When it comes to laying liquid screed during the Winter you will always encounter a number of problems. Whilst laying screed in the colder months of the year is doable, if you are planning on starting a new project it is important to be prepared.

One of the biggest factors that affect liquid screed in Winter will always be the temperature. As temperatures can drop rapidly throughout the day you need to be prepared with the tools to maintain the temperature of your screed. If the screed cures and dries below the freezing point the water will freeze and drastically expand causing it to be unfit for use and the project will have to be scrapped. In order to avoid this, you will need to control both the ambient air temperature and floor temperature. Throughout the entire process, you will need to ensure the air temperature does not drop below 3 degrees Celsius and that the floor temperature is maintained at 5 degrees Celsius.

When initially transporting the screed materials i.e. cement, aggregates etc. you will need to ensure the bad weather isn’t able to reach them. Any moisture that reaches the materials will seriously affect the composition of the screed and cause it to not cure correctly when laid. To avoid this, sheets of polyethene should be used to cover everything during transport and storage.

Cold weather, unfortunately, will always increase the drying and curing times for screed but as mentioned, the screed must consistently be kept at a minimum of 5 degrees Celsius for the first five days. Again, polyethene sheets are an effective way of avoiding any cold or moisture entering the screed by keeping it warm enough to cure and dry. After a week the sheets should be removed for the screed to fully dry and any residual water can evaporate.

Although laying liquid screed in the wintertime has its challenges, by simply preparing and allowing an extended time frame for your project to ensure correct curing and drying, your liquid screed subfloor can be successful.

To the untrained eye, liquid screed and concrete can appear indistinguishable and it’s not hard to see why. The two are made from the same materials and use the same basic chemistry combining water, cement and aggregates. The elements which set these two apart is, in fact, the size of aggregates used, the grade of cement, the mix and finish consistency. The two are meant to provide very different results with concrete having a much coarser mix. As it contains much larger aggregates with a harder core, concrete can be much more durable and last longer than other materials.

This high strength found in concrete is one of the many reasons that it is used in the construction industry across the globe. It is the most commonly used man-made material in the world whereas Screed tends to be used in conjunction with concrete. Traditional screed is mostly a mixture of sand and cement mixtures that are blended on site and applied. The screed is then applied on top of existing concrete slabs as a finishing layer for indoor floors or as a means of levelling off the floor. The finishing cover of laminate, carpet, tile, stone etc. is then able to be applied on top.

As opposed to concrete, screed is used when a functional floor is required in the space or a specific floor type is wanted rather than a plain concrete floor. The type of screed applied will vary depending on the use such as how much traffic there will be, the location; whether it be commercial, residential or industrial. For indoor locations, liquid screed can be used to cover pre-installed heating systems or insulation for the property. Whereas with outdoor environments you will require a denser, more resistant polymer screed to withstand the elements and the different levels of traffic.

When it comes down to which is the better material between concrete and screed, there isn’t a straight answer. Each have their own unique properties and uses that can be applied to a number of flooring projects. It is important to shop around, do some research and ask an industry specialist for advice on which would best suit your upcoming project.

When it comes to Liquid Screed, every installation is different which means the drying times can vary. Factors such as the temperature and how many windows and doors you have in space are just some of the variables that will need to be considered.

Once the initial layer of screed has been applied, it should be left untouched meaning you cannot walk across it or place anything onto it for the first 48 hour. Throughout this time period all doors and windows should remain closed to allow it to dry quickly and evenly. Once the screed has completely solidified you should then begin to open the surrounding windows to allow moisture to evaporate, encouraging the final drying stages. It is at this point that you can begin walking across it provided it will only be minimal traffic; any high traffic areas will need added protection for a few days.

When Can You Begin to Apply Flooring?

Before you can begin installing the flooring of your choice you must ensure your Liquid screed has dried adequately and been approved by the installer. As an example, if you have let your Liquid screed dry on its own and it was 40mm deep, you would expect to wait 40 days before applying flooring.

Can the Drying Times Be Reduced?

The dry time of Liquid Screed can be reduced by implementing force dry techniques. Unlike cement-based screeds, Liquid screed can be dried using either a dehumidifier or an underfloor heating system. If you have had underfloor heating installed prior to the screed you can use this to decrease the drying time but only after the first week. Alternatively, you can choose to use several dehumidifiers, again, after the initial 7 days- something your installer will be able to provide at an additional cost.

Liquid screed (also known as flow screed) represents a modern alternative to more traditional sand and cement screed methods. It flows into any required shape to create smooth level surfaces and is easy to pour and quick to dry.  The simplicity and versatility of liquid screed make it increasingly popular for both residential and commercial developers, but when is it the right solution

Short on Time?

If you need to have your floor laid and ready for light foot traffic quickly, then liquid screed is the ideal solution for you. Its lay depth and liquid properties make it faster to apply and much quicker to dry than traditional sand and cement screed. Your floor could be ready for use in as little as 24 to 48 hours.

Are You Installing Underfloor Heating?

