Qualified and skilled workers are necessary for a successful outcome and will extend the life of your floor by using the correct form offor the intended purpose of your room. A correct mix of screed and the way it is laid is also vital to ensure the final intergrity of your floor.
Before selecting acontractor from any based in the Sleaford area, ask to what standard of finish they're basing their quote, and also ensure you get multiple quotes. The quotation may be based on what is called the SR, or Surface Regularity number. Each of the 3 SR levels deliver different qualities of finish, with SR1 offering the highest quality, with the least amount of deviation over the area. This means you may have to fix any areas that may cause issues when putting down your final flooring solution.
All Sleaford screeding installers have to adhere to British Standards (BS8204) and should have accreditation from the manufacturers of screeding equipment and materials, for instance Flowcrete, Gypsol, Cemfloor. This accreditation program illustrates a company's training and high quality performance in the use of a manufacturer's products.
For larger floor screeding projects in pubs, hospitals, shops, warehouses, schools and factories, dedicated commercial screeders in Sleaford will be needed.
TYPES OF SCREED
Standard Screeds - A combination of sand and cement which is perfect for basic domestic usage. The standard screed is a mixture of five parts sand to one of cement. This 5 to 1 ratio standardwill dry out at a rate of just 1mm per day after application.
Polymer Screeds - A high strength flooring solution where a reduced thickness is necessary. Because of their different chemical compositions, these screeds have varying drying times which you can verify by reading manufacturer's product guidelines.
Fibre Reinforced Screed - The preferred option where underfloor heating is being installed in residential homes in Sleaford. The greater strength and flex offered by the fibres within the screed mix help protect the flooring from cracking and shrinkage due to heat. The screed will dry out at a rate of 1mm/day.
Self-Levelling or Liquid Screeds - When the highest possible standard of finish is necessary this mixture of latex and cement is employed to achieve SR1 level screed flooring. Primarily used to finalise a poor substrate level or damaged floor so as to lay a brand new flooring surface, such as tiling on top of it. The liquid screed can be poured to a thickness of only one millimetre, but still provides a strong surface to take a varied selection of flooring finishes.
Advanced Drying and Fast Drying Screeds - As the name would suggest, this screed dries quickly and allows you to use the floor area much sooner. These are normally atype of screed which can dry at a rate of between 3-7mm per day and are employed in time critical projects.
Industrial and Heavy Duty Screed - Designed for maximum strength and durability on floors where traffic is high or specific loading of the floor base is required.
SCREEDING PREPARATION AND INSTALLATION
Screeding companies will need to carefully prepare the area prior to any other work in order to ensure a hard wearing and quality screed flooring. The existing floor surface should be cleaned to eradicate any debris, paint, grease and oil that might adversely affect the adhesion of the screeding.
Any cleansing chemicals used in this process should leave no residues, and the floor surface must be allowed to dry out naturally. If screeding over a stone or cement floor any cracks should be repaired to stop them from "travelling" through the screed layer and producing deviations on the finished floor surface. A professional Sleaford screeding contractor will pick up on such aspects during a site survey and ensure all preparations are completed before moving on to the next steps in the screeding process.
A damp proof membrane (DPM) will be put down after the preparation work has been finished to stop ground moisture affecting the flooring materials and screeding. There could be two or three layers of different thickness polythene to act as a barrier between the screed and the insulation layer.
If the area where you live is susceptible to radon gas then a further barrier is necessary to stop the gas from entering from the ground. If radon gas occurs in large amounts then a complete ventilation system may be installed beneath 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 put on a sealant or primer to the prepared floor base. Primers help with the bonding process and are specialist applications according to the kind of screed being applied. Custom-made equipment such as airless sprays can be used to apply a sealant or primer, by certified screeding companies in Sleaford following the manufacturer's guidelines.
Underfloor heating can now be laid out, installed and tested before the screed is poured. Insulation panels will be laid out and the heating pipes and wires will be securely attached to prevent any movement whilst the screed is being poured. When professionally installed an under floor heating system is an excellent way to warm up a room and good quality screed retains its heat, creating an even level of warmth across the floor.
Needless to say, if you are not fitting underfloor heating, you can bypass this stage and apply the screed. Your use of the room will help your screeding company on what type of screed is perfect for your requirements. After the application of the screed there'll be a minimum 24 hours (for quick drying and advanced screeds) before you can walk on the surface, and a 72 hours minimum curing period for the laying of any floor coverings. Manufacturer's drying guidelines for standard and heavy duty screeds must be followed so as to achieve a quality finish and provide a stable and long lasting floor surface.
As soon as the screeding has solidified it can be checked for quality to verify its SR level. Through the use of a 2 mtr straight-edge the floor surface is checked for any ridges, dips and deviations in the screed surface.
- SR1 - Deviations of three millimetres or less being measured over the entire area shows your screed floor to be of the best quality and specified as SR1.
- SR2 - SR2 is the classification for standard industrial and commercial floors and can deviate from the straight-edge by as much as 5 millimetres.
- SR3 - If the deviation is ten millimetres or less the quality of the screeding is classified as SR3 and is suitable for garage and utility areas.
If your screed has been installed with specific loading in mind then a qualified structural engineer is going to be required to conduct the assessment. Using specialised equipment the engineer will verify the screed surface strength and suitability of use in a load bearing environment. The screed layer will be given a "drop hammer test" to assess flexibility and strength in various areas. Any screed flooring that has point load requirements must be approved by a fully qualified structural engineer observing the BS8204 regulations.

When a level of flexibility is required in the surface of a floor you may find that using a latex floor screed will be advantageous. Latex screeds normally comprise two parts - a cement-based compound, and a liquid latex additive. The water that is normally used in a screed mix is replaced by the latex liquid, making it more flexible than other types of screed, and quicker drying.
This latex product is used for levelling sub-floors prior to the installation of the final decorative covering. This is appropriate for use on substrate of sand/cement, concrete, quarry tiles, wood and asphalt, to give a resilient and smooth surface which is ideal for the application of flooring adhesives. If there's any movement in the sub-floor this type of latex floor screed will produce a crack-free, flexible finish on which to lay your final floor coverings.
When using a "floating" screed, for instance when screeding is being laid on top of underfloor heating, depths of 50mm-75mm may be necessary, and latex screeds aren't a suitable choice in this case.
Screed reinforcement improves the durability and strength of concrete screeds by reinforcing them. Screeds are created by applying flat and thin layers of concrete to a base layer, resulting in a level surface. While commonly used in construction projects for flooring, they can also be utilised as a finishing layer for ceilings and walls.
Screed mixture during installation is infused with reinforcement materials, such as steel mesh, wire or polypropylene fibres, to enhance strength and prevent cracking. The reinforcement improves the surface's ability to resist abrasion, impact and thermal changes, while also ensuring that weight and load are evenly distributed.
The consistent distribution of reinforcement throughout the screed and preventing displacement over time depend on its proper installation, which is essential. The use of screed reinforcement is essential for ensuring that screeds maintain their quality and structural integrity, providing a long-lasting and reliable surface for various applications.
is a popular flooring material that's widely used in heavy-duty environments due to its durability and strength. It's made from a mixture of sand, cement, aggregate, and sometimes pigments, which are combined to form a mortar-like mixture. The mixture is poured onto the floor and then smoothed out to a level surface.
This technique is frequently 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 perfect base for other flooring products.
The granolithic screeding process involves preparation of the concrete base, mixing the screed mixture, laying the mixture, and allowing it to cure. Correct 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.
