DEFINITIONS
<ol type="A"> Raw Adobe or Natural Adobe. Adobe, or sun-dried bricks are never kiln fired. Unbaked adobe bricks consist of sand, silt, clay, and water mixed together by hand, formed in wooden molds, and dried by the sun.</li> Stabilized Adobe. Stabilized adobe is common today, consisting of the same elements of raw adobe, but with the addition of stabilizers, i.e., cement, asphalt, and/or bituminous materials. Stabilized adobes differ from traditional raw adobes in appearance, permeability, and strength.</li> Adobe Mortar. Walls composed of raw adobe bricks are laid with mud mortar. The adobe mortar shall have the same components and characteristics as the material used as raw adobe bricks. Such mortar exhibits the same properties as the bricks: relatively weak and susceptible to the same rate of hygroscopic (moisture absorptive) swelling and shrinking, thermal expansion and contraction, and deterioration. Cement and lime mortars are incompatible with raw adobes.</li> </ol>

SUBMITTALS
<ol type="A"> The Contractor shall submit a detailed schedule to architect for approval of the work to be conducted, including an assessment of the problem areas, historic adobe and plaster analyses, and detailed procedures for adobe and plaster repairs.</li> The Contractor shall submit manufacturer’s product literature to architect for all proprietary products proposed for adobe and plaster repair. Product literature shall include specification data, Material Safety Data Sheets, and instructions for storage, handling, and use.</li> </ol>

MATERIALS PATCHING HISTORIC ADOBE
<ol type="A"> <li>Soil for adobe mud mortar: The Contractor shall provide soil to match closely the strength, component soil mixture, texture, and color of existing adobe in building walls. <ol> <li>The mix shall approximate the relative sand-silt-clay proportions of the existing adobe within a tolerance of plus or minus 10 percent.</li> <li>Contractor shall arrange for soil component hydrometer tests and compression tests of representative samples from the historic adobe brick types; coordinate removal of sample bricks from building with the Architect; and arrange for hydrometer and compression tests of new bricks to confirm compatibility.</li> <li>Dried bricks made from such soil shall have a compressive strength similar to that of adobe bricks in the existing building within a tolerance of plus or minus 100 psi.</li> <li>The color of the new bricks and mortar shall match that of the existing adobe brick colors. The Contractor shall match the historic adobe bricks, NOT brick that may result from poorly matched contemporary repairs.</li> </ol> </li> <li>Methods of material supply: Soil to match historic adobe may be a locally obtained material with no formal, readymade supply or suppliers. <ol> <li>Soil for adobe bricks and mortar may be tested or field matched from local soil samples; method for soil matching is to be determined by the Architect. When soil is field matched, test samples of possible soil matches are taken and placed in a glass jar (mason jar tested) with water to settle for 1 to 2 weeks. The settlement is compared with a similar test conducted on the historic brick, whereby a sample is taken, crushed, and placed in a glass jar with water to settle for 1 to 2 weeks. For commercially available materials, compare any available sieve analysis to that of historic material.</li> <li>Arrangement for the excavation and acquisition of soil and permission to access soil not on the Owner’s property must be obtained by the Contractor with the approval of the Architect. Any additional consultation required in order to acquire the appropriate type of sand is not covered under the terms of this specification and must be completed under IAW applicable laws (NAGPRA, ARPA, NHPA).</li> </ol> </li> <li>Water used in the fabrication of adobe bricks and mortar shall be clean and potable.</li> </ol>

PROTECTIVE COATINGS ON ADOBE
