The main thing is that a small crack does not lead to serious damage, otherwise you will have to spend more forces, time and money. Here I will tell you how to close the crack in the wall with my own hands.
Why cracks appear
The causes of the occurrence are quite diverse. If you saw the cracks of no more than a millimeter in your home, then there are no reasons for panic. Experts call it a completely permissible phenomenon at which it is not necessary to take a construction store and acquire materials for repair.
The appearance can cause a change in the ground under the house itself plus the lack of carrying ability of the walls. Such a crack can be reappeted using a mirror. But here it is necessary to pay special attention to the material from which the building is completed. If the brick and concrete are one, then the crack in the wall of foam blocks is already a big danger to all construction. But the panel house is not too troublesome for repair.
Non-last role play swelling and shrinkage - behavior of material at moisture and different weather conditions. This also includes the purpose of using the building and the loads rendered on it.
Permanent vibrations, wind, reinforced traffic, high temperatures - also important factors that affect the appearance of cracks in one or another element of the house.
What is dangerous crack?
Danger appears if the reason for the appearance of the split is defects of construction after major repairs or restructuring. To make sure, apply a plaster label or control strip on a crack. Take a little specially prepared gypsum and apply for a cracked place somewhere on the width of the palm. If during three or four weeks the crack does not appear - not so scary.Article on the topic: Varnish for parquet: how to choose without odor, quick-drying coating, polyurethane parquet varnish, how many layers apply

They will help to keep track of both vertical and horizontal changes.
