There are a number ofcompanies in the Llantwit Major area so make sure you get multiple quotations for your project before selecting a contractor and know to what standard of finish it's for. The quotation may be based on what is known as the Surface Regularity, or SR figure. Each of the 3 SR levels provide different qualities of finish, with SR1 being the highest quality, with the smallest amount of deviation over the area. An SR2 or SR3 standard may mean there will be flat spots or ridges that may cause issues when installing your final flooring surface (carpet, tile, wood etc).
British Standards BS8204 lays down the regulations and guidelines that all Llantwit Major screeding installers is obliged to follow, and if applying specialist screeding solutions, (Cemfloor, Gypsol, Flowcrete etc), they must be certified by the manufacturers as being skilled and trained in their use. The training and testing of a floor screeding contractor by such manufacturers is emphasised through the accreditation scheme, and gives assurances of safe working practices and reliability on any screeding project involving their materials.

TYPES OF SCREED
Standard Screeds - A mix of sand and cement which is ideal for standard residential use. The standard screed is a mix of five parts sand to one of cement. After laying a standard screed sets at a rate of just 1mm/day.
Polymer Screeds - These provide a high level of strength with a reduced thickness. Manufacturer's guidelines for setting times differ across the product ranges.
Fast Drying and Advanced Drying Screeds - If you have to press ahead urgently with the flooring due to time restraints, these screeds dry much faster than standard screeds. Drying at a rate of 3-7mm/day, depending on the specialised mix, they're typically ascreed and are suitable for projects that have tight schedules.
Industrial and Heavy Duty Screed - A screed that is designed for high load and heavy traffic areas where the maximum possible durability and strength is necessary.
Fibre Reinforced Screed - The expert's choice for domestic use over the top of under floor heating. The fibres in this screed mix increase it's durability and strength whilst also protecting against thermal cracking and shrinkage. It has a drying rate of 1mm per day.
Self-Levelling or Liquid Screeds - Used to produce the highest quality of finish, especially where SR1 levels are needed, by a latex and cement formula. The self-levelling compound provides a smooth and clean surface over a damaged floor or rough substrate to enable all types of flooring materials to be laid. They can be as little as one millimetre in depth, and due to the latex polymers, will still provide high strength.
SCREEDING PREPARATION AND INSTALLATION
Screeding companies will need to prepare the area before any other work in order to ensure a high quality and hard wearing screed flooring. Any paint, oil, grease and debris on the existing floor surface can affect the adhesion of the screed, and must be removed.
If cleansing products were used it's important to remove any traces of detergent, soap etc, and allow the surface to dry naturally. If screeding over a stone or cement floor all cracks should be repaired to stop them from "travelling" up through a screed layer and producing deviations on the finished floor surface. An on-site survey will allow the screeding contractor to pinpoint this preparation work and tackle it before commencing to pour the screeding.
Before any screeding can be poured a DPM (damp proof membrane) must be put down to protect the screed and final flooring from moisture damage. The DPM is made from thick polythene sheeting and various layers might be used to act as a moisture barrier and air insulating layer for the screed.
If your home is located in an area where radon gas is present an additional barrier layer is needed to stop radon gas from entering. An air-tight membrane could be enough in locations with relatively low radon emissions, but in more serious cases there might have to be a more complicated ventilation and extraction system to remove any harmful radon.
As soon as these stages have been completed the screeders will put on a sealant or primer to the prepared base. These primers and sealers will make certain that the screed bonds effectively to the base and help to accomplish a good quality finished floor. Devices such as airless sprays will usually be used to apply a primer or sealant, by professional screeding contractors in Llantwit Major sticking to the manufacturer's guidelines.
If you are going to be installing under floor heating, now is the time that it will need to be correctly set out and installed. The cabling and heating pipes are securely mounted on insulation panels to stop any movement and make certain that they are laid in the correct position. Underfloor heating is one of the most effective ways to heat a room and an expertly installed system will give an even level of warmth all over the floor.
The screeding can now be mixed and prepared on site and spread onto the base. Your screeding company will have given you advice on which type of screed is suitable for your requirements, according to your intended use of the room. Don't forget that even advanced and quick drying screeds have a minimum of 24 hours before you can walk over any laid surfaces and at least three days before any floor coverings can be applied. If you are looking to end up with a well finished and long-lasting floor surface you should stick to the manufacturer's guidelines with regard to standard and heavy duty screeds where this time period will be increased.
As soon as the screed has hardened it can be quality checked to verify its SR standard. Through the use of a two metre straight-edge the floor surface is examined for any deviations, dips and ridges in the surface of the screed.
- SR1 - SR1 is the best standard and permits just 3 millimetres of deviation from the straight-edge.
- SR2 - If the screeded floor has a deviation from the straight-edge of 5 millimetres or less it is classified as SR2 level and is the normal standard for commercial and industrial projects.
- SR3 - For utility floors where the finish is comparatively inconsequential the SR3 is the classification and has a maximum deviation measurement of 10mm or less.
There may also be a requirement for a qualified structural engineer to carry out a soundness test. Using specialist equipment the engineer will ascertain the screed surface strength and its suitability for use in a load bearing setting. This will include what's known as a drop hammer test which records specific data on the flexibility and strength of the screed. Only trained structural engineers respecting the BS8204 guidelines are permitted to conduct these testing and sign off on the structural safety of screed flooring.

Improving the strength and durability of concrete screeds can be achieved by using. A base layer is covered with thin and flat layers of concrete, called screeds, to create a level surface. Their typical application in construction projects is as flooring, although they can also be used as a finishing layer for walls and ceilings.
In order to improve strength and prevent cracking, the screed mixture is enriched with reinforcement materials such as wire, steel mesh or polypropylene fibres during installation. The reinforcement helps the surface to evenly distribute weight and load, as well as improve its ability to resist thermal changes, impact and abrasion.
The reinforcement of screeds decreases the risk of shrinkage and cracking caused by temperature or humidity changes, in addition to increasing their durability and strength. The kind of reinforcement material used may vary depending on the particular requirements of the project, and can be selected based on factors such as load capacity, finish and thickness. Consistent distribution of the reinforcement throughout the screed, and avoiding displacement over time, is crucial and depends on its correct installation. The structural integrity and quality of screeds can be maintained by using screed reinforcement, ensuring a long-lasting and reliable surface for various applications.
Latex Screed Llantwit Major
When the make-up of your floor's surface means that a certain amount of flexibility is required, it may be advantageous to apply a latex self-levelling floor screed, as opposed to one with an unyielding finish. Normally coming in 2 parts, latex screeds comprise a cementitious powder and a latex liquid component. The latex liquid additive replaces the water which would typically be used in a screed mix, and is far more flexible and quicker drying than other types of screed.
This latex screed compound is used to level-out a sub-floor before the final decorative surface is laid. This screed is suitable for substrate made of asphalt, quarry tiles, sand/cement, wood or concrete, is ideal for the application of flooring adhesives and gives a smooth and resilient surface. This latex floor screed will provide a flexible, crack-free finish, even if there happens to be movement in your sub-floor.
When an unbonded screed is being laid over a membrane of either acoustic or thermal insulation (i.e. a "floating" screed), latex flooring screeds are not a suitable choice, because in cases like this (typically when screeding on top of underfloor heating), you'll probably need a screed thickness of 50 to 65 millimetres.
