How to Install Screws Into PVC Boards

The term PVC may bring to mind pipes and plumbing, but PVC can be found in many other products. In one common application, PVC is used to make siding for homes. When attaching PVC siding, or when using PVC in other building applications, knowing how to properly use screws with the material is critical.

Whether restoring or replacing siding, it may be necessary to use screws with sheets of PVC.

Step 1

Mark the locations where the screws are meant to be placed. Use a tape measure to find the precise location and use a pencil to mark it to a fine point.

Step 2

Drill pilot holes through the points you just marked. Use a bit slightly smaller than the threaded ends of the screws.

Step 3

Place a piece of scrap wood -- plywood works well -- beneath the PVC sheet if you're going to be drilling all the way through the sheet. Drilling through the sheet into a second material will prevent damage when breaking through the PVC.

Step 4

Use a screwdriver to drive the screws through the PVC sheet. The PVC will be soft enough to be formed into threads but hard enough for the threads to hold.

Step 5

Fill in the screw holes using wood putty, caulk or other material, if desired. Wood putty will offer a smooth, paintable finished surface that hides all evidence of the screw.
