Hi i have hired a tradesmen to screed a floor.
Crumbly floor screed.
The screeders 20 yrs experience worked really hard but said it was the worst screed they had ever seen.
The tradesmen completed the work but the surface is left crumbly and edges corners came lose and have now separated from the rest of the floor.
After a 10 days it is also cracking by the doorway.
Laundry has a waste in the centre of the floor.
And the entire floor is just as weak and crumbly as that point if not more some parts i can literally break away with my fingers.
So floor screed is.
We pulled up some lino floor which was backed with sheets of mdf.
My problem is now 4 weeks on the floor is very dry crumbely.
We are currently renovating our kitchen in a 1930s flat.
It was delivered quite dry and by the time we had finished seemed even worse but it trowelled up o k.

As i have removed the floor tiles in the laundry the screed below has come up in places and is pretty crumbly in others so i have removed the lot and am just back to the bare slab.
A rotary hammer drill would be overkill if the screed is crumbly a lump hammer and a cold chisel sound like they would easily do the job.
Mix ratio of sand and cement screed for floor varies based on the intended use of the screed.
There is an aluminium angle in the doorway and a metal.
The screed is incredibly crumbly and looks like.
Floor screed is composed of cementitious materials and sand blended based on a suitable mix design and applied to provide a leveled surface for the floor finish which is introduced to the surface of the floor screed.
When we started to pull up the mdf we noticed some kind of underlay screed that had been painted green but with a red core.
Instead of looking smooth shiney it was rough powery however much they trowelled it.
