Floor Screeding Nelson Lancashire (BB9): If you are looking to install underfloor heating, are restoring a property or cellar or have an uneven or damaged floor, then getting in touch with a specialist floor screeding service in Nelson is your best option. Before you can lay a suitable floor covering, whether it is tile, wood or carpet, the surface of the floor should be as flat as is possible; this is why floor screeding is often essential. To guarantee a high quality and durable finish to the whole floor surface, screed is an essential element.
FLOOR SCREEDING COMPANIES NELSON
Supplying the experience and correct working methods to generate a perfect base for your floor, a floor screeding company in Nelson can help you no matter what size or shape of room you're renovating. When your project has been carefully evaluated, they will be able to advise you on the appropriate type of screed required for your project, and how best it can be installed.
Your screeding company will also notify you if a structural engineer is needed for your undertaking, in order to check on point loadings, load bearing and flex strength that your flooring might need to conform with building regulations and British Standards.
A qualified and skilled work force is imperative for a successful outcome and will extend the life of your floor by using the correct type of screed for the proposed purpose of your room. There are many different kinds of screed and picking the right mix and laying technique is essential if you are to achieve a top quality floor that is fit for purpose and long-lasting.
Before choosing a floor screeding company from those based in the Nelson area, ask to what standard of finish they are basing their estimate, and also make certain that you get multiple quotations from different screeders. The quotation might be based on what's called the Surface Regularity, or SR calculation. Each of the 3 SR levels deliver different levels of finish, with SR1 being the highest quality, with the least amount of deviation over the surface area. Any errors in the screeding can cause issues with laying flooring due to flat spots, ridges, indentations in the floor surface.
British Standards BS8204 sets down the regulations and guidelines that all Nelson screeding installers must follow, and if working with specialist screeding solutions, (Cemfloor, Gypsol, Flowcrete etc), they must be approved by the manufacturers as being trained and skilled in their use. This accreditation program showcases a company's training and high quality performance in the use of a manufacturer's products.
Nelson commercial screeders may be involved in floor screeding in factories, schools, pubs, shopping centres, hospitals and warehouses.
TYPES OF SCREED
Standard Screeds - This is good for basic domestic use and is a combination of sand and cement. 5 parts sand to 1 part cement is the typical mix for standard screeds. This 5:1 ratio standard screed will set hard at a rate of one millimetre per day after application.
Fibre Reinforced Screed - Used with underfloor heating systems and is the preferred option in such projects. The special fibres in the screed enhance it's durability and strength whilst also safeguarding against thermal shrinkage and cracking. 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 create SR1 quality floor screeding. This is mainly used to produce a high quality floor over the top of a poor quality or damaged substrate and enables all types of flooring materials to be used. The liquid screed can be laid to a depth of only 1mm, but will still provide a high strength base to take a wide range of flooring finishes.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading on the floor is required, heavy duty screeds allow for maximum durability and strength.
Polymer Screeds - When a lower thickness of floor is necessary because of construction requirements, a polymer screed offers a high strength resolution to the problem. Because of their different chemical compositions, polymer screeds have varying curing times which can be verified by viewing manufacturer's product guidelines.
Advanced Drying and Fast Drying Screeds - If you need to use the area in question at the earliest opportunity a fast drying screed might be a good choice. The majority of the fast drying screeds are fibre reinforced and are perfect for a wide range of flooring projects where the swifter drying rate of three to seven millimetres is a big advantage.
SCREEDING PREPARATION AND INSTALLATION
To make sure the screeding is of a good quality finish that is durable and hard wearing, time must be spent on preparing the area before any screeding material is poured. It's crucial that any contaminants such as loose debris, paint, oil or grease is eradicated from the base before pouring any screed, since these can affect the adhesion capability that a quality floor screed requires.
Any cleaning products that are used during this process should leave no residues, and the floor base must be allowed to dry by itself naturally. At this point cracks should be mended as these can travel up through your laid screed and be reflected in the finished floor surface. A site survey will enable the screeding installer to take note of these preparation areas and finish them before starting to pour the screeding layer.
