Town Hall prior to stone restoration 

This stone building, officially opened in 1900, was showing signs of damage due to weathering and dirt. Restoration of the natural stone on front and side elevations of the Town Hall was necessary.
Restoring damaged natural stone requires appropriate materials and methods in order to retain and protect stone and to reproduce its original appearance.
Natural stone restoration encompasses a range of different measures and processes which may have a preservative, restorative and/or preventive action.
•Stone consolidation
•Stone reinstatement
•Stone replacement
•Stone cleaning
•Water repellent finish
•Coatings
Stone consolidation is a restorative stone preservation measure. The aim of successful stone consolidation is to recreate the original strength of the material.

Recommendations were made for using the KEIM Restauro range of products for the cleaning, consolidation, repair and preservation of the natural stone. Due to the specialised nature of these products, and the highly sensitive areas of their application, advice was sought from Keim Mineral Paints.
