Hi, I'm building a home with polished concrete throughout. I've noticed this post is a month old, so have you decided yet? I didnt' go with the usual aggregate as I felt it was too "busy". The concrete had charcoal dye added to the mix. I've seen pictures of it done with light colours as well and it looks good.

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

My thoughts are basically a summary of everyone elses . Step 1 -- sort the seepage . If you lay a concrete slab , any seepage will run around the concrete , potentially coming up at the 'join' between concrete and timber ( it will be difficult or impossible to completely seal that ) ; or it will flow somewhere else , maybe damageing other areas , or undermining foundations . Concrete to me is industrial ( cold ) ; timber is natural ( warm ) , and your timber looks to have some age and even yellowing ( which I like ) , so you are mixing the styles . Basically , it works in a shop ( down the concrete to the counter , or meander around the timber areas to see what you want ) , but not so much in a house IMO . Tiles ( personally , I'd like a gloss off-white with lots of grey and charcoal veins , but then that would be expensive and potentially slippery ) would be preferable imo . A terracota would look good and suit the period , just not as classy as an off-white . Charcoal or even black won't work quite the same , and to go anything else risks making it a 'novelty' -- blue or green or butter or purple may 'age' quickly , in fact I think probably 40 years out of date already haha ) .
