Floor Screeding Sidcup Greater London (DA14): When faced with property or basement renovation, the challenge of a damaged or uneven floor, or the consideration of underfloor heating installation in your Sidcup home, it is vital to seek the guidance of an experienced floor screeding expert. The primary aim of screeding is to establish a seamless and even surface above a concrete sub-base, establishing a sturdy foundation for your selected flooring material. This necessary technique delivers a resilient and excellent finish for the whole floor structure, securing its durability and endurance. Engaging the services of a floor screeding professional guarantees a seamless and long-lasting floor surface that is tailor-made to meet your specific needs.
FLOOR SCREEDING COMPANIES SIDCUP
Supplying the experience and correct working methods to establish the perfect base for your floors, a floor screeding specialist in Sidcup can assist you with whatever size or shape of room or area you are remodeling. After a thorough evaluation of your screeding project, they will be able to advise you on which method of laying is best suited to your situation, and what is the perfect choice of screed to use.
They will in addition assess if a structural engineer is necessary to make certain that any flex strength, point loadings and load requirements are followed in accordance with construction and building regulations.
The skills and training that a qualified screeding contractor brings to your project should guarantee a high quality result and help in extending the lifespan of your floors. Choosing the appropriate screeding materials and the best installation technique is critical if you want a quality and durable finish for your floor.
Make sure you get at least two or three quotes for your Sidcup based screeding project and also ask what standard of finish each quote is for. For residential homes a quotation will generally be provided for an SR (Surface Regularity) standard of SR1 or SR2. SR2 and SR3 might be less expensive options, however the finished floor surface could have errors and deviations, whilst SR1 guarantees a perfect quality of finish. An SR2 or SR3 level might mean there are flat spots or ridges that could cause issues when installing your final flooring surface (carpet, tile, wood etc).
The regulations and guidelines specified in the British Standards BS8204 must be observed by all Sidcup floor screeding contractors and they should also hold accreditation with the manufacturers of specialist screeding materials (Cemfloor, Gypsol, Flowcrete etc.) to substantiate their competence and safe working practices. The training and assessment of a floor screeding contractor by such manufacturers is emphasised by the use of this accreditation scheme, and offers assurances of reliability and safe working practices on any flooring project involving their materials.
For larger screeding projects in factories, salons, warehouses, schools, hospitals and shopping centres, dedicated Sidcup commercial screeders will be needed.
TYPES OF SCREED
Standard Screeds - A combination of cement and sand which is okay for regular domestic usage. 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 1mm per day.
Industrial and Heavy Duty Screed - A screed designed for heavy traffic and high load areas where maximum durability and strength is essential.
Polymer Screeds - A high strength flooring solution where a reduced screed thickness is required. Polymer screeds are available from many screed manufacturers and because of their varying chemical compositions have specific setting times for each individual product.
Fibre Reinforced Screed - Used with under floor heating and is the suggested option in these projects. The fibres in this screed enhance it's durability and strength whilst also protecting against thermal cracking and shrinkage. It's got a drying rate of one millimetre per day.
Fast Drying and Advanced Drying Screeds - If you have to use the area in question as soon as possible a fast drying screed might be a good choice. The vast majority of the fast drying screeds are of the fibre reinforced kind and are suitable for a whole host of flooring projects where the quicker curing rate of 3-7mm/day is a considerable advantage.
Liquid or Self-Levelling Screeds - When the highest possible standard of finish is necessary this solution of cement and latex is employed to produce SR1 quality screed flooring. This is primarily used to provide a high quality floor over the top of a damaged or poor quality substrate and enables all types of flooring materials to be used. These can be as little as 1mm in depth, and thanks to the latex polymers, will still provide high strength.
SCREEDING PREPARATION AND INSTALLATION
Preparation is essential for a quality finished screed surface that will be durable and hard wearing. It's important that any contaminants such as grease, debris, paint or oil is eliminated from the base before laying any screed, as these can affect the adhesion capability that a quality screed demands.
