Rainy and quite chilly this morning. Nothing near freezing, but quite bracing first thing. It’s supposed to clear later in the afternoon.
Here is a little technique that I have developed for repairing loose plaster. Sometimes in areas around a crack you can feel the plaster move when you press on it. This usually means that the keys have broken away on the primary layer of plaster and there is nothing holding the plaster to the lath any more. This example that I encountered in my renovation of room 8 shows an area where the top layer of plaster has broken away; and right beside it is an area that has broken away right to the lath. I use a 1 ½” stainless washer and a drywall screen and screw into the lath underneath. This should pull the plaster snug up to the lath and hold it firmly in place.
The hole can then be filled in with plaster. If the whole is large enough, obviously you would want to cut out all the plaster and replace it with a piece of drywall, but this area is only about 4 x 4”. After getting some plaster into the hole, I add another washer and screw in the area that had exposed lath. I put this through a piece of mesh tape. You can see it in the last photo if you look carefully. This is just to give something to hold the plaster to the lath, to give it a bit of strength so that it is no longer bouncing against the wall.
The frustrating thing about holes like this is that they take time to fill. You have to add the plaster bit by bit and give it a change to dry before you go on to the next layer. It takes a couple of days to get it completed. But the process seems to work well. I have used it in a number of places in the house and so far it is working extremely well.
Nothing in the garden for the last couple of days because my attention has been on room 8 and getting that done as quickly as possible. Fernando is under the weather again and has been in bed for the last 3 days which doesn’t help matters at all. He is painting the exterior door and I don’t want to hang it until he is done. Not that I am ready to hang it at this point, but I hope he’s up and around soon so that he can get on with it. How’s that for a sympathetic partner!
