Polished marble floor may be the best choice of finishes but a lot can go wrong. It’s tideous with loads of areas need to control right from cutting and production, to selection, to handling and delivery, to installation and to polishing. Marble as a natural stone has characteristics which sometimes cannot be avoided during the selection. There are crystal lines that are deep and quite few are shallow. So even though we knew that the marble is solid during the selection, it would somehow come out as many pin holes after grinding. Some holes and fissures are too small that when epoxy is applied during polishing are covered but some are too big. So manual application of glue is necessary. Marble also easily reacts with oxide and other household chemicals so stains are always found after the installation. It cannot be avoided but could be removed using cleaning agents. You can use products from Primalas to remove the stains if you can afford but other economical brands can also be found in the market. Just decide wisely so won’t end up scratching your head. Another common defects are chipped edges and movement cracks. These are the defects which need high level of skill. Patching the chips and cracks might be as easy as it sounds but the difficult thing upfront is to match the colour of the filler and the parent material. Sometimes it looks alright during application of glue but when it dries you can notice the difference in colour tone. So you have to try and try until you get it right. If you have time constraints then you must get it right first time. That is the key for a good quality product. Be careful not to break the marble after installation. If broken, you need to remove and replace it with new marble. And replacing marble is not an easy task. You need to get the right colour tone in a group so it is not so obvious. The tricky part is when you need to match the light to dark colour distribution. Not many contractors can get it right but there are few who can do it but it comes with a big price.
