PART 3 EXECUTION
3.1 EXAMINATION FOR FIELD TREATMENT
A. Do not begin application until substrates have been properly prepared or environmental conditions are outside of the manufacturer's absolute limits.
B. Examine for wet conditions; do not apply product to substrates that are wet or have been wet, unless they can be dried to the maximum moisture content as specified by the manufacturer
A. Clean surfaces thoroughly prior to application of fire retardant
B. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
3.3 FIELD CUTTING TREATED LUMBER
A. Field cutting of previously treated lumber for required lengths, drilled holes or notching shall have exposed lumber areas recoated in the field; ripping or milling of lumber after treatment must be re-treated by the certified applicator
3.4 PRODUCT APPLICATION
A. Thoroughly mix product before application. After the application of 1500° Series FRV has been completed, allow to dry a minimum of 48 hours before applying 1500° Series FRT. Remove all dust, dirt and foreign matter from the surface. Apply product at a coverage rate of 600 square feet per gallon by brush, foam roller, airless or conventional-spray apparatus. In hard use areas specified apply a second coat at the same coverage rate. Allow the surface to dry a minimum of 24 hours between coats. Apply product when air temperature is between 50 F (0.6 C) and 120 F (49 C). The maximum moisture of the substrate to be treated prior to application of product shall not exceed 25 percent.
