Liquid Screed Information

About Liquid Screed

Our Liquid Screed can be used in almost any application of either new build or property renovation projects, and especially excells in rooms that are not a traditional shape as it can flow to whatever shape floor you wish. It’s suitable for both commercial and residential applications. It's been installed in almost all types of building including hotels, schools, hospitals, shops, airports and family homes etc.

Liquid Screed Depth Options

Our Liquid Floor Screed can be laid at shallower depths than traditional screed which has a whole range of advantages:

  • Less height can result in the liquid screed being a more cost effective alternative than sand and cement due to the fact that less product is required.
  • The reduction in depth usually means that the screed is ready for final floor finishes in much less time than a traditional screed.
  • Lower depths of screed will make our Under Floor Heating system more responsive during both heating up and cooling down cycles as they have less screed surrouding them


Liquid Screed Strength

At Speed Screed, our liquid screed can achieve an in industry standard strength of "C30 N/mm squared". We are also able to supply and install 'extra strength screed floors' that can achieve "C35 through to C40 N/mm squared" Please contact us today for further details if you have a specific strength requirement for your project.

Installation Methods

The liquid screed will be delivered in a large mixer truck and Speed Screed installation engineers will use a pump to lay the product at an installation rate of approximately 5 minutes per meters cubed. The finished surface will then be dappled with a T-bar tool to remove any air bubbles and produce a smooth surface for the final finish.

Until the screed has fully hardened, you’ll need to ensure the surface is protected from direct sunlight, water, and severe draughts. After three days it is recommended that doors and windows are opened to assist with drying and the further release of moisture.

Our Service

Our service includes a site visit to advise you on preparations, we can assist as required. Prior to ordering the liquid screed we will do a final visit to ensure that the floor areas are properly prepared and all of our levels are in place.

We will discuss and advise you on the following

  • Liquid Screed products available
  • Insulation depth
  • Polythene membrane
  • Preparation
  • Material Quantities and costs

Liquid Screed Floors & Under Floor Heating

Almost all types of screeds and concretes can work with under floor heating installations, however the under floor heating will give very different results depending on the type of screed floor which has been used, and the depth of the screed or concrete.

As a general rule, the thicker the screed or conrete floor being used, the longer the delay in both warming up and and cooling down of the under floor heating. Both under-heating and over-heating can result from getting this calculation wrong, so it’s important that the correct amount, and correct type of screed is used.

At Speed Screed, we would generally recommend a Liquid Flowing Screed for under floor heating as all the evidence suggests that the heat output is optimised in every way: Everything from the flexible installtion options to the warm up and cool down time.

Preparation Advice & Options

Before any type of screed is installed into your property, an amount of preparation is required to ensure a perfect finish. The preparation needed will vary from property to property, but as a rule of thumb, the following will be required in this approximate order from the ground up:

  • A Damp Proof Membrane (DPM)
  • Slab
  • Insulation
  • Vapour Barrier
  • Finally followed by the Liquid Screed of your choice

  • Depending on your property, Speed Screed can also complete the preparation and installation on upper floors (using either a concrete plank or a beam and block construction). On upper floors within a property, you will generally not need to install a "Damp Proof Membrane", however the ‘Vapour Barrier’ is usually still required. (This is because the vapour barrier is required by the insulation manufacturers, to prevent contamination from the screed).

Get A Perfect Finish Every Time

Essentially the flatter the finished floor is, the easier it is to lay floor finishes such as wood and carpet. Liquid screed is far superior in this respect.
