Note: When using these washers to re-attach loose plaster or mortars, fasten the wider area back first with larger batons before adding the washers, when you have enough washers evenly in place you can remove the batons. We would also recommend you drill some holes through the plaster or mortar afterwards and secure it permanently with glue or filler foam.
