Part 1, my family of 3 person with story cut short, - did flakes coating in 2009 from contractor met during roadshows that specialize in such flakes coatings, for both toilets, kitchen and service balcony, using Imported flakes - main toilet only use for bathing and weekly changing of water in pail for house mopping - discoloring appears more vividly over the shower standing area - many cracks appear in early 2013, warranty is over - water starts to sip through the cracks and under the flake coats, causing many hollow gaps between floor tiles and flake coats leading to peeling off - place non slip mat over the crack areas - finally one big piece came off during weekly toilet cleaning - service balcony, kitchen toilet and master toilet that is use less and has much less contact with water, still ok so far judge the condition on how i maintain the toilet for yourself
