To avoid having to replace them too quickly, it is important to maintain your woodwork, especially if they are wood. In fact, the wood suffers more than the others the outrages of time ...
Before repainting, you will need to prepare the surfaces. There are products for easy stripping (Decapex, Syntilor, V33).
For effective protection, use a treatment against mosses, fungi and xylophagous insects.
Then, apply a liquid or gel glaze: it will prevent water from entering the wood, without smothering it, while protecting it from UV (Bondex, Syntilor, V33, Xyladecor). Their behavior over time is guaranteed from 3 to more than 10 years, and it is useless to strip the layers of years past. PVC windows are also entitled to a little summer makeover! For this, an underlayer will serve as a hook before painting. The same goes for non-ferrous metals such as aluminum (Bondex, Julien, Tollens, V33, etc.).
