screeds are made up of a combination of coloured resins, aggregates, and sealants that are blended together to create a unique, decorative finish. In areas with machinery or heavy footfall, they are frequently utilised due to their ability to withstand wear and tear and provide a durable, slip-resistant surface.
Customising multi-coloured screeds is an effective way to match the brand of a business or create a particular aesthetic in a space. Facilities that demand a high standard of hygiene often select them due to their ease of cleaning and maintenance. All in all, coloured floor screeds offer a practical and versatile flooring solution that can improve both the style and function of any commercial or industrial space.
Latex Floor Screeds Chadwell St Mary
When a floor's surface needs a bit of flexibility, it is wise to use a latex floor screed. Usually coming in 2 parts, latex floor screeds comprise a cement-based powder, and a liquid latex mixture. The liquid latex solution actually replaces the water that would typically be used in a screed mix, and is quicker drying and more flexible than other types of screed.
Before the installation of your chosen decorative surface, this latex compound is used for levelling sub-floors. Giving a smooth, durable surface which is ideal for the application of flooring adhesives, this screeding is is suitable for use on sub-floors of wood, asphalt, sand/cement, concrete and quarry tiles. If your sub-floor has any movement in it, this type of latex floor screed will still provide a crack-free, flexible finish, onto which your final floor coverings can be laid.
When using a "floating" screed, i.e. when screed is being laid on top of underfloor heating, depths of 50 to 65 millimetres may be required, and latex floor screeds aren't suitable in this case.
Granolithic Screeding Chadwell St Mary
Granolithic screeding is an extremely popular flooring material which is used widely in heavy-duty environments due to its durability and strength. It's made from a mixture of aggregate, cement, sand, and sometimes pigments, which are combined to make a mortar-like mixture. The mixture is poured onto the floor and then smoothed out to a level surface.
The resulting flooring is easy to clean, hard-wearing and slip-resistant, making it ideal for use in areas with high foot traffic, such as factories, schools and shopping centres.
The granolithic screeding process involves preparation of the concrete base, mixing the screed mixture, laying the mixture, and giving it time to cure. Appropriate application and curing techniques are vital for the strength and longevity of the screed. The screed must be fully cured before any additional flooring products are installed.
Screed Reinforcement
To enhance the durability and strength of concrete screeds, screed reinforcement is utilised. A base layer is covered with thin and flat layers of concrete, called screeds, to create a level surface. They find common use in construction projects as flooring, but they can also be utilised as a finishing layer for walls and ceilings.
To prevent cracking and increase strength, reinforcement materials like fibres, steel mesh or wire are mixed into the screed during installation. By distributing load and weight evenly across the surface, reinforcement improves its resistance to abrasion, impact and thermal changes.
The risk of shrinkage and cracking caused by humidity or temperature changes is reduced by the reinforcement process, in addition to improving the screed's strength and durability. The selection of screed reinforcement material for a project may be dependent on specific requirements and can be influenced by factors such as finish, load capacity and thickness. Correct installation of the reinforcement is crucial to make sure that it is evenly distributed throughout the screed and doesn't get displaced over time. To maintain the quality and structural integrity of screeds, it's essential to use screed reinforcement, resulting in a long-lasting and reliable surface for a range of applications.
What Does Screeding Do?
The use of screeding in construction projects serves several key purposes:
- Levelling and Smoothing.
- Compatibility with Floor Finishes.
- Improving Thermal and Sound Insulation.
- Corrections to Subfloors.
- The Even Distribution of Loads.
- Surface Protection.
- Underfloor Heating System Support.
- Stability and Structural Integrity.
In a nutshell, screeding assumes a vital role in the creation of a level, durable and stable floor surface. It guarantees a solid foundation for the floor finish, enabling it to maintain its quality and aesthetics and endure the demands of everyday use over an extended period.