Liquid screed is ideal if you are looking to maximise the efficiency of an underfloor heating system. With nearly twice the thermal conductivity of traditional screed, this method makes for reduced energy consumption and improved effectiveness, not to mention saving you money on your power bills.

Quality Finish

If you’re looking for a high-quality finish with minimal fuss, liquid screed is the best option for you. It will flow into any required shape and will fill all gaps and voids to improve the surface regularity.  It’s also resistant to curling and cracking, making it a durable alternative to cement or sand screed. Your floor will have a smooth and even finish that lasts.

People are choosing underfloor heating as a better alternative to traditional radiators. With rising energy bills, heated floors are a more attractive option as they consume less energy. Although the method of underfloor heating used today is relatively new, the idea has been around for ages.

Here’s our guide to the amount of energy used by heated floors.

Energy Costs for Heated Flooring

Due to the age and type of building, every project has unique space heating needs. Whether your underfloor heating is electrically powered or water powered will affect the energy consumed and therefore the cost.

According to the Centre for Sustainable Energy, ‘when combined with a condensing boiler, underfloor heating can achieve energy efficiencies of over 90%.’ With your gas boiler, you can save up to 30% more energy than radiators. With a condensing boiler, further savings depend on whether you have a cheap gas supplier.

Energy Savings from Underfloor Heating

When run from a heat pump source, the saving improves to 40% with underfloor heating. Although installation costs are more, you can recoup your investment through energy savings.

Another aspect of energy usage is monitoring. Through a smart timer and thermostat, you get exact control over usage. Now you can arrive home and enjoy warm winter feet on demand.

Variables That Impact on Heated Floors

Many factors can impact on energy usage such as whether a new build, renovation or commercial project. Older buildings with limited wall and ceiling insulation have more draughts.

For new buildings, heated flooring can be included as part of the overall design. That’s because up-to-date building standards lead to better performance. Of course, energy tariffs also influence running costs and your return on investment.

How Much Does It Cost To Screed A Floor

During the development of any building, the application of floor screed is one of the most important stages of laying a new floor. Screed is a mixture of sand, water, cement and other sand-based aggregates, which helps to create a sturdy, even layer of flooring – a perfect base for any flooring finish. But how much does it cost to screed a floor?

Factors Affecting the Cost of Floor Screed

There are factors that should be considered when pricing a floor screed project. These include:

• Type of screed used
• Quality of the screed
• Depth of screed required
• Overall size of the floor
• Accessibility
• Drying and trafficking time of the screed
• How many people are working on the project
• Geographic location in the UK

Due to these factors, it can be difficult to get an exact figure from an online calculator. However, while there are many variables, it helps to have a general figure to use when you are planning your project. Look at this rough guide:

• Traditional screed costs between £11 and £14 per square metre, based on a thickness of 75mm covering 125 square metres per day.
• Flow screed costs between £10 and £16 per square metre, based on a thickness of 50mm covering up to 1,500 square metres daily.

Residential and domestic customers across the UK are investing in heated floors for all kinds of reasons. When you install a heated floor, you can benefit in a variety of ways and gain more enjoyment and comfort from your home or business premises. Heated floors and underfloor heating feel great to walk in and ensure heat is distributed evenly around your space. When you have underfloor heating in place, you can stop relying on radiators and can use the space for artwork, units and much more.

Barefoot Luxury

Many homeowners find themselves walking around their homes barefoot thanks to the luxurious warmth offered by underfloor heating. Your underfloor heating solution can even help you reduce your fuel bills. This is because it works at a lower temperature than a radiator. You will also lose less warmth when your windows are open or when you’re faced with draughts once you have made your investment. Your heating solution can even help you add value to your home and result in a higher price being paid for it should you ever decide to sell up.

A Modern, Inviting Look

Another key advantage of underfloor heating is that it is invisible, which is ideal for those opting for a minimalist look as well those people who don’t want radiators compromising the aesthetic appeal of their space. You can even install heated floor systems underneath carpets as well as floors made from tiles, wood and stone.

Liquid Screed Problems and how to avoid them

Whilst offering many benefits to traditional floor screeds, you may also hear of liquid screed problems occurring in certain situations.

It’s fair to say, you will be pretty unlucky to have a problem with liquid screeds, and are more likely to have a problem with more traditional methods, but with so many different applications and environments, you need to know it can happen and why.

Liquid screed problems happen in 3 areas

When liquid screed problems occur, it will generally fall into 3 problem areas; at the planning stage of the construction; during the application and installation stage; or at the curing and drying stage.

At the planning stage, everybody needs to be very clear on the timelines for the installation including planning the installation of an underfloor heating system, any Damp Proof Membranes (DPM) and in working out timeframes to allow for correct curing and drying times.

Having an expert plan your liquid screed installation is vital to avoid any such liquid screed problems. You must choose the right partner, one with a proven track record and ability to deliver a successful solution, and one that can work closely with the main contractor.

