Today, if there is a need to replace the window, then more and more people turn their attention to the PVC windows. This is no accident. After all, plastic windows are quite simple in maintenance and very functional. But, unfortunately, nothing eternal happens. Over time, even plastic windows wear out and require repair work.
Any window has several main functions. It allows you to penetrate the daylight into the room and at the same time protects the dwelling from the cold. If it brings out from the window, then its sealing was disturbed. The problem must be solved as soon as possible. This is done using special building mixtures. The joints between the walls and the box of the plastic window can be filled with polyurethane foam. Even the owner of the house will be able to cope with this work. Because stainless steel railing, for example, is much more difficult to process.
A more difficult task is to process joints after the foam dries. After all, the window should have an aesthetic look. In this case, the help of specialists may be needed. The fact is that polyurethane foam is very sensitive to various atmospheric phenomena. The sun is especially destructive. Under its influence, foam can dry and crumble. Therefore, the joints must be protected. For this, special plaster is used. Work should be done a few days after applying foam.
You can also protect the foam from destruction using painting. In this case, the foam after drying is cut, and the paint is applied to several layers.
From moisture exposure, the joints will help protect silicone sealant. It should be applied to plaster and painting.
