Floor Screeding Johnstone Scotland (PA5): If you are restoring a property or cellar, are hoping to install under floor heating or have a damaged or uneven floor in your Johnstone property, then it is time to consider hiring a professional floor screeder. A screed is used to generate a smooth floor surface over a concrete sub-base and provide a good foundation for you final flooring material. If you want your floors to last then a floor screed is one of the most important factors in any renovation or building task.
FLOOR SCREEDING COMPANIES JOHNSTONE
Having all the experience and know-how to help you achieve a perfectly finished floor in whichever shape or size of room you are working on, a reputable floor screeding company in Johnstone is the best choice for your floor screeding task. After a painstaking evaluation of your screeding project, they'll be able to inform you about which method of laying is most suitable for your circumstances, and what is the ideal type of screed to use.
The screeding contractor will also tell you if a structural engineer is required for your undertaking, to evaluate any load bearing, point loadings and flex strength that your screed floor may require to conform with current British Standards and building regulations.
The training and skills that a certified screeding technician brings to your project should guarantee a successful end result and help in prolonging the life of your floors. A correct mix of screed and the way it is laid is also vital to guarantee the final intergrity of your floor surface.
Before deciding upon a screeding specialist from those based in the Johnstone area, ask to what standard of finish they're basing their price quote, and also ensure you get multiple quotes. The SR (Surface Regularity) finish is the number to watch out for when receiving a quote from your Johnstone screeding contractor. Each of the 3 SR levels deliver different levels of finish, with SR1 offering the highest quality, with the lowest amount of deviation over the area of the floor. This means that you may have to correct any areas that might cause problems when putting down your finished flooring solution.
British Standards BS8204 sets down the guidelines and regulations that all Johnstone screeding companies is obliged to follow, and if using specialist screeding solutions, (Gypsol, Cemfloor, Flowcrete etc), they must be approved by the manufacturers as being skilled and trained in their use. A company holding such accreditation shows that they have been assessed and trained in using these products and can provide a high quality service in all areas of their installation.
Johnstone commercial screeders might be involved in screeding floors in factories, hospitals, schools, shops, pubs and warehouses.
TYPES OF SCREED
Standard Screeds - Widely used in residential flooring projects where the blend of sand and cement is ideal for standard floor traffic use. 5 parts sand to 1 part cement is the normal mixture for standard flooring screeds. The standard flooring screed will dry at a rate of 1mm thickness per day.
Advanced Drying and Fast Drying Screeds - If you have to press ahead urgently with the flooring on account of time restraints, this screed dries much faster than standard flooring screeds. Most of the fast drying screeds are fibre reinforced and are ideal for a whole host of projects where the quicker drying rate of three to seven millimetres is an advantage.
Industrial and Heavy Duty Screed - Where levels of traffic are expected to be high or heavy loading on the floor is needed, heavy duty screeds provide maximum durability and strength.
Liquid or Self-Levelling Screeds - When the highest possible standard of finish is needed this compound of cement and latex is employed to create SR1 level screeding. Primarily used to improve a poor substrate level or damaged floor in order to lay a brand new flooring surface, such as tiles over the top of it. These can be as little as 1mm thick, and because of the latex polymers, will still provide high strength.
Polymer Screeds - An extremely high strength flooring solution where a reduced thickness is essential. The setting times vary as outlined by product guidelines.
Fibre Reinforced Screed - The favoured choice by professional contractors for use with underfloor heating systems. The increased strength and flex offered by the fibres within the screed mix help protect the resulting floor from thermal shrinkage and cracking. It's got a drying rate of one millimetre per day.
SCREEDING PREPARATION AND INSTALLATION
Good preparation is essential for a quality finished screed surface that will be durable and hard wearing. Any paint, grease, debris and oil on the existing floor surface can affect the adhesion of the screed, and must be removed.
Any cleansing chemicals used in this stage should leave no residues, and the floor base must be allowed to dry by itself naturally. If screeding over a cement or stone floor then all cracks should be repaired to prevent them from "travelling" up through the screed layer and resulting in deviations on the final floor surface. An on-site survey will allow your Johnstone screeding contractor to highlight these preparation areas and finish them before beginning to pour the screeding.
A damp proof membrane (DPM) will be installed after the preparation work has been completed to prevent ground dampness getting into the screeding and floor materials. The damp proof membrane is made of thick polythene sheet and different layers could be used to act as a moisture barrier for the screed.
