Internal lime mortar

1.21K viewsBuilding Restoration

My partner has a late 19th century mid terrace, 2 bedroom house in Illogan, Redruth.

The front (south-facing) wall is constructed of good quality granite and stone, cement pointed and  ”sealed”approx 5 years ago (before she moved there). Internally, damp has blown the plaster off, to approx chest height in the 1st floor bedrooms(dry above that), extending all the way down to the ground . We have removed it all,(pictures to follow hopefully) along with cement render used to patch areas in the past, to allow the wall to dry.

After reading much of your pages,I’m still unsure which pointing mortar to use between the stonework? We are still undecided on the eventual finish, which could be from your breathable plaster to a breathable plaster board…

As it is a small area, ease of use without mixing would be best for us to DIY.

Thanks in advance.

Thank you for getting in touch.  There are a few ways to deal with your issues.  You could use our CLM28 putty mortar which is a wet ready mixed product or our CLD30 Drymix product which you add water to. – either are appropriate for internal use.
We would also recommend the use of the Cornerstone Tanking Render around the window reveals to make these more water tight and then then either CLD30 or CLM28 to build out other areas, followed by CLM66 as a plaster finish.
If you wanted to give us a call on 01208 79779 this may be easier and we can run through it all with you.
