Breathable screed finish for old victorian yorkstone flags?

Anonymous user 09/03/2024 - 3.28 PM

Hi all, I have purchased a victorian end-terrace built circa 1905. The kitchen still has the original yorkstone flags but I've had a restorer visit who has advised they are too far gone to restore. Rather than replace the entire floor, would it be possible to simply cover it in a breathable self-leveling screed that has a smooth finish on the top? Perhaps then finished with another breathable floor covering? I want to avoid creating any damp issues, but also avoid the cost and time to replace the entire floor, if possible. Not sure about the options. Any suggestions? Thanks

Are you a tradesperson and able to answer this question?

I can’t be absolutely sure but using a liquid membrane then a latex screed might work

The best solution would be to remove the flags, reduce the ground ,prepare and lay visqeen Damp proof membrane, insulate with kingspan type insulation 75mm thick and lay new 100 mm concrete floor.

Hi Robert, Self levelling compound is porous anyway, but that wont stop a damp issue. You don’t need breathable materials, you need to stop the damp from rising. You need to cover the floor with a liquid DPM then self levelling compound, you can then lay whatever floor covering you choose. You may still have an issue with damp up the walls if there is no damp proof course and/or you are below external ground level and have no cavity. There are ways of treating this also.

Under no account should you use cementatious products, these will have the affect of pushing any damp to the walls. I would excavate down to a depth of approximately 8 inches and lay Terraim down, then a 4inch layer of blown glass, another layer of Terraim and a 3 inch thick sand lime screed. Clay brick tiles could then be laid on the cured screed.
