Preparation Work
Porous surfaces should be cleaned with abrasion cleaning followed by blasts of oil-free compressed air. If high-pressure water cleaning is necessary, use caution to prevent water from entering the structure through the existing failed joint.
Exterior surfaces must be visibly dry before installing Dow Corning
123 Silicone Seal.
Nonporous surfaces should be cleaned using the two-cloth solvent wipe as outlined in Dow Corning’s sealant application guidelines.
Masking Apply masking tape in areas of high visibility to ensure good aesthetics (see Figure 2).

The Dow Corning product is applied in strict compliance with Dow Corning's published or electronic recommended application procedures, and b.
The sealant and coating are used with compatible materials and substrates, and (testing/evaluation is required to obtain this warranty if the surface is not recommended in our Surface Preparation Guide which is available in published or electronic form), and c.
The sealant and coating are applied within its stated shelf life, and d.
Field adhesion tests are made, documented, retained, and submitted to Dow Corning upon written request as outlined in our Field Adhesion Test Procedure in order to confirm adhesion under site conditions.
LIMITATIONS
This Warranty specifically excludes adhesive and/or cohesive failure of the sealant due to: a.
Use of the sealant as a structural or load-bearing sealant. b.
Natural causes including but not limited to lightning, earthquake, hurricane, flooding, tornado, and fire. c.
Improper installation. d.
Movement of the structure resulting in stresses on the sealant, 123 seal and/or coating which exceed
Dow Corning's published specifications for elongation and/or compression for the sealant, 123 seal and/or coating, including but not limited to structural settlement, design error, or construction error. e.
Faults attributable to workmanship including but not limited to improper surface preparation, use of non-approved materials, insufficient coating thickness, or deviation from Dow Corning recommended application procedures.
And does not cover damage to, or failure of, the sealant due to: a.
Disintegration, deterioration, or failure of the underlying substrates (including but not limited to cracking, blistering, or peeling).

b.
Mechanical damage including but not limited to surface abrasion, individuals, tools, vandalism or other outside agents. c.
Changes in appearance of the sealant, including but not limited to, natural weathering (whitening, chalking, fading, staining), the accumulation of dirt or other contaminants deposited on the sealant from the atmosphere, or from incompatible substrates. Changes in the appearance of the coating and/or
123 seal, including but not limited to, natural weathering (whitening, chalking, fading, staining), the accumulation of dirt or other contaminants deposited on the coating and/or 123 seal from the atmosphere, or from incompatible substrates.
This warranty excludes costs and damages attributed to mold, mildew and/or fungus.
The warranty also specifically excludes costs and damages resulting from the presence of any hazardous materials in the existing sealants, coatings, substrates, or the environment/location in which the sealant is installed or applied, including but not limited to: a.
Establishing appropriate safe handling procedures for the removal of sealants and/or coatings. b.
Removal or disposal of the existing sealants and/or coatings. c.
