Preparing Wall Surfaces
For the most part, the wall preparation instructions given for horizontal siding also apply to vertical applications. The key requirement, of course, is that you start with a smooth, level and rigid substrate (plywood, wood composite, rigid foam or fiber sheathing).
NOTE: Never install vinyl siding over open furring strips or studs. Always check with your local building code official.

With vertical siding, however, you may have to complete an extra step to provide solid nailing points along the vertical edge of the siding panel. The need for this added step depends on the type of substrate used and the nature of the construction project.
With new construction or remodeling using plywood or wood composite, there are no additional steps. You can nail into plywood and wood composite substrates at any point as long as you do not exceed 12" on center.
In new construction using rigid foam or fiber sheathing, you must install solid wood nailer strips horizontally to studs before applying sheathing. Use 1" x 3" wood furring positioned 12" o.c.
When remodeling over existing wood siding, you must apply rigid foam or fiber sheathing, shimming if necessary to create a level surface.
When remodeling over brick, block, stucco or irregular wall surfaces, apply furring strips horizontally to create a level surface; then apply rigid foam or fiber sheathing. See “Tips for applying wood furring” on pages 31 to 32 and “Applying over stucco” on page 32. When reviewing the illustrations for those sections, remember that furring strips must be applied horizontally.
Marking a base line
The procedure is virtually the same as that described earlier. However, instead of snapping a chalk line
NOTE: When installing vertical siding in high wind areas, position the fasteners at the top two nail slots of the panel.
