A screed will typically consist of cement, sharp sand and water all being mixed together to make one solution. It is used on the top of a subfloor to give an even base in which you can lay whatever floor necessary. Screed can also be poured over and around underfloor heating pipes.
There are two different types of screed you should know about. This is a traditional screed and a liquid screed.
Traditional screed is a process that can’t be rushed as drying takes roughly takes five days to dry before it can first be walked on. Traditional Screed also has a 120-square metre limit of how much can be laid per day.
With this type of screed, if your floor is particularly large, you may have to insert joints to separate each area from the others. The thinnest layer of screed is 40mm where as it can also be laid as thick as 100mm, depending on what’s underneath.
Liquid Screed has a faster set time, meaning you are able to walk on the floor with 24-48 hours of it being laid. With our liquid screed, you can also look at laying up to 2,000 square metres per day, this is a huge difference from traditional screed. This will therefore suit large properties.
With this type of screed, you can force the drying rate. If you are behind on a project, thi is a useful method to get back on tracks. As well as this, in winter or in cold weather, you can force-dry the screed, helping you beat the dampness.
With a traditional screed, the ergonomics of scale are such that the larger the floor, the more expensive your screed becomes. Whereas, from 40m², liquid flowing screeds are lower in cost.
