TYPES OF SCREED
Standard Screeds - A mixture of sand and cement which is okay for basic domestic use. The standard screed is a mix of 5 parts sand to one cement. This five to one ratio standardwill dry out at a rate of just 1mm per day after application.
Fibre Reinforced Screed - The favourite choice of professional installers for use in combination with underfloor heating systems. This is due to the increased strength and protection against thermal shrinkage and cracking provided by the fibres within the screed mix. At roughly 1mm per day, it has an identical setting rate to standard screed.
Liquid or Self-Levelling Screeds - A latex and cement solution which can achieve the highest standard SR1 finish. This self-levelling compound provides a smooth and level surface over a damaged floor or rough substrate to enable all types of flooring materials to be laid. These can be as little as 1mm in depth, and thanks to the latex polymers, will still provide high strength.
Industrial and Heavy Duty Screed - A screed designed for high load and heavy traffic areas where maximum durability and strength is very important.
Advanced Drying and Fast Drying Screeds - If you have to use the area as soon as possible a fast drying screed might be a good choice. The majority of the fast drying screeds are of thekind and are suitable for a wide variety of flooring projects where the quicker curing rate of 3-7mm is advantageous.
Polymer Screeds - These provide an extremely high level of strength with a minimal thickness. Manufacturer's guidelines for curing times differ across the product ranges.
SCREEDING PREPARATION AND INSTALLATION
Screeding companies will have to prepare the area prior to any other work in order to ensure a hard wearing and quality screed flooring. The original floor surface should be thoroughly cleaned to eliminate any oil, paint, grease and debris that might adversely affect the adhesion of the screed.
If cleansing products were used it's crucial to remove any traces of soap, detergent etc, and leave the floor surface to dry naturally. If screeding over a cement or stone floor all cracks should be mended to prevent them from "travelling" through the screed layer and producing imperfections on the finished floor surface. An on-site survey will enable your Thirsk screeding company to pinpoint this preparation work and tackle it before beginning to apply the screed layer.
Before any screeding can be laid a damp proof membrane (DPM) must be installed to shield the final flooring and screed from dampness. Different thicknesses of polythene sheeting could be used as a damp proof membrane and also act as a barrier for the screed and any insulation material.
An additional airtight barrier could be necessary if your building is in a location that's known to be prone to radon gas emissions. This could be as simple as an air-tight membrane, or in severe situations a ventilation system will be installed underneath the screed to draw out any influx of air and gas from the ground.
As soon as the floor base has been prepared and all membranes installed, a primer or sealer is then applied. These primers and sealers will make sure the screed bonds properly to the floor base and help to accomplish a top quality finished floor. These products need professional tradesmen to apply them in the right ratios by using custom-made equipment, such as airless sprays.
Under floor heating can now be laid out, installed and tested before the screed is applied. The underfloor heating system is laid out in the correct pattern and attached firmly to insulation panels to avoid any movement during screed pouring process. Under floor heating is one of the most efficient ways to heat a room and a properly installed system should give an even warmth all over the floor.
Naturally, if you aren't installing underfloor heating, you can just ignore this stage and get on with applying the floor screed. Your use of the room will assist your screeding company on which kind of screed is ideal for your requirements. After application of the screed there's at least twenty four hours (for quick drying and advanced screeds) before you're able to walk upon the surface, and a seventy two hours minimum curing time for any floor material installation. This timescale is increased for heavy duty and standard screeds and the manufacture's instructions should be followed to the letter to produce the optimal finish and longevity of the floor.
Once the screed has set it can be checked for quality to verify its SR standard. The test involves the use of a 2m straight edge laid on the surface and any fluctuations from true are calculated.
- SR1 - Disparities of 3mm or less as measured across the whole floor area shows your screeding to be of the finest quality and categorised as SR1.
- SR2 - SR2 is for normal standard industrial and commercial floors and can deviate from the straight-edge by up to five millimetres.
- SR3 - For a utility area or room where the finish is relatively unimportant SR3 is the specification and should have a deviation measurement of 10 millimetres or less.
If you need to check the screeded floor for load bearing, a structural engineer is necessary to conduct the tests. This assessment will ascertain the strength of the screeded surface and the viability for its proposed use. An assessment called the "drop hammer test" will be performed at various areas on the screed layer and the outcomes noted. The specialist measurement and testing tools needed mean this can only be carried out by a qualified structural engineer obeying the British Standards BS8204 guidelines.

When the characteristics of your floor's surface means that a level of flexibility is required, it may be advantageous to apply a latex self-levelling screed, as opposed to one with a more rigid finish. Latex screeds normally comprise two parts - a cement-based powder, and a liquid latex mixture. Whereby water is normally used in a screed mix, this is replaced with the liquid latex, making it quicker drying and more flexible than other standard screeds.
Used in the levelling of sub-floors, this latex compound provides a suitable surface for the installation of the final floor finishes. Appropriate for sub-floors of sand/cement, wood, asphalt, concrete and quarry tiles, this screeding gives the ideal surface for the application of flooring adhesives that is durable and smooth. Even where there happens to be a bit of movement in your sub-floor, this type of screed will provide a flexible, crack-free finish.
Latex screeds are not a suitable choice where "floating" screeds are needed, for example when an unbonded screed is being laid on top of a membrane of either acoustic or thermal insulation, such as may be the case when you're screeding over underfloor heating, and screed depths of 50mm-75mm may be necessary.
