If underfloor heating is installed insitu onto steel reo correctly and the concrete poured to the correct cover (thickness) over, there shouldn't be reason to see any cracking as a result from in-slab heating. If unsure, make sure to ask for references and see any previous jobs completed.

we have decided to go with concrete floors in our new build. the foundations have just been done, and the team came through and power floated the floor. It rained the next day, which showed us the full effect of what the floor will look like (the builder said its good for it to rain too as means less likely to crack) and we LOVE it! so much so that i rang the builder and asked him to be careful on the hallway floor too as we want to continue the concrete finish up there as well. We arnt going for a ground floor as i find it a bit too busy and we are wanting a more relaxed industrial look. This is the photo i supplied the builder and it looks pretty much the same. The finish is achieved as soon as concrete foundation is poured. they "buff" the concrete, which "burns" the top, giving it quite a organic look. once this is done, the floor needs to be protected from chips etc while they build, then all that needs to be done is sealing once the build is finished. it came in alot cheaper than tile, or wood, but more expensive than carpet. our house is north facing with a lot of glass on that wall. the architect told us that the thermal mass from the flooring will be awesome! keep us updated on what you choose. :)

Hi Josette Polyurethane based sealers often turn yellow when they are exposed to UV. The same thing can happen with oil based white paints where they are NOT exposed to UV and the tannins turn them yellow. I would speak with the installer and find out what product was specifically used and then make enquiries with the supplier of that product. Cheers

@pottsy99 we really loved the house when we first bought it, especially the kitchen for its unique character. . After so many years living in the house, it started to feel quite dark and dated we wanted to change the home without moving. We are happy with the result and update As this was the last room in the house to do. Everyone has the own sense of style and what they like and this is what we like. The only thing that matters is what we like as we are living in it. Thanks for your thoughts.
