When coatings are applied in accordance with Section 3.5 or Section 3.6 for Fire Resistance, the applicator shall be certified by No-Burn®, Inc. Copies of this report and the No-Burn®, Inc. instructions shall be available at the job site. Where conflicts occur, the more restrictive shall govern. Before and during coating application, substrate surfaces shall be dry, clean, and free from loose debris, dirt, grease, oil, and all prior coating materials such as paint, stains, and sealers. The substrate shall not have, nor have been exposed to, treatments, chemicals, coatings, etc. Visual observation of the applied coatings varies. Opaque coatings will result in a distinctive white color. Transparent coatings may result in a distinctive color dye on the substrate. For verification of the wet applied thickness, a standard painter’s thickness gauge shall be used during the application. The finished dry mil thickness will be 0.40-0.70 times the wet mil thickness. When verification of transparent coatings is required by the building official, field testing shall be conducted as follows: flame from a propane- fueled torch shall be applied to the coated area and to a sample of uncoated substrate for a minimum of 10 seconds. The presence of the coating shall be observable through the comparison of the reactions of the coated and uncoated substrates to the flame. The coatings shall be applied only to the specific substrates listed in Tables 1 through 9 of this report. Immediately before placing the coatings, the applicator shall verify the moisture content of the substrates, as applicable, in accordance with Table 1, Table 2 (SIPs only), Table 4, or Table 5 of this report. Substrates shall be in their final position in the building, directly exposed to the interior, protected from the weather, in conditioned and unconditioned locations. Surface and ambient temperatures before and during application shall be 40°F (4.4°C) minimum. Surface temperatures shall not exceed 100°F (37.7°C) during application. Cure time is 24 hours minimum. The coatings shall be applied at an application rate set forth in Table 1, Table 2, Table 3, Table 4, Table 5, Table 6, Table 7, Table 8, or Table 9 of this report by spraying, roller, or brush. When coatings are applied in accordance with Section 3.5 and Table 4 or Section 3.6 and Table 5 of this report, the frequency of thickness measurements with a wet film thickness gauge during the application of each coat shall be at a minimum, measured once every 100 ft2 (9.29 m2) of surface area. 4.2 Design: No-Burn® Plus, No-Burn® Plus ThB, No-Burn® ThB Spray SealTM, No-Burn® Plus XD, No-Burn® Plus Mih, No-Burn® Original, No-Burn® Original Mih, No-Burn® Wood Gard, and No-Burn® Wood Gard Mih shall be applied in one coat and may be overcoated with latex paint manufacturer’s instructions. 5.0 LIMITATIONS The No-Burn® coatings described in this report comply with, or are suitable alternatives to what is specified in those codes listed in Section 1.0 of this report, subject to the following conditions: Page 4 of 15 Number: 305 Revised: 10/15/2024 Valid Through: 03/31/2025 Originally Issued: 03/21/2014 5.1 The coatings shall be applied in accordance with this report, the manufacturer’s instructions, and the applicable code.
