On a floor at the bottom of a small hole, a tile skipped, a smear with a hard tool, a chair that keeps stofinare on the same point, you can quickly turn into a chasm which remedy at a later time becomes difficult. For this you need to take action as soon as possible before the expansion of the hole becomes a necessity.

First you need to stem the spread of the rift, riempinedo gaps with the classic material obstruction that is the stucco with oil, the same that is used by hundreds of years in the maintenance of classic Venetian floors.


With plaster from tailors and linseed oil prepares the grout.

Gypsum, opportunely colored with lands to achieve a color pertaining to the floor to be repaired, is added to the linseed oil and mixed together until dough is pliable, but not liquid, which is spread with the spatula to cover the holes . Immediately after you dusted with another plaster grouting performed and rubs it so that is absorbed most of the oil and therefore do not form hollows.

Allowed to stand for a couple of days, you take away the excess with abrasive material (pumice stone or similar), then, when dry, sprinkle of raw linseed oil for the final outlet of the dough.

When grouting should not be more than sufficient, that is to say when the hole has become too large, or when the grouting continues to fall because the problem is not on the floor surface, it is necessary to intervene with the patchwork looking however, to change only the areas strictly necessary.

The procedure to follow is obviously the same as the type of floor to be repair, that is to say that the patch will be at the bottom on a floor in lime and cement on a concrete floor. Some might say that qualto reported now is a matter of course, but also in recent times to shorten the time of execution and believing that the new material could be more lasting, the patches were performed on concrete floors made of lime editing flexibility floor and running of racconci bad for color and quality, often without covering the cracks of the boards, referring to the fact the problem a few years because the cause of the damage was not repaired.
