Why crack the slopes. 3 reasons
The decoration is sometimes it happens that even the perfect slope at some point gives a crack. And the masters of the blame in this, though not always. Why is he still gives the cracks? Here are some real examples.
If the slope is decorated with putty or cement-sand plaster and painted with high quality, in normal circumstances it should not crack. And a year later, and after five years, his appearance does not deteriorate. But there are three main, independent of the cause of the masters, of which high-quality work can be spoiled.
1. shrinkage home
It is observed even in homes built decades ago. Subsidence of the foundation, or a multi-storey part of the house can not be stopped, so you have to put up with it and If cracks do local repair slopes, using, for example, strips of translucent glass fiber.
2. vibration
The problem is typical for homes located close to the roadway. Perhaps you've noticed that transport sometimes creates a resonance that the glass shaking. But the same thing happens with the wall, but unlike glass cracked walls.
3. supercooling
This reason accounted for very few people, so it may be impossible to explain what happened to the slope in the house is not subject to shrinkage and vibration. cracks are often observed on the window and door slopes of the windows, through which the room ventilation is performed in the cold season.
When you open the plastic window on ventilation (open the upper part of the leaf) the cold air cools only part of the slope, while the remaining part is warmer.
So because of the temperature difference in the slope of the voltage created and finishing burst. And no matter what plastered slope, a conventional mortar or mastic, a crack may occur. Most often it passes across the slope in the middle part of the height.
A little comforting that in the warm season temperature crack absolutely invisible. To such a problem does not appear, it is better not to air the room for a long time, especially in cold weather.
There are other reasons for the formation of cracks, which involved finishers. About them discuss in another article. Keep an eye out for new materials and subscribe to the channel, so as not to miss the useful material.
