COLOR MATCHING
When working with colored mortar, uniform color requires consistent material proportioning. With SPEC MIX this isn't a problem. SPEC MIX colored mortar consists of preblended Portland cement or mortar cement, lime and sand to produce uniformity from batch to batch. No field measuring is required. The pigments are specially blended to ensure maximum color effect and proper dispersion throughout the batch.
Containing only finely milled synthetic iron oxides, the strongest and most stable colors available, SPEC MIX colors are lime-proof, sunfast and inert. The product is environmentally safe and, in every application, SPEC MIX meets or exceeds the criteria of ASTM C 270. SPEC MIX preblended colors cover the full range of the color spectrum: brown, buff, tan, black, yellow, orange, red and white. To achieve just the right masonry look, custom colors are available upon request. Your special color is perfectly matched every time, allowing complete control of your projects.
All SPEC MIX colors are available in appropriate strengths and proper mix designs.

          B.Remove efflorescence from masonry wall exposed in the finished work in accordance with manufacturer's recommendation and NCMA TEK Bulletin #8-3A.
 
          C.Remove dirt or stains from masonry walls exposed in the finished work in accordance with the manufacturer's recommendations and NCMA TEK Bulletin #8-2A/
          ** NOTE TO SPECIFIER ** Delete the following paragraph if no Integral Water-repellent Mortar.
 
          D.Promptly remove excess wet mortar containing integral water-repellent mortar admixture from the face of the masonry as work progresses.
 
          E.Comply with applicable environmental laws and restrictions.
 
          3.4PROTECTION
 
          A.Protect installed work from damage due to subsequent construction activity on the site.
          ** NOTE TO SPECIFIER ** Delete the following paragraphs if Field Quality Control is specified in another masonry section.
 
          3.5FIELD QUALITY CONTROL
 
          A.Tests:
          1.Frequency: As determined by the Architect based upon total time for construction of masonry with not less than two tests per each level of masonry construction, foundation to roof or floors.
          2.Testing Laboratory: Independent of the Owner, Architect and Contractor; the testing laboratory, in addition to meeting requirements of ASTM E-329, and must be an approved laboratory competent to perform cement physical testing. All tests must be performed in strict accordance with the applicable ASTM standard.
          3.Distribution of Results of Tests: Within 24 hours of results of tests, copies of the results shall be submitted to the Architect, Contractor, masonry contractor, and the grout supplier if applicable.
 
          B.Mortar Testing:
          1.Testing per ASTM C 780 when the property specification is specified.
          2.When the proportion specification is specified, field quality control shall be performed by inspection only.
          3.For determining hardened mortar properties, prepare three test specimens for each test age and property. A strength test shall be the average of the strengths of the specimens at the age specified.
          4.Specimens shall be tested at 7 and 28 days.
          5.In case of dispute, the mortar proportions must be tested in accordance with the property specification of ASTM C 270.
 
          C.Grout Testing:
          1.Testing per ASTM C 1019.
          2.Three test specimens shall constitute one sample. A strength test shall be the average of the strengths of the specimen tested at the age specified.
          3.Specimens shall be tested at 7 and 28 days.
          4.The compression strength will be considered satisfactory if the average of three consecutive tests of the grout is equal to or greater than the specified strength and no individual strength test falls below the specified strength by more than 500 psi.
