Any errors or imperfections in the screeding (as might arise with SR2 or SR3) may cause issues with laying flooring owing to flat spots, ridges, indentations in the floor surface.
The regulations and guidelines specified in the British Standards BS8204 must be observed by any Kempston floor screeding contractor and they must also be certified by the manufacturers of specialist screeding materials (Gypsol, Cemfloor, Flowcrete etc.) to substantiate their competence and safe working practices.

TYPES OF SCREED
Standard Screeds - Frequently used in residential flooring projects where the blend of sand and cement is acceptable for normal footfall use. 5 parts sand to 1 part cement is the typical mixture for standard screed. After laying a standard screed mix sets at a rate of 1mm/day.
Polymer Screeds - Provides a high level of strength with a reduced thickness. Because of their different chemical compositions, these polymer screeds have varying setting times which you can verify by viewing manufacturer's own product guidelines.
Fast Drying and Advanced Drying Screeds - If there is a need to use the area at the earliest opportunity a fast drying screed can be employed. They are usually atype of screed which can dry at a rate of between three and seven millimetres per day and are used in time dependent projects.
Fibre Reinforced Screed - The expert's choice for residential use on top of under floor heating. The greater strength and flex offered by the fibres in the screed mix help protect the floor from thermal shrinkage and cracking. At roughly one millimetre per day, it has an identical drying rate to standard screed.
Self-Levelling or Liquid Screeds - Used to provide the highest quality of finish, especially where SR1 levels are necessary, by a latex and cement formula. Largely used to finish off a poor substrate level or damaged floor in order to lay a new flooring surface, such as vinyl planks on the top of it. These can be as little as 1mm in depth, and thanks to the, will still provide high strength.
Industrial and Heavy Duty Screed - A screed that's designed for high load and heavy traffic areas where maximum durability and strength is crucial.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a high quality finish which is hard wearing and durable, time should be spent on preparing the area prior to any screeding material being laid. Any oil, paint, grease and debris on the original floor level can adversely affect the adhesion of the screed, and should be eliminated.
If any cleaning products are used during this stage it is important to ensure that no residues of soaps or detergents are left on the floor surface and it is permitted to dry out naturally. It's vital to fix any cracks in the base to stop them being mirrored and "travelling" upwards into your freshly screeded floor. During a site survey the screeding specialist will ascertain what preparation work is required before any actual screeding work begins.
A damp proof membrane (DPM) will be put down after the preparation work has been completed to stop ground moisture getting into the flooring materials and screeding. The damp proof membrane is made of thick polythene sheeting and various layers might be used to act as a moisture barrier and air insulating layer for the screeding.
If your house is situated in an area where radon gas is present an additional barrier layer is necessary to stop radon gas from entering. If radon is present in severe doses then a complete ventilation system may be installed under the screed which will extract any gases that could seep in from ground level.
As soon as these steps have been taken the screeders will apply a primer or sealer to the prepared base surface. A primer assists in the screed bonding process to the base and membranes and different varieties exist according to which screed type is being used. Equipment such as airless sprays will usually be used to apply a sealant or primer, by qualified screeding installers in Kempston following the manufacturer's guidelines and safety advice.
Underfloor heating can now be laid out, installed and tested before screeding is poured. The heating pipes and wires are firmly attached to insulation panels to prevent any movement and make certain they are positioned correctly. When skillfully installed an under floor heating system is an efficient way to warm a room and good quality screeding retains its heat, producing an even heat across the floor surface.
If you're not fitting underfloor heating the screed can now be prepared in situ and poured. Your screeding specialist will have given you guidance and advice on which kind of screed is appropriate for your needs, in line with your proposed use of the room. For quick drying and advanced screeds there will be at least a 24 hour delay before it can be walked on, and a further Three days minimum before you can lay any flooring materials. This timescale is increased for standard and heavy duty screeds and the manufacture's product guidelines must be followed to the letter to create the best finish and durability of the floor.
The SR standard of your screed can be ascertained once it has solidified sufficiently to be walked upon. Using a 2m straight-edge the surface is examined for any deviations, dips and ridges in the surface of the screed.
- SR1 - SR1 is the best level and allows just 3 millimetres of disparity from the straight-edge.
- SR2 - SR2 is for normal standard floors in industrial and commercial projects and can deviate from the straight-edge by as much as 5mm.
- SR3 - SR3 is basic utility standard where a quality finish is not needed. This specification can have a maximum permissible deviation depth of 10 millimetres.
If your screeding has been laid with particular loading in mind then a qualified structural engineer will be necessary to carry out tests. The assessment will make sure that your newly laid screed is suitable for the load bearing requirements laid out in the original site survey. The screeding could be given what is known as a drop hammer test to determine strength and flexibility in distinct areas. The specialist testing and measurement tools involved mean this can only be undertaken by a certified structural engineer following the guidelines of BS8204.

Granolithic Screeding Kempston
is an extremely popular flooring material that's widely used in heavy-duty environments due to its strength and durability. It is 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 to an even, level surface.
The resulting flooring is slip-resistant, easy to clean and hard-wearing, making it ideal for use in areas with high foot traffic, such as schools, shopping centres and factories.
The granolithic screeding process involves preparation of the concrete sub-base, mixing the screed mixture, laying the mixture, and giving it time to cure. Appropriate application and curing techniques are crucial for the strength and longevity of the screed. The screed must be completely cured before any additional flooring products are laid.
When a floor's surface needs a degree of flexibility, it may be best to use a latex screeding. Latex floor screeds come in two parts - a bag and a bottle - with a bottle that contains liquid latex, and a bag that contains a cement powder. The liquid latex part takes the place of the water that's used in normal screeds, making it quicker drying and more flexible.
Prior to the laying of your chosen decorative surface, this latex product is used for levelling sub-floors. Suitable for subfloors of asphalt, wood, stone tiles, sand/cement and concrete, this gives a perfect surface for the application of adhesives that is smooth and resilient. If there happens to be a bit of movement in the subfloor this latex floor screed will produce a flexible, crack-free finish on which you can lay your final floor coverings.
When using a "floating" screed, for instance when screed is being laid on top of underfloor heating, depths of 50-75mm may be required, and latex floor screeds aren't a suitable choice in this case.
Multi-Coloured Floor Screeds
In commercial or industrial settings, multi-coloured screeds are frequently utilised as a flooring material. The unique and distinctive finish of these screeds is achieved by mixing coloured resins, aggregates, and sealants together. Due to their slip resistance and durability, they are frequently employed in areas with heavy foot traffic or machinery.
To match the brand of a business or create a specific aesthetic in a space,can be customised. Their easy-to-clean and maintain properties make them a favoured option for facilities that require a high standard of hygiene. Multi-coloured screeds' ability to provide a seamless finish that eliminates joints or grout lines makes them a perfect choice for cleanroom environments. All in all, coloured screeds provide both practicality and versatility as a flooring solution, making them a great option to add function and style to any industrial or commercial space.
What Does Screeding Do?
