Common Issues to Avoid with Your Liquid Screed
Although relatively new onto the scene, liquid screed has fast become a popular choice for anyone laying a new floor or installing underfloor heating systems in their home or business. It brings a number of benefits, from fast installation to quick drying times and, of course, a wonderfully smooth and even finish invaluable for those laying subsequent floor layers — such as carpet, tiling, wood or vinyl — on top. What’s more, it provides a highly efficient insulative layer for the pipes used in water underfloor heating.
With so many benefits, it can be surprising when things go wrong with liquid screeding. If they have been properly installed by experienced liquid screed contractors, then it is very unlikely that you will ever experience any issues with your screed flooring, but cracks and delamination can happen if proper care is not given to your screed’s installation.

Laitance is a weak, friable layer that forms during the screed’s drying process, and its removal is a vital step that must be taken before work continues on your floor. The concrete screed floor beneath it is highly durable, but any laitance that is not properly removed will bear the brunt of heavy foot traffic, furniture and machinery instead. Eventually, this can lead to cracking, which is a time-consuming and costly issue to remedy.
Laitance removal will be scheduled and carried out by your floor screeding contractors, prior to any further work being done on your floors.
If the liquid screed mixture has not been properly combined prior to pouring, then ‘pockets’ of unmixed components will form within the floor and prevent it from forming a strong, durable base for furniture and foot traffic. In extreme cases, this can lead to ‘pits’ forming in sections that bear the most weight.
If your concrete screed flooring is not dry when floor coverings are laid, then the moisture will stop the floors from forming a proper bond with your tiles, floorboards or vinyl.
The drying times for liquid screed vary depending on the type of screed you use, the environmental conditions and foot traffic in the room, and how thickly the screeding was poured. A moisture test should always be carried about by your floor screeding contractors before you lay any subsequent layers of flooring, to ensure that the liquid screed has dried sufficiently.