To protect the flooring materials and screeding layer from moisture rising up through the ground, a damp proof membrane (DPM) will have to be installed. There might be 2 or 3 layers of different thickness polythene to act as a barrier between the insulation layer and screed.
An additional airtight barrier might be needed if your building is in a location that is regarded as susceptible to radon gas. This could be as simple as an air-tight membrane, or in more serious instances an extraction and ventilation system will need to be installed under the screed to extract any inflow of air and gas from ground level.
As soon as these stages have been completed the screeders will apply a sealer or primer to the prepared floor base. These primers and sealers will ensure that the screed bonds perfectly to the base surface and help to produce a good quality finished floor. These substances require professional contractors to apply them in the appropriate proportions by using airless sprays and other bespoke equipment.
Underfloor heating can now be laid out, installed and checked before the screed is applied. The heating pipes and cabling are securely attached to insulation panels to prevent any movement and ensure that they're laid in the correct position. When expertly installed an under floor heating system is an effective way to warm up a room and high quality screeding will retain its heat, creating an even heat right across the floor.
Needless to say, if you are not installing underfloor heating, you can ignore this stage and apply the screeding. Your screeding specialist will have given you guidance and advice on which screed type is best for your needs, in line with your intended use of the room area. For advanced and quick drying screeds there will be at least 24 hours delay before it can be walked over, and a further Three days minimum before any flooring material can be laid over it. If you're aiming to wind up with a properly finished and durable floor surface you must stick to the manufacturer's guidelines with regard to heavy duty and standard screeds where this timescale will be increased.
The SR standard of your screed can be checked once it has solidified sufficiently to be stepped onto. The test involves using a 2m straight edge laid on the floor surface and any fluctuations from true are measured.
- SR1 - SR1 is the best level and allows just three millimetres of disparity from the straight-edge.
- SR2 - If the screeded surface has a deviation from the straight-edge of 5 millimetres or less it is classified as SR2 quality and is the standard for industrial and commercial floors.
- SR3 - For a utility area or room where the finish is comparatively immaterial the SR3 is the specification and has a maximum deviation measurement of ten millimetres or less.
It might also be necessary for a structural engineer to do a soundness test. Using specialist equipment the engineer will verify the screed surface strength and its suitability for use in a load bearing setting. The screed layer will be subjected to what is known as a "drop hammer test" to assess flexibility and strength in different areas. Only fully qualified structural engineers respecting the British Standards BS8204 regulations are allowed to perform these testing and sign off on the structural safety of screed flooring.

Latex Floor Screeds
When a bit of flexibility is needed in a floor's surface you might find that the employment of a latex screeding will be advantageous. A latex floor screed comes in 2 parts, a bag and a bottle, with the bag containing a cement based smoothing compound, and a bottle that contains a liquid latex. Latex screeds are more flexible and quicker drying than other types of screed, because the water which is normally used is exchanged for the liquid latex.
This latex product is used for levelling-out sub-floors in advance of the laying of your chosen decorative covering. This is suitable for sub-floors made from concrete, sand/cement, asphalt, stone tiles or wood, is ideal for the application of adhesives and gives a smooth, resilient surface. If your subfloor has any movement in it, this latex screed will still produce a crack-free, flexible finish, onto which your chosen floor coverings can be laid.
When a screed is being laid on the top of a membrane of either acoustic or thermal insulation (i.e. a "floating" screed), latex floor screeds are not appropriate, because in this case (normally when screeding over underfloor heating), you will likely require a thickness of 50 to 75 millimetres.
Screed Floor Removal
To remove a screed floor, one must extract and dispose of the pre-existing screed from the surface. A common requirement arises during floor upgrades or renovations. The removal process requires specialist techniques and equipment to successfully break down and remove the layer of screed. This enables the surface to be prepared for new flooring or other modifications. Expert contractors in screed floor removal meticulously eliminate the old screed, guaranteeing safety and efficiency, and allowing the floor to embark on a fresh journey, whether for upgrades, repairs or design changes.
