TYPES OF SCREED
Standard Screeds - A mix of cement and sand which is perfect for everyday residential usage. 5 parts sand to 1 part cement is the usual mix for standard screed. This 5:1 ratio standardwill dry out at a rate of one millimetre per day after application.
Fibre Reinforced Screed - The favourite choice of professional screeders for use in combination with under floor heating systems. This is because of the improved durability and protection against thermal cracking and shrinkage offered by the fibres within the screed mix. It sets at an identical rate to a standard screed of 1mm per day.
Industrial and Heavy Duty Screed - Where traffic levels are high or heavy loading on the floor is necessary,provide maximum strength and durability.
Self-Levelling or Liquid Screeds - Used to produce the highest quality of finish, especially where SR1 levels are essential, by a cement and latex material. Mainly used to finalise a poor substrate level or damaged floor in order to lay a brand new flooring surface, such as tiles on top of it. Even with a depth of only 1mm, thewithin the screed provide a high strength surface for a variety of uses.
Fast Drying and Advanced Drying Screeds - If you have to move forward urgently with the work due to time constraints, these screeds dry more speedily than standard flooring screeds. They're normally atype of screed that dries out at a rate of between 3-7mm per day and are employed in time critical projects.
Polymer Screeds - These provide a high level of strength with a minimal thickness. Manufacturer's guidelines for drying times vary across the product ranges.
SCREEDING PREPARATION AND INSTALLATION
Preparation is essential for a quality finishedthat will be durable and hard wearing. It's vital that any contaminants such as paint, grease, loose debris or oil is removed from the floor surface before pouring any screed, because these can affect the bonding capability that a good quality screed demands.
Any cleaning chemicals used during this stage shouldn't leave any residues, and the floor surface must be permitted to dry by itself naturally. At this stage any cracks need to be repaired because these can travel up through the newly laid screed and be reflected in the finished floor surface. During a site survey your London screeding contractor will notice what preparation work is needed before any actual screeding work begins.
Before the screeding can be laid a DPM (damp proof membrane) will have to be put down to protect the final flooring and screed from moisture damage. There may be two or three layers of different thickness polythene to act as barriers between the insulation layer and screed.
If the area is susceptible to radon then one additional barrier is essential to stop this harmful gas from entering from the ground. A simple airtightcould be enough in places with relatively low radon measurements, but in more severe situations there may need to be a more sophisticated ventilation and extraction system to block any harmful radon gas.
As soon as the floor base has been prepared and all membranes installed, a sealer or primer is then applied. Primers help the bonding process and are special applications matched to the type of screed that is being applied. These products require certifiedto apply them in the right proportions by using airless sprays and other tailor-made equipment.
Before the screeding is laid, any under floor heating will now be installed. The underfloor heating system is laid out in the correct pattern and secured firmly toto avoid potential movement during screed installation process. When properly installed an underfloor heating system is an effective way to warm up a room and decent quality screed will retain its heat, generating an even heat right across the floor surface.
Of course, if you're not installing underfloor heating, you simply ignore this stage and apply the screed. Your use of the room will assist the screeding specialist on what kind of screed is right for your requirements. Don't forget that even quick drying screeds have a minimum of twenty four hours before you can walk over any screeded surfaces and a minimum 72 hours before any flooring can be laid. If you are laying standard or heavy duty screeds the drying time is longer and you should follow the manufacturer's guidelines so as to get the best finish for your floor.
The SR standard of your screeding can be ascertained once it's hardened enough to be walked upon. Using a 2 mtr straight-edge the surface is examined for any ridges, dips and deviations in the screed surface.
- SR1 - SR1 is the highest specification and permits just 3mm of deviation from the straight-edge.
- SR2 - The normal standard flooring in commercial and industrial builds is normally SR2 and has a maximum possible deviation of five millimetres across the whole screed.
- SR3 - For a utility area or room where the finish is comparatively immaterial the SR3 is the specification and has a deviation measurement of ten millimetres or less.
If you require load bearing checks, a qualified structural engineer is required to perform the tests. This test will ascertain the overall strength of the screed and the viability for its proposed use. An assessment called the "drop hammer test" will be performed at various areas on the screed layer and the results documented. Any screed floor that's got load bearing requirements must be okayed by a trained structural engineer following the British Standards BS8204 guidelines.

What Does Screeding Do?
Screeding plays a vital role in achieving several important objectives in construction projects:
- Compatibility with Floor Finishes.
- Improving Thermal and Sound Insulation.
- Smoothing and Levelling.
- Surface Protection.
- Corrections to Subfloors.
- Support for Underfloor Heating Systems.
- Stability and Structural Integrity.
- The Even Distribution of Loads.
All in all, the importance of screeding lies in its ability to create a durable, level and stable floor surface. By ensuring a solid foundation, it supports the floor finish in maintaining its quality and aesthetics, and enduring the demands of day-to-day use over an extended period.
When a degree of flexibility is necessary in the surface of a floor you might find that using a latex self-levelling screeding will be advantageous. Latex floor screed comes in two parts, a bag and a bottle, with the bag containing a cemetitious powder, and the bottle containing a liquid latex. The latex liquid solution actually replaces the water that would typically be used in a screed mix, and is much more flexible and quicker drying than other types of screed.
This latex screed is used to level-out a sub-floor before the final decorative surface is installed. This screed is appropriate for substrate made of asphalt, concrete, sand/cement, quarry tiles or wood, is ideal for the application of adhesives and gives a smooth, resilient surface. This type of screed will produce a flexible, crack-free finish, even if there is movement in your sub-floor.
Latex screeds are not appropriate where a "floating" screed is required, for example when an unbonded screed is being laid over a layer of either acoustic or thermal insulation, such as might be the case when you are screeding over underfloor heating, and screed depths of 50-65mm may be necessary.
