Standard Screeds - This is okay for basic residential usage and is a blend of sand and cement. The standard screed is a mix of five parts sand to one of cement. After laying a standard flooring screed dries out at a rate of 1mm/day.

Fibre Reinforced Screed - Mostly used with underfloor heating systems and is the preferred choice in these projects. This is because of the increased strength and protection against thermal cracking and shrinkage offered by the fibres within the screed. It's got a setting rate of one millimetre per day.

Liquid or Self-Levelling Screeds - When a high standard of finish is needed this mixture of cement and latex is used to create SR1 quality floor screeding. It is primarily used to provide a smooth, clean floor over the top of a damaged or poor quality substrate and results in a finish onto which all kinds of flooring materials can be laid. Even with a thickness of just one millimetre, the latex polymers within the mixture provide a high strength screed for a wide range of uses.

Advanced Drying and Fast Drying Screeds - If there is a need to use the area as quickly as possible a fast drying screed may be used. Drying at a rate of 3-7mm, subject to the mixture, they're typically a fibre reinforced type of screed and are ideal for projects that have tight schedules.

Good preparation is vital for a top quality screed surface that will be hard wearing and durable. The original floor surface should be thoroughly cleaned to remove any grease, paint, oil and debris that might adversely affect the bond of the screeding.

If any cleaning products were used in this process it is important to make sure that no residues of soaps or other cleaning products are left on the surface and it is permitted to dry out naturally. It's essential to fix any crevices or cracks in the surface to prevent them being reflected and "travelling" up into the newly screeded floor. A trustworthy Knebworth screeding company will take note of such issues during a on-site survey and make certain all preparations are complete before applying the next stages of the floor screeding process.

Before the screeding can be laid a damp proof membrane (DPM) must be put down to shield the final flooring and screed from moisture damage. There might be 2 or 3 layers of different thicknesses of polythene to act as barriers between the insulation layer and screed.

If your property is situated in an area where radon is present an extra barrier layer is essential to stop radon gas from entering. A simple airtight membrane could be enough in areas with relatively low radon emissions, however in more extreme cases there might have to be a more complicated extraction system to take away any harmful radon gas.

The final step of surface preparation is the painting or spraying of a sealant or primer. A primer assists in the screed to bond successfully to the base and membranes and different types exist according to which kind of screed is being applied. These products require trained contractors to apply them in the right ratios by using airless sprays and other bespoke equipment.

If you are going to be installing underfloor heating, this is the time that it will need to be set out and installed. Insulation panels can be laid out and the cabling and heating pipes will be firmly mounted to prevent any movement while the screed is poured. Underfloor heating is one of the most effective ways to heat a room and a professionally installed system will provide even warmth all over the floor.

The screeding can now be prepared in situ and applied to the base. Your use of the room will help your screeding company on which type of screed is best for your needs. After the pouring of the screed there'll be at least 24 hours (for advanced and quick drying screeds) before you can walk over the surface, and a seventy two hours minimum drying time before the laying of any floor coverings. If you are laying standard or heavy duty screeds the drying time is increased and you must observe the manufacturer's guidelines in order to get the best possible finish for your floor.

You can check the SR standard of the finished screed as soon as it is hardened enough for walking on. The test involves the use of a 2 mtr long straight-edge laid down upon the surface and any variations from true are measured.

  • SR1 - Disparities of 3 millimetres or less as measured across the entire floor area shows your screeding to be of the highest quality and classed as SR1.
  • SR2 - SR2 is for normal standard floors in industrial and commercial projects and can deviate from the straight-edge by up to five millimetres.
  • SR3 - SR3 is utility standard where a perfect quality finish is not required. This level 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. Using specialised equipment the structural engineer will ascertain the screeded surface strength and its suitability for use in a load bearing environment. An assessment called the "drop hammer test" will be carried out at various areas on the screed and the outcomes noted. The specialist measurement and testing tools involved mean this can only be performed by a trained structural engineer applying the guidelines of BS8204.
