Screed Floor

[chrisl25]

Our living room floor is a quarry floor with screed over the top, however where there is heavy traffic, the screed has broken down. Its almost like walking over egg shell.

I need a bit of advice on how to relay the screed and what to use etc.

Any help would be great.

Your screed is simply cement and sand in the ratio of 1:3. However, when you examine it you will find that there is a very thin hard crust on top and beneath that everything is soft and like sand without adhesion. This is because it was laid too dry, without sufficient water, and is the most common cause of the failure of screeds. Bonding screeds to quarry tiles also takes some knowledge and care, and you will find that there is no bond. It will be much more satisfactory for you to remove all of the existing screed and then buy some MDF boards of the same thickness so that you do not have to adjust skirtings, doors etc. Neatly cut and fit the MDF to your room using a few blobs of "No Nails" on the quarries to stop any tendency of the MDF to move. Then lay your carpet or vinyl on top and forget all about wretched defective screeds !!!

Thanks guys,

I took some of the carpet up at the weekend to check the rest out, it has not stuck to the floor, its just flexing over the top.

I'm thinking of laying a laminate floor over the top which should take some of the direct pressure off the screed, but the MDF idea I think is one worth looking into.

Thanks.
