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 ripping or milling of lumber after treatment must be re-treated by the certified applicator
3.4 PRODUCT APPLICATION
A. Materials to be treated shall be free of dust, dirt, wax and oil. Any loose peeling or powdery varnish shall be removed from the surface prior to treatment. Repair all cracks, holes and other surface irregularities. Allow to dry, sand lightly. New previously uncoated surfaces should be sealed prior to application with 1500° Series FRV-GF diluted with one pint of mineral spirits per gallon or other suitable non-lacquer type sealer. All glossy or smooth surfaces should be dulled with sandpaper or steel wool. Thoroughly mix product before application. Apply product at a coverage rate of 400 square feet per gallon by brush, foam roller, airless or conventional-spray apparatus. Allow to dry at least 24 hours or until hard. Lightly sand, clean dust from the surface and apply a second coat at the same coverage rate. 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. In field applications, certified applicator shall perform field testing when required by the authority having jurisdiction.
