Have you heard of quartz carpet? It is a composite of quartz aggregate and resin, uv resistant no fade, soft underfoot, seamless indoors or outdoor use and can be installed over existing concrete floor, ply etc so evening a miss matched floor is easy. Mid century have some stunning leftovers like large elongated space, timber detailing and panelling and innovative material application for their time. When we restore them today often in respect to them we more often upgrade these innovAtions while still feeling at home. Remember cork floors, they felt great, insulated well and laid easily, but look outdated now, Quartz carpet has that same feel, but much sexier! evolution surfaces website can help. Their polished concrete veneer is also interesting. Good luck. ML Design

hi yes batches are different from batch to batch, but the finishers, toner, and self levellers, grout, are all different and have differing impact of the finish. Two of my Grandsons work in the concrete polishing industry (have for years)and come across this problem every other day. They are so very used to fixing up concrete pourers blues. I do know of some extreme difficulties (some over forty years old under carpet that have had the same problem) that have given my boys a hard time. However, at the end of it, using the right gear, you can literally see your face in the reflection plus the reflected image via the window.

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
