Sand & Cement vs Liquid screed - which is best? (70mm)

[Great_scot_selfbuild]

I'm getting quotes for both sand & cement and liquid screed floor layer over our UFH.

 

The depth was going to be 75mm, but it turns out my principal designer failed to take into account that the screed needs a layer of self-levelling compound on top before we lay our LVT, so I've been advised by multiple screed companies to allow for at least 5mm as I can always add SL Compound. Therefore, working back from the FFL and 5mm LVT, with 150mm PIR, we'll be needing 70mm of screed.

 

The initial costs I've had back aren't as different as I expected:

 

Area = 130sqm

 

If cost wasn't a deciding factor, what would you choose and why?

I like traditional sand cement screed.  75mm is quite thick for liquid screed.  If you go liquid, use Cemfloor as there is no laitance removal needed.  I have used Sigma Screed in the past and they were very good.

Use my mate for the dry screed and you can pretty much paint it green and play snooker on it.

 

You won’t need a full bed of SLC, your LVT installers will just use feathering compound wherever necessary (LINK) so less time and complexity and then it’s easier to manage trades.

 

You should only need to do a full layer of SLC if you’re putting LVT down over a concrete slab.
 

A good screeder will give you the result you want, save you time, and money.
