Floor Screeding Haslemere Surrey (GU27): A professional floor screeding company can help install under floor heating, help with renovations or level a damaged or uneven floor on your Haslemere property, when necessary. Floor screeding gives a smooth finish to a rough sub-base, and will allow you to lay your final layer of flooring material, (tiles, boards, carpets etc) over it. The screed is an important procedure to ensure a high quality and durable finish to the whole floor surface.
FLOOR SCREEDING EXPERTS HASLEMERE
Whatever size or shape of room you are renovating, a decent floor screeding specialist in Haslemere will be able to provide you with the experience and correct working methods to establish a perfect base for your floor. They'll be ready to advise you on the right sort of screed your project requires, and the best methods for applying and installing it.
It might be a requirement, contingent on the intended use of the area, for a structural engineering survey to abide by building regulations on load requirements, point loadings and flex strength of the screed floor.
Qualified and skilled workers are imperative for a successful outcome and will extend your floor's lifespan through the use of the correct kind of screed for the proposed purpose of your room. There are many different kinds of screeding and selecting the correct mix and laying technique is vital to create a high quality floor that's fit for purpose and hard-wearing.
There are a number of screeding specialists in and around Haslemere so see if you can get multiple quotations for your floor screeding project before picking out a company and know to what standard of finish is it for. For residential homes a quote will generally be provided for a Surface Regularity (SR) level of SR1 or SR2. Each of the three SR levels deliver different standards of finish, with SR1 offering the best, with the lowest amount of deviation over the area of the floor. This means you might have to correct any areas that might cause problems when laying your final flooring solution.
The regulations set out in in the British Standards BS8204 have to be followed by all Haslemere floor screeding contractors and they must also be certified by the manufacturers of any specialist screeding materials (Gypsol, Cemfloor, Flowcrete etc.) to verify their safe working practices and competence. This accreditation program showcases a firm's training and ability in the application of a manufacturer's product.
Haslemere commercial screeders may be involved in screeding floors in warehouses, hospitals, hotels, schools, factories and shopping centres.
TYPES OF SCREED
Standard Screeds - This is acceptable for standard residential use and is a combination of cement and sand. This mix comprises a five to one ratio of sand to cement. Once its been laid this 5:1 ratio will dry at a rate of one millimetre per day.
Self-Levelling or Liquid Screeds - A cement and latex mixture which can achieve the highest standard of finish to SR1 levels. It is primarily needed to provide a smooth, clean floor over the top of a damaged or poor quality substrate and results in a surface onto which all types of flooring materials can be laid. This liquid screed can be poured to a depth of just 1mm, but will still provide a high strength surface to take a selection of flooring materials.
Fast Drying and Advanced Drying Screeds - If there is a need to use the area at the earliest opportunity a fast drying screed might be a good choice. Most of the fast drying screeds are of the fibre reinforced kind and are perfect for a wide range of projects where the faster curing rate of 3-7mm is a big advantage.
Industrial and Heavy Duty Screed - Where traffic levels are high or heavy loading of the floor is necessary, heavy duty screeds offer maximum strength and durability.
Polymer Screeds - When a decreased thickness of floor is needed on account of construction requirements, a polymer screed offers a high strength solution to the situation. Due to their different chemical compositions, polymer screeds have varying setting times which you can verify by checking manufacturer's own product guidelines.
Fibre Reinforced Screed - The favoured choice by professional contractors for use with under floor heating systems. This is due to the improved strength and protection against thermal cracking and shrinkage offered by the fibres within the screed. It has a setting rate of 1mm per day.
SCREEDING PREPARATION AND INSTALLATION
To enable the screeding to be of a high quality finish that's durable and hard wearing, time must be devoted to fully preparing the area before any screed is laid. The original floor surfaces should be thoroughly cleaned to remove any grease, paint, debris and oil which might adversely affect the bond of the screed.
Any cleaning products that are used during this phase should leave no residues, and the floor base must be permitted to dry by itself naturally. It is vital to fix any crevices or cracks in the base to prevent them being reflected and "travelling" up into your freshly screeded floor. During a site survey your Haslemere screeding installer will establish what preparation work is necessary before any actual screeding work begins.
Before any screeding can be poured a damp proof membrane (DPM) will have to be installed to protect the final flooring and screed from dampness. The damp proof membrane is made out of thick polythene and various layers might be used to act as a moisture barrier for the screed.
Another air-tight barrier might be required if your home or business premises is in an area which is known to be susceptible to radon. If radon gas is present in severe doses then a complete extraction and ventilation system might be needed beneath the layer of screed which will remove any gases that could seep in from ground level.
Once the floor base has been properly prepared and all membranes installed, a primer or sealer is then applied. Sealers and primers help with the bonding process and are special applications according to the type of screed that is being applied. Custom-made equipment such as airless sprays are used to apply a primer or sealant, by professional screeding companies in Haslemere following the manufacturer's guidelines.
Before the screeding is poured, any underfloor heating will now be laid out. The heating pipes and cabling are firmly mounted on insulation panels to stop any movement and make sure they are laid in the correct position. When expertly installed an underfloor heating system is an effective way to warm up a room and top quality screed will retain its heat, generating an even level of warmth right across the floor.
The screed can now be prepared on site and spread onto the floor surface. Your intended use of the room will assist your screeding company on what type of screed is ideal for your needs. After the pouring of the screed there will be at least twenty four hours (for quick drying and advanced screeds) before you're able to walk upon the surface, and a 72 hour minimum setting time before the laying of any floor coverings. If you are using standard or heavy duty screeds the setting time is increased and you must observe the manufacturer's guidelines so as to get the best possible finish to your floor.
Once the screeding has set it can be checked for quality to confirm the SR level. Using a 2m straight-edge the surface is examined for any dips, deviations and ridges in the surface of the screed.
- SR1 - SR1 is the best quality and allows only 3mm of deviation from the straight-edge.
- SR2 - If the screed has a deviation from the straight-edge of 5mm or less it is SR2 level and is the normal standard for industrial and commercial projects.
- SR3 - For utility floors where the quality of finish is comparatively unimportant SR3 is the specification and should have a maximum deviation measurement of 10 millimetres or less.
If you need to check the screed floor for load bearing, a structural engineer is needed to conduct the tests. The testing will make sure that your new screeded surface is viable for the load bearing requirements laid out in the original site survey. This should include what's known as a drop hammer test which assesses various aspects of the strength and flexibility of the screed. Any screeding that has load bearing requirements must be approved by a fully qualified structural engineer obeying the British Standards BS8204 regulations.

Latex Screeds Haslemere
When a degree of flexibility is required in a floor's surface you may find that the application of a latex screeding will be an advantage. Latex floor screeds generally comprise 2 parts - a cement-based compound, and a liquid latex mixture. Latex screeds are quicker drying and more flexible than standard screeds, as the water that is normally used is substituted for the liquid latex.
This latex screed is used to level a sub-floor before the final decorative surface is laid. Giving a smooth, resilient surface that is perfect for the application of flooring adhesives, this screed is is suitable for use on substrate of quarry tiles, asphalt, concrete, sand/cement and wood. This latex floor screed will provide a crack-free, flexible finish, even if there's a bit of movement in your sub-floor.
With a "floating" screed, for instance when an unbonded screed is being laid over a membrane of acoustic or thermal insulation, latex flooring screeds will not be a suitable choice. Floating screeds with a thickness of 50 to 65 millimetres are generally used over underfloor heating.
