Pointing, Mortars and Renders
Where it is desirable to keep the appearance of the pointing, mortar and rendered finishes as original we can have a sample analysed by an analytical chemist. The existing material is broken down into its constituent parts which can sometimes be as many as eight and are made up from various coloured local aggregates, sands and limes. Once analysed, the pointing, mortar or render can be reconstructed to produce an exact colour and texture match.
Masonry surfaces can be cleaned by various methods such as chemical cleaning, sand blasting or water pressure. These cleaning methods will take out weak and defective
pointing so re-pointing of some areas may be necessary.
