FLOOR SCREEDING CONTRACTORS RAYNES PARK
Whatever size or shape of room or area you're remodeling, a decent floor screeding firm in Raynes Park can provide you with the expertise and proper working practices to generate a perfect base for your floors. They'll be ready to advise you on the right sort of screed your project requires, and the best methods for applying and installing it.
The screeding contractor will also let you know if a structural engineer is required for your undertaking, in order to evaluate any flex strength, load bearing and point loadings that your flooring might require to conform with British Standards and building regulations.
A skilled and qualified work force is essential to a successful outcome and will extend the life of your floor through the use of the correct sort of screed for the proposed purpose of your room. Selecting the correct screeding materials and the best installation technique is critical if you want to finish up with a quality and durable finish for your floor.
There are a number of screeding contractors in the Raynes Park area so if possible get multiple estimates for your project before picking out a contractor and know to what standard of finish is it for. The quote may be based on what is known as the SR, or Surface Regularity figure. SR2 and SR3 might be more affordable options, however the floor screeding finish could have errors and deviations, whilst SR1 guarantees a pretty much perfect quality of finish. An SR2 or SR3 standard could mean there are flat spots or ridges that may cause problems when laying your final flooring surface (tile, carpet, wood etc).
The regulations laid down in the British Standards BS8204 must be followed by all Raynes Park floor screeding contractors and they must also hold accreditation with the manufacturers of any specialist screeding materials (Cemfloor, Flowcrete, Gypsol etc.) to verify their competence and safe working practices. This accreditation scheme illustrates a company's high quality performance and training in the use of a manufacturer's screeding products.
Raynes Park commercial screeders will be involved in the screeding of floors in shopping centres, factories, pubs, schools, warehouses and hospitals.
TYPES OF SCREED
Standard Screeds - Frequently used in residential projects where the combination of cement and sand is acceptable for basic footfall use. The standard screed is a mixture of five parts sand to one of cement. After laying a standard flooring screed sets at a rate of just 1mm/day.
Self-Levelling or Liquid Screeds - A cement and latex material which can produce the highest standard of finish to SR1 levels. Mainly used to finish off a damaged floor or poor substrate level in order to lay a new flooring surface, like vinyl planks on top of it. The liquid screed can be laid to a depth of only 1mm, but will still provide a strong surface to take a wide range of flooring finishes.
Fast Drying and Advanced Drying Screeds - If you have to use the area in question ASAP a fast drying screed can be used. They are typically a fibre reinforced type of screed that dries out at a rate of between 3-7mm per day and are employed in time critical projects.
Fibre Reinforced Screed - The first choice where under floor heating is being installed in residential homes in Raynes Park. The improved flexibility and strength provided by the fibres in the screed help protect the floor from cracking and shrinkage due to heat. At roughly 1mm per day, it has an identical drying rate to standard screed.
Industrial and Heavy Duty Screed - Where levels of traffic are expected to be high or heavy loading of the floor is needed, heavy duty screeds offer maximum durability and strength.
Polymer Screeds - A high strength solution where a reduced screed thickness is required. On account of their different chemical compositions, these screeds have varying drying times which you can verify by studying manufacturer's product guidelines.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is essential for a quality finished screed surface that will be durable and hard wearing. The original floor surface should be cleaned to remove any debris, paint, grease and oil which can adversely affect the bond of the screed.
Any cleaning chemicals which are used during this stage should leave no residues, and the floor base must be allowed to dry out naturally. If screeding over a cement or stone floor then all cracks should be repaired to stop them from "travelling" through the screed layer and producing imperfections on the final surface. During an on-site survey your Raynes Park screeding contractor will ascertain what preparations are required before any actual screeding work commences.
A DPM (damp proof membrane) will be put down once the preparation work has been concluded to prevent ground dampness affecting the screeding and floor materials. There may be two or three layers of varying thicknesses of polythene to act as barriers between the insulation layer and screed.
If the area where you live is at risk from radon then a further barrier is essential to prevent the gas from entering via the ground. A simple air-tight membrane might be sufficient in locations with relatively low levels of radon, however in more extreme cases there might need to be a more complex ventilation and extraction system to take away any harmful radon.
