In my conservation repair work, it is imperative that an understanding of the building or structure is gained before specifying and undertaking any works. For lime-based works this is particularly important.
The first stage, prior to starting any work is always a close inspection and survey of the existing masonry walls and their condition. This aims to identify and differentiate between any original mortars and later repairs. Any inappropriate mortars which are causing accelerated decay of the adjacent masonry should be removed and replaced with more appropriate materials.
Appropriate and representative mortar sampling and analysis can reveal the constituents of original mortars and assist me in developing compatible specifications which will closely match the colouring and texture of the original mortars.
