Floor Screeding Hendon Greater London (NW4): You should get in touch with a professional in Hendon if you are looking to install underfloor heating, have a damaged or uneven floor or are renovating a property or basement. Floor screeding provides a smooth, level finish to a basic sub-base floor, and enables you to lay your final layer of flooring material, (carpets, tiles, boards etc) on top of it. The screed is a vital procedure to guarantee a durable and quality finish to the entire floor structure.
FLOOR SCREEDING COMPANIES HENDON
Having all of the know-how and experience to help you achieve a perfectly finished floor in whichever shape or size of room you're working on, a professional floor screeding specialist in Hendon is the best choice for your screeding project. After a painstaking evaluation of your project, they will be in a position to advise you on which method of laying is most suitable for your situation, and what is the best choice of screed to use.
They'll in addition assess if a structural engineer is necessary to ensure any point loadings, load bearing and flex strength are satisfied in accordance with the building regulations.
The training and skills that a certified screeding contractor brings to your project should guarantee a high quality end result and help to extend the lifetime of your floors. Picking the appropriate screeding materials and the method of installation is crucial if you want to finish up with a quality and durable finish for your floor surface.
Before picking out a screeding company from any based in the Hendon area, ask to what standard of finish they are basing their estimate, and also make certain you get multiple quotations. The quote should be based on what is known as the Surface Regularity, or SR number. Each of the 3 SR levels provide different levels of finish, with SR1 being the best, with the lowest amount of deviation over the surface area. This means you may have to correct any areas that may cause issues when laying your finished flooring material.
British Standards BS8204 lays down the regulations and guidelines that all Hendon screeding installers must follow, and if using specialist screeding solutions, (Flowcrete, Cemfloor, Gypsol etc), they must be accredited by the manufacturers as being skilled and trained in their use. A contractor holding such accreditation indicates that they've been assessed and trained in using these products and can provide a high standard of service in all areas of their installation.
Hendon commercial screeders might be involved in the screeding of floors in shopping centres, schools, hospitals, factories, warehouses and pubs.
TYPES OF SCREED
Standard Screeds - A mixture of sand and cement which is okay for basic domestic use. The ratios involved are five parts sand to one part cement. After being laid a standard flooring screed mixture sets at a rate of 1mm/day.
Advanced Drying and Fast Drying Screeds - If there's a need to use the area in question ASAP a fast drying screed may be used. They are normally a fibre reinforced kind of screed that dries out at a rate of between 3-7mm per day and are used in time-sensitive flooring projects.
Industrial and Heavy Duty Screed - Where traffic levels are expected to be high or heavy loading of the floor is necessary, heavy duty screeds allow for maximum durability and strength.
Fibre Reinforced Screed - Used mostly with under floor heating systems and is the suggested choice in these projects. This is because of the increased durability and protection against thermal shrinkage and cracking offered by the special fibres within the screed. It's got a setting rate of 1mm per day.
Self-Levelling or Liquid Screeds - A cement and latex mixture which can achieve the highest standard of finish to SR1 levels. Mainly used to finalise a poor substrate level or damaged floor in order to lay a brand new flooring surface, like tiles over the top of it. The liquid screed can be poured to a thickness of only 1mm, but will still provide a strong surface for a wide range of flooring materials.
Polymer Screeds - When a reduced thickness of floor is necessary due to building requirements, a polymer screed offers an extremely high strength solution to this problem. Because of their different chemical compositions, these screeds have varying drying times which can be verified by checking manufacturer's product guidelines.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to fully prepare the area prior to any other work so as to guarantee a hard wearing and quality screed flooring. It's crucial that any contaminants such as grease, paint, oil or loose debris is eliminated from the base before pouring any screed, as these can affect the bonding process that a good quality screed demands.
If cleansing products were used it is essential to remove any remnants of soap etc, and leave the floor surface to dry naturally. If screeding over a cement or stone floor any cracks should be mended to stop them from "travelling" up through a screed layer and causing deviations on the final floor surface. An on-site survey will allow the screeding specialist to highlight this preparation work and finish it before beginning to apply the screed layer.
A DPM (damp proof membrane) will be put down once the preparation work has been completed to prevent ground dampness affecting the screeding and floor materials. The damp proof membrane is made of thick polythene sheeting and different layers may be used to serve as a moisture barrier for the screeding.
If the area is at risk from radon gas then a further barrier is essential to prevent the gas from entering via the ground. A simple air-tight membrane might be suitable in areas with low emissions of radon, but in more severe situations there might have to be a more complicated extraction system to block any harmful radon gases.
As soon as the base has been prepared and any DPMs installed, a primer or sealant is then applied. These primers and sealers will make certain that the screed bonds effectively to the base and help to create a high quality finished floor. These products need trained technicians to apply them in the appropriate proportions by using tailor-made equipment, such as airless sprays.
Underfloor heating can now be installed and tested before the screed is applied. The under floor heating system is laid out in the correct pattern and attached firmly to insulation panels to avoid any movement in the course of the screed pouring. Warmth will be spread evenly across the floor in an expertly installed under floor heating system, and along with it being an effective method of heating, it's a good choice for most Hendon renovation projects.
If you're not fitting underfloor heating the screed can now be prepared in situ and laid. Your proposed use of the room will assist your screeding specialist on which sort of floor screed is ideal for your requirements. For advanced and quick drying screeds there'll be at least a 24 hour delay before it is able to be walked on, and a further seventy two hours minimum before you are able to lay any flooring materials. Such timescales will be longer for standard and heavy duty screeds and the manufacture's product guidelines should be followed to accomplish the best finish and longevity of the floor.
Once the screeding has solidified it can be checked for quality to verify the SR level. Through the use of a two metre straight-edge the surface is examined for any dips, ridges and deviations in the surface of the screed.
- SR1 - SR1 is the highest quality and permits only 3 millimetres of disparity from the straight-edge.
- SR2 - SR2 is for standard floors in industrial and commercial projects and can deviate from the straight-edge by as much as five millimetres.
- SR3 - For a utility area or room where the quality of finish is fairly immaterial the SR3 is the classification and has a deviation measurement of 10mm or less.
If your screed floor has been installed with particular loading in mind then a structural engineer is going to be needed to conduct tests. The assessment will make sure that your new screeded surface is viable for the load bearing requirements laid out in the site survey. The screed could be subjected to a "drop hammer test" to measure strength and flexibility at different points. The precise measurement and testing tools mean this can only be conducted by a fully qualified structural engineer heeding the guidelines of the British Standards BS8204.

Latex Floor Screed Hendon
When the characteristics of your floor's surface means that a bit of flexibility is required, it may be an advantage to apply a latex self-levelling screed, rather than one with a more rigid finish. Latex screeds usually comprise two parts - a cementitious powder and a liquid latex additive. Latex screeds are quicker drying and more flexible than other types of screed, because the water that is normally used is exchanged for the latex liquid.
This latex compound is used for levelling-out sub-floors prior to the laying of the final decorative surface. This screed is appropriate for sub-floors made from concrete, quarry tiles, asphalt, wood or sand/cement, is perfect for the application of adhesives and gives a durable and smooth surface. If your subfloor has any movement in it, this type of floor screed will give you a crack-free, flexible finish, upon which your chosen floor coverings can sit.
When an unbonded screed is being laid over a layer of either acoustic or thermal insulation (i.e. a floating screed), latex flooring screeds are not a suitable choice, because in such cases (normally when screeding over underfloor heating), you'll likely require a thickness of 50 to 75 millimetres.
