Answer: yes, provided that the old tiles are in good condition and planing the doors.
Laying new tiles on an existing tile is quite possible. It saves you from having to remove the old coating, it's faster and above all it costs less! The disadvantage of the method, however, is that you will have to adapt the doors of your home, you will certainly have to plan them by several millimeters. Another precaution of use, it is necessary that the "old" tiling is always in good condition, otherwise the new coating will not last long. In some cases, sanding old tiles will be necessary to facilitate adhesion of the adhesive. Be aware that there is a special thin-set mortar available for this type of situation, so that you do not have to use a primer to strengthen the adhesion of existing tiles.
