Floor Screeding Harlow Essex (CM20): When you are upgrading your Harlow property with uneven or damaged floors, or maybe converting a cellar or basement to useable living space, a professional floor screeding company will be able to help with your home improvements. Before it is possible to lay a suitable floor covering, whether it is wood, tile or carpet, the floor base should be as flat as possible; which is why screeding a floor is often essential. If you want your floors to last then a floor screed is the most important factor in any renovation or building task.
FLOOR SCREEDING EXPERTS HARLOW
Whatever size or shape of room or area you're renovating, a local floor screeding company in Harlow will supply the expertise and correct working methods to generate the perfect base for your flooring. After evaluating your project they will advise you about the perfect choice of screed and which method of laying it is most appropriate for your circumstances.
It might be a requirement, based on the intended use of the room, for a survey by a structural engineer to conform with building regulations on flex strength, load bearing and point loadings of the screed floor.
Qualified and skilled workers are necessary for a successful outcome and will extend the lifespan of your floor by using the right sort of screed for your room's allocated purpose. There are many kinds of screeding and picking the right mix and installation method is essential if you are to achieve a quality floor that's fit for purpose and long-lasting.
Ensure that you get two or three quotes for your Harlow based floor screeding project and also ask to what standard you're getting a quote. The Surface Regularity (SR) finish is the number to keep your eye on when getting a quotation from your Harlow screeding contractor. SR2 and SR3 could be cheaper options, however the floor screeding finish may have errors and deviations, whilst SR1 guarantees a pretty much perfect finish. An SR2 or SR3 standard might mean there are flat spots or ridges that may cause problems when laying your final flooring materials.
Every Harlow screeding company has to observe British Standards (BS8204) and ought to have accreditation from screeding material and equipment manufacturers, for instance Cemfloor, Gypsol, Flowcrete. This accreditation scheme illustrates a contractor's training and performance in the usage of a manufacturer's merchandise.
Harlow commercial screeders could be involved in screeding floors in factories, hospitals, shops, warehouses, boutiques and schools.
TYPES OF SCREED
Standard Screeds - This is perfect for normal residential usage and is a mix of sand and cement. The ratios involved in standard screeds are five parts sand to one part cement. The standard screed dries at a rate of 1mm thickness each day.
Fibre Reinforced Screed - The professional's choice for residential use on top of under floor heating. The improved flex and strength offered by the special fibres within the screed help protect the flooring from thermal shrinkage and cracking. The screed will dry out at a rate of roughly 1mm/day.
Industrial and Heavy Duty Screed - Designed for maximum durability and strength on floors where traffic is high or specific loading of the floor is necessary.
Polymer Screeds - A high strength flooring solution where a reduced thickness is essential. Due to their different chemical compositions, these polymer screeds have varying curing times which can be verified by studying manufacturer's product guidelines.
Fast Drying and Advanced Drying Screeds - If there is a need to press ahead urgently with the work due to time restraints, this screed dries much faster than standard screeds. These are usually a fibre reinforced type of screed which can dry out at a rate of between three and seven millimetres per day and are used in time-sensitive flooring projects.
Self-Levelling or Liquid Screeds - A cement and latex material which can produce the highest standard SR1 finish. This is mostly needed to provide a smooth, level floor over the top of a damaged or poor quality substrate and enables all types of flooring materials to be used. They can be as little as one millimetre in depth, and because of the latex polymers, will still provide a high strength finish.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a good quality finish which is hard wearing and durable, time should be devoted to preparing the area before any screed is laid. Any paint, debris, grease and oil on the original floor level can affect the adhesion of the screed, and must be eliminated.
Any cleansing products that are used during this process shouldn't leave any residues, and the floor base must be allowed to dry out naturally. It's necessary to repair any cracks in the base to stop them being mirrored and "travelling" up into the freshly screeded floor. A site survey will allow the screeding company to take note of these preparation areas and complete them before beginning to lay the screeding.
To shield the flooring materials and screed layer from moisture rising up through the ground, a DPM (damp proof membrane) will have to be laid. There might be two or three layers of different thicknesses of polythene to act as a barrier between the screed and the insulation layer.
If the area where you live is at risk from radon gas then a further barrier is required to stop the gas from entering from the ground. If radon gas occurs in severe doses then a full ventilation and extraction system may be installed beneath the layer of screed which will extract any gases that are seeping in from ground level.
As soon as the floor base has been prepared and all DPMs installed, a sealer or primer is then applied. These sealers and primers will guarantee the screed bonds properly to the floor base and help to create a top quality finished floor. Custom-made equipment such as airless sprays can be used to apply a primer or sealant, which should be done by experienced screeding contractors in Harlow following the manufacturer's guidelines.
Underfloor heating can now be installed and tested before the screed is applied. The heating pipes and wires are securely attached to insulation panels to stop any movement and ensure they're positioned correctly. When expertly installed an underfloor heating system is an efficient way to warm a room and top quality screed will retain its heat, generating an even heat right across the floor.
If you're not putting in underfloor heating the screed can now be prepared on site and laid. The specific requirements of the room will dictate the form of screeding used. After the pouring of the screed there's a minimum twenty four hours (for quick drying screeds) before you are able to walk on the surface, and a 72 hrs minimum curing period for any floor covering installation. This period is longer for heavy duty and standard screeds and the manufacture's product guidelines should be followed to create the best finish and durability of the floor.
The SR level of your screeding can be ascertained once it's solidified sufficiently to be walked upon. The test involves using a 2 mtr long straight-edge laid on the surface and any deviations from true are measured.
- SR1 - Deviations of 3mm or less as measured over the whole area shows your screed floor to be of the finest quality and is specified as SR1.
- SR2 - If the screeded floor deviates from the straight edge by 5mm or less it is classified as SR2 quality and is the normal standard for commercial and industrial floors.
- SR3 - SR3 is basic utility standard where a perfect finish isn't necessary. This level allows for a maximium deviation of 10 millimetres.
It might also be necessary for a structural engineer to conduct a soundness test. Using specialist equipment the engineer will ascertain the screed strength and its suitability for use in a load bearing environment. An assessment called the drop hammer test is performed at several areas on the screed and the outcomes noted. The precise testing and measurement tools mean that this can only be carried out by a fully qualified structural engineer respecting the BS8204 guidelines.

Latex Screeding Harlow
When a level of flexibility is necessary in a floor's surface you might find that the employment of a latex screed will be advantageous. Latex screeds come in 2 parts - a bottle and a bag - with a bottle that contains liquid latex, and a bag that contains a cement based powder. The liquid latex solution replaces the water that would typically be used for mixing screed, and is quicker drying and much more flexible than standard screeds.
This latex screed is used to level-out a sub-floor prior to the final decorative surface being installed. Suitable for substrate of concrete, quarry tiles, asphalt, wood and sand/cement, this screeding gives a perfect surface for the application of adhesives which is smooth and resilient. If there's any movement in the sub-floor this latex floor screed will give you a crack-free, flexible finish on which you can lay your final floor coverings.
When using a "floating" screed, for instance when screed is being laid on top of underfloor heating, depths of 50 to 65 millimetres may be desirable, and latex screeds are not a suitable choice in this instance.
