Then bolt the tv mount to the 2x4s.
Mounting tv to vinyl siding.
Bolt two 2x4s horizontally to the wall studs on top of the vinyl siding using lag bolts.
Video of the day.
You could put a few washers on the lag bolts underneath the 2x4 if you wanted spacers to keep from crushing the vinyl.
Mounting tv against vinyl siding i don t like the idea of cutting big gashes into the vinyl.
Drill four 1 2 holes into the vinyl and settle some spacers thick enough so they clear the vinyl through those holes to the solid decking underneath.
If you want to hang something from your vinyl siding don t even think about drilling through it to attach a hook to the sheathing.
You can t anchor exterior features directly to the vinyl siding panels.
This renders the siding vulnerable to moisture and voids the warranty even if you seal the hole.
Your exterior features are anchored to the mounting block and in turn the structure of the house.
