Each owner at least once in his practice faced such a situation when it is necessary to screw a screw into an old hole. As a rule, the situation at this point is already such that the hole can not cope with the reliable retention of the hardware and it starts to "walk" in the groove so that there is no sense from it. Some owners in such a situation try to put matches, but this usually does not help. What to do?
As practice shows, every person at least once encounters a situation when he needs to fix a hole for a screw. After all, as a rule, it happens that it is impossible to tighten the hardware next to it, and the old hole has already collapsed and deteriorated so much that it is simply not capable of holding the screw at all. At the same time, almost everyone knows that in this case it is necessary to "put something" under the structural element twisting into a tree. But, as practice shows, most people solve this problem according to the principle "I hear the ringing, but I don't know where it is."
In this case, of course, we are talking about simply placing a pair of matches or just wood chips in the broken screw hole. However, when most owners do this, they very quickly face an unpleasant surprise associated with the technology of their unpretentious restoration. The screw, even with matches, still does not hold in the hole, or the structure holds, but very quickly falls apart again. The worst of all is when you need to fix a loop in this way.

Many people overlook the fact that it is not enough to use only matches or wood chips for an effective restoration. Simply placing it under the screw will be useless if you do not use glue in the process. PVA copes with the task best of all. Before inserting the pieces of wood into the hole, it is necessary to pour the adhesive substance into it. It is also applied to the pieces of wood themselves. Then the glue should be allowed to dry for a while before starting to screw in the screw.

It would be even better to carry out a major restoration. To do this, you need to make a "gruel" from PVA glue, chips and sawdust. A well-mixed and mashed substance is pushed tightly and tamped into the old hole. Then you should wait a few hours and only when the composition has completely hardened - screw in the screw.
