Floor Screeding Purton Wiltshire (SN5): A floor screeding professional can level a damaged or uneven floor, help with renovations or help to install underfloor heating on your Purton home or business premises, when needed. To provide a level base for your choice of top flooring material, a screed is used to produce a smooth floor surface on top of a bare concrete sub-base. To guarantee a high quality and durable finish to the whole floor surface, screeding is a vital process.
FLOOR SCREEDING EXPERTS PURTON
Supplying the expertise and correct working methods to establish the perfect base for your floors, a floor screeding company in Purton can assist you with whatever size or shape of room or area you are renovating. Once your flooring project has been thoroughly assessed, they will be in a position to advise you on the correct type of screed your project requires, and how best it can be installed.
A professional screeding company will also let you know if a structural engineer is necessary for your project, in order to evaluate flex strength, load requirements and point loadings that your flooring may require to conform with building regulations and British Standards.
The training and skills that a qualified screeding specialist brings to your project will guarantee a successful end result and help to extend the lifespan of your floors. There are many kinds of screed and selecting the appropriate mix and installation technique is crucial if you are to achieve a top quality floor that is durable and fit for purpose.
There are numerous screeding contractors in the Purton area so try to get multiple quotes for your project before selecting a contractor and know to what standard of finish is it for. The price quote should be based on what is known as the SR, or Surface Regularity figure. Each of the three SR levels offer different levels of finish, with SR1 offering the highest quality, with the least amount of deviation over the surface area. This means you may have to rectify any areas that might cause issues when laying your final flooring material.
The rules and regulations specified in the British Standards BS8204 have to be observed by all Purton floor screeding companies and they should also hold accreditation with the manufacturers of specialist screeding materials (Cemfloor, Flowcrete, Gypsol etc.) to demonstrate their safe working practices and competence. This accreditation program illustrates a firm's high quality performance and training in the usage of a manufacturer's screeding products.
Commercial screeders in Purton will generally tackle screeding projects in hospitals, restaurants, schools, warehouses, factories and shops.
TYPES OF SCREED
Standard Screeds - Frequently used in domestic projects where the mix of cement and sand is ideal for normal footfall usage. 5 parts sand to 1 part cement is the typical mixture for standard flooring screeds. The standard screed dries at a rate of one millimetre thickness each day.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading of the floor is required, heavy duty screeds provide maximum durability and strength.
Advanced Drying and Fast Drying Screeds - If there's a need to use the floor ASAP a fast drying screed may be used. Drying out at a rate of three to seven millimetres, subject to the specialised mix, they are normally a fibre reinforced type of screed and are great for projects which have tight deadlines.
Polymer Screeds - These provide a high level of strength with a minimal thickness. The drying times vary according to proprietary product guidelines.
Fibre Reinforced Screed - The professional's choice for domestic use over the top of under floor heating. The improved flexibility and strength provided by the special fibres in the screed help protect the floor from thermal shrinkage and cracking. It has a setting rate of one millimetre per day.
Self-Levelling or Liquid Screeds - When a high standard of finish is required this mix of of latex and cement is employed to produce SR1 quality screed flooring. This self-levelling compound provides a clean and smooth surface over a rough substrate or damaged floor to allow all flooring materials to be laid. Even with a thickness of 1mm, the latex polymers within the screed provide a high strength surface for a variety of uses.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is essential for a quality finished screed surface that will be hard wearing and durable. Any grease, paint, debris and oil on the existing floor surface can adversely affect the bonding of the screed, and must be removed.
If cleaning products were used it's crucial to remove any residues of soap or detergent, and allow the surface to dry naturally. If screeding over a cement or stone floor all cracks should be mended to stop them from "travelling" through your screed layer and resulting in deviations on the finished floor surface. During a site survey your Purton screeding specialist will be able to see what preparations are necessary before any actual screeding work begins.
Before the screeding can be laid a damp proof membrane (DPM) will have to be put down to shield the screed and final flooring from dampness. Different thicknesses of special polythene could be used as a damp proof membrane and also act as a barrier for the screed and any insulation material.
A further airtight barrier could be necessary if your property is in a location which is regarded as susceptible to radon gas. If radon is present in large amounts 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.
The final stage of the surface preparation process is the spraying or painting of a primer or sealant. A primer assists in the screed to bond to the base and different varieties exist based on which kind of screed is being applied. Due to their special nature, only trained screeding specialists in Purton should be entrusted with using them safely and correctly and using bespoke equipment for this task.
