Cross a wall
It is sometimes necessary to cross a wall, a partition or even a floor. As PVC carries water at various temperatures, it sees its diameter change not insignificantly. It should not be bothered by masonry.
For this purpose there are elastic lining sleeves. It is possible, if necessary, to inject polyurethane foam which ensures flexibility and insulation of the duct. In concrete, it is advisable to drown the pipe in sand before pouring the mortar.
Traditional painting is not suitable for PVC. There are special paints for PVC conduits but they are usually white. More effectively,
there are underlayments for PVC that will allow you to then apply the paint of your choice. This makes it possible to match the ducts to the color of the walls.
