High-Performance Screed for Your UFH Project
If you’re installing underfloor heating for a Kent renovation or self-build, the floor is the absolute foundation of your comfort. The team at Capital Screeding are Kent’s specialist UFH liquid screed contractors. We don’t just supply material; we ensure your underfloor heating works at its optimum capacity.
The boiler and pipes are only half the story – the screed is the real engine of thermal delivery. We offer a direct supply-and-fit service that prioritises fast heat-up times and a flawless finish. By managing both the product and the pour, we deliver a floor tailored to your project’s specific thermal needs and local site conditions.
Maximising Heat Transfer – Why the Right Pour Matters
Your boiler and pipes generate the warmth, but the screed is what actually drives that heat into your home. On sites across Kent, we often see installations underperforming where traditional sand and cement screed has been used. This is because it’s too coarse to hug the pipework. If the screed isn’t wrapped tightly around those pipes, you’re losing heat before it even reaches the surface.
Liquid screed is different. Because it’s a fluid, which means it flows naturally, achieving 100% encapsulation of your heating pipes. This eliminates the ‘air gaps’ that act as unwanted insulation, trapping heat under the floor rather than letting it into your room. By removing these pockets, we ensure the heat moves directly from the water in the pipe into the floor mass, significantly improving your thermal conductivity.
Why the Pour Changes Everything:
Total Encapsulation – Liquid screeds elimination of air gaps means the heat has a direct path to the surface.
Faster Response Times – A thinner, denser pour means your house warms up in minutes, not hours.
Flat Finish – A level floor ensures your final finish – whether tile or LVT – sits flush, preventing cold spots caused by uneven thickness.
Lower Energy Bills – When heat moves more efficiently, your boiler or heat pump doesn’t have to work as hard.
Liquid Screed Timelines and Drying
At Capital Screeding, we care as much about your build schedule as we do about the pour itself. Liquid screed can actually offer you a much faster route to your final floor finish than other options, and here’s why. Because our liquid mix is so thermally dense, we can often pour it significantly thinner than traditional 65mm+ sand and cement beds. Thinner screed means less water in the building, so your schedule doesn’t have to grind to a halt.
We coordinate the delivery and the install to ensure the ‘wet’ part of the job is over fast, so you can get back on site.
- Rapid-Fire Installation – We can pour a typical ground floor in a matter of hours.
- Back on Your Feet – You won’t be off-site for long. Our floors are usually ready for light foot traffic within 24 to 48 hours, so you can get back to work.
- The 7-Day Force Dry – Liquid screed can be ‘force dried’ using your UFH system just seven days after the pour.
- Ready for Finishes – Because it’s a precision product with minimal shrinkage, you get a dead-level surface that’s ready for tiles or LVT far sooner than a standard floor.
- No Blame Game – Since we are your Kent-based supply-and-fit team, we manage the process from start to finish. We take total responsibility for the quality of your sub-floor.
Your Liquid Screed Questions Answered
Here are the four questions we get asked most often when we’re out surveying sites in places like Sevenoaks, Maidstone, and Canterbury.
You really don’t need a massive site to justify a liquid screed install. While there is a minimum setup cost, the benefits in a high-traffic area like a kitchen are actually higher. Because we can pour thinner, you save on floor height – which is usually at a premium in Kent renovations where you’re trying to match new floors to existing ones. We regularly handle smaller domestic pours; as long as we can get our transit-sized pump near the property, no job is too small for a high performance floor.
Laitance is a thin film that can form on the surface as the screed cures. Not every mix produces it, but if yours does, you will need to sand it off before you lay your finish – usually about 7–10 days after the pour, ensuring the surface is perfectly keyed and ready for your floor fitters. If you don’t, your tile adhesive or LVT glue won’t bond, and your floor will eventually fail.
Liquid screed is actually the best partner for an Air Source Heat Pump (ASHP). Traditional boilers blast heat, but ASHPs work most efficiently at lower flow temperatures. Because our screed has such high thermal conductivity and zero air gaps, it doesn’t need the water to be nearly as hot to warm your room.
We can often pour our specialist mixes as thin as 35mm to 40mm (with a minimum of 25mm coverage over the pipes). That extra 30mm of saved head height can be the difference between a room feeling cramped or spacious. We’ll calculate the exact depth needed during our site visit to ensure you get the thermal mass you need without wasting a millimetre of space.
Start Your Kent Project Right
Your underfloor heating is only as good as the screed that’s poured on top of it. We’re here to make sure that investment pays off. Whether you’re at the planning stage or ready for the pump to arrive on your driveway, contact us to get the job done by Kent’s trade specialists – 020 3369 3396
