Preparing Wall Surfaces
New Construction
Make sure all studs are straight and true. Correct any bowed
studs.
NOTE: Vinyl siding must be applied over a rigid sheathing
that provides a smooth, flat surface or an underlayment
(such as wood, wood composition, rigid foam or fiber
sheathing) that is no more than 1" thick. Vinyl siding
cannot be applied directly to studs.
Make sure sheathing is fastened securely to studs.
If you’re planning to use a conventional house wrap or building
felt, apply according to the manufacturer’s recommendations.
In all cases, however, install the products so they are secured
firmly to the substrate so that they provide a smooth, even
surface for the final siding installation.
Before applying siding, make certain substrate is watertight.
In order to be properly protected from precipitation, the
substrate may need to be properly flashed around areas
such as windows, doors, other openings and corners so as
to shed water to the exterior. The siding alone is not meant
to be a watertight barrier.
Drop-In Foam Backer Boards
Some drop-in foam backers can restrict the movement of vinyl
siding. Therefore, Wolverine vinyl siding may not be applied
over any drop-in foam backer other than a contoured drop-in
foam backer designed specifically for each profile.
IMPORTANT: Wolverine will not accept any responsibility or
liability in the event the drop-in foam backer restricts the
movement of the vinyl. The use, fit, and performance of the
siding backer board is the responsibility of the installer and the
backer board manufacturer.
NOTE: Contoured drop-in foam backer boards are not a
substitute for rigid foam sheathing.
Home Improvement Projects
You can prepare your current siding surface to receive vinyl
siding in one of three ways:
Strip off old siding and level the wall. If felt paper covers the
wall, you have two alternatives: either strip it off completely or
staple or nail it to create a smooth surface. If there is no solid
sheathing under the old siding, you must apply it as described
in the instructions for New Construction, above.
