How to glue PVC: Expert tips for the DIYer

Learn how to glue PVC and you’ll be ready to install PVC boards and trim, assemble patio furniture, and more. It’s just a matter of knowing the relevant details and choosing the best adhesives.

How to use PVC glue: Common applications

When you hear the term PVC, you might immediately think of those white plastic pipes. You’d be correct, but did you know many other household items are made from the same material? Trim boards, siding, fences, patio furniture, upholstery, and toys are just a few common applications. The material is very popular because it won’t shrink, warp, or rot.

So, what is the best adhesive to join or repair PVC products? It depends on the item. Let’s cover a few of those. For gluing PVC pipes, it’s best to use PVC cement that is specially made for that purpose. This is important since the bond needs to be strong and watertight.

To glue PVC boards together, install PVC fence post caps and choose PVC contact cement to assemble PVC furniture (recommendations below). This type of glue will essentially “weld” the parts together for a permanent bond. 

A good-quality construction adhesive will do the trick when gluing PVC to another material, such as wood or metal. Always check the label to ensure compatibility.

How to glue PVC boards together: Simple instructions

Let’s cover installing PVC trim boards such as baseboards or crown molding. 

  1. Gather tools and supplies. You’ll need materials, fasteners, a tape measure and pencil, a miter saw, PVC cement, and construction adhesive. Don’t forget your safety gear: gloves and safety glasses!
  2. Measure and cut a board. Sand any rough edges and wipe away the dust. Always pre-fit the piece before gluing.
  3. Apply construction adhesive to the back of the board where it will contact the wall.
  4. Put the board in place and attach it with a few nails or screws. (Using adhesive greatly reduces the number of fasteners needed.) If not using fasteners, clamp the board in place until the glue sets.
  5. Apply PVC cement wherever one PVC board will meet another, such as at outside corners and mitered corners. Gluing the PVC will create extremely strong joints.
  6. Immediately remove excess adhesive and clean up tools. A damp cloth or mineral spirits will work well.

If you get some adhesive on your hands while gluing PVC, rub it off with a towel and some acetone or nail polish remover. This will soften the glue, and most of it can be wiped away. Then wash with soap and warm water.

How to glue PVC: Choose the best adhesives

Select an adhesive based on the materials that will contact the PVC and the conditions it will be exposed to. 

LePage Heavy Duty Contact Cement bonds on contact to eliminate the need for clamping. It is solvent-based and resistant to heat, moisture, and oil. This product dries clear and will bond to PVC, wood, metal, and laminates, making it a very versatile adhesive for the construction site. It’s available in cans and a squeeze tube.

For small items and quick repairs, you’ll love LePage Super Glue All Plastics. This special formula will bond to most plastics, including those that are sometimes hard to glue. One drop will form a tremendous bond to PVC, polyethylene, polypropylene, and more. It is unaffected by water or freezing temperatures.
