Floor Screeding Spalding Lincolnshire (PE11): If you are hoping to install under floor heating, are renovating a property or basement or have a damaged or uneven floor, then you'll be needing to find a specialist service to help you. Screeding is important to provide a flat and even floor surface upon which you can install you final floor covering, be it carpet, tile or wood. A floor screed is a fundamental element of many building and restoration projects in Spalding.
FLOOR SCREEDING EXPERTS SPALDING
Having all of the know-how and experience to help you achieve a perfectly finished floor in whatever shape or size of room you are working on, an experiencedin Spalding is the ideal choice for your screeding project. They will be able to assess your project and ascertain the correct kind of screed you need and the best technique for applying it.
It may be a requirement, according to the proposed use of the area in question, for a structural engineering survey to conform to building regulations on point loadings, load requirements and flex strength of the screed floor.
Working with a qualified and highly trained flooring specialist will guarantee that you use the correct kind offor the room's anticipated purpose and get the maximum lifespan out of your floor. Choosing the appropriate screeding materials and the method of installation is crucial if you want to end up with a durable and quality finish for your floor.
There are numerouscontractors in the Spalding area so see if you can get multiple price quotes for your screeding project before picking a company and know to what standard of finish is it for. The quote could be based on what is known as the Surface Regularity, or SR figure. SR1 is the best quality, and while SR2 and SR3 might be more cost-effective initially, they do not guarantee a totally flat or even surface. An SR2 or SR3 level may mean there are ridges or flat spots that could cause issues when installing your final flooring surface (carpet, wood, tile etc).
The regulations and guidelines set out in in the British Standards BS8204 have to be observed by any Spalding floor screeding company and they must also be certified by the manufacturers of specialist screeding materials (Cemfloor, Flowcrete, Gypsol etc.) to demonstrate their competence and safe working practices. This accreditation program illustrates a contractor's ability and training in the usage of a manufacturer's product.
Commercialin Spalding will generally undertake screeding projects in schools, shopping centres, salons, warehouses, factories and hospitals.
TYPES OF SCREED
Standard Screeds - This is good for basic residential usage and is a mix of cement and sand. This mixture uses a 5:1 ratio of sand to cement. Once laid this 5:1 ratio will dry at a rate of 1mm each day.
Fibre Reinforced Screed - The favoured choice by professional contractors for use with under floor heating systems. This is because of the increased durability and protection against thermal cracking and shrinkage offered by the special fibres within the screed mix. It dries out at an identical rate to a standard screed of 1mm per day.
Industrial and Heavy Duty Screed - Designed for maximum strength and durability in places where traffic is high or specific loading of the floor base is required.
Polymer Screeds - When a lower thickness of floor is needed on account of construction requirements, a polymer screed provides an extremely high strength resolution to this situation. Polymer screeds are available from many screed manufacturers and owing to their different chemical compositions have specific curing times for each product.
Fast Drying and Advanced Drying Screeds - If you need to press ahead urgently with the flooring because of time restraints, this screed dries much faster than standard screeds. They are typically akind of screed that dries out at a rate of between three and seven millimetres per day and are used in time critical flooring projects.
Liquid or Self-Levelling Screeds - A cement and latex solution which can produce the highest standard of finish to SR1 levels. It is primarily needed to provide a smooth, level floor over a damaged or poor quality substrate and results in a finish onto which all kinds of flooring materials can be laid. Even with a thickness of just 1mm, the latex polymers within the screed provide a high strength surface for a wide range of uses.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is essential for a quality finished screed surface that will be hard wearing and durable. The existing floor surface should be cleaned to eliminate any grease, paint, debris and oil which can adversely affect the bond of the screeding.
If any cleaning products were used during this stage it's vital to ensure that no residues of soaps, detergents or other cleaning products are left on the floor surface and it is allowed to dry out naturally. If screeding over a cement or stone floor then all cracks should be repaired to prevent them from "travelling" through a screed layer and resulting in deviations on the final floor surface. During an on-site survey your Spalding screeding installer will ascertain what preparations are needed before starting to work on the screeding.
