Description : Hello, I need advice. I've never done it before, so I'd rather find out more so I don't let it go. In the corner of the room, plaster spilled down to the brick. There is a hole about 20x10 cm. Part ... how to do it correctly, so that I don't have to deal with it again in half a year. Thanks a lot
Last Answer : It can be assumed that this is an older plaster, made in the classic way. Remove any loose, bulging or otherwise damaged plaster. First put a spray, a little cement and a little sand ... recommend soaking the entire walls properly and scraping everything that allows it with a flexible spatula.
