Floor Screeding Cobham Surrey (KT11): If you have a damaged or uneven floor, are renovating a property or cellar or are aiming to install under floor heating, then you'll need to find a professional contractor to help you. Before you are able to lay a final floor covering, whether it's carpet, tile or wood, the floor base should be as flat as possible; this is why screeding a floor is frequently essential. The screed is a vital process to guarantee a durable and quality finish to the entire floor surface.

The skills and training that a certified screeding technician brings to your project will guarantee a successful result and help to lengthen the lifespan of your floors. The correct mixture of screed and the techniques used for laying it are also vital to ensure the final quality of your floor.
Before deciding on a floor screeding specialist from any operating in the Cobham area, ask to what standard of finish they're basing their price quote, and also ensure that you get multiple quotations from different companies.

TYPES OF SCREED
Standard Screeds - Widely used in domestic projects where the mixture of cement and sand is acceptable for normal floor traffic use. The ratios involved in standard screeds are five parts sand to one part cement. Once laid this 5:1 ratio dries at a rate of one millimetre per day.
Polymer Screeds - These provide a high level of strength with a lower thickness. Polymer screeds are available from a number of screed manufacturers and because of their varying chemical compositions have specific drying times for each individual product.
Industrial and Heavy Duty Screed - Designed for maximum strength and durability in areas where traffic is high or heavy loading on the floor is needed.
Liquid or Self-Levelling Screeds - When the highest possible standard of finish is required this mix of of cement and latex is used to create SR1 quality screeding. The self-levelling compound provides a clean and level surface over a rough substrate or damaged floor to enable all forms of flooring materials to be laid. Even with a thickness of only 1mm, the latex polymers within the mixture provide a high strength screed for a variety of uses.
Fibre Reinforced Screed - The preferred choice by professional screeders for use in combination with underfloor heating systems. The greater strength and flexibility offered by the special fibres within this screed mix help protect the floor from shrinkage and cracking due to heat. At approximately 1mm per day, it has an identical curing rate to standard screed.
Advanced Drying and Fast Drying Screeds - If there's a need to move forward urgently with the flooring on account of time constraints, these screeds dry more speedily than standard flooring screeds. The vast majority of the fast or advanced drying screeds are of the fibre reinforced kind and are ideal for a wide array of projects where the quicker drying rate of three to seven millimetres is advantageous.
SCREEDING PREPARATION AND INSTALLATION
Screeding installers will need to prepare the area before any other work so as to ensure a high quality and hard wearing screed flooring. Any debris, grease, paint and oil on the existing floor surface can adversely affect the bonding of the screed, and should be removed.
If any products are used in this process it's vital to make certain that no residues of detergents, soaps or other cleaning products are left on the surface and it's permitted to dry out naturally. At this point any cracks need to be mended because these can travel up through your newly laid screed and be visible in the finished surface. An on-site survey will enable the screeding installer to take note of these preparation areas and finish them before commencing to pour the screeding layer.
A damp proof membrane (DPM) will be installed once the preparation work has been concluded to prevent ground dampness affecting the flooring materials and screed. Different thicknesses of special polythene might be used as a damp proof membrane and also serve as a barrier for the screed and any insulation panels.
If the area is at risk from radon gas then another barrier is needed to prevent the gas from entering from the ground. An airtight membrane could be suitable in places with low radon emissions, but in more severe cases there may have to be a more complex extraction system to remove any ground penetrating radon gases.
The final phase of surface preparation is the spraying or painting of a primer or sealant. These primers and sealers will make sure the screed bonds properly to the floor base and help create a top quality finished floor. These materials need skilled contractors to apply them in the correct ratios by using custom-made equipment, such as airless sprays.
This is the time that underfloor heating can be laid out in the correct manner and installed. The underfloor heating system is laid out in the correct pattern and firmly mounted on insulation panels to stop any movement during screed pouring process. Warmth is evenly spread across a floor area in a skillfully fitted underfloor heating system, and along with it being an effective method of heating, it is an excellent choice for most Cobham home renovation projects.
The screed can now be prepared in situ and applied to the base. Your screeding contractor will have given you advice on which type of screed is best for your needs, according to your intended use of the room. Remember that even quick drying and advanced screeds have a minimum of twenty four hours before you can walk over any screeded surfaces and at least 72 hours before any flooring materials can be applied. This timescale is longer for standard and heavy duty screeds and the manufacture's guidelines should be followed to produce the optimal finish and durability of the floor.
You can check the SR standard of the finished screeding once it is set enough for walking on. Using a 2 metre straight-edge the floor surface is examined for any dips, deviations and ridges in the surface of the screed.
- SR1 - SR1 is the highest specification and permits just three millimetres of disparity from the straight-edge.
- SR2 - The normal standard flooring in industrial and commercial builds is normally SR2 and has a maximum deviation of 5 millimetres across the whole floor.
- SR3 - For other floors where the finish is relatively inconsequential SR3 is the classification and has a deviation measurement of 10 millimetres or less.
If you require load bearing checks, a structural engineer is needed to perform the tests. Using specialised equipment the structural engineer will evaluate the screed strength and its suitability for use in a load bearing setting. This should include a drop hammer test which assesses various aspects of the flexibility and strength of the screed. Only trained structural engineers applying the BS8204 guidelines are allowed to perform such testing and sign off on the structural safety of the screeding.
