does epoxy putty work on plastic?

Epoxy putty is a clay-like material that comes in two sticks. When you mix them together, the putty becomes pliable and can be applied to anything you want to repair.

It dries in 30 minutes and can be sanded, drilled, or painted after drying. The putty also hardens underwater and is waterproof, chemical-resistant, impact-resistant, and durable.

As long as you follow these steps, your cracked plastic will mend itself like new!

Does putty work on plastic?

Epoxy putty is an adhesive that’s often used to fix cracks, chips, and holes in surfaces you may think are too broken to repair.

It’s also known for being able to create a strong and sturdy bond with a variety of materials, including plastic.

When it comes to fixing less-than-perfect plastics like your old sunglasses or the cracked bumper on your car, read on for everything you need to know about using epoxy putty on plastic surfaces.

Does epoxy putty work on plastic?

Can you use metal epoxy putty on plastic?

Short answer: yes!

Longer answer: Why, yes you can! It’s an easy fix; the repair is actually better than new since it adds significant strength to the original plastic.

The putty also works on polyurethane, polyethylene, and polypropylene. However, it will not work on silicone or Teflon.

What does epoxy putty not stick to?

Epoxy putty does not adhere to many materials, including plastic. This means that unless you want a permanent bond, it’s best to avoid using epoxy putty on objects made of plastic.

Some other materials that epoxy putty is incapable of sticking to include glass, Teflon (and other forms of PTFE), waxed paper, and rubber.

What kind of epoxy can I use on plastic?

Epoxies come in a variety of different forms. Whereas many epoxy types of glue are formulated for use on metal, plastic, or wood and can’t be used on other materials, epoxy putty is created to work with nearly any surface.

It’s best described as a clay-like substance that comes as two parts: one part is the hardener, while the other part is the base. When mixed together in equal parts, they form a durable puttied material that can be molded into shape and will eventually dry rock-solid.

Will plumbers putty damage plastic?

Plumbers putty can be used to temporarily bond plastic together, but it is not a permanent solution. Because a plumber’s putty is not as strong as other forms of epoxy, it will wear down over time, especially if the surfaces are exposed to water.

It won’t damage your plastic, but you may find yourself having to reapply the epoxy more frequently than you want.

Does plumbers putty harm plastic?

Plumbers putty is not recommended for use on plastic as it can damage the material. Plumbers’ putty has a petroleum base and will cause deterioration in the plastic.

Plastic is a porous material and over time can absorb the oil in the putty, causing damage to occur. Another reason to avoid using plumbers’ putty on plastic surfaces is that plumbers’ putty removes paint.

If you intend to repaint your plumbing fixtures, you should avoid using this product on them at all costs!

What can be used in place of plumbers putty?

So you’re probably wondering, what can be used in place of plumbers’ putty? There are a few options to consider before turning to epoxy putty.

First off, there’s silicone sealant. Admittedly not cheap (a single tube will cost you about $5), and it’s a great option for anyone looking to get the job done right.

Silicone sealant is very durable, with most brands boasting a life span of up to 50 years! It also comes in a range of colors, so if you’re looking for something that blends in well with your kitchen sink or bathroom basin, look no further than silicone sealant.

Second, on the list is gasket maker. This material does exactly as its name suggests it makes gaskets! Gasket makers work by being applied around and between pipes and then hardened as they dry.

The main difference between this material and plumbers putty is that it doesn’t need any more tightening after installation because it hardens completely on its own within 48 hours after application.

Finally, we have petroleum jelly and thread seal tape – two materials that are very different but both serve similar purposes when sealing plumbing joints together securely without allowing water leakage through them during use or under pressure

How do you apply epoxy putty to plastic?

We’ve been interested in a long time in putting epoxy putty to work on plastic. It’s a handy tool for many projects, but even though it’s super easy to use and can be quite durable, we ran into trouble successfully applying it to plastic in the past.

We’d try it out, but more often than not, the putty would end up cracking or breaking on the surface of our project.

The solution: We tried using a different kind of putty this time around—a thicker version that’s designed specifically to bond with plastic.

The result? This time around, we had no problems at all! It was as if epoxy putty knew what we wanted and exactly how to do it. The material worked great!


  • Epoxy putty is not a good choice for plastic repairs. Plastic is a flexible material that is not well suited for rigid epoxy putty repair. There are many other adhesives that are better suited for plastic repairs, as well as other types of epoxy putty. Plumbers putty may be ideal to temporarily fix a plastic pipe or drain, but it will require replacement at some point in the future.