As soon as these steps have been taken the screeding company will apply a sealer or primer to the prepared base. These primers and sealers will make certain the screed bonds successfully to the floor base and help to create a high quality finished floor. Owing to their specialist nature, only trained screeding contractors in Raynes Park are capable of using them correctly, safely and through the use of equipment that's made for the task.
Before the screeding can be poured, any under floor heating will now be installed. The under floor heating system will be carefully positioned and secured firmly to insulation panels to prevent potential movement during screed installation process. Under floor heating is one of the most efficient ways to heat a room and a skillfully installed system should give an even level of warmth all over the floor.
If you are not putting in under floor heating the screed will now be mixed and prepared in situ and poured. Your screeding contractor will give you guidance and advice on which type of screed is suitable for your needs, in line with your proposed use of the room area. Don't forget that even advanced and quick drying screeds have a minimum of twenty four hours before you're able to walk on any laid surface and at least 72 hours before any floor coverings can be laid. If you're aiming to end up with a properly finished and long-lasting floor surface you should follow the manufacturer's guidelines with regard to standard and heavy duty screeds where this waiting period will be longer.
The SR level of your screed can be confirmed once it has set enough to be walked upon. The basic SR test uses a 2 mtr long straight-edge to check for any fluctuations in the screed surface.
- SR1 - SR1 is the best standard and permits just 3 millimetres of deviation from the straight-edge.
- SR2 - The normal standard flooring in industrial and commercial builds is normally SR2 and has a maximum deviation of 5mm across the whole floor surface.
- SR3 - SR3 is utility standard where a quality finish isn't required. This classification allows for a maximium deviation depth of 10mm.
If your screeding has been laid with particular loading in mind then a qualified structural engineer will be required to carry out the tests. The assessment will make certain that your new screeding is viable for the load bearing requirements specified in the site survey. This will include what's known as a "drop hammer test" which assesses various aspects of the flexibility and strength of the screed. Any screed floor that's got point load requirements must be okayed by a qualified structural engineer respecting the British Standards BS8204 guidelines.

Screed Reinforcement
Screed reinforcement improves the strength and durability of concrete screeds by reinforcing them. A base layer is covered with thin and flat layers of concrete, called screeds, to create a level surface. Flooring is a common use for them in building projects, but they can also be used as a finishing layer for walls and ceilings.
In order to increase strength and prevent cracking, the screed mixture is enriched with reinforcement materials such as fibres, steel mesh or wire during installation. By distributing load and weight evenly across the surface, reinforcement improves its resistance to abrasion, thermal changes and impact.
In addition to increasing the durability and strength of screeds, the reinforcement process decreases the likelihood of cracking and shrinkage caused by changes in humidity or temperature. The structural integrity and quality of screeds can be maintained through the use of screed reinforcement, ensuring a reliable and long-lasting surface for a range of applications.
Latex Floor Screeds Raynes Park
When the characteristics of your floor's surface means that a bit of flexibility is needed, it will be advantageous to apply a latex screed, as opposed to one with a rigid finish. Latex floor screed comes in 2 parts, a bottle and a bag, with the bag containing a cement based compound, and the bottle containing a liquid latex. Latex screeds are more flexible and quicker drying than standard screeds, since the water which is normally used is replaced with the liquid latex.
This latex screed is used to level-out a sub-floor before the final decorative surface is laid. This is suitable for subfloors made from quarry tiles, sand/cement, wood, asphalt or concrete, is perfect for the application of adhesives and gives a smooth, resilient surface. If your subfloor has any movement in it, this type of latex screeding will still give you a flexible, crack-free finish, upon which your chosen floor coverings can sit.
Latex floor screeds are not appropriate where "floating" screeds are needed, for instance when a screed is being laid over a layer of either thermal or acoustic insulation, such as could be the case when you're screeding on top of underfloor heating, and thicknesses of 50 to 75 millimetres may be needed.
Screed Floor Removal
Existing screed can be removed from a surface through the procedure of screed floor removal. Floor upgrades or refurbishments often call for this process to be carried out. Specialist equipment and techniques play a crucial role in breaking down and removing the screed layer effectively during the removal process. This enables the surface to be prepared for new flooring or other modifications. Ensuring efficiency and safety, contractors adept at screed removal undertake the secure elimination of the old screed, providing a fresh start for the floor, whether for design changes, upgrades or repairs.