<ol type="A"> <li>Mud Plaster <ol> <li>Soil for adobe mud plaster should follow the material guidelines under 2.01 above and match the adobe mix used for mortar and bricks. Soil to match historic adobe may be locally obtained material with no formal, readymade supply or suppliers. Provide soil to match closely the strength, component soil mixture, texture, and color of existing adobe in building walls.</li> <li>Mix shall approximate the relative sand-silt-clay proportions of the existing adobe within a tolerance of plus or minus 10 percent.</li> <li>The color of the plaster shall match that of the existing adobe mud and brick colors. The Contractor shall match the historic adobe mud, NOT the adobe mortar or brick that may result from poorly matched contemporary repairs.</li> <li>Water used in the fabrication of mud plaster shall be clean and potable. B.	Whitewash</li> <li>The Contractor shall select a whitewash made from ground gypsum rock, water, and clay. Avoid the use of lime as this is not compatible with adobe and will not adhere to the bricks.</li> <li>The Contractor shall match the existing in color and texture.</li> <li>Water used shall be clean and potable.</li> </ol> </li> <li>Lime Plaster <ol> <li>Although widely used beginning in the nineteenth century for both exterior and interior coating, lime plaster is much harder and less flexible than traditional mud plaster, and subject to cracking.</li> <li>The Contractor shall test and match the existing plaster in color, texture, and composition.</li> <li>Lime should conform to ASTM C 207, Type S, Hydrated Lime for Masonry Purposes: 1,800 psi (2:1:9).</li> <li>Sand should match the existing stucco as closely as possible in color, texture and gradation, be free from impurities, and conform to ASTM C 144.</li> <li>Water used shall be clean and potable.</li> <li>Straw, hair, or fiber (if used) should be goat or cattle hair, or pure manila fiber of good quality, ½ to 2 inches in length, clean and free of dust, dirt, oil, grease, or other impurities.</li> <li>The Contractor shall use pigment that is compatible with lime.</li> </ol> </li> <li>Cement Stucco <ol> <li>Although not a traditional material for application over adobe, cement stucco came into use during the early twentieth century on revival styles of Southwest adobe architecture. Cement based stuccos are not compatible with adobe and are therefore, applied to wire lath and not directly to the surface of the adobe brick.</li> <li>The Contractor shall match the existing stucco in color and texture.</li> <li>Lime shall conform to ASTM C 207, Type S, Hydrated Lime for Masonry Purposes: 1,800 psi; OR</li> <li>Gypsum: It is important to note that gypsum-based stucco is NOT compatible with lime based stucco. The two should NOT be used in conjunction with each other.</li> <li>Sand shall match the existing stucco as closely as possible in color, texture and gradation, be free from impurities, and conform to ASTM C 144.</li> <li>Cement shall be white, nonstaining portland cement and conform to ASTM C 150, Type II.</li> <li>Water used shall be clean and potable.</li> <li>Straw, hair, or fiber (if used) shall be goat or cattle hair, or pure manila fiber of good quality, ½ to 2 inches in length, clean and free of dust, dirt, oil, grease, or other impurities.</li> <li>Pigment (if used) shall be compatible with the stucco mix and conform to ASTM C 979. <li>The Contractor shall use galvanized wire mesh, lath, and nails.</li> </ol> </li> <li>Other Coatings: When historic surfaces are coated with other mediums, the material shall be tested by the Contractor and matched in color, texture, and composition to the historic material. All testing results and product recommendations are to be reviewed by the Architect for approval. Other coatings may include but are not limited to: <ol> <li>Paints such as oil base, resin, or emulsion paints.</li> <li>Coatings of plant extracts.</li> </ol> </li> </ol>

GENERAL
<ol type="A"> <li>Assessment of Adobe Deterioration <ol> <li>Determine the nature and extent of the deterioration.</li> <li>Identify the source of the problem causing the deterioration. The source causing the deterioration is to be repaired prior to start of the work in this section.</li> <li>Develop rehabilitation and restoration plans for review by the Architect that are sensitive to the integrity of the historic adobe building. Submit a schedule of all work included in this section. Also refer to Section 04290.02, Repair Through Patching, Surface Coatings, and Structural Supports.</li> </ol> </li> <li>Rehabilitation and replacement of adobe building materials shall be done with the same types of materials used originally with the same construction techniques. Building materials should be traditional materials crafted by hand as outlined above. Do not substitute modern materials or add portland cement or lime to traditional mud bricks or mortar.</li> <li>The extent of the work covered in this section shall be reviewed by the Architect on-site prior to beginning operations. The Contractor shall submit a testing schedule and a schedule for adobe repairs, including the methods and materials to be used.</li> </ol>

