Fast Drying and Advanced Drying Screeds - If you have to move forward urgently with the flooring due to time restraints, these screeds dry more speedily than standard flooring screeds. The vast majority of the fast drying screeds are of the fibre reinforced kind and are suitable for a whole host of flooring projects where the speedier drying rate of 3-7mm is an advantage.

Polymer Screeds - These provide an extremely high level of strength with a minimal thickness. Manufacturer's guidelines for drying times vary across the product ranges.

Self-Levelling or Liquid Screeds - A cement and latex solution which can achieve the highest standard of finish to SR1 levels. Mostly used to finish off a poor substrate level or damaged floor so as to lay a new flooring surface, like tiles on top of it. These can be as little as 1mm thick, and because of the latex polymers, will still provide a high strength finish.

Fibre Reinforced Screed - The favoured choice by professional installers for use in combination with under floor heating systems. The fibres in the screed mix improve it's strength and durability while also safeguarding against thermal shrinkage and cracking. It has a drying rate of 1mm per day.

Industrial and Heavy Duty Screed - Where levels of traffic are high or heavy loading on the floor is needed, heavy duty screeds deliver maximum strength and durability.


Screeding companies will need to prepare all areas before any other work so as to ensure a hard wearing and quality screed flooring. It is crucial that any contaminants such as oil, loose debris, paint or grease is eradicated from the base before pouring any screed, as these can affect the bonding capability that a quality floor screed needs.

Any cleansing products that are used during this stage should leave no residues, and the floor surface must be allowed to dry by itself naturally. If screeding over a cement or stone floor then all cracks should be repaired to prevent them from "travelling" through the screed layer and resulting in deviations on the finished surface. A site survey will allow your Knaphill screeding specialist to highlight this preparation work and finish it before starting to pour the screeding.

To shield the flooring materials and screeding layer from dampness rising up through the ground, a DPM (damp proof membrane) must be laid. There might be 2 or 3 layers of varying thicknesses of polythene to act as barriers between the screed and the insulation layer.

If the area is susceptible to radon gas then an additional barrier is essential to stop the gas from entering from the ground. A simple air-tight membrane could be suitable in locations with low emissions of radon, however in more serious situations there might have to be a more complicated extraction system to remove any ground penetrating radon gases.

The final step of surface preparation is the painting or spraying of a sealant or primer. Sealers and primers help with the bonding process and are specialist applications according to the kind of screed being used. Devices such as airless sprays can be used to apply a primer or sealant, which should be done by professional screeding installers in Knaphill observing the manufacturer's guidelines and safety advice.

If required, this is the time that underfloor heating can be laid out in the correct manner and installed. Insulation panels can be laid out and the cables and heating pipes will be securely fastened so there's no movement while the screed is being applied. Underfloor heating is one of the most effective ways to heat a room and an expertly installed system should deliver even level of warmth in all areas of the floor.

If you're not fitting under floor heating the screed will now be prepared in situ and poured. The requirements of the room will dictate the sort of screeding that's used. For quick drying and advanced screeds there will be at least a twenty four hour delay before it is able to be walked over, and a further Three days minimum before you are able to lay any flooring materials. If you're laying standard or heavy duty screeds the curing time is longer and you should observe the manufacturer's guidelines in order to get the best finish to your floor.

Once the screed has hardened it can be checked for quality to verify its SR standard. The standard SR test uses a two metre straight edge to check for any variations in the screed surface.

  • SR1 - SR1 is the best level and allows only 3 millimetres of disparity from the straight-edge.
  • SR2 - If the screed has a deviation from the straight-edge of 5mm or less it is SR2 quality and is the standard for commercial and industrial floors.
  • SR3 - For other floors where the quality of finish is fairly inconsequential the SR3 is the specification and has a maximum deviation measurement of ten millimetres or less.

If your screed floor has been installed with particular loading in mind then a structural engineer is going to be necessary to conduct tests. The assessment will make sure that your new screeding is suitable for the load bearing requirements laid out in the site survey. This can include what's known as a drop hammer test which records specific data on the strength and flexibility of the screed. Any screed flooring that's got point load requirements must be sanctioned by a competent structural engineer observing the BS8204 regulations.

Screed Reinforcement

The technique for reinforcing concrete screeds using screed reinforcement is implemented to improve their strength and durability. Applying thin, flat layers of concrete to a base layer is the method used to create level surfaces, which are called screeds. Commonly, they are used in building projects as flooring, but they can also function as a finishing layer for walls and ceilings.

Floor Screed Reinforcement

Screed mixture during installation is infused with reinforcement materials, such as fibres, steel mesh or wire, to improve strength and prevent cracking. Reinforcement aids in the even distribution of weight and load on the surface, while also improving its resistance to abrasion, thermal changes and impact.

The consistent distribution of reinforcement throughout the screed and preventing displacement over time depend on its correct installation, which is essential. To make sure that their projects will provide a functional, high-quality surface for many years to come, screeding companies may use screed reinforcement.

Latex Screeding Knaphill

When the make-up of your floor's surface means that a certain degree of flexibility is required, it will be advantageous to use a latex screeding, rather than one with a more rigid finish. Latex screeds generally comprise two parts - a cementitious powder and a latex liquid mixture. Latex screeds are quicker drying and more flexible than other types of screed, as the water which is normally used is substituted for the liquid latex.

Used in the levelling of subfloors, this latex product creates a surface for the laying of the final floor finish. Producing a resilient, smooth surface that is ideal for the application of flooring adhesives, this screed is is suitable for use on sub-floors of sand/cement, quarry tiles, concrete, asphalt and wood. This latex floor screed will produce a crack-free, flexible finish, even if there is movement in your subfloor.

With a "floating" screed, for example when a screed is being laid on the top of a layer of thermal or acoustic insulation, latex screeds will not be suitable. Floating screeds with a thickness of 50mm-75mm are normally used on top of underfloor heating.

Coloured Floor Screeds

In commercial or industrial settings, multi-coloured screeds are frequently utilised as a flooring material. The combination of coloured resins, aggregates, and sealers is what makes up these screeds, producing a unique and decorative finish. Their durability and slip-resistant properties make them a popular choice for areas with heavy footfall or machinery.

The branding of a business or the desired aesthetic in a space can be achieved by customising multi-coloured screeds. Facilities that demand a high standard of hygiene often select them due to their ease of maintenance and cleaning. In addition, coloured screeds offer a seamless finish that eliminates any grout lines or joints, making it a great choice for cleanroom environments. Overall, coloured floor screeds are a versatile and practical flooring solution that can add both style and function to any commercial or industrial space.
