FLOOR SCREEDING EXPERTS PURTON
Having all the knowledge and experience to help you achieve a perfect floor in whichever size room you're working on, a decent floor screeding company in Purton is the ideal choice for your floor screeding project. After evaluating your project they will give you advice about the optimal choice of screed and which method of laying it is most suitable for your situation.
They will likewise assess if a structural engineer is needed to make sure that any flex strength, point loadings and load bearing are followed as set out in construction and building regulations.
Skilled and qualified tradesmen are essential to a successful result and will extend the life of your floor through the use of the correct kind of screed for the intended purpose of your room. Selecting the correct screeding materials and the best installation technique is crucial if you want a quality and durable finish for your floor.
Make sure that you get two or three estimates for your Purton based floor screeding project and also ask to what standard you are getting a quote. The estimate should be based on what is called the SR, or Surface Regularity figure. SR1 is the best standard, and whilst SR2 and SR3 might be less expensive at first glance, they don't guarantee a perfectly even or flat surface. This means you might have to fix any areas that might cause issues when laying your final flooring material.
British Standards BS8204 lays down the regulations and guidelines that all Purton screeding contractors must follow, and if applying specialist screeding solutions, (Cemfloor, Flowcrete, Gypsol etc), they should be certified by the manufacturers as being trained and skilled in their use. The training and assessment of a floor screeding contractor by a manufacturer is highlighted through the accreditation scheme, and guarantees safe working practices and reliability on any project involving their materials.
For the screeding of floors in restaurants, hospitals, shops, schools, factories and warehouses, skilled Purton commercial screeders will be required.
TYPES OF SCREED
Standard Screeds - This is ideal for basic domestic usage and comprises a mixture of cement and sand. 5 parts sand to 1 part cement is the usual mixture for standard screed. After laying a standard flooring screed dries out at a rate of 1mm/day.
Self-Levelling or Liquid Screeds - A cement and latex formula which can produce the highest standard SR1 finish. Primarily used to finish off a damaged floor or poor substrate level to enable the laying of a new flooring surface, like tiling on the top of it. These can be as little as one millimetre thick, and because of the latex polymers, will still provide a high strength finish.
Polymer Screeds - These provide an extremely high level of strength with a lower thickness. Manufacturer's guidelines for curing times differ across the various product ranges.
Fibre Reinforced Screed - Used with under floor heating systems and is the recommended choice in these projects. The greater flexibility and strength provided by the fibres within this screed help protect the resulting floor from thermal cracking and shrinkage. The screed will set hard at a rate of roughly 1mm/day.
Industrial and Heavy Duty Screed - Developed for maximum durability and strength on floors where traffic is high or specific loading of the floor base is required.
Advanced Drying and Fast Drying Screeds - As the name suggest, these screeds dry rapidly and allow you to use the floor area much sooner. Drying out at a rate of three to seven millimetres, depending on the mix, they are usually a fibre reinforced screed and are suitable for projects that have tight schedules.
SCREEDING PREPARATION AND INSTALLATION
Screeding companies will need to carefully prepare all areas before any other work so as to ensure a hard wearing and quality screed flooring. Any oil, grease, debris and paint on the existing floor level can adversely affect the bonding of the screed, and must be eliminated.
If any products were used in this process it's important to ensure that no residues of soaps, detergents or other cleaning products are left on the surface and it's permitted to dry out naturally. It is vital to repair any crevices or cracks in the surface to prevent them being mirrored and "travelling" upwards into your freshly screeded floor. A genuine Purton screeding contractor will address these aspects during a on-site survey and make sure all preparations are finished before moving on to the next steps in the screeding process.
To protect the screeding layer and flooring materials from dampness rising up through the ground, a damp proof membrane (DPM) must be installed. Different gauges of special polythene might be used as a damp proof membrane and also serve as a buffer for the screed and any insulation materials.
Another air-tight barrier might be required if your home or business premises is in an area which is regarded as susceptible to radon gas emissions. An air-tight membrane might be sufficient in places with relatively low radon emissions, however in more serious cases there might need to be a more complicated extraction and ventilation system to block any harmful radon gas.
The final stage of surface preparation is the spraying or painting of a sealer or primer. These sealers and primers will make sure the screed bonds successfully to the base surface and help to produce a high quality finished floor. Equipment such as airless sprays are used to apply a sealant or primer, which should be done by experienced screeding installers in Purton observing the manufacturer's guidelines.
Under floor heating can now be laid out, installed and tested before screeding is poured. The cabling and heating pipes are firmly mounted on insulation panels to prevent any movement and make sure that they are positioned correctly. Underfloor heating is one of the most effective ways to heat a room and a properly installed system should provide even warmth in all areas of the floor.
If you are not putting in under floor heating the screed can now be prepared on site and laid. Your screeding company will have given you advice on which screed type is best for your needs, according to your proposed use of the room area. After the pouring of the screed there is a minimum 24 hours (for quick drying and advanced screeds) before you can walk over the surface, and a 72 hour minimum drying time before the laying of any floor coverings. If you're hoping to end up with a well finished and durable floor surface you should stick to the manufacturer's guidelines with regards to standard and heavy duty screeds where this waiting period will be increased.
As soon as the screeding has hardened it can be quality checked to determine the SR standard. The basic SR test involves the use of a two metre long straight-edge to check for any variations in the screeded surface.
- SR1 - Deviations of three millimetres or less as measured over the whole area shows your screed floor to be of the finest quality and classified as SR1.
- SR2 - SR2 is the classification for normal standard industrial and commercial floors and can deviate from the straight-edge by up to five millimetres.
- SR3 - If the deviation around the room is 10mm or less the screed quality is categorised as SR3 and is suitable for garage and utility areas.
If your screed floor has been laid with specific loading in mind then a qualified structural engineer will be required to perform the tests. The assessment will ensure your newly laid screed surface is viable for the load bearing requirements set down in the original site survey. The screed could be subjected to a drop hammer test to gauge flexibility and strength in different areas. The precise measurement and testing tools required mean this can only be carried out by a qualified structural engineer applying the BS8204 guidelines.

Latex Floor Screeds Purton
When the surface of a floor needs a degree of flexibility, it is wise to use a latex floor screed. Typically coming in 2 parts, latex floor screeds comprise a cementitious powder and a liquid latex additive. Latex screeds are quicker drying and more flexible than standard screeds, as the water that's normally used is replaced with the latex liquid.
Before the laying of your chosen decorative surface, this latex compound is used for levelling-out subfloors. Producing a resilient and smooth surface that is perfect for the application of flooring adhesives, this is is appropriate for use on substrate of wood, quarry tiles, sand/cement, asphalt and concrete. This type of latex floor screed will produce a crack-free, flexible finish, even if there's movement in your subfloor.
When an unbonded screed is being laid on the top of a layer of either acoustic or thermal insulation (i.e. a floating screed), latex screeds aren't a suitable choice, because in this instance (generally when screeding on top of underfloor heating), you'll probably require a thickness of 50-65mm.