Under floor heating can now be laid out, installed and checked before screeding is poured. The underfloor heating system is laid out in the correct pattern and attached firmly to insulation panels to stop any movement during screed pouring. Warmth will be evenly spread across a floor area in a skillfully installed under floor heating system, and coupled with it being an effective method of heating, it's an ideal choice for many Purton home renovation projects.
Obviously, if you aren't installing underfloor heating, you can just skip this step and get on with applying the screed. Your screeding contractor will give you advice and guidance on which kind of screed is appropriate for your requirements, in line with your proposed use of the room area. After application of the screed there'll be a minimum twenty four hours (for advanced and quick drying screeds) before you're able to walk upon the surface, and a seventy two hour minimum curing period before the laying of any flooring materials. If you are hoping to end up with a well finished and hard-wearing floor surface you should stick to the manufacturer's guidelines with regard to standard and heavy duty screeds where the waiting period will be increased.
The SR standard of your screed can be ascertained once it's solidified enough to be stepped onto. Through the use of a two metre straight-edge the surface is examined for any ridges, dips and deviations in the surface of the screed.
- SR1 - Over the entire area, if there are no deviations greater than 3 millimetres from the straight-edge, you've got a top quality SR1 level surface.
- SR2 - SR2 is for standard floors in industrial and commercial projects and can deviate from the straight-edge by up to five millimetres.
- SR3 - If the deviation is ten millimetres or less the quality of the screeding is classed as SR3 and is suitable for utility and garage areas.
If you require load bearing checks, a structural engineer is required to conduct the tests. This test will determine the strength of the screed and its suitability for the proposed use. This can include what is known as a drop hammer test which records specific data on the flexibility and strength of the screed. The precise testing and measurement tools required mean this can only be performed by a trained structural engineer obeying the guidelines of the British Standards BS8204.

Granolithic Screeding Purton
Granolithic screeding is an extremely popular flooring material that's widely used in heavy-duty environments due to its durability and strength. It's made from a mixture of cement, aggregate, sand, and sometimes pigments, which are combined to make 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 abrasion and chemical resistance. The resulting surface is durable, easy to clean, 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 giving it time to cure. Proper application and curing techniques are essential for the longevity and strength of the screed. The screed must be completely cured before any further flooring materials are installed.
What Does Screeding Do?
There are several significant purposes that screeding serves in construction projects:
- Structural Integrity and Stability.
- Support for Underfloor Heating Systems.
- Compatibility with Floor Finishes.
- Load Distribution.
- Surface Protection.
- Smoothing and Levelling.
- Improving Thermal and Sound Insulation.
- Subfloor Corrections.
All in all, the vital role of screeding is to create a stable, durable and level floor surface. Its role is to secure a solid foundation for the floor finish, allowing it to maintain its aesthetics and quality, and endure the demands of day-to-day use over an extended period.
Latex Floor Screeds Purton
It is best to use a latex self-levelling floor screed when a degree of flexibility is required in a floor's surface. Typically coming in two parts, latex screeds comprise a cementitious powder and a latex liquid mixture. The latex liquid solution replaces the water that's used in normal screeds, meaning that it is quicker drying and more flexible.
This latex product is used for levelling sub-floors in advance of the laying of the final decorative covering. Suitable for sub-floors of sand/cement, asphalt, stone tiles, wood and concrete, this screeding gives a perfect surface for the application of flooring adhesives that is resilient and smooth. If your sub-floor has any movement in it, this type of screeding will produce a flexible, crack-free finish, on which your chosen floor coverings can sit.
When using a "floating" screed, i.e. when screed is being laid over the top of underfloor heating, thicknesses of 50mm-65mm may be needed, and latex screeds are not a suitable choice for this purpose.
Screed Floor Removal Purton
Extracting and disposing of the pre-existing screed from a surface is the essence of screed floor removal. When undertaking floor upgrades or refurbishments, it is often a necessary step. To successfully break down and remove the screed layer, specialised techniques and equipment are indispensable in the removal process. Preparation of the surface for new floor covering or other modifications becomes achievable through this. Professional contractors skilled in screed floor removal ensure the efficient and safe removal of the old screed, enabling a fresh start for the floor, whether it's for repairs, upgrades or changes in design.
