SIGNIFICANCE AND USE
4.1 Repointing masonry improves weather resistance, reduces water penetration, maintains structural and visual integrity, and prolongs the life of the building by allowing a mortar joint to shed water and avoid the accumulation and penetration of rainwater between mortar and masonry units.  
4.2 This guide provides for the selection of the most effective methods appropriate for repointing masonry based upon the following parameters:  
4.2.1 Determination of joints to be repointed.  
4.2.2 Evaluation of in-situ masonry.  
4.2.3 Evaluation of techniques for removal of mortar.  
4.2.4 Determination of appropriate repointing mortar.  
4.2.5 Selection of repointing mortar.  
4.2.6 Establishing the method of execution of the work.  
4.2.7 Visual inspection of the work.
SCOPE
1.1 This guide applies only to existing historic masonry construction. For purposes of this guide historic masonry is intended to refer to buildings that have significant historic, architectural, cultural or social meaning and are constructed of masonry materials. Similar techniques and evaluation should be employed for non-historic masonry, but are not addressed in this guide.  
1.2 This guide outlines procedures for repointing historic masonry and is intended to provide guidelines for the user to establish project-specific requirements for repointing of historic masonry.  
1.3 This guide only pertains to masonry units: brick, terra cotta, stone, cast stone, and concrete brick laid in mortar, and may or may not be appropriate for other masonry units.  
1.4 This guide addresses repointing (tuckpointing) as defined in 3.1.3.  
1.5 When considering repointing, especially on masonry of artistic, architectural, cultural, or historical significance, guidance from a specialist experienced in historic masonry and repointing should be sought.  
1.6 This guide does not address pointing styles or profiles used on masonry or the methods of producing them.  
1.7 Additional repairs that may impact the structural integrity of the masonry may necessitate that a structural stability analysis be completed prior to the execution of any work.  
1.8 Following this guide may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory requirements prior to use.

SIGNIFICANCE AND USE
4.1 Cleaning of masonry, concrete, and stucco surfaces is undertaken for a variety of reasons including aesthetic improvement, removal of contaminants, maintenance, and surface preparation. This guide provides for selecting, testing, and evaluating cleaning techniques for removal of soiling and staining.  
4.2 Cleaning systems may adversely affect both building materials being cleaned as well as other materials, mechanical, electrical, and other building systems, and building exterior, interior, and site features.  
4.3 In some situations, it may be prudent to spot clean or to not clean.  
4.4 It should be noted that, in some cases, cleaning may be inconsistent with the goals of historic preservation.
SCOPE
1.1 This guide covers procedures for the selection and assessment of cleaning techniques for removing soiling and staining from masonry, concrete, and stucco surfaces. Removal of paints, coatings, and graffiti may require measures beyond the scope of this guide. New construction is excluded from the scope of this guide.  
1.2 This guide does not purport to address the causes of soiling or staining or to propose remedies for recurring soiling or staining.  
1.3 Where work on surfaces of artistic, architectural, cultural, or historic significance is being considered, guidance from specialists should be sought.  
1.4 This guide does not purport to address removal and replacement of prior repairs, repair of damaged surfaces, or other irregularities that contribute to the uneven or discolored appearance of masonry, concrete, and stucco surfaces.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
4.1 Energy conservation is being addressed more often on existing and historically significant buildings constructed with solid exterior mass masonry walls. Without proper evaluation, changes to the thermal and moisture properties of the exterior walls could have serious negative impacts on the existing masonry, new or existing wall components, and building operations.  
4.2 A thorough understanding of the original construction and subsequent alterations, condition of materials, properties, initial moisture content, water and air leakage potential, and building operations are necessary before undertaking the addition of interior insulation, air barrier, vapor retarder, or other changes to thermal or vapor resistance of the wall.  
4.3 Degradation of the existing masonry along with moisture related problematic conditions and indoor air quality issues could develop if alterations are undertaken in an improper manner to the exterior wall assembly.
SCOPE
1.1 This guide addresses the evaluation of existing mass masonry walls for the potential addition of interior insulation and continuous air barrier or vapor retarder or other changes to the thermal and moisture management properties of the wall.  
1.2 This guide describes methods for evaluating moisture accumulation related problems specific to mass masonry walls. This guide does not apply to walls that include provisions to manage bulk water through internal drainage, flashings, or other measures other than the moisture storage capacity of the wall.  
1.3 This guide describes analysis, design, and specification of materials with the required thermal, air, and vapor resistance to improve the energy performance of an existing mass masonry wall, but that would not create problematic conditions to the masonry units or within the masonry wall or interior of the building.  
1.4 This guide applies to walls of masonry construction meeting the requirements of a “mass masonry wall” as defined herein. This guide does not apply to masonry walls that, by design, are intended to manage water as a barrier wall system or drainage wall system.

SIGNIFICANCE AND USE
This guide provides information on methods that can assist the design and conservation professional in the selection and use of consolidants for stone.
Use of a consolidant should be considered only after developing a thorough understanding of all factors contributing to the deterioration of the stone. Such an understanding is best reached through a comprehensive survey of existing conditions, environment, and a definition of stone performance requirements, followed by laboratory analysis of the stone and its deterioration products. With this information it should be possible to identify the decay mechanisms and to develop a conservation plan for the stone. However, careful preliminary investigation may indicate that consolidation is an inappropriate treatment.
Decay Mechanisms—A discussion of decay mechanisms is beyond the scope of this document; however, an understanding of decay mechanisms is critical to the evaluation and selection of appropriate treatment methods for stone including chemical consolidation. (See Bibliography for references.)
Stone consolidation should only be done as part of an overall conservation plan. Consolidating stone without resolving underlying problems contributing to its deterioration (such as rising damp or improper drainage) can cause the consolidation treatment to fail completely or to accelerate the rate of deterioration of the stone. The condition of the stone should be documented before and after treatment.
Past experience has shown that application of some consolidants may contribute to deterioration or create unanticipated problems. In some cases, it may not be appropriate to use a stone consolidant at all. Consolidation should be considered only after unsuccessful attempts to remove or modify degradation sources have been carried out.
Consideration should be given to the fact that consolidation of porous stone is an irreversible process. Consolidants that allow future retreatment should be selected if possible. For e...
