had a water leak from the shower, ground floor bathroom and water got under laminate floor.
The Laminate has now removed, but floor screed/Self Leveling Compound is damaged and come away in places, the rest is well bonded to the solid concrete floor below. the screed is probably 2-4mm thick.
I have a dehumid & heater running to dry everything out, when it is all dried out, do I need to remove all the screed or SLC (whatever it is) or can you just put a thicker layer of SLC on top.
If I have to remove it, any idea’s other than a hammer and chisel?

To the best of my knowledge the screed is about 15 years old.
Once complete, the floor will be replaced with lino/vinyl flooring.

Hammer and chisel won’t take long, it’ll come off fairly easily. Don’t see any big problems with putting a new layer on top if you’ve satisfied yourself that what’s left is pretty solid.

a lump hammer on its own will remove SLC thats looking a bit suspect.

no issues with overlaying with SLC slightly thicker IF what its bonding to is solid.

If you have alot to do a wide blade chisel bit in an SDS that has a non rotating chisel function.

thanks
Will give it another go with a lump hammer and Chisel
Guess I’ve got a week or two of drying time to remove it
