Standard Screeds - This is acceptable for regular residential usage and comprises a combination of sand and cement. This mixture comprises a 5:1 ratio of sand to cement. This 5:1 ratio standard screed will dry out at a rate of 1mm per day after laying.

Polymer Screeds - An extremely high strength flooring solution where a reduced thickness is required. Manufacturer's guidelines for setting times differ across the various product ranges.

Self-Levelling or Liquid Screeds - A latex and cement formula which can achieve the highest standard SR1 finish. Largely used to finish off a poor substrate level or damaged floor to enable the laying of a new flooring surface, such as tiles over the top of it. They can be as little as 1mm in depth, and because of the latex polymers, will still provide a high strength finish.

Industrial and Heavy Duty Screed - Made for maximum strength and durability in places where traffic is high or heavy loading on the floor is required.

Fibre Reinforced Screed - The preferred choice by professional screeders for use with underfloor heating systems. The fibres in this screed mix enhance it's durability and strength while also protecting against thermal cracking and shrinkage. At approximately one millimetre per day, it has the same curing rate to standard screed.

Fast Drying and Advanced Drying Screeds - If you have to use the area ASAP a fast drying screed can be employed. Most of the fast or advanced drying screeds are fibre reinforced and are ideal for a wide array of flooring projects where the speedier drying rate of 3-7mm is an advantage.


Good preparation is essential for a top quality screed surface that will be hard wearing and durable. Any oil, debris, paint and grease on the existing floor surface can adversely affect the bonding of the screed, and should be removed.

Any cleansing chemicals that are used during this process shouldn't leave any residues, and the floor base must be allowed to dry out naturally. If screeding over a cement or stone floor any cracks should be repaired to stop them from "travelling" through a screed layer and resulting in imperfections on the finished surface. A trustworthy Keynsham screeding contractor will pick up on such aspects during a on-site survey and make sure that all preparations are completed before moving on to the next stages of the floor screeding process.

A DPM (damp proof membrane) will be applied after the preparation work has been completed to stop ground moisture getting into the flooring materials and screeding. The DPM is made out of thick polythene sheeting and various layers could be used to serve as a moisture barrier for the screed.

If your property is located in a place where radon is found an extra barrier layer is necessary to stop radon gas from seeping through. If radon gas is present in severe doses then a full extraction and ventilation system might be needed beneath the screed which will extract any gases that might seep in from ground level.

As soon as these stages have been completed the screeding company will apply a sealant or primer to the prepared base. These primers and sealers will make certain the screed bonds successfully to the base and help to produce a high quality finished floor. On account of their special nature, only professional screeders in Keynsham are capable of using them correctly, safely and using bespoke equipment for the task.

Underfloor heating can now be installed and checked before screeding is poured. Insulation panels will be arranged and the heating pipes and wires will be firmly attached to prevent any movement while the screed is being poured. When properly installed an under floor heating system is an excellent way to warm up a room and decent quality screed will retain its heat, creating an even heat right across the floor surface.

The screed can now be prepared in situ and spread onto the floor base. The specific requirements of the room will determine the type of screeding that is used. For quick drying and advanced screeds there will be at least twenty four hours delay before it is able to be walked on, and a further 3 days minimum before any flooring material can be applied. If you are hoping to wind up with a properly finished and durable floor surface you should follow the manufacturer's guidelines with regards to standard and heavy duty screeds where the time period will be longer.

The SR standard of your screed can be verified once it has solidified sufficiently to be stepped onto. The standard SR test uses a 2 metre long straight-edge to check for any fluctuations in the floor surface.

  • SR1 - SR1 is the best level and permits only 3mm of deviation from the straight-edge.
  • SR2 - The normal standard flooring in commercial and industrial builds is normally SR2 and has a maximum possible deviation of 5mm across the whole screed.
  • SR3 - For a utility area or room where the quality of finish is fairly immaterial the SR3 is the standard and should have a maximum deviation measurement of 10mm or less.

There might also be a requirement for a structural engineer to carry out a soundness test. The testing will make sure that your newly laid screed is viable for the load point requirements set down in the original site survey. The screeding should be subjected to a drop hammer test to determine strength and flexibility in specific areas. Only trained structural engineers applying the British Standards BS8204 regulations are allowed to carry out such tests and sign off on the structural safety of screed flooring.

Coloured Floor Screeds

A flooring material commonly used in commercial or industrial settings is coloured floor screeds. A unique and distinctive finish is created by combining coloured aggregates, resins, and sealants to form these screeds. 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.

The branding of a business or the desired aesthetic in a space can be accomplished by customising multi-coloured screeds. 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 an ideal choice for cleanroom environments. Coloured floor screeds offer architects and designers the flexibility to create bespoke flooring designs tailored to their unique project demands by allowing them to select aggregates based on size, shape, and colour. All in all, the combination of practicality and versatility in multi-coloured floor screeds makes them a flooring solution that can enhance both style and function in any commercial or industrial space.

Granolithic Screeding

Granolithic screeding refers to a type of flooring that consists of a mixture of aggregate, cement and sand. It is applied in a relatively thin layer and then smoothed to provide a durable, seamless and hard-wearing surface. It is often used in commercial, public and industrial buildings where there is heavy foot or machinery traffic.

This technique is generally used in industrial and commercial buildings, high-traffic residential areas, and spaces that require chemical and abrasion resistance. The resulting surface is easy to clean, durable, and provides the ideal base for other flooring products.

The granolithic screeding process involves a number of steps, including preparation of the concrete base, mixing of the screed mixture, laying of the mixture, and curing of the screed. Correct mixing, application and curing techniques are crucial to guarantee the strength and durability of the final surface. Additionally, the screed should be allowed to fully cure before any flooring materials are installed on top of it.

Latex Screeds

When the make-up of your floor's surface means that a degree of flexibility is required, it may be advantageous to apply a latex screeding, as opposed to one with a more rigid finish. A latex floor screed comes in two parts, a bag and a bottle, with the bag containing a cement powder, and the bottle containing a liquid latex. The latex liquid additive replaces the water which would normally be used in a screed mix, and is more flexible and quicker drying than other types of screed.

This latex screed product is used to level a sub-floor before the final decorative surface is laid. Suitable for substrate of stone tiles, asphalt, concrete, sand/cement and wood, this gives a perfect surface for the application of adhesives which is also smooth and resilient. If your sub-floor has any movement in it, this type of floor screed will still produce a crack-free, flexible finish, on which your final floor coverings can sit.

When installing a "floating" screed, for example when an unbonded screed is being laid on the top of a membrane of thermal or acoustic insulation, thicknesses of 50 to 65 millimetres may be required, and latex floor screeds are not suited to this purpose.