ADOBE REPAIR PATCHING
<ol type="A"> <li>Brick Repair. When the surface of an individual adobe brick has partially disintegrated or has minor spalling with losses of up to ½ inch, it may be patched in place. <ol> <li>See Section 04290.01, Adobe Properties and In-Kind Replacement for adobe brick and wall replacement.</li> <li>Scrape out the deteriorated material to solid. The excavated void must have vertical walls and a horizontal top and bottom to provide solid support for the patch.</li> <li>Remove loose and deteriorated materials. The area shall be free from mortar or paint chips, dust, grease, or oil. Brush clean with natural bristle or nylon brushes (metal bristle brushes are NOT to be used).</li> <li>Lightly spray (do not soak) the area of the patch with water to facilitate a better bond.</li> <li>Apply the adobe mortar to the area, building up to the level of the brick.</li> <li>Allow the adobe patch and mortar to dry in place a minimum of seven (7) days before continuing with the next phase of wall repair. If wet or unusually humid weather is encountered, or if it is evident for any reason that installation is not sufficiently dry, extend drying time accordingly.</li> <li>After repairs have been completed and the surface has dried sufficiently, proceed to Adobe Coatings (below) and finish to match the existing surface.</li> </ol> </li> <li>Repair of Cracks in Adobe: A method similar to repointing masonry may be used for repair of adobe cracks. The mortar must be compatible with the historic mortar in color, texture, and composition. <ol> <li>Rake out the cracks to a depth of 2 to 3 times the width of a mortar joint to obtain a good key for the mortar to adhere to the adobe bricks.</li> <li>Remove loose and deteriorated materials. The area shall be free from mortar or paint chips, dust, grease, or oil. Brush clean with natural bristle or nylon brushes (metal bristle brushes are NOT to be used).</li> <li>Lightly spray (do not soak) the area of the patch with water to facilitate a better bond.</li> <li>Apply the adobe mortar to the area, building up to the level of the brick. A trowel or large grout gun may be used to apply new adobe mud mortar.</li> <li>Allow the patching mortar to dry in place a minimum of seven (7) days before continuing with the next phase of wall repair. If wet or unusually humid weather is encountered, or if it is evident for any reason that installation is not sufficiently dry, extend drying time accordingly.</li> <li>After repairs have been completed and the surface has dried sufficiently, proceed to Adobe Coatings (below) and finish to match the existing surface.</li> </ol> </li> </ol>

REPLACING SURFACE COATINGS
<ol type="A"> <li>Mud Plaster: Historically, almost every adobe building surface was coated. <ol> <li>The mud plaster must match the existing plaster in color, texture, and composition. Always replace with like materials and similar techniques. Do not add portland cement or lime to mud plaster.</li> <li>Scrape off as much of the deteriorated mud plaster surface coating as possible without causing damage to the adobe brick beneath. If the bricks are deteriorated, assess the cause of the damage and replace as outlined in Section 04290.01, Adobe Properties and In-Kind Replacement.</li> <li>The area shall be free from mortar or paint chips, dust, grease, or oil. Brush clean with natural bristle or nylon brushes (metal bristle brushes are NOT to be used).</li> <li>Never put another coat of lime or cement plaster over a deteriorated surface coating.</li> <li>Lightly dampen the surface with water; do NOT soak.</li> <li>Apply the mud plaster directly over the brick to form an even coating. Apply in coats in a method similar to application of stucco stone or brick masonry.</li> <li>Once the plaster has been applied, the mud plaster must be smoothed. This is done by hand, sometimes with deerskins, sheepskins, and small, slightly rounded stones. The plaster is smoothed to create a polished surface. In some cases pigments are mixed into the final layer and polished. Finish to match the existing plaster.