As of October 2017 Mixamate now offers a brand new Liquid Screed service! Liquid screed can offer a hassle free, cost-effective alternative to traditional dry screed products. We’ve teamed up with Gypsol, one of the UK’s leading liquid screed formulas, to provide the highest standard of liquid screed available on the market today. What’s more, our all-in-one Screed Pumping Truck is capable of the delivery, mixing, and pumping of screed from a single vehicle, which greatly reduces the headache associated with these kinds of jobs.

“Liquid screed is something we are being asked for increasingly this year,” said Chris Smith, Managing Director for Mixamate. “It comes with certain advantages over sand and cement screed, particularly with the growing popularity of underfloor heating. If people want the option for liquid screed we can deliver any amount from 2m3. Both this new product and our traditional screed mixes can be administered through our all-in-one pumping machines, this dramatically reduces the hassle associated with this type of work.”

Advantages of using Liquid Screed

  • Can be administered more quickly than traditional mixes
  • Requires less labour
  • Offers thinner and more conductive making it perfect for underfloor heating
  • Additives like fibres can be added to the screed

Additional information – Liquid Screed Description

  • It is designed to offer a smooth flat and level surface for use in the vast majority of interior non wearing applications were a subsequent floor covering is to be used.
  • Is perfectly suited to use in floating, bonded or unbonded construction and can easily incorporate electric or warm water underfloor heating systems.
  • It is pumped directly to where it is needed, removing much of the manual handling operations required to install other screeds.
  • It is finished using a lightweight dappling bar requiring no secondary compaction, thus removing most of the physical work needed to lay other screeds.
  • It is suitable for use on most substrate types.

How to prepare your floor for liquid screed

  • Remove any debris from the sub floor
  • A membrane of 1000 gauge or thicker should be laid immediately under the pipework (above the insulation board) as a slip layer, and to prevent leakage of the screed before setting.
  • Install an edging strip around the edges and corners of the wall and attach securely.
  • Any shuttering across doorways or steps should be fully sealed with expanding foam or mastic to prevent leakage after laying but before setting. Pipe ducts or holes through walls also need to be sealed before placement of the liquid screed.

How to prepare your floor for liquid screed with underfloor heating

  • Install underfloor heating pipes and ensure that they are clipped every 400mm and more around bends. Make sure that the system is full of water prior to the liquid screed being laid. This avoids the pipework floating to the surface of the screed.
  • If you are using an ‘eggbox’ type system, the membrane should be laid under the eggbox, and you should avoid using small off-cuts o eggbox to avoid any possibility of floating.
  • The minimum cover above underfloor heating pipes is 25mm.

Mistakes to avoid when preparing for liquid screed

  • Measuring the place incorrectly
  • Often sub-floor slope or unevenness may cause unexpected differences in the overall floor level and in the quantity of the screed required. It is the customer’s responsibility to measure each room/area appropriately.
  • You will need to consider critical features such as door openings, minimum thickness/cover and required differentials in floor height between rooms.
