polished (honed) concrete problem
We are currently building our dream house and have encountered a problem with our honed concrete floor. Our builder and concrete polisher don’t know why it happened and have no solution.
Concrete floor was honed and looked fantastic, it was then covered for some time to protect it while other building works were going on. Few weeks ago it was uncovered, again everything looked good. Builder then got the cleaners to clean the house and as soon as they left we noticed that dark streaks/patches have appeared. We first thought that cleaners must have used cleaning product not suitable for honed concrete but they assured us they only used water.
Everyone we contacted so far has no idea why it happened or how to fix it.
I should add that we have hydronic heating installed. Thinking that it might be moisture related we have turned the heating on to dry it out but we can’t see any difference. We do have one room that is perfect, has not shown any dark streaks and cannot work out why??
If anyone has any idea of why this happened or if there is a way to fix it, I would be grateful for any help.

Polished concrete or tiles???
Comments (3)Hi nancynik, While polished concrete is right on trend now, amongst other things, you should consider; 1. Your styling aesthetic - whether concrete suits how you plan to furnish and decorate. 2. Your future in the home - is it a long term home and if so will polished concrete suit your taste in the future? 3. The style of your new home and the rest of the finishes both inside and outside your home. 4. Where you live and your lifestyle. There's many more points that need to be considered prior to making a decision this big. You might consider getting advice for the entire finishes selections. The right person will ask the right questions to provide you with a cohesive scheme for your new home. Hope this helps. Enjoy your new home!...See MoreWho can do outdoor Honed concrete driveways in Sydney? Help!

Comments (14)I remember hearing of the product in the original question, name added in a subsequent post. My immediate thought was that preparation of the surface is crucial and even more so for this product as it is very thin. This is what I found on the manufactiurer's website. "As far as old ceramic, cotto, stone, marble or PVC floors are concerned, make sure they are sound and firmly fixed. The existing floor must be dry, stable, sound, perfectly flat and clean, which means that there must be no brittle fragments compromising adhesion of Kerlite Plus. Flatness checking should be performed using a screed with a length of at least 2 metres. Place the screed on the old floor in all directions and, if necessary, compensate for any differences in level." https://www.cottodeste.com/solutions/faq?_ga=2.261653453.1349840659.1675227047-1392414663.1675227047...See Morestrata issues for polished concrete in old apartments
Comments (1)Hi Marilyn, Hard floors are outlawed by a lot of Strata buildings. You will have to check with your own building Strata manager. If allowed and you do remove the carpet, any noise complaints from neighbors will be considered and you will possibly have to re carpet. All the best,...See MoreKate

If not then it might be good to have the slab depth scanned, though there's not much you will be able to do now. You are left with a permanent visual reminder of the shrinkage cracks and where the mesh is within the concrete.
