Field Cuts
Regardless of the time of the year of the installation, all field cuts must be finished. The end grain of all wood
products absorbs liquids up to 250 times more rapidly than other wood surfaces. 100% acrylic-latex primer is
acceptable as long as it is able to properly cure according to the primer manufacturer’s instructions. However,
where temperatures drop below 50 degrees Fahrenheit either during application or within the curing period, use
an alkyd oil wood primer to coat end grain exposed by jobsite cuts. Siding with end cuts coated with alkyd oil
primer can be installed before drying without compromising the coating’s effectiveness. Above 50 degrees, a high
quality 100% acrylic-latex primer will suffice to coat exposed end grain if allowed to dry before installation. With
either primer, follow manufacturer’s recommendations.
