TYPES OF SCREED
Standard Screeds - Frequently used in domestic projects where the blend of sand and cement is acceptable for basic footfall usage. The standard screed is a mixture of 5 parts sand to one of cement. This five to one ratio standard flooring screed will set hard at a rate of just 1mm per day after application.
Polymer Screeds - When a reduced thickness of floor is necessary due to building requirements, a polymer screed offers an extremely high strength solution to the problem. Maker's guidelines for drying times are different across the product ranges.
Fibre Reinforced Screed - Used with under floor heating and is the recommended option in these projects. The greater strength and flex provided by the special fibres within this screed help protect the floor from shrinkage and cracking due to heat. The screed will set hard at a rate of roughly 1mm/day.
Self-Levelling or Liquid Screeds - Used to provide a high quality finish, especially in SR1 levels of screeding, by a latex and cement formula. It's mostly used to produce a high quality floor over the top of a poor quality or damaged substrate and results in a finish onto which all sorts of flooring materials can be laid. They can be as little as 1mm in depth, and because of the latex polymers, will still provide high strength.
Fast Drying and Advanced Drying Screeds - As the name suggest, this screed dries rapidly and allows you to use the floor area much sooner. Drying at a rate of 3-7mm/day, determined by the mix, they are normally a fibre reinforced type of screed and are suitable for projects which have tight schedules.
Industrial and Heavy Duty Screed - Where levels of traffic are expected to be high or heavy loading of the floor is required, heavy duty screeds deliver maximum durability and strength.
SCREEDING PREPARATION AND INSTALLATION
Preparation is essential for a quality finished screed surface that will be hard wearing and durable. The original floor surfaces should be thoroughly cleaned to eliminate any debris, oil, grease and paint which might adversely affect the adhesion of the screeding.
Any cleansing chemicals used in this phase shouldn't leave any residues, and the floor surface must be allowed to dry by itself naturally. If screeding over a cement or stone floor all cracks should be repaired to prevent them from "travelling" up through a screed layer and causing imperfections on the finished surface. During an on-site survey your St Helens screeding company will notice what preparations are required before any actual screeding commences.
To protect the screeding layer and flooring materials from moisture rising up from the ground, a damp proof membrane (DPM) must be laid. There may be two or three layers of different thickness polythene to act as a barrier between the insulation layer and screed.
A supplementary air-tight barrier might be necessary if your house is in a location which is regarded as prone to radon gas. A simple airtight membrane might be enough in places with low levels of radon, however in more severe situations there might need to be a more sophisticated ventilation and extraction system to take away any ground penetrating radon gases.
As soon as the floor base has been prepared and all DPMs installed, a sealer or primer is then applied. These sealers and primers will ensure the screed bonds effectively to the base and help to create a top quality finished floor. These products need qualified tradesmen to apply them in the right proportions by using custom-made equipment, such as airless sprays.
Now is the time that under floor heating can be laid out in the correct manner and installed. The cables and heating pipes are firmly attached to insulation panels to stop any movement and make certain that they're laid in the correct position. Warmth is spread evenly across a floor area in an expertly fitted under floor heating system, and with it being an efficient choice of heating, it's an ideal choice for the majority of St Helens home renovation projects.
If you aren't putting in under floor heating the screed can now be prepared on site and poured. Your proposed use of the room will assist your screeding contractor on what kind of screed is right for your requirements. Bear in mind that even quick drying screeds have a minimum of twenty four hours before you're able to walk on any laid surface and at least 72 hours before any flooring can be applied. If you're using standard or heavy duty screeds the drying time is increased and the manufacturer's guidelines must be followed in order to get the best possible finish for your floor.
The SR level of your screeding can be checked once it has set enough to be walked on. The standard SR test uses a 2m straight edge to check for any fluctuations in the floor surface.
- SR1 - SR1 is the highest standard and allows just three millimetres of deviation from the straight-edge.
- SR2 - SR2 is the classification for normal standard floors in industrial and commercial projects and can deviate from the straight-edge by up to five millimetres.
- SR3 - If the deviation is 10 millimetres or less the screeding quality is classified as SR3 and is suitable for garage and utility areas.
If your screeding has been installed with specific load bearing requirements in mind then a structural engineer is going to be necessary to conduct tests. This test will determine the overall strength of the screeding and the viability for its proposed use. The screed could be given a drop hammer test to measure flexibility and strength at distinct points. The specialist measurement and testing tools needed mean that this can only be undertaken by a competent structural engineer applying the BS8204 guidelines.
