Answer: yes, with tubes of enamel or white and tinted cement and varnish.
Whatever the width and depth of the impact, it is always possible to make it disappear. If your tiles are dull, get enamel tubes (which you can find in any DIY store). These allow to seal all the impacts and splinters on tiles. They are generally sold accompanied by a dye, you choose the right shade! Before filling the impact with the resin, the hole must be thoroughly cleaned. Once the shine has been filled with resin, smooth everything well. If you observe irregularities on the tiles at the point of impact, it is still possible to sand all after drying, but be aware that sanding will tend to whiten the surface. It is therefore not advisable to sand the surface if your tiles are not light in color. If your tiling is not matt, use a little white and tinted cement, then put a small layer of varnish on the repair. You too, send us your DIY question.
