The training and skills that a screeding technician brings to your project should guarantee a successful outcome and help to prolong the lifetime of your floor or floors. There are many types of screeding and choosing the right mix and installation process is crucial if you are to create a top quality floor which is fit for purpose and long-lasting.

TYPES OF SCREED
Standard Screeds - This is acceptable for regular domestic use and comprises a blend of sand and cement. The standard screed is a mix of five parts sand to one of cement. Once its been laid this 5:1 ratio dries at a rate of one millimetre per day.
Liquid or Self-Levelling Screeds - When the highest possible standard of finish is needed this formula of latex and cement is used to achieve SR1 quality screeding. This is mainly used to produce a high quality floor over the top of a damaged or poor quality substrate and enables all types of flooring materials to be used. The liquid screed can be poured to a depth of only 1mm, but will still provide a high strength surface for a selection of flooring materials.
Advanced Drying and Fast Drying Screeds - If there's a need to progress urgently with the flooring because of time limitations, these screeds dry more speedily than standard screeds. They're generally ascreed that dries out at a rate of between three and seven millimetres per day and are employed in time critical projects.
Fibre Reinforced Screed - The preferred option for professional installers where under floor heating is being installed in domestic homes in Cheshunt. The increased flex and strength offered by the special fibres within the screed help protect the floor from thermal cracking and shrinkage. It dries at an identical rate to a standard screed, at about 1mm per day.
Industrial and Heavy Duty Screed - Where levels of traffic are expected to be high or heavy loading on the floor is required, heavy duty screeds deliver maximum strength and durability.
Polymer Screeds - An extremely high strength flooring solution where a reduced thickness is essential. The setting times for these vary according to proprietary product guidelines.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is crucial for a top quality screed surface that will be durable and hard wearing. It is important that any contaminants such as debris, oil, grease or paint is removed from the base before pouring any screed, since these can affect the adhesion capability that a good quality floor screed needs.
If any products are used during this stage it's important to make sure that no residues of soaps or detergents are left on the floor surface and it is permitted to dry out naturally. If screeding over a stone or cement floor then all cracks should be mended to prevent them from "travelling" up through the screed layer and producing imperfections on the finished surface. A reliable Cheshunt screeding installer will pick up on such aspects during a site survey and ensure that all preparations are completed before moving on to the next stages of the screeding process.
To shield the flooring materials and screeding layer from moisture rising up through the ground, a damp proof membrane (DPM) must be laid. The damp proof membrane is made from thick polythene and different layers might be used to act as a moisture barrier for the screeding.
A supplementary air-tight barrier could be required if your building is in a location that is regarded as susceptible to radon. If radon is present in severe doses then a full ventilation and extraction system might be needed beneath the screed which will extract any gases that might seep in from ground level.
As soon as the base has been prepared and any DPMs installed, a primer or sealant is then put on. A primer assists in the screed bonding correctly to the base and different varieties exist based upon which screed type is being used. These materials need experienced tradesmen to apply them in the right ratios by using tailor-made equipment, such as airless sprays.
Underfloor heating can now be installed and checked before screeding is applied. Insulation panels will be put in place and the heating pipes and cabling will be securely mounted so there's no movement while the screed is being poured. Underfloor heating is one of the most efficient ways to heat a room and a properly installed system should give an even level of warmth in all areas of the floor.
If you're not putting in underfloor heating the screed will now be mixed and prepared on site and poured. Your proposed use of the room will help the screeding company on what sort of floor screed is best for your needs. After the pouring of the screed there is at least twenty four hours (for quick drying screeds) before you can walk on the surface, and a seventy two hour minimum curing time before the laying of any floor coverings. If you are laying standard or heavy duty screeds the drying time is longer and the manufacturer's guidelines must be adhered to so as to get the best possible finish to your floor.
The SR standard of your screeding can be ascertained once it's solidified sufficiently to be walked upon. Using a 2m straight-edge the floor surface is examined for any dips, deviations and ridges in the screed surface.
- SR1 - Over the whole screed area, if there aren't any disparities greater than 3mm from the straight-edge, then 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 deviation of 5 millimetres across the entire screeded surface.
- SR3 - For other floors where the finish is comparatively unimportant SR3 is the standard and has a deviation measurement of 10mm or less.
If you need to check the floor for load bearing, a structural engineer is required to perform the tests. This test will ascertain the overall strength of the screed and its suitability for the intended use. An assessment called the drop hammer test is performed on various areas of the screed layer and the outcomes recorded. Any screed flooring that has load bearing requirements must be okayed by a certified structural engineer following the BS8204 regulations.

Coloured Floor Screeds
In industrial or commercial settings, multi-coloured screeds are frequently utilised as a flooring material. A unique and decorative finish is created by combining coloured resins, aggregates, and sealants to form these screeds. Their durability and slip-resistant properties make them a popular choice for areas with machinery or heavy foot traffic.
By customising, a particular aesthetic can be achieved in a space or a business's branding can be matched. Their easy-to-maintain and clean properties make them a frequently chosen option for facilities that require a high standard of hygiene. In cleanrooms and similar environments, multi-coloured screeds' seamless finish, which eliminates grout lines or joints, makes them an excellent flooring choice. Furthermore, the aggregates used in coloured screeds can be selected based on their size, shape and colour to achieve a particular texture and pattern, giving architects and designers the freedom to create bespoke flooring designs that are tailored to their project requirements. Overall, the versatility and practicality of coloured floor screeds make them a flooring solution that can provide both style and function to any commercial or industrial space.