Any cleansing products used in this phase should leave no residues, and the floor surface must be allowed to dry out naturally. It's essential to repair any cracks in the floor surface to avoid them being visible and "travelling" up into your newly screeded floor. During an on-site survey the screeding contractor will establish what preparation work is needed before any actual screeding work begins.
A damp proof membrane (DPM) will be applied once the preparation work has been finished to prevent ground dampness getting into the screeding and floor materials. There could be two or three layers of different thickness polythene to act as barriers between the screed and the insulation layer.
If your property is located in a place where radon is present an extra barrier layer is necessary to prevent radon gas from seeping through. If radon gas is present in severe doses then a full extraction and ventilation system may be installed under the layer of screed which will extract any gases that might seep in from ground level.
As soon as the floor base has been prepared and all membranes installed, a primer or sealer is then applied. Sealers and primers help the bonding process and are special applications according to the type of screed that is being used. On account of their special nature, only trained screeders in Sidcup should be entrusted with using them correctly, safely and using equipment which is made for the task.
Underfloor heating can now be laid out, installed and checked before screeding is applied. Insulation panels can be positioned and the cables and heating pipes will be firmly fastened so that there is no movement while the screed is applied. When skillfully installed an under floor heating system is an excellent way to warm a room and decent quality screed retains its heat, generating an even heat right across the floor.
The screed can now be mixed and prepared in situ and spread onto the floor surface. Your screeding company will have given you guidance and advice on which screed type is best for your requirements, in line with your proposed use of the room area. After the application of the screed there'll be a minimum twenty four hours (for advanced and quick drying screeds) before you are able to walk upon the surface, and a 72 hrs minimum curing period before any floor covering installation. If you're laying heavy duty or standard screeds the drying time is longer and the manufacturer's guidelines must be followed in order to get the best finish to your floor.
As soon as the screeding has solidified it can be quality checked to determine the SR level. The test involves using a 2 metre long straight-edge laid down upon the floor surface and any deviations from true are calculated.
- SR1 - SR1 is the best specification and permits just three millimetres of disparity from the straight-edge.
- SR2 - The standard flooring in industrial and commercial builds is classed as SR2 and has a maximum possible deviation of 5 millimetres across the entire screed.
- SR3 - SR3 is basic utility standard where a perfect finish isn't required. This specification allows for a maximium deviation of 10 millimetres.
If your screeding has been laid with specific load bearing requirements in mind then a structural engineer will be necessary to perform tests. Using specialised equipment the engineer will establish the screeded surface strength and its suitability for use in a load bearing setting. The screed layer will be given what's known as a "drop hammer test" to determine flexibility and strength in different areas. Any screeding that has load bearing requirements must be approved by a certified structural engineer observing the British Standards BS8204 guidelines.

Multi-Coloured Floor Screeds
In commercial or industrial settings, coloured screeds are frequently utilised as a flooring material. To create a distinctive and decorative finish, coloured resins, aggregates, and sealers are blended together to form these screeds. They are commonly used in areas where there is machinery or heavy foot traffic, as they provide a slip-resistant and durable surface that can withstand constant wear and tear.
Coloured screeds can be tailored to match a business brand, or to create a particular visual effect in a space. Their easy-to-clean and maintain properties make them a preferred option for facilities that require a high standard of hygiene. All in all, multi-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.
Granolithic Screeding
Granolithic screeding is a process of creating an even and smooth surface for floor coverings like carpets or tiles. It involves mixing sand, cement, and aggregate such as marble or granite chips to form a mixture, which is then applied to a concrete base. The mixture is levelled with a straightedge to give it a smooth, seamless surface.
This technique is typically 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.
Granolithic screeding is typically applied over a concrete sub-base, and the surface is typically treated with a curing compound to make sure it sets properly. Once cured, it creates a seamless floor with a smooth, hard surface that is resistant to excessive wear. It is also highly resistant to water and chemicals, which makes it perfect for use in environments where there's a risk of spills or exposure to dangerous materials.
