What Is Liquid Screed Made Of?

Many of RB Liquid Screed’s contractor clients are now telling us that, having used liquid screed once, they could never go back to traditional or ‘dry’ screed. They cite the quick drying times, the speed of application and the great finish which is guaranteed. In the highly competitive construction industry, innovative products that shave time off schedules are going to get adopted pretty quickly.

Where liquid screed is used for wet underfloor heating installations it also gets a big thumbs up from homeowners. They love the even heating that’s achieved as a result of the enhanced thermal conductivity. They’re also delighted to be able to heat using lower water temperatures, which saves them money on their bills!

Here’s our comparison, which asks ‘what is liquid screed is made of?’, considers the composition of cement screed, and sees how each of the ingredients produce very different results.

What is Traditional Screed Made Of?

The dry screed mixture has stood the test of time for over a century now. It’s made of just sand, cement and water. The screed is mixed manually and the ratio of the three components changes slightly in response to environmental conditions. Normally, however, 4 part sand to 1 part cement is the standard measurement.

  • Traditional screed is ideal for use in building such as warehouses where an exposed floor is required.
  • The manual mix leaves a greater potential for error in the mix. Too wet and the screed may never dry unevenly; too dry and it could lead to cracking.
  • Concrete screeds have a larger carbon footprint than flow screeds.

What is Liquid Screed Made Of?

Flow screed, also known as anhydrate screed, uses a binding agent called calcium sulphate in place of cement. Once the water is added to the mix it sets off a reaction in which gypsum is formed. The reaction lasts for around a week until the calcium sulphate is completely used up. The result is an extremely durable sub-floor.

  • Liquid screed can be poured onsite at a rate of 2,000 square metres in a day.
  • Anhydrate screeds do not curl, crack or warp.
  • The floor is normally dry enough for light foot traffic after 24/48 hours.
  • Liquid screed has such great eco-friendly credentials that it’s known as ‘green floor’.
