The purpose of this guide is to assist those who wish to restore facades constructed of or finished with dimension stone. It is an aid to owners, building managers, architects, engineers, contractors and others involved with restoring dimension stone.
This guide is not meant to supersede manufacturers'' directions and recommendations for the use of their specific products, or written directions from the architect or building owner. When manufacturers'' directions are in conflict with this guide, follow their recommendations or consult with their technical staff for further direction.
Prior to undertaking a full-scale repair or cleaning procedure, the methods under consideration for repair, patching or cleaning should be tested on an area not easily visible or on sample stones. The test will assist in judging the effectiveness of the chosen method and permit assessment of potential damage to the building stone. Completely evaluate the success of the sample repairs before undertaking the full-scale cleaning or repair procedure.
