Advice on bay window

[Aurelio]

Hi,

We have recently been having some work carried out to the front of our property including removal of pebbledash, repointing in lime mortar and repainting of the bay window. I am also considering having a lead covering installed on the exterior.

We have damp patches above the bay window on the interior and this happened before all the works commenced. Anyway, my question is how do I repair/decorate this area above the bay on the ground floor?

Should I use a lime putty filler for the cracks? Any advice. Thanks



Thanks in advance

If it’s a lime plaster then that’s what I would use for the repair. I would start by removing any loose flakey material.

To fill the cracks first establish more surface area for better adhesion. You can do this with a knife. Run it along the edge of the crack at an angle. This will open the crack further. Brush away any dust. Then spray the surface with water to reduce suction and prevent the new plaster drying too quickly. With the surface damp (not wet) fill in the crack and remove any lime residue from the surrounding area with a rag or brush. Then you can lightly smooth it out with a damp sponge.

You may want to lightly mist it to slow down the drying process. The once dry you can paint again.
