Hi Indira Think I will have to change all the materials since I don't have spare tiles from the renov then. If I just touch up the defects area means the flooring will be of different colours... =( is less than 5 years.. so sad. Can't recall the exact area space, my tiles is 60x60, think it should be 16.2sq metres. Bamboo flooring is new? Does it come in different colours? The colour theme of my hse is white and dark brown. We are thinking of just changing it to the normal white tiles will do, don't want to spend too much on this... Thanks much!
