There are numerous types of floor screed and choosing the right mix and installation approach is vital to create a quality floor that is both fit for purpose and hard-wearing.

The SR (Surface Regularity) finish is the number to keep your eye on when receiving an estimate from your Ampthill screeding contractor.

TYPES OF SCREED
Standard Screeds - This is okay for standard residential usage and is a mix of cement and sand. The standard screed is a mix of 5 parts sand to one of cement. After laying a standard screed sets at a rate of just 1mm/day.
Fibre Reinforced Screed - The favoured option where underfloor heating is being installed in domestic properties in Ampthill. This is because of the increased strength and protection against thermal cracking and shrinkage offered by the special fibres within the screed mix. It sets at the same rate as a standard screed of one millimetre per day.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading on the floor is necessary,offer maximum durability and strength.
Liquid or Self-Levelling Screeds - Used to produce a high quality finish, especially where SR1 levels are necessary, by a latex and cement mixture. The self-levelling compound provides a smooth and level surface over a rough substrate or damaged floor to allow all kinds of flooring materials to be laid. The liquid screed can be laid to a thickness of only one millimetre, but still provides a high strength base to take a varied selection of flooring finishes.
Fast Drying and Advanced Drying Screeds - If there's a need to press ahead urgently with the flooring because of time limitations, these screeds dry much quicker than standard screeds. They are normally akind of screed that dries out at a rate of between 3-7mm per day and are used in time-sensitive flooring projects.
Polymer Screeds - Provides a high level of strength with a minimal thickness.are made by many manufacturers and due to their varying chemical compositions have specific curing times for each individual product.
SCREEDING PREPARATION AND INSTALLATION
To ensure that the screeding is of a good quality finish which is durable and hard wearing, time should be spent on carefully preparing the area before any screed is poured. The original floor surface should be cleaned to remove any oil, debris, grease and paint that might affect the bond of the screeding.
If cleansing products have been used it's vital to remove any traces of soap or detergent, and leave the floor surface to dry naturally. At this stage cracks need to be mended since these can travel up through the newly laid screed and be reflected in the finished floor surface. A decent Ampthill screeding company will take note of such issues during a on-site survey and make certain all preparations are completed before moving on to the next stages of the floor screeding process.
Before any screeding can be poured a DPM (damp proof membrane) must be put down to shield the screed and final flooring from dampness. The DPM is made out of thick polythene and various layers might be used to serve as a moisture barrier for the screeding.
If your house is located in a place where radon is found an extra barrier layer is needed to prevent radon gas from seeping through. An airtight membrane might be suitable in locations with relatively low levels of radon, but in more extreme situations there may need to be a more complicated ventilation and extraction system to remove any ground penetrating radon gas.
The final stage of surface preparation is the spraying or painting of a primer or sealer. These sealers and primers will guarantee the screed bonds perfectly to the base and help produce a top quality finished floor. These products require skilled tradesmen to apply them in the correct proportions by using airless sprays and other custom-made equipment.
Now is the time that underfloor heating can be laid out in the correct manner and installed. The underfloor heating system will be carefully positioned and secured firmly to insulation panels to avoid potential movement during screed pouring. Underfloor heating is one of the most efficient ways to heat a room and a professionally installed system should deliver even warmth across the floor area.
The screed can now be prepared on site and poured onto the base. The specific requirements of the room will dictate the type of screeding used. Remember that even quick drying screeds have a minimum of 24 hours before you're able to walk on any screeded surfaces and a minimum 3 days before any floor coverings can be laid. If you are looking to end up with a nicely finished and hard-wearing floor surface you must follow the manufacturer's guidelines with regard to heavy duty and standard screeds where the waiting period will be increased.
The SR standard of your screed can be checked once it's hardened sufficiently to be stepped onto. The test involves using a 2 mtr long straight-edge laid down upon the surface and any variations from true are calculated.
- SR1 - SR1 is the highest quality and permits just 3 millimetres of disparity from the straight-edge.
- SR2 - The standard flooring in commercial and industrial builds is normally SR2 and has a maximum deviation of five millimetres across the whole screed.
- SR3 - If the deviation around the whole space is ten millimetres or less the screed quality is classified as SR3 and is the standard required for utility and garage areas.
There might also be a requirement for a structural engineer to perform a soundness test. The assessment will ensure your new screed is viable for the load bearing requirements set down in the site survey. The screed layer could be subjected to what's known as a drop hammer test to measure strength and flexibility in different areas. Any screed floor that has point load requirements must be approved by a trained structural engineer heeding the British Standards BS8204 guidelines.

Latex Floor Screeds Ampthill
When the surface of a floor needs a degree of flexibility, it may be best to use a latex self-levelling screed. Latex floor screed comes in 2 parts, a bottle and a bag, with the bag containing a cemetitious powder, and a bottle that contains a liquid latex. Latex screeds are more flexible and quicker drying than standard screeds, because the water which is normally used is substituted with the liquid latex.
Used for levelling-out subfloors, this latex compound creates a surface for the installation of the final floor finish. This is suitable for use on substrate of asphalt, quarry tiles, sand/cement, concrete and wood, to give a resilient, smooth surface which is ideal for the application of flooring adhesives. This latex screed will give you a crack-free, flexible finish, even if there is a bit of movement in your subfloor.
When using a "floating" screed, for instance when screed is being laid over underfloor heating, depths of 50mm-65mm may be desirable, and latex floor screeds are not suitable for this purpose.
