The block surface is to be covered withplastic during the first 24 hours to simulate water curing
19、unlessa curing compound is included in the testing.5.4 The block shall be removed from the form after 24 hoursand wet cured in accordance with ACI 308 or Practice C192/C192M.5.5 If a curing compound is to be used, apply the compoundto the broom finished surface immediately after finishing and toall
20、other surfaces of the block within 2 hours after its removalfrom the form.5.6 Allow the block to cure for 28 days in accordance withACI 308 before application of the coating system unlessotherwise specified.5.7 A suitable hanger compatible with the testing apparatusshall be affixed at the mid-point
21、of the upper end of the blockas appropriate when required by the test method.6.

Any special procedures or conditionsshall be noted in the documentation including thinning, mixing,use of accelerators, drying/curing times, force curing, agingbetween coats/systems, and intermediate surface preparations.8.2 The film thickness range shall be representative of thespeci
27、fic work for which the testing is being conducted.8.3 Test samples for painting test programs may includesimulated aging of the existing coating, intermediate surfacepreparation and wide ranges of coating film thicknesses.Additional special requirements may be defined by the lic-ensee.8.4 All surfac
28、es of concrete blocks shall be coated whentesting in accordance with Test Method D3912. The upperand/or lower ends of the blocks shall be left uncoated for allother testing.9. Documentation and Records9.1 The manufacturers product identification, includingcolor, shall be reported.9.2 The procedures
29、and conditions used for the test samplepreparation shall be documented. As a minimum the documen-tation shall include all sample preparation times and dates,surface preparation details; thinners, accelerators, additives,reinforcement, and fillers added during the mixing and appli-cation process; coa
30、ting/ lining sequence and individual dry filmthickness ranges of each coat, total thickness range, environ-mental conditions, and product batch identification.9.3 Record any deviations or non-conformances.10.
