Hello,
What should I use to fill the hole?
Old house in northern Skåne on a stone foundation with an uneven keso-like type of plastered (?) & likely limewashed facade. The exterior walls are about >30 cm thick & consist of regular stone and some type of mortar/plaster that is white & sandy and kind of erodes when, for example, drilling etc. It is more mortar than stone...
I have now had electricians there who have drilled right through the wall & pulled a cable. Therefore, it is like a deep crater. Some say c-mortar, others say I should use b-mortar, and someone says silicone. What is the right one?
Best regards,
Confused Jessica

One should use the same type of plaster that is already on the wall, and judging by your description, it seems to be some form of lime mortar. I would use a lime mortar instead. For example, one of the mortars on this page: http://www.weber.se/fasad-puts-och-...uts-utan-isolering/weber-kalkbrukssystem.html. There are more manufacturers of lime mortar.
Thanks! I think over time all types of mortar/cement have been used for repairs. This time, however, I'm thinking of trying to do it myself (since the facade is completely uneven anyway) and because I'm now going to insert the mortar several decimeters deep, it feels important to choose the right material. I'll pass by a company that sells lime mortar tomorrow.
