After analyzing your project they'll advise you on the perfect choice of screed and which method of laying it is most suitable for your situation.
It might be a requirement, depending on the proposed use of the space, for a structural engineering survey to conform to building regulations on point loadings, load bearing and flex strength of the screed floor.
Qualified and skilled tradespeople are essential to a successful result and will extend the life of your floor by making use of the right type offor your room's allocated purpose. A correct mix of screed and the methods used for laying it are also crucial to ensure the final quality of your floor.
Ensure you get at least 2 or 3 quotes for your Sutton based floor screeding project and also ask to what standard you're getting a quote. The estimate could be based on what's known as the SR, or Surface Regularity number. Each of the three SR levels provide different levels of finish, with SR1 offering the best, with the smallest amount of deviation over the area of the floor. This means that you may need to fix any areas that may cause problems when putting down your finished flooring material.
All Sutton screeding installers must observe British Standards (BS8204) and should have accreditation from screeding material and equipment manufacturers, for instance Cemfloor, Gypsol, Flowcrete. This accreditation scheme demonstrates a company's training and ability in the application of a manufacturer's screeding merchandise.
Commercialin Sutton will generally undertake screeding projects in schools, warehouses, hospitals, shops, boutiques and factories.
TYPES OF SCREED
Standard Screeds - Used in residential projects where the combination of sand and cement is perfectly acceptable for basic footfall use. This mixture comprises a 5:1 ratio of sand to cement. After laying a standard flooring screed dries out at a rate of just 1mm/day.
Industrial and Heavy Duty Screed - Made for maximum durability and strength in areas where traffic is expected to be high or heavy loading on the floor is required.
Advanced Drying and Fast Drying Screeds - If there is a need to progress urgently with the work owing to time limitations, these screeds dry much quicker than standard screeds. The vast majority of the fast drying screeds are of thekind and are appropriate for a whole host of projects where the quicker curing rate of 3-7mm/day is a welcome advantage.
Polymer Screeds - When a reduced thickness of floor is needed on account of building requirements, aoffers an extremely high strength resolution to this situation. Manufacturer's guidelines for curing times differ across the product ranges.
Self-Levelling or Liquid Screeds - When a high standard of finish is needed this formula of cement and latex is used to create SR1 level floor screeding. This self-levelling compound provides a clean and smooth surface over a rough substrate or damaged floor to enable all flooring materials to be laid. Even with a depth of just one millimetre, thewithin the mixture provide a high strength surface for a wide variety of uses.
Fibre Reinforced Screed - The favoured choice by professional installers for use with underfloor heating systems. This is due to the improved strength and protection against thermal cracking and shrinkage offered by the fibres within the screed mix. It dries out at the same rate as a standard screed of one millimetre per day.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is vital for a high qualitythat will be durable and hard wearing. Any paint, oil, grease and debris on the original floor level can affect the adhesion of the screed, and must be eliminated.
If cleansing products were used it's essential to remove any traces of soap etc, and leave the floor surface to dry naturally. At this stage cracks need to be mended since these can travel up through your newly laid screed and be reflected in the completed floor surface. During a site survey the screeding installer will be able to see what preparations are needed before any actual screeding work commences.
A DPM (damp proof membrane) will be applied once the preparation work has been completed to stop ground moisture getting into the flooring materials and screeding. The DPM is made out of thick polythene sheeting and different layers may be used to act as a moisture barrier for the screed.
Another airtight barrier might be needed if your home or business premises is in a location that is known to be prone to radon. This could be just a simple airtight membrane, or in more serious instances a ventilation system will need to be installed beneath the floor screed to take away any inflow of air and gas from the ground.
Once these stages have been completed the screeding company will apply a sealer or primer to the prepared floor base. These primers and sealers will ensure the screed bonds properly to the floor base and help to achieve a good quality finished floor. Equipment such as airless sprays will usually be used to apply a primer or sealant, which should be done by professional screeding contractors in Sutton observing the manufacturer's guidelines.
If you are installing underfloor heating, this is the time that it will need to be laid out and installed. The underfloor heating system will be carefully positioned and firmly attached to insulation panels to stop potential movement in the course of the screed pouring process. Warmth will be evenly spread across the floor in a professionally installed under floor heating system, and with it being an efficient method of heating, it is a great choice for most Sutton home restoration projects.
If you are not installing underfloor heating the screed will now be prepared on site and laid. The specific requirements of the room will dictate the type of screeding used. For quick drying screeds there will be at least twenty four hours delay before it can be walked over, and a further 72 hours minimum before you are able to install any flooring materials. Such periods will be increased for standard and heavy duty screeds and the manufacture's guidelines should be followed to the letter to accomplish the optimal finish and longevity of the floor.
As soon as the screed has set it can be checked for quality to verify the SR level. The test involves the use of a 2 metre long straight-edge laid on the surface and any variations from true are calculated.
- SR1 - Deviations of 3mm or less as measured over the entire area shows your screed floor to be of the best quality and categorised as SR1.
- SR2 - SR2 is for standard floors in industrial and commercial projects and can deviate from the straight-edge by as much as 5 millimetres.
- SR3 - For other floors where the finish is relatively inconsequential the SR3 is the standard and has a maximum deviation measurement of ten millimetres or less.
If you need to check the floor for load bearing, a structural engineer is necessary to carry out the tests. The assessment will make certain that your new screeded surface is suitable for the load bearing requirements specified in the original site survey. The screeding could be given what's known as a "drop hammer test" to assess strength and flexibility at various points. Any screed flooring that's got load bearing requirements must be okayed by a fully qualified structural engineer obeying the BS8204 regulations.
