Floor Screeding Chalk Farm

Floor Screeding Chalk Farm Greater London (NW1): If you are restoring a property or cellar, have an uneven or damaged floor or are aiming to install underfloor heating in your Chalk Farm home, then it's time to consider hiring a professional floor screeder. Before it is possible to lay a final floor covering, be it wood, carpet or tile, the surface of the floor should be as flat as possible; which is why floor screeding is sometimes essential. Screeding a floor enables you to provide a durable, quality finish for any room in your home or office.

FLOOR SCREEDING CONTRACTORS CHALK FARM

A reputable screeding firm in Chalk Farm will have all the know-how and experience to help you achieve a perfectly finished floor in whatever shape or size of room you are renovating. After a painstaking evaluation of your screeding project, they will be able to advise you on which method of laying is most suitable for your floor, and what is the best kind of screed.

It may be necessary, according to the intended use of the room, for a structural engineering survey to abide by building regulations on flex strength, load requirements and point loadings of the screed floor.

Bringing in a qualified and highly trained specialist will guarantee you use the appropriate kind of screed for the room's intended purpose and get the maximum lifespan out of the resulting floor. There are many types of floor screeding and selecting the correct mix and installation technique is vital if you are to achieve a quality floor that is both hard-wearing and fit for purpose.

There are numerous screeding contractors in the Chalk Farm area so if possible get multiple quotations for your screeding project before choosing a contractor and know to what standard of finish it's for. The SR (Surface Regularity) finish is the figure to look for when getting a quote from your Chalk Farm screeding contractor. Each of the three SR levels offer different standards of finish, with SR1 being the highest quality, with the lowest amount of deviation over the surface area. This means you might have to correct any patches that could cause problems when putting down your final flooring solution.

The regulations and guidelines specified in the British Standards BS8204 have to be followed by all Chalk Farm floor screeding contractors and they must also hold accreditation with the manufacturers of any specialist screeding materials (Gypsol, Cemfloor, Flowcrete etc.) to substantiate their competence and safe working practices. A company holding such accreditations demonstrates they've been trained and assessed in using these products and can deliver a high quality standard in all areas of their installation.

TYPES OF SCREED

Standard Screeds - This is okay for standard domestic usage and is a mix of cement and sand. The ratios involved are five parts sand to one part cement. After laying a standard screed sets at a rate of just 1mm/day.

Liquid or Self-Levelling Screeds - Used to produce a high quality finish, especially where SR1 levels are required, by a latex and cement formula. It is mostly needed to provide a clean, smooth floor over the top of a damaged or poor quality substrate and enables all types of flooring materials to be used. These can be as little as 1mm thick, and because of the latex polymers, will still provide high strength.

Fibre Reinforced Screed - Used with underfloor heating and is the advised choice in these projects. The improved flexibility and strength offered by the fibres in the screed help protect the flooring from thermal cracking and shrinkage. At roughly 1mm per day, it has the same curing rate to standard screed.

Industrial and Heavy Duty Screed - A screed designed for high load and heavy traffic areas where the maximum possible durability and strength is very important.

Fast Drying and Advanced Drying Screeds - If you have to use the area as quickly as possible a fast drying screed can be utilised. Drying out at a rate of 3-7mm, depending on the mixture, they're generally a fibre reinforced kind of screed and are ideal for flooring projects which have tight deadlines.

Polymer Screeds - A high strength flooring solution where a reduced thickness is required. Polymer screeds are available from many screed manufacturers and due to their different chemical compositions have distinct drying times for each product.

SCREEDING PREPARATION AND INSTALLATION

To make certain that the screeding is of a high quality finish that's hard wearing and durable, time should be spent on carefully preparing the area prior to any screeding material being laid. It is crucial that all contaminants such as grease, paint, loose debris or oil is eradicated from the base before pouring any screed, because these can affect the bonding process that a good quality floor screed requires.

If any cleaning products were used in this process it's vital to ensure that no residues of soaps or other cleaning products are left on the surface and it's permitted to dry out naturally. It is necessary to mend any cracks in the base to avoid them being mirrored and "travelling" upwards into the freshly screeded floor. During a site survey your Chalk Farm screeding installer will notice what preparation work is needed before any actual screeding work commences.

A damp proof membrane (DPM) will be applied after the preparation work has been concluded to stop ground moisture getting into the screed and floor materials. Different gauges of specialised polythene may be used as a damp proof membrane and also act as a barrier for the screed and any insulation panels.

If your property is located in an area where radon gas is present an additional barrier layer is required to stop radon gas from entering. An air-tight membrane might be sufficient in areas with relatively low levels of radon, but in more extreme situations there may need to be a more sophisticated extraction system to block any harmful radon gases.

As soon as these stages have been completed the screeders will apply a sealant or primer to the prepared floor base. These primers and sealers will make certain that the screed bonds properly to the floor base and help achieve a top quality finished floor. These materials require trained contractors to apply them in the right proportions by using custom-made equipment, such as airless sprays.

