Selecting the right screeding materials and the best installation technique is vital if you want to finish up with a durable and quality finish for your floor surface.

TYPES OF SCREED
Standard Screeds - This is acceptable for normal domestic use and is a combination of sand and cement. The standard screed is a mixture of five parts sand to one of cement. Once its been laid this 5:1 ratio dries at a rate of one millimetre per day.
Fibre Reinforced Screed - Used with underfloor heating and is the suggested option in such projects. This is because of the increased durability and protection against thermal cracking and shrinkage offered by the special fibres within the screed. It dries at the same rate as a standard screed, at about 1mm per day.
Advanced Drying and Fast Drying Screeds - If you need to move forward urgently with the work owing to time limitations, these screeds dry much faster than standard screeds. They're normally a fibre reinforced screed which can dry out at a rate of between 3-7mm per day and are used in time dependent flooring projects.
Industrial and Heavy Duty Screed - A screed designed for high load and heavy traffic areas where maximum durability and strength is crucial.
Polymer Screeds - Provides an extremely high level of strength with a minimal thickness. The drying times vary according to proprietary product guidelines.
Self-Levelling or Liquid Screeds - When the highest possible standard of finish is required this solution of cement and latex is used to create SR1 quality floor screeding. It's mostly needed to provide a high quality 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. The liquid screed can be poured to a depth of just 1mm, but will still provide a high strength base to take a wide variety of flooring materials.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to carefully prepare the area prior to any other work so as to ensure a high quality and hard wearing screed flooring. The original floor surface should be cleaned to remove any debris, oil, grease and paint which might adversely affect the bond of the screed.
If any cleaning products are used during this stage it's crucial to ensure that no residues of detergents or soaps are left on the surface and it is allowed to dry out naturally. At this point cracks need to be repaired since these can travel up through your laid screed and be visible in the completed surface. An on-site survey will enable your Hertford screeding company to take note of this preparation work and complete it before commencing to pour the screeding.
A damp proof membrane (DPM) will be put down once the preparation work has been completed to prevent ground dampness getting into the flooring materials and screed. The DPM is made of thick polythene and different layers may be used to act as a moisture barrier and air insulating layer for the screed.
If the area where you live is susceptible to radon gas then an additional barrier is essential to stop the gas from entering from the ground. A simple airtight membrane could be enough in places with low levels of radon, but in more extreme situations there might have to be a more sophisticated extraction and ventilation system to block any ground penetrating radon gas.
The final phase of the surface preparation process is the spraying or painting of a sealer or primer. A primer helps with the screed bonding process to the base and membranes and different types exist based upon which type of screed is being applied. On account of their specialist nature, only experienced screeders in Hertford are capable of using them safely and correctly and using equipment that's made for this task.
Under floor heating can now be installed and tested before screeding is applied. The heating pipes and cabling are securely mounted on insulation panels to prevent any movement and make sure that they're positioned correctly. Warmth will be evenly spread across the floor in a professionally installed under floor heating system, and with it being an efficient method of heating, it is a good choice for many Hertford renovation projects.
If you aren't fitting underfloor heating the screed will now be mixed and prepared on site and laid. The particular requirements of the room will dictate the form of screeding used. After the pouring of the screed there'll be at least twenty four hours (for quick drying screeds) before you can walk upon the surface, and a 72 hours minimum drying time for any floor covering installations. Such time periods will be longer for heavy duty and standard screeds and the manufacture's product guidelines must be followed to accomplish the optimal finish and longevity of the floor.
You can assess the SR standard of the completed screeding as soon as it is hard enough for walking on. Using a two metre straight-edge the floor surface is examined for any dips, ridges and deviations in the surface of the screed.
- SR1 - Over the whole floor area, if there are no deviations of more than 3 millimetres from the straight-edge, then you've got a top quality SR1 specification surface.
- SR2 - If the screeded floor has a deviation from the straight-edge of 5mm or less it is classified as SR2 level and is the normal standard for industrial and commercial floors.
- SR3 - If the deviation is 10mm or less the screed quality is classed as SR3 and is fine for garage and utility areas.
If you require load bearing checks, a qualified structural engineer is required to perform the tests. This test will establish the strength of the screeded surface and the suitability for its intended use. This will include what's known as a drop hammer test which records specific data on the flexibility and strength of the screed. Only experienced structural engineers respecting the BS8204 regulations are permitted to conduct these testing and sign off on the structural integrity of a screed floor.

Latex Screeds Hertford
When a floor's surface needs a certain degree of flexibility, it may be best to use a latex self-levelling screed. Typically coming in two parts, latex floor screeds comprise a cement-based powder, and a liquid latex component. The water that is normally used in a screed mix is replaced by the latex liquid, meaning it is more flexible than other types of screed, and quicker drying.
This latex screed product is used to level a subfloor before the final decorative surface is installed. This screeding is appropriate for use on sub-floors of concrete, asphalt, sand/cement, wood and stone tiles, to provide a durable, smooth surface that's ideal for the application of flooring adhesives. If there's a bit of movement in the sub-floor this type of latex screed will give you a flexible, crack-free finish on which to lay your chosen floor coverings.
With a "floating" screed, for example when an unbonded screed is being laid on top of a membrane of either acoustic or thermal insulation, latex floor screeds won't be a suitable choice. Floating screeds with a depth of 50 to 65 millimetres are usually used on top of underfloor heating.