Again, if you have chosen your provider correctly, the installation should be a simple and effective task. Get it wrong and you can face issues ranging from cracking, uneven and damaged surfaces or even a weak floor screed due to incorrect screed depths. If the pre-installation work and specification is not perfect, these liquid screed problems can occur.

Special care must be taken when working with DPM’s and underfloor heating systems to ensure no creases or gaps are present which will lead to weak points. A expert liquid screed contractor will ensure all this preparation is completed correctly before work is started, then check everything as the installation progresses.

Finally, the curing and drying stage must be performed exactly as recommended by the liquid screed contractor. Nothing should effect this final stage. Other trades must not interfere or attempt to accelerate or deviate from the original plan and specification.

For example, things like testing the underfloor heating systems should not be done until well after the cure time has elapsed, ventilation should be maintained as per the original plan. The liquid screed will have been installed around the existing environment, so changing anything would potentially effect the drying process, leading to liquid screed problems.

UK Screeds Ltd have been providing liquid screed floors across most of the UK since 2002 and are the partners of choice for many well-known construction companies, trusted to do the job right each and every time. Our consultants offer expert advice and planning to ensure your project is completed perfectly.

Liquid floor screed verses traditional floor screed

We are often asked, “which is the best? liquid screed or traditional sand cement floor screed”. Our answer in most cases will be liquid floor screed of course, but let’s explain why in more detail.

Installation and drying times

With any building project, the speed of installation is one of the vital issues. Installing a liquid floor screed is always going to be faster, but more importantly, the drying times are really fast in comparison allowing the project to move forward more quickly.

BS8204 states that standard screed drying times should be 1 day for every 1mm thickness, so a 50mm standard screed will take 50+ days to dry. Compare this to a liquid floor screed which in almost all cases can be walked on after 24 hours and force dried in under 7 days.

This alone saves project delay and planning times allowing trades to work very quickly after the installation, allowing completion dates to be reduced, saving vast sums of money – time is money after all.

Overall thickness of floor screed

A traditional screed is generally installed as a thick layer to ensure no cracking or shrinkage occurs when dry. In comparison, liquid floor screed is generally a much thinner layer of material and due to its make-up, is stronger and more durable.

The other advantage of being a thinner layer is that the floor insulation layer can be thicker and so, therefore, more efficient in the long run.

Higher efficiency in underfloor heating systems

When installing underfloor heating systems, liquid floor screed is vastly superior compared to standard screed. As the liquid screed is poured, it completely surrounds the heating tubes so no air gaps are present, thus conducting the heat more efficiently.

Traditional screeds can never surround the tubes as effectively, so heat transfer will be less efficient and overall the running costs of any underfloor heating system will be higher than when a liquid screed floor is installed.

Cost comparisons

Standard screed materials and labour costs are arguably cheaper, however, you really need to think about the bigger picture of the overall project costs rather than the unit cost per square meter. Yes on paper liquid screed will almost certainly work out more expensive but in the overall project it will work out more cost effective and help keep timelines for the project to a minimum.

Is underfloor heating right for me?

We are often asked about underfloor heating systems and of course, the ideal time to install one is when we are pouring the liquid screed flooring. So here are the most common questions and answers which will help you make the decision.

Do I need a special boiler or heating source?

No, the underfloor heating systems we provide use pretty much any existing gas LPG or oil-fired boiler as well as using heat pumps. The main thing is that the boiler must be reliable and regularly serviced.

Which underfloor heating systems are the best?

It is widely recognised that wet underfloor heating systems are the most effective and cheapest to run, install, and has little or no maintenance requirements. We install small pipes in the liquid screed which carry the water from the heat source around the floor.

How effective are underfloor heating systems?

This does vary from building to building and will depend on lots of factors, but it is common to see savings of 30 – 40% on traditional radiator systems. Underfloor systems are designed to be cheaper to run more controllable and more effective than other systems.

When switched on, how long does it take to warm up?

Underfloor heating systems warm up very quickly and can soon raise the temperature of the room. This is because it is very effective and uses the conductivity of the screed and the floor covering to radiate the heat. Stone and tiles are the most effective and will warm up the fastest, with carpet taking a little longer.

Where can underfloor heating be used?

Underfloor heating systems can be installed all over the building, including the upper floors, so it is a versatile and discrete way of heating a property – no ugly pipes and radiators to be seen. Wet rooms, bathrooms, and kitchens are the most common places to install systems but when building a property from scratch, it is now becoming a system of choice.

How long will it last and what if it goes wrong?

Our systems are designed and tested before being installed in the liquid screed flooring, so it is highly unlikely a problem will occur. The pipes are designed to last more than 50 years as a minimum and the pipes are a continuous single section without joins. If a leak is detected, this can be simply repaired, but it is very rare.

What are the maintenance plans?

Underfloor heating systems are designed to have no maintenance; however, the boiler and pumps will need to be regularly serviced (as with any system) to make sure they are working efficiently. If you take a system from us, we are always available to offer any advice and ongoing support.

We hope this will answer some of your questions. We are always available to speak to you and advise on the best solution and design the most effective systems for your property.
