TYPES OF SCREED
Standard Screeds - Frequently used in domestic projects where the blend of cement and sand is perfectly acceptable for normal floor traffic use. 5 parts sand to 1 part cement is the typical mix for standard screeds. Once laid this 5:1 ratio will dry at a rate of 1mm per day.
Polymer Screeds - When a reduced thickness of floor is necessary on account of construction requirements, a polymer screed offers an extremely high strength resolution to the problem. Polymer screeds are made by a number of screed manufacturers and on account of their diverse chemical compositions have specific curing times for each individual product.
Fast Drying and Advanced Drying Screeds - If there is a need to press ahead urgently with the flooring owing to time constraints, these screeds dry more speedily than standard screeds. The majority of the fast drying screeds are fibre reinforced and are suitable for a wide variety of flooring projects where the faster drying rate of 3-7mm/day is an advantage.
Fibre Reinforced Screed - The expert's choice for residential use on top of under floor heating. The increased flexibility and strength offered by the fibres in this screed help protect the resulting floor from cracking and shrinkage due to heat. It has a drying rate of one millimetre per day.
Self-Levelling or Liquid Screeds - When a high standard of finish is necessary this mix of of latex and cement is employed to create SR1 quality floor screeding. Primarily used to finalise a poor substrate level or damaged floor so as to lay a brand new flooring surface, like tiling on top of it. Even with a depth of just 1mm, the latex polymers within the mixture provide a high strength surface for a wide range of uses.
Industrial and Heavy Duty Screed - Where traffic levels are high or heavy loading on the floor is needed, heavy duty screeds provide maximum strength and durability.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to prepare all areas before any other work in order to ensure a hard wearing and quality screed flooring. The original floor surface should be cleaned to eradicate any paint, grease, oil and debris which might adversely affect the adhesion of the screeding.
If any products were used during this stage it's crucial to ensure that no residues of detergents, soaps or other cleaning products are left on the surface and it is allowed to dry out naturally. It is vital to mend any cracks in the base to stop them being visible and "travelling" upwards into your newly screeded floor. During an on-site survey your Northampton screeding installer will notice what preparations are necessary before starting to work on the screeding.
A damp proof membrane (DPM) will be put down once the preparation work has been completed to stop ground moisture affecting the flooring materials and screed. Different gauges of specialised polythene may be used as a DPM and also act as a barrier for the screed and any insulation material.
If the area is susceptible to radon gas then a further barrier is needed to stop the gas from entering via the ground. If radon is present in severe doses then a full ventilation and extraction system may be installed beneath the screed which will remove any gases that might seep in from ground level.
The final step of the surface preparation process is the spraying or painting of a primer or sealer. A primer helps with the screed bonding process to the base surface and different types exist based on which screed type is being applied. These products need skilled tradesmen to apply them in the appropriate ratios by using custom-made equipment, such as airless sprays.
This is the time that underfloor heating can be installed and laid out in the correct way. The under floor heating system will be carefully positioned and mounted firmly on insulation panels to stop any movement during screed application. When professionally installed an underfloor heating system is an effective way to warm up a room and decent quality screeding will retain its heat, generating an even level of warmth right across the floor surface.
The screed can now be mixed and prepared in situ and spread onto the floor base. Your screeding specialist will give you advice and guidance on which sort of screed is suitable for your needs, according to your intended use of the room. For quick drying and advanced screeds there will be at least 24 hours delay before it is able to be walked over, and a further Three days minimum before any flooring material can be applied. If you're laying standard or heavy duty screeds the setting time is longer and you should follow the manufacturer's guidelines so as to get the best finish to your floor.
The SR level of your screed can be confirmed once it has set enough to be stepped onto. The test involves the use of a 2 mtr long straight-edge laid on the floor surface and any fluctuations from true are calculated.
- SR1 - Over the entire floor area, if there aren't any disparities of more than 3 millimetres from the straight-edge, then you have a top quality SR1 specification surface.
- SR2 - If the floor has a deviation from the straight-edge of 5 millimetres or less it is classified as SR2 level and is the standard for commercial and industrial projects.
- SR3 - For other floors where the quality of finish is comparatively immaterial the SR3 is the classification and has a maximum deviation measurement of 10 millimetres or less.
If you need to check the screeded floor for load bearing, a qualified structural engineer is required to perform the testing. This test will determine the strength of the screeded surface and its suitability for the intended use. An assessment called the drop hammer test is carried out at several areas on the screed and the results noted. Only fully qualified structural engineers obeying the British Standards BS8204 guidelines are allowed to carry out these testing and sign off on the structural integrity of the screeding.

Latex Floor Screed Northampton
When the surface of a floor needs a certain amount of flexibility, it might be wise to use a latex screeding. Typically coming in two parts, latex floor screeds comprise a cement-based compound, and a liquid latex mixture. The latex liquid part actually replaces the water which would normally be used in a screed mix, and is quicker drying and far more flexible than other types of screed.
This latex compound is used for levelling-out sub-floors in advance of the laying of your chosen decorative surface. This screeding is suitable for use on subfloors of concrete, asphalt, sand/cement, wood and stone tiles, to provide a smooth, resilient surface that is perfect for the application of adhesives. If your subfloor has a bit of movement in it, this type of latex screed will give you a crack-free, flexible finish, on which your chosen floor coverings can sit.
When using a "floating" screed, for example when screed is being laid on the top of underfloor heating, depths of 50mm-65mm may be desirable, and latex screeds are not appropriate for this purpose.
