The use of liquid screed is gaining popularity over traditional sand and cement screed. In this article, we will explore the reasons why liquid screed is a better option and why you need to consider it for your upcoming project.
WHAT IS LIQUID SCREED & WHY IS IT BECOMING SO POPULAR?
Liquid screed, also known as flowing screed, is a mixture that is applied by pumping it directly onto the surface to be levelled. The two primary types of liquid screed are anhydrite screed, made from a blend of sharp sand, water and anhydrite binder, then there’s cementitious screed, which consists of cement, binders, water and sharp sand.
The use of liquid screed has become increasingly popular, mainly because it is applied in liquid form instead of being semi-dry like traditional screed. This allows it to be applied at a much faster rate, typically covering 500-1000m2 per day and, with some products, up to 2000m2 in a single day. By contrast, traditional screed is typically applied at a rate of only 100-150m2 per day, demonstrating a significant difference in application speed.
THE BETTER CHOICE FOR FLOORS WITH UNDERFLOOR HEATING SYSTEM
Underfloor heating systems are ideally suited for use with liquid screed. While traditional screed can also be used with underfloor heating, it may sometimes leave air gaps which can impact the effectiveness of the system. Because of its liquid consistency, flowing screeds can wrap seamlessly around the system and eliminate any air pockets.
THE BENEFITS OF LIQUID SCREED OVER TRADITIONAL SCREED
- Faster application: Liquid screed can be applied much faster than traditional screed, with a coverage of up to 2000m2 in a single day, which makes it ideal for large-scale projects.
- Better for underfloor heating: Liquid Screed is ideal for use with underfloor systems, as it is able to wrap around the system without leaving any air gaps, ensuring optimal performance of the heating system.
- Reduced drying time: Liquid screed dries faster than traditional screed, this is mainly due to the thickness of liquid screed being thinner.
- Less wastage: Liquid screed comes ready-mixed, which reduces wastage and makes it more environmentally friendly.
THINGS TO CONSIDER BEFORE USING LIQUID SCREED
While liquid screed has many advantages over traditional screed, there are some potential drawbacks to consider as well. Here are some cons of liquid screed:
- Cost: Liquid screed can be more expensive than traditional screed due to the use of specialist binders and the need for specialized equipment to install it.
- Falls: It can not form falls or ramps as it is a liquid and therefore flows to one level.
- Temperature sensitivity: The temperature and humidity levels during installation can affect the performance and drying time of liquid screed, which may require additional time and resources to control.
Overall, liquid screed offers numerous advantages over traditional screed, making it a popular choice for many construction projects. However, it is important to consider these potential drawbacks before deciding if it is the right choice for your specific project.
