There are many different types of floor screeding and choosing the appropriate mix and laying technique is essential to create a high quality floor which is fit for purpose and hard-wearing.

TYPES OF SCREED
Standard Screeds - This is ideal for standard residential usage and is a blend of cement and sand. This mix comprises a 5:1 ratio of sand to cement. The standard flooring screed dries at a rate of one millimetre thickness per day.
Fast Drying and Advanced Drying Screeds - If you need to press ahead urgently with the work due to time constraints, this screed dries much quicker than standard screeds. The majority of the fast drying screeds are of the fibre reinforced kind and are suitable for a wide variety of flooring projects where the faster drying rate of 3-7mm/day is a big advantage.
Polymer Screeds - An extremely high strength solution where a reduced screed thickness is required. The curing times vary in accordance with product guidelines.
Industrial and Heavy Duty Screed - Where levels of traffic are expected to be high or heavy loading of the floor is required, heavy duty screeds deliver maximum durability and strength.
Fibre Reinforced Screed - The preferred choice by professional screeders for use with underfloor heating systems. The fibres in the screed increase it's durability and strength while also safeguarding against thermal cracking and shrinkage. It dries out at the same rate as a standard screed, at about 1mm per day.
Self-Levelling or Liquid Screeds - A latex and cement formula which can produce the highest standard of finish to SR1 levels. Mainly used to improve a poor substrate level or damaged floor to enable the laying of a brand new flooring surface, such as tiles over it. This liquid screed can be laid to a depth of only one millimetre, but will still provide a high strength base for a selection of flooring finishes.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a good quality finish which is durable and hard wearing, time must be spent on fully preparing the area prior to any screed being laid. It's vital that any contaminants such as paint, grease, oil or debris is eradicated from the floor before pouring any screed, since these can affect the adhesion process that a good quality screed requires.
If any products are used during this stage it is crucial to ensure that no residues of detergents, soaps or other cleaning products are left on the floor surface and it's allowed to dry out naturally. It's essential to fix any cracks in the base to stop them being reflected and "travelling" up into the freshly screeded floor. A site survey will enable your Harrow screeding company to highlight this preparation work and complete it before commencing to pour the screeding.
A damp proof membrane (DPM) will be installed after the preparation work has been completed to prevent ground dampness affecting the screeding and floor materials. There might be two or three layers of different thickness polythene to act as barriers between the screed and the insulation layer.
If your home is located in a place where radon is present a supplementary barrier layer is necessary to prevent radon gas from entering. An air-tight membrane could be sufficient in places with low emissions of radon, but in more serious situations there might need to be a more complicated extraction system to remove any ground penetrating radon.
The final step of surface preparation is the spraying or painting of a sealant or primer. These primers and sealers will make sure that the screed bonds perfectly to the base and help to accomplish a high quality finished floor. Because of their special nature, only certified screeding contractors in Harrow should be entrusted with using them safely and correctly and through the use of bespoke equipment for the task.
If you are going to be installing under floor heating, this is the time that it will need to be correctly laid out and installed. The underfloor heating system will be carefully positioned and firmly attached to insulation panels to avoid any movement in the course of the screed installation process. Warmth is spread evenly across a floor area in a professionally fitted underfloor heating system, and in conjunction with it being an effective method of heating, it's a great choice for many Harrow home renovation projects.
Of course, if you're not installing under floor heating, you can just skip this step and apply the screeding. Your proposed use of the room will assist the screeding contractor on what sort of floor screed is appropriate for your requirements. Don't forget that even advanced and quick drying screeds have a minimum of 24 hours before you're able to walk on any screeded surfaces and a minimum three days before any flooring can be applied. Such timescales will be longer for standard and heavy duty screeds and the manufacture's product guidelines must be followed to produce the optimal finish and longevity of the floor.
You can assess the SR level of the finished screeding as soon as it is set enough to walk on. Using a 2 mtr straight-edge the floor surface is checked for any dips, ridges and deviations in the screed surface.
- SR1 - Over the entire screed area, if there aren't any disparities of more than three millimetres from the straight-edge, then you've got a top level SR1 standard surface.
- SR2 - If the floor surface has a deviation from the straight-edge of five millimetres or less it is SR2 level and is the standard for commercial and industrial floors.
- SR3 - SR3 is utility standard where a perfect quality finish is not required. This level allows for a maximium deviation depth of 10 millimetres.
If your screeding has been laid with specific load bearing requirements in mind then a structural engineer will be needed to conduct the tests. Using specialised equipment the engineer will ascertain the screeded surface strength and viability of use in a load bearing environment. The screed will be given a "drop hammer test" to measure flexibility and strength in distinct areas. The specialist testing and measurement tools required mean that this can only be undertaken by a certified structural engineer obeying the guidelines of BS8204.
