    Troubleshooting Lime Mortar Leaching

    Lime Mortar Leaching has two possible causes: Exposure of pointing to rain prior to carbonation can cause lime to leach out of the pointing. It is important therefore that all mortars are protected from the elements until they have a chance to carbonate. If fat lime is used for building works it can take years for the lime in the centre of the ...
