I am trying to find a suitable filler for an interior cob wall that my builder who is not experienced with lime can use.
The cob wall area is 3m by 1m and depth of about 30mm. What suitable breathable lime filler do you recommend and how much do I need?
I would like to skim finish the area with a final coat of lime breathaplasta.
Thank you for your enquiry. Our Cornerstone Insulating Render would be very suitable here – you will need around 7 bags for the area and depth that you have mentioned. Once completed you could use a very thin skim of Breathaplasta or we would recommend using our CLM66 lime putty plaster as your finish coat.
