Using PVA (Polyvinyl Acetate) glue before painting is not recommended because PVA can create a seal over the wall, preventing the paint from adhering properly. This can lead to peeling or flaking paint over time. For a better foundation, consider using a dedicated primer designed for painting. Primers are formulated to provide a suitable surface for paint, ensuring it sticks well and lasts longer.
