TYPES OF SCREED
Standard Screeds - A combination of sand and cement which is okay for everyday domestic usage. 5 parts sand to 1 part cement is the typical mixture for standard screeds. After being laid a standard screed mix dries out at a rate of 1mm/day.
Advanced Drying and Fast Drying Screeds - As the name would suggest, this screed dries at a quicker rate and allows you to use the screeded area much faster. The vast majority of the fast drying screeds are fibre reinforced and are appropriate for a wide array of projects where the swifter drying rate of three to seven millimetres is an advantage.
Self-Levelling or Liquid Screeds - A latex and cement formula which can achieve the highest standard SR1 finish. It is mainly needed to provide a smooth, clean floor over a damaged or poor quality substrate and enables all types of flooring materials to be used. Even with a depth of just 1mm, thewithin the screed provide a high strength surface for a wide range of uses.
Fibre Reinforced Screed - The professional's choice for domestic use over the top of underfloor heating. This is due to the improved strength and protection against thermal shrinkage and cracking offered by the special fibres within the screed mix. It sets at an identical rate to a standard screed, at about 1mm per day.
Polymer Screeds - A high strength flooring solution where a reduced thickness is essential.are available from a number of manufacturers and owing to their diverse chemical compositions have specific setting times for each individual product.
Industrial and Heavy Duty Screed - A screed that's designed for high load and heavy traffic areas where maximum strength and durability is very important.
SCREEDING PREPARATION AND INSTALLATION
To make sure that the screeding is of a good quality finish that's durable and hard wearing, time should be spent on fully preparing the area prior to any screed being poured. It's vital that all contaminants such as grease, oil, debris or paint is eradicated from the base before pouring any screed, because these can affect the bonding process that a good quality floor screed needs.
If any cleaning products were used during this stage it is crucial to make sure that no residues of detergents, soaps or other cleaning products are left on the floor surface and it is allowed to dry out naturally. At this stage any cracks need to be mended since these can easily travel up through a newly laid screed and be visible in the finished surface. An experienced Lostwithiel screeding contractor will take note of these problems during a on-site survey and make sure all preparations are completed before applying the next steps in the screeding process.
Before the screeding can be laid a damp proof membrane (DPM) must be put down to protect the final flooring and screed from moisture. There might be 2 or 3 layers of varying thicknesses of polythene to act as a barrier between the insulation layer and screed.
Another air-tight barrier could be needed if your home or business premises is in an area that's regarded as susceptible to radon gas. A simple airtightmight be sufficient in places with relatively low radon emissions, but in more severe situations there might need to be a more complex extraction system to block any ground penetrating radon gas.
Once the base has been prepared and any DPMs installed, a sealant or primer is then applied. A primer assists in the screed to successfully bond to the base surface and different types exist based upon which kind of screed is being used. These substances require trained technicians to apply them in the correct proportions by using tailor-made equipment, such as airless sprays.
Before any screed is laid, any underfloor heating will now be laid out. The heating pipes and wires are firmly mounted onto stop any movement and make certain they are positioned correctly. Underfloor heating is one of the most efficient ways to heat a room and a professionally installed system should provide even warmth across the floor area.
If you're not putting in under floor heating the screed will now be mixed and prepared on site and laid. Your proposed use of the room will help the screeding specialist on what kind of floor screed is perfect for your needs. For quick drying screeds there'll be at least twenty four hours delay before it can be walked on, and a further Three days minimum before you are able to install any flooring materials. Manufacturer's drying guidelines for heavy duty and standard screeds must be followed so as to achieve a quality finish and provide a stable and even floor surface.
The SR level of your screed can be checked once it's solidified sufficiently to be walked upon. The standard SR test involves the use of a 2m long straight-edge to check for any fluctuations in the screeded surface.
- SR1 - Over the entire floor area, if there aren't any deviations of more than 3 millimetres from the straight-edge, you've got a top quality SR1 specification surface.
- SR2 - If the floor surface deviates from the straight edge by 5 millimetres or less it is considered SR2 level and is the normal standard for commercial and industrial floors.
- SR3 - For utility floors where the quality of finish is comparatively unimportant SR3 is the specification and should have a maximum deviation measurement of ten millimetres or less.
If you require load bearing checks, a structural engineer is required to conduct the tests. The assessment will make certain that your newly laid screed is suitable for the load point requirements set down in the site survey. This will include what's known as a "drop hammer test" which records specific data on the strength and flexibility of the screed. Any screeding that has load bearing requirements must be sanctioned by a certified structural engineer heeding the BS8204 regulations.