</li> </ol> </li> <li>Whitewash <ol> <li>The area shall be free from mortar or paint chips, dust, grease, or oil. Brush clean with natural bristle or nylon brushes (metal bristle brushes are NOT to be used).</li> <li>Apply the approved mixture to the adobe wall. It can be either brushed on or applied with large pieces of clean burlap.</li> <li>The Owner should renew or reapply whitewash annually.</li> </ol> </li> <li>Lime Plaster <ol> <li>Replacement lime plaster shall match the existing in color, texture, and composition; consist of like materials to the existing; and be prepared and applied with similar techniques to the existing.</li> <li>Scrape off the deteriorated plaster surface coating without causing damage to the adobe brick beneath. If the bricks are deteriorated, assess the cause of the damage and replace as outline in Section 04290.01, Adobe Properties and In-Kind Replacement.</li> <li>Score the bricks with diagonal hatching for better adhesion. The grooves should be about 1 ½ inches deep.</li> <li>The area shall be free from mortar or paint chips, dust, grease, or oil. Brush clean with natural bristle or nylon brushes (metal bristle brushes shall NOT to be used).</li> <li>Do NOT put another coat of lime or cement plaster over a deteriorated surface coating.</li> <li>Fill the grooves with a mixture of lime mortar and small chips of stone or broken roof tiles.</li> <li>Apply a heavy coating of the lime plaster to the entire wall surface with a trowel and/or brush. Finish to match the historic plaster.</li> </ol> </li> <li>Cement Stucco <ol> <li>Match the existing stucco in color, texture, and composition. Replacement of the stucco shall use like materials and similar techniques.</li> <li>Scrape off the deteriorated plaster surface coating without causing damage to the adobe brick beneath. If the bricks are deteriorated, assess the cause of the damage and replace as outline in Section 04290.01, Adobe Properties and In-Kind Replacement.</li> <li>Cement stucco must be applied over wire mesh that is affixed to the adobe brick with nails. The material is generally used on twentieth-century buildings with stabilized or fired adobe brick. Cement stucco does not form a bond with adobe and requires the mesh to keep it in place. Existing wire mesh and nails should be in good condition and free from rust. The nails are not always stable in adobe; even when very long nails are used, moisture can cause the metals to rust and the nails to lose contact with the adobe.</li> <li>With a trowel apply the stucco to cover the wire mesh. Cement stucco can be applied in from 1 to 3 coats. Finish to match the historic stucco.</li> </ol> </li> <li>Furring Walls. In certain cases, an option may be to fur out the walls prior to applying new lime or cement stucco to a building. The process creates a moisture barrier. Submit evaluation to the Architect for review and approval. Lime and Cement plasters should only be utilized in adobe buildings that were constructed with the same material. <ol> <li>Remove the existing plaster as outlined above.</li> <li>Attach pressure-treated wood lath to the adobe bricks.</li> <li>Apply the lime or cement coating as outlined above. F.	Other Coatings</li> <li>Other coatings such as paints shall be applied to a clean, stable surface. The wall shall be free from mortar or paint chips, dust, grease, or oil. Brush clean with natural bristle or nylon brushes (metal bristle brushes shall NOT to be used).</li> <li>Following manufacturer’s instructions as appropriate, brush the coating onto the wall to achieve an even coating and finish.</li> </ol> </li> </ol>

ADOBE STRUCTURAL REPAIR
<ol type="A"> <li>Foundation Repair <ol> <li>The Contractor shall make an assessment of the type and method of foundation construction. Early adobe buildings can have substantial foundations or barely any at all. Materials range from bricks, fieldstone, cavity walls filled with rubble stone, tile fragments, or sea shells. Adobe buildings were rarely constructed over basements or a crawl space.</li> <li>The Contractor shall assess the cause and nature of the failure. A schedule of work associated with foundation repairs shall be submitted and reviewed by the Architect.</li> <li>Where drainage, changes in landscaping, regrading, and plant removal is recommended, said work shall be reviewed by the Architect.</li> <li>All foundation repairs under this section shall be undertaken with other adobe repairs as outlined in this Section and Section 04290.01, Adobe Properties and In-Kind Replacement.