To shield the flooring materials and screed layer from dampness rising up through the ground, a DPM (damp proof membrane) will have to be laid. Different gauges of polythene sheets may be used as a damp proof membrane and also act as a barrier for the screed and any insulation material.
If the area is susceptible to radon then a further barrier is needed to prevent this harmful gas from entering from the ground. If radon gas occurs in large amounts then a full ventilation system might be needed underneath the screed which will extract any gases that are seeping in from the ground.
As soon as the floor base has been prepared and any DPMs installed, a primer or sealant is then put on. Primers and sealers help with the bonding process and are specialist applications according to the kind of screed that's being applied. Owing to their specialist nature, only experienced screeding contractors in Spalding are capable of using them safely and correctly and through the use of equipment that's made for the task.
Under floor heating can now be laid out, installed and tested before screeding is poured. The under floor heating system will be carefully positioned and attached firmly to insulation panels to prevent potential movement during screed pouring process. Warmth will be evenly spread across a floor area in an expertly fitted under floor heating system, and along with it being an efficient choice of heating, it is a great choice for the majority of Spalding renovation projects.
The screeding can now be prepared in situ and spread onto the floor surface. The particular requirements of the room will dictate the sort of screeding that is used. After the pouring of the screed there will be a minimum twenty four hours (for quick drying screeds) before you're able to walk upon the surface, and a 72 hours minimum curing time for the laying of any floor coverings. This timescale is increased for standard and heavy duty screeds and the manufacture's guidelines must be followed to produce the optimal finish and longevity of the floor.
You can assess the SR level of the finished screeding as soon as it's hardened enough to walk on. Using a 2m straight-edge the surface is checked for any dips, ridges and deviations in the screed surface.
- SR1 - Deviations of 3mm or less as measured over the whole area shows your screed floor to be of the highest quality and classified as SR1.
- SR2 - If the screeded surface deviates from the straight edge by 5mm or less it is considered SR2 level and is the standard for commercial and industrial floors.
- SR3 - SR3 is utility standard where a perfect quality finish isn't necessary. This specification allows for a maximium deviation of ten millimetres.
If you require load bearing checks, a qualified structural engineer is needed to perform the tests. Using specialist equipment the engineer will assess the screeding strength and its suitability for use in a load bearing setting. A drop hammer test is carried out on various areas of the screed and the outcomes documented. Any screeding that has load bearing requirements must be approved by a fully qualified structural engineer heeding the BS8204 guidelines.

Latex Screeds Spalding
When the characteristics of your floor's surface means that a bit of flexibility is needed, it may be advantageous to apply a latex floor screed, rather than one with a more rigid finish. Usually coming in two parts, latex floor screeds comprise a cementitious powder and a liquid latex mixture. Whereby water is normally used in a screed mix, this is replaced with the liquid latex, which makes it more flexible than standard screeds, and quicker drying.
This latex product is used for levelling-out sub-floors in advance of the laying of your chosen decorative surface. Suitable for sub-floors of concrete, wood, stone tiles, asphalt and sand/cement, this screeding gives the ideal surface for the application of adhesives that is resilient and smooth. This type of latex screeding will give you a crack-free, flexible finish, even if there's a bit of movement in your sub-floor.
When using a "floating" screed, i.e. when screeding is being laid over underfloor heating, depths of 50 to 75 millimetres may be needed, and latex screeds aren't a suitable choice in this instance.
Multi-Coloured Floor Screeds
Industrial or commercial settings often use multi-coloured screeds as a flooring material. By mixing coloured aggregates, resins, and sealers, these screeds are produced, resulting in a one-of-a-kind, decorative finish. Commonly, they are used in areas with heavy footfall or machinery due to their ability to withstand wear and tear and provide a non-slip surface that is long-lasting.
Multi-coloured screeds offer customisation options to match the brand of a business or give a space a particular aesthetic appearance. Their easy-to-clean and maintain properties make them a favourite option for facilities that require a high level of hygiene. The ability to select aggregates based on colour, size and shape in coloured screeds gives designers and architects the flexibility to create bespoke flooring designs that meet their specific project requirements. Overall, a practical and versatile flooring solution, coloured floor screeds can add both function and style to any industrial or commercial space.
