Itarc, so sorry to hear that you do not like the wall... what is wrong with it besides the cracking? Truth be said, I think that there must be some allowance for hairline crack because that is a common scene although I have seen some cement screeding that is perfect and has been that way for years. If you want to see what you can do about it, you can go the the My Humble House (under the Tung Lok Group) at Esplanade. They have what you are trying to achieve I believe with an additional plus.. Look carefully on the wall and you can see inbuilt lights. I recommend that you take a look first, ask the restaurant who they got to do the wall and ask them for advice on how to do it properly should you want to do it again. If not, at least they might be able to rectify your faults. Cheers Gate