Before the screeding is poured, any under floor heating (if required) will now be installed. Insulation panels can be put in position and the heating pipes and cabling will be firmly attached to prevent any movement while the screed is being applied. Under floor heating is one of the most effective ways to heat a room and a skillfully installed system should produce even warmth across the floor area.

Naturally, if you're not putting in under floor heating, you simply ignore this step and get on with applying the floor screed. Your use of the room will help your screeding contractor on which kind of floor screed is best for your requirements. After the pouring of the screed there is a minimum twenty four hours (for advanced and quick drying screeds) before you are able to walk on the surface, and a 72 hours minimum setting period for any floor material installations. If you're using heavy duty or standard screeds the drying time is longer and the manufacturer's guidelines must be adhered to so as to get the best finish for your floor.

You can test the SR standard of the finished screed as soon as it is set enough to walk on. The test involves the use of a 2 metre straight edge laid on the surface and any variations from true are calculated.

• SR1 - Disparities of three millimetres or less being measured over the whole floor area shows your screeding to be of the finest quality and is classified as SR1.

• SR2 - If the screeded surface has a deviation from the straight-edge of 5 millimetres or less it is classified as SR2 quality and is the normal standard for commercial and industrial projects.

• SR3 - If the deviation around the room is 10mm or less the screeding quality is specified as SR3 and is suitable for utility and garage areas.

There may also be a requirement for a qualified structural engineer to carry out a soundness test. This assessment will determine the overall strength of the screeded surface and its viability for the intended use. An assessment called the drop hammer test will be performed at several areas on the screed layer and the results recorded. Any screed floor that's got point load requirements must be sanctioned by a certified structural engineer heeding the British Standards BS8204 guidelines.

Screed Reinforcement

The technique for reinforcing concrete screeds using screed reinforcement is implemented to improve their strength and durability. Level surfaces are produced by applying flat, thin layers of concrete to a base layer, known as screeds. Their typical application in building projects is as flooring, although they can also be used as a finishing layer for ceilings and walls.

To prevent cracking and increase the strength of the screed, reinforcement materials such as wire, fibres or steel mesh are embedded within the screed mixture during the installation process. The reinforcement of the surface evens out the distribution of load and weight while also increasing its resistance to impact, abrasion and thermal changes.

In addition to improving the screed's durability and strength, screed reinforcement also helps to reduce the risk of shrinkage and cracking caused by changes in humidity or temperature. Even distribution throughout the screed and avoiding displacement over time are dependent on the correct installation of the reinforcement, which is essential. For a long-lasting and reliable surface suitable for various applications, the use of screed reinforcement is essential to maintain the quality and structural integrity of screeds.

Latex Screeding

When a bit of flexibility is needed in the surface of a floor you might find that the use of a latex self-levelling screeding will be best. Latex screeds come in 2 parts - a bottle and a bag - with a bottle that contains liquid latex, and a bag that contains a cemetitious powder. The latex liquid additive actually replaces the water that would typically be used in a screed mix, and is quicker drying and far more flexible than standard screeds.

This latex product is used for levelling-out sub-floors prior to the laying of your chosen decorative covering. Suitable for substrate of sand/cement, concrete, wood, stone tiles and asphalt, this screed gives a perfect surface for the application of adhesives which is resilient and smooth. Even when there is a bit of movement on your subfloor, this latex screeding will provide a crack-free, flexible finish.

When using a "floating" screed, for example when screeding is being laid over underfloor heating, depths of 50mm-75mm may be needed, and latex floor screeds aren't suitable in this case.

Granolithic Screeding

Granolithic screeding is a process of creating a smooth and even surface for floor coverings like carpets or tiles. It involves mixing aggregate, cement and sand to form a mixture, which is then applied to a concrete sub-base. The mixture is levelled with a straight edge to give it a smooth surface.

This technique is typically used in commercial and industrial buildings, high-traffic residential areas, and spaces that require abrasion and chemical resistance. The resulting surface is durable, easy to clean, and provides a perfect base for other flooring materials.

The granolithic screeding process involves preparation of the concrete sub-base, mixing the screed mixture, laying the mixture, and giving it time to cure. Correct application and curing techniques are crucial for the strength and longevity of the screed. The screed must be completely cured before any further flooring products are installed.

Screed Floor Removal Chalk Farm

The removal of screed from a surface is a practice that involves extraction and elimination. Often, when upgrading or refurbishing a floor, it is a necessary undertaking. The removal process relies on specialised techniques and equipment to break down and remove the screed layer with effectiveness. This grants the opportunity to prepare the surface for new flooring material or other modifications. By specialising in screed floor removal, contractors ensure the efficient and safe removal of the old screed, enabling the floor to start afresh, whether for design variations, upgrades or repairs.
