There are at least three alternative ways to do it.
Mounting tv to vinyl siding.
You can t anchor exterior features directly to the vinyl siding panels.
Instead cut a hole through the siding and affix a mounting block to the underlying sheathing or framework of the house.
Video of the day.
Bolt two 2x4s horizontally to the wall studs on top of the vinyl siding using lag bolts.
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 to outdoor wall that is vinyl siding posted by miketh3tiger on 6 13 17 at 7 39 pm to jojothetireguy my plan is to build a box to mount the tv in and mount the box to studs with a 3 4 gap between the vinyl and the box.
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.
Then bolt the tv mount to the 2x4s.
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.
