Hey everyone, and welcome back to my channel! Today, we’re diving into the world of underfloor heating, specifically focusing on the crucial element of screed.
Whether you’re a seasoned DIY enthusiast or just starting out, choosing the right screed material and understanding the intricacies of pouring it can make all the difference in the success and efficiency of your underfloor heating system.
In this video, we’ll explore the various types of screed available, their pros and cons, and help you determine which one best suits your project. We’ll also delve into the specifics of pouring screed, covering essential aspects like mixing ratios, leveling techniques, and curing times.
So, if you’re ready to get your hands dirty and learn everything you need to know about screed for underfloor heating, then let’s get started!
The screed for underfloor heating is a special type of screed that is designed to be used with underfloor heating systems. It is typically made from a mixture of cement, sand, and water, and it may also contain additives such as fibers or plasticizers. The screed is poured over the underfloor heating pipes, and it helps to distribute the heat evenly throughout the floor.
There are two main types of screed for underfloor heating: traditional screed and liquid screed. Traditional screed is a wet mix that is poured and leveled by hand. Liquid screed is a self-leveling mix that is poured and then allowed to flow into place.
The floor should be level and free of any debris before the screed is poured. The underfloor heating pipes should be properly installed and secured. The screed should be poured to the correct thickness, and it should be allowed to dry completely before the floor is covered.
It is possible to pour the screed for underfloor heating yourself, but it is important to follow the manufacturer’s instructions carefully. If you are not confident in your ability to do the job correctly, it is best to hire a professional.
Semi-dry screed is a type of screed that is made with a lower water content than traditional screed. This makes it easier to work with and it dries faster. Semi-dry screed is also less likely to crack than traditional screed.
The screed for underfloor heating is an important part of the underfloor heating system. It helps to distribute the heat evenly throughout the floor and it protects the underfloor heating pipes. It is important to choose the right type of screed for your needs and to follow the manufacturer’s instructions carefully when pouring the screed.

When installing electric heating, it’s crucial to choose the right type of screed. Traditional cement-based screeds can take a long time to dry, which can delay the installation of your heating system. A faster option is to use a Knauf ready-to-use dry mix. This type of screed dries much quicker, allowing you to install your heating system sooner.
The thickness of the screed layer will depend on the type of flooring you are installing. For water flooring, the screed layer should be at least 50mm thick. For tiles, the screed layer should be at least 35mm thick.
Before pouring the screed, it’s important to arm the floor. This involves laying a mesh of steel reinforcement over the insulation layer. The mesh will help to prevent the screed from cracking.
When pouring the screed, it’s important to follow these rules:
- Mix the dry mix with water according to the manufacturer’s instructions.
- Pour the screed evenly over the floor.
- Use a screed rule to level the screed.
- Allow the screed to dry completely before installing your flooring.
By following these tips, you can ensure that your underfloor heating system is installed correctly and will provide you with many years of warmth and comfort.