</li> <li>The Contractor shall perform work under this section in phases as approved by the Architect. For large foundation/wall expanses, work shall be done in phases of 2- foot-wide vertical sections separated by at least 4 feet of wall left undisturbed during that phase. Appropriate shoring and bracing shall be provided during the repair work. Foundation repair and related wall repair are performed in each phase, with each phase completed before commencing the following phase. No more than one third of a foundation/wall area shall be undergoing stabilization or replacement at any given time.</li> <li>Foundation repair shall use techniques, methods, and materials as similar as possible to those of the original foundations. Reconstruction of foundations shall be sequenced not only to assure the stability of the structure and protection of personnel during the work, but also to address a sensible order of construction to integrate new work with existing work.</li> <li>Shoring and bracing: The Contractor shall provide sufficient and appropriate bracing on both sides of walls at high and low levels to ensure stability of the walls during repair. The Contractor shall provide bracing diagrams and a safety plan for review by the Architect.</li> <li>Plaster and foundation skirt removal: Remove exterior plaster and foundation materials in areas to be repaired. Saw cut plaster at the top of the foundation to isolate the 2-foot section being repaired.</li> <li>Remove plaster finish and loose sections of the foundation in each section. Breaking up plaster and masonry is to be done by hand to insure that adobe bricks and adjacent wall surfaces are not damaged. The excavated void must have vertical walls and horizontal top and bottom to provide solid support.</li> <li>Retain exterior plaster finish in sections not in the phase of work undertaken. Do NOT remove all plaster at once from the wall to be repaired.</li> <li>Rebuilding the exposed foundation section by replacing masonry units in new mortar. The area should be free of all debris, chips, dust, and dirt. Thoroughly clean edges to assure adhesion of the new mortar.</li> <li>Match the new mortar to the existing in color, quality, texture, and composition.</li> <li>Once foundation repairs have been completed and have cured, the Contractor shall proceed with adobe repairs in the exposed area.</li> <li>Supports and braces can be removed after foundation and wall repairs have been completed.</li> </ol> </li> <li>Structural Wood Replacement and Repair <ol> <li>Adobe buildings can have a variety of structural wood such as horizontal bearing plate near the top of the wall to distribute the weight of the roof, wood sills, windows, and door openings.</li> <li>Wood floors, windows, doors, and other original details shall be retained whenever feasible.</li> <li>Work under this section shall be performed by the Contractor in phases as approved by the Architect. Appropriate shoring and bracing shall be provided during the repair work. Work shall be performed in conjunction with adobe repairs.</li> <li>Structural Wood repair shall use techniques, methods, and materials as similar as possible to those of the original. Sequence wood replacement as part of wall reconstruction not only to assure the stability of the structure and protection of personnel during the work, but also to address a sensible order of construction to integrate new work with existing work.</li> <li>See above and Section 04290.01, Adobe Properties and In-Kind Replacement.</li> <li>See Sections 06300, Wood Treatment and Section 06310, Preservation Treatment</li> <li>After structural repairs have been completed the Contractor shall proceed as above with adobe and finish treatments.</li> </ol> </li> </ol>

FINAL REPORT
The Contractor shall: <ol type="A"> <li>Revisit the site with the Architect and compare the finish and color of the repair to see if the desired affect has been achieved after the brick repairs have been executed and new mortar has cured at least 30 days.</li> <li>Document the work and finished product with photographs taken before, during, and after completion of the work.</li> <li>Provide a written summary of the project and results upon final inspection and approval. The summary shall outline steps taken or new findings not specified in the initial documentation.</li> </ol>