If your home is located in a place where radon gas is present a supplementary barrier layer is necessary to stop radon gas from seeping through. This can be just a simple airtight membrane, or in severe situations a ventilation system will need to be installed underneath the screeding to take away any inflow of radon gas from ground level.
As soon as the base has been prepared and any membranes installed, a primer or sealant is then applied. Sealers and primers assist with the bonding process and are specialist applications according to the sort of screed that is being applied. Because of their specialist nature, only experienced screeding contractors in Johnstone are capable of using them safely and correctly and using bespoke equipment for the task.
If you are installing underfloor heating, this is the time that it will need to be properly set out and installed. The underfloor heating system will be carefully positioned and mounted firmly on insulation panels to avoid potential movement during screed pouring process. Underfloor heating is one of the most efficient ways to heat a room and an expertly installed system should give an even warmth in all areas of the floor.
If you're not installing underfloor heating the screed will now be prepared in situ and laid. The specific requirements of the room will dictate the kind of screeding that's used. Bear in mind that even advanced and quick drying screeds have a minimum of twenty four hours before you are able to walk over any laid surfaces and a minimum 72 hours before any floor coverings can be laid. Manufacturer's drying instructions for heavy duty and standard screeds must be followed in order to achieve a quality finish and provide an even and stable surface.
As soon as the screed has set it can be checked for quality to establish the SR standard. Using a two metre straight-edge the floor surface is checked for any ridges, dips and deviations in the surface of the screed.
- SR1 - Over the whole area, if there aren't any disparities greater than 3mm from the straight-edge, then you have a top quality SR1 specification surface.
- SR2 - If the screed has a deviation from the straight-edge of 5 millimetres or less it is SR2 quality and is the normal standard for industrial and commercial projects.
- SR3 - SR3 is utility standard where a quality finish isn't required. This classification can have a maximum permissible deviation of 10 millimetres.
If you need load bearing checks, a qualified structural engineer is needed to carry out the testing. Using specialised equipment the structural engineer will verify the screeding strength and its suitability for use in a load bearing environment. This will include a drop hammer test which records specific data on the strength and flexibility of the screed. The precise testing and measurement tools mean that this can only be carried out by a qualified structural engineer respecting the British Standards BS8204 guidelines.

Coloured Floor Screeds
Multi-coloured screeds are a type of flooring material typically employed in commercial or industrial settings. To create a distinctive and decorative finish, coloured aggregates, resins, and sealers are blended together to form these screeds. Areas with machinery or heavy footfall commonly utilise them as they provide a long-lasting, durable and slip-resistant surface.
To match a business's branding or create a specific aesthetic in a space, multi-coloured screeds can be customised. Their ease of cleaning and maintenance makes them a sought-after option for facilities that demand a high level of hygiene. All in all, multi-coloured floor screeds provide both versatility and practicality as a flooring solution, making them a great option to add function and style to any commercial or industrial space.
Screed reinforcement improves the strength and durability of concrete screeds by reinforcing them. A base layer is covered with flat and thin layers of concrete, called screeds, to create a level surface. As flooring, they are frequently utilised in building projects, but they can also serve as a finishing layer for walls and ceilings.
To enhance the strength and prevent cracking of the screed, reinforcement materials such as steel mesh, wire or fibres are embedded within the screed mixture during the installation process. By distributing weight and load evenly across the surface, reinforcement improves its resistance to thermal changes, impact and abrasion.
To maintain the quality and structural integrity of screeds, it is essential to use screed reinforcement, resulting in a long-lasting and reliable surface for many different applications.
Granolithic screeding is a process of creating an even and smooth surface for floor coverings like carpets or tiles. It involves mixing cement, sand, and aggregate such as granite or marble chips to form a mixture, which is then applied to a concrete base. The mixture is levelled with a straight edge to give it a smooth, seamless surface.
The resulting flooring is easy to clean, slip-resistant and hard-wearing, making it ideal for use in areas with high foot traffic, such as shopping centres, schools and factories.
The granolithic screeding process involves preparation of the concrete base, mixing the screed mixture, laying the mixture, and giving it time to cure. Appropriate application and curing techniques are essential for the longevity and strength of the screed. The screed must be completely cured before any further flooring materials are laid.
