C-clamp or vise (optional)
Plexiglas is a type of durable acrylic with a wide range uses. Because of its transparent quality, it is often used to make window panes or aquarium siding. Polyvinyl chloride (PVC) is a strong, versatile plastic commonly used in residential plumbing. PVC's rigidity also makes it ideal for automotive body kits, prosthetic limbs and children's toys. To create a lasting bond between Plexiglas and PVC, you need an epoxy made for use on plastics.

Mix 1 cup of warm water and several drops of liquid dish soap. Clean the Plexiglas and PVC thoroughly to remove any grease, dirt or other residue.
Rub the parts of the plexiglass and PVC that will be bonded with a piece of fine grit sandpaper. Slight coarseness will strengthen the epoxy's adhesion.
Wipe any plastic dust away from both surfaces using a wet rag.
Spread a thin layer of epoxy onto the plexiglass. Your area of coverage with the epoxy should be relative to the size of the piece of PVC you are attaching.
Press the PVC firmly onto the layer of epoxy.
Secure your Plexiglas and PVC assembly in a C-clamp tool or bench vise to hold the assembly secure while the epoxy cures. Placing the assembly under a heavy object, such as a cinderblock, works as an alternative.
Allow the epoxy to cure for the time suggested on the container.
For best results work in a well lit, ventilated area.
Avoid clamping the assembly too tightly. Excess pressure may cause the PVC or Plexiglas to crack.
Do not inhale or ingest fumes from the plastic epoxy.
Do not allow children or pets near your work area.
