Flooring refurbishments


I asked my twitter contacts whether it was normal to screed over existing ceramic tiles when refurbishing flooring. The case in question is the atrium of my office building, which is having new vinyl sheet installed at the moment.

In my recent rant, I was baffled as to why seemingly perfectly good ceramic tiles were being covered over. There could be a variety of reasons, but Sam from The Rubber Flooring Company gave me some useful feedback.

The general advice is, where possible, to get back to the original substrate and apply a self-leveling smoothing compound. However, if budget or site won’t allow this, and the ceramic is sound, then they can be primed and screeded over, albeit with more risk of system failure.

Our building is in use during weekday working hours, so the site conditions are tricky, but judging by the move to a hard-wearing, easy-maintenance floor covering, budget may also be a primary consideration. But in the ‘age of austerity’ why the need to refurbish the floorcovering in the first place?

You can almost see the outline of the existing tiles in the picture above.
