a. Dates when surface preparation was performed. <br />b. Type of surface preparation. <br />C. If surface contaminants such as engine oil were present on the slab prior <br />to surface preparation and cleaning. <br />d. If surface contaminants remain on the slab after surface preparation and <br />cleaning. <br />e. Relative humidity of the slabs prior to application of deck coatings. <br />f. Time, date, temperature, precipitation, relative humidity, and sun <br />exposure when deck coatings were installed. Note if conditions changed <br />during the installation. <br />g. Type of materials used for deck coating installation and wait times <br />between each application. <br />h. Deck coating dry mil thickness and if the thickness complies with <br />specified requirements. <br />i. Test dates, test locations, and adhesion results (whether deck coating <br />failed to adhere to substrates or tore cohesively). <br />j. Names of persons who performed surface preparation, who <br />performed relative humidity testing, who installed deck coatings, and <br />who performed adhesiontests. <br />Repair deck coatings pulled from test area by applying new deck coating following <br />same procedures used originally. Ensure that original surfaces are clean and that <br />new deck coating overlaps original deck coating. <br />B. Deck Coating Slip Resistance Testing: Field test deck coating slip resistance as follows: <br />1. Extent of Testing: Test mockups and completed deck coatings as follows: <br />a. Perform 1 test. <br />2. Test Method: ASTM F 1679 under wet conditions. <br />3. Inspect deck coating for variations in aggregate distribution. Locate tests at areas <br />with high density of aggregate and with low density of aggregate. Record results <br />in a log and report on the following: <br />a. Test dates, test locations, and slip resistance results. <br />b. Names of person who performed tests. <br />C. Approximate area (square feet) of deck coating that exhibits a low <br />density of aggregate, an average density of aggregate, and a high density <br />of aggregate. <br />4. Repair deck coatings pulled from test area by applying new deck coating following <br />same procedures used originally. Ensure that original surfaces are clean and that <br />new deck coating overlaps original deck coating. <br />C. Evaluation of Field Test Results: Products not evidencing adhesive failure from testing <br />or noncompliance with other indicated requirements will be considered satisfactory. <br />Remove products that fail to adhere to substrates during testing or to comply with other <br />requirements. Reapply mockups and retest until test results prove products comply <br />with indicated requirements. Do not use products that fail to adhere to substrates during <br />testing. <br />IRC -1801 Indian River County <br />Courthouse Parking Garage <br />Rehabilitation 07 90 20-7 Garage Waterproofing Systems (Revision 1) <br />
