Working With PVC: Sanding

Polyvinyl chloride, or PVC, is a plastic building material that comes in sheets or pipes. The pipes are most commonly used for plumbing work, but can be implemented in other building or craft projects. Although PVC pipes come in several sizes, you may need another a size not available off the shelf. You could also want to remove the manufacturer's markings before installing the pipes, or smooth any rough cut edges. Sanding the pipes will help you accomplish these tasks, and the same techniques can be applied to sheets of PVC as well.

Pipes made of PVC can be used for more than plumbing.

To Remove Markings

Step 1

Cut the PVC to the size you need. This will make it easier to work with because the smaller pieces will be less cumbersome than the whole pipe or sheet.

Step 2

Sand the entire surface with fine-grit sandpaper or sanding pads. Use a flexible sanding pad to curve the sandpaper around a pipe. This will remove the markings faster and in a more even fashion than sanding a bit at a time with a flat sander.

Step 3

Clean the PVC by brushing it with a dry cloth. This will remove the sanded dust and give you a clean surface.

Sanding Down to Another Size, or Sanding Rough Edges

Step 1

Cut the PVC to the length you need. Again, working with smaller pieces will be more comfortable for you.

Step 2

Set up your work area. Sanding PVC down more than the amount required for removing outer marks can be extremely time-consuming and tiring by hand, so it is best to work with a machine sander. If you are working with a large machine, set it up and check the sanding belts or paper before you begin. If you are working with a smaller machine, such as a hand drill with a sanding bit, secure your PVC in a clamp so it will not move while you are working.

Step 3

Sand the PVC a little bit at a time until you get the desired results. PVC heats up when it is sanded, from the friction. This can cause the PVC to warp, which can ruin your project or endanger you, if it breaks and causes you to come in contact with the machine. Sand until it gets hot. Then take a break for it to cool a bit before moving on.

Step 4

Remove the PVC from the machine or clamp and clean it with a dry cloth. Once you have the desired shape, edge or texture, you can complete your project.
