Best Glue for PVC Pipe Repair – All You Need to Know, Tips & Product Guide

Sometimes, pipes break down, and you get water leaks in your house.

Whether you need to seal or glue PVC pipes, you wouldn’t want to risk further damage due to a failed reparation.

That’s why you must use the right adhesive for PVC applications.

This is what we’ll talk about in this article— the best PVC glues and how to use them.

PVC is among the most difficult plastics to bond. It might be tempting to use any good ol’ plastic glue.

But you’ll only sabotage your repairs. PVC is very hard, non-porous, and highly resistant.

Also, pipes require high water and impact resistance. For a long-lasting fix, you should only opt for the best, most compatible, high-adherence glues.

Recommendation – Oatey 31018 Hydraulic Cement is the best glue for a one-and-done application. It offers an affordable, easy, and high-strength fix, and you can safely use this PVC cement for conduit, pressure, and DWV pipes. It’s both 100% water-proof and contact-proof. It easily locks pipes in place and prevents any movement or leaks.

Suitable Glues for PVC

You’ll need to ensure that your adhesive meets certain criteria for the best bond and repair results.

Adherence to PVC and bond strength are the most important. Water, heat, and pressure resistance are also necessary for a long-lasting pipe fix.

Considering all this, the following adhesives make the best options.

PVC Cement

PVC cement is the first and most obvious choice. This glue has the highest strength, but that’s not to say that silicone glue can’t form powerful bonds.

Read more about the above in our guide on how to glue silicone.

The main advantage of PVC cement is its high surface compatibility.

It adheres easily to smooth and hard plastics and forms tough, unbreakable bonds.

This is the best option if you need to lock pipes in place and keep them from moving.

PVC cement is a heavy-duty adhesive; once it sets, the materials become immovable.

This might be an issue if you ever need to work on the pipes again or if you need a more flexible bond.

This PVC adhesive has good pressure and water resistance, so you’re guaranteed a durable fix.

However, nothing great is without downsides. Because this adhesive is usually thick, it takes a long time to dry and set.

That means you’ll have to spend a while clamping materials before curing.

Silicone Glue

Silicone glue is the second-best option for strong, durable bonds. It has some additional perks, such as its high flexibility.

Silicone glue will be your best bet if you need a powerful bond that’s not too rigid.

It’s also a great sealant and waterproof, so you can use it to fix leaking pipes.

However, silicone glue might be a bit more difficult to use compared to PVC cement.

It doesn’t have the best adherence to PVC, so you’ll need to prep the surface with a bonding primer or sand down the surface of the material to make it rougher and more adherent to the glue.

You must also be very careful when spreading the silicone glue on the pipes.

Silicone tends to shrink as it dries, and this could be a problem when you’re trying to seal extensive areas.

For best leaks repairs, you must also account for this shrinking effect if you don’t want a surprise later.

The glue is very easy to use but may become messy if you’re not careful.

The PVC pipe needs to be dry before using Loctite Clear Silicone Sealant.

It doesn’t do well in damp environments when you first apply it.

But once it sets and cures, the adhesive becomes completely waterproof, and you can even submerge it in water with no problems.

It doesn’t do well in high-temperature environments, though.

Why Do You Need to Glue PVC Pipes?

Not all situations demand PVC-specific adhesives or cement. Sometimes, you could do with a general glue that doesn’t have too much tensile strength.

But some circumstances require more holding strength, higher durability, and more resistance to water, heat, and solvents.

For instance, glue is a bad option if you’re planning to use PVC in a mobile setting where you know you need to dismantle and reconstruct it back again.

If it’s a non-essential and dynamic project, then using glue will only make everything more difficult.

But glue or PVC cement is necessary if you’re working on a static and important large-scale project.

You don’t want your PVC pipes to collapse, resulting in material losses.

Even if it starts leaking at some point, you’ll have to repair it again and again.

That wouldn’t happen with a good waterproof PVC glue. I recommend paying more for a proper adhesive and avoiding future expenses with repairs.

Tips for Gluing PVC Pipes

When you want to glue PVC pipes together or bond them to other materials, you’ll need to use specific PVC glues or types of cement.

I recommend reading the usage instructions and specific requirements for every glue you buy.

But there are some common-sense steps you can take when working with PVC cement.

First, you’ll most likely need a primer before applying the glue. The primer substance will make the glue adhere better to the PVC pipe and other materials.

You can also sand down the surface of the pipe to make it more abrasive. The glue will better grip the material if the surface is rougher.

That’s true for most glues, whether we’re talking about wood glue, PVC cement, or plastic glue.

When you make the surface more abrasive, the glue can get into those crevices and cracks better.

You should also do the same when you want to fill gaps and holes.

Before applying the adhesive, clean the pipe of any impurities.

The glue must be in full contact with the surface to obtain a strong and durable bond.

Any impurities between the glue and surface material will weaken the bond.

You can wipe the surface with a damp cloth to remove debris and then leave it for a few minutes to dry out.

If you have to sand down the surface, then the debris will be present on the surface, so do a proper clean-up afterward.

Now comes the gluing part. You’ll have no problems bonding the materials if you read the adhesive instructions carefully.

Applying the glue is as simple as it sounds, and the clamping part isn’t difficult.

I recommend following the safety instructions closely so as not to risk your health when using the glues.

Always wear gloves and eye protection to protect yourself from direct contact with the glue.

Some adhesives like superglue set very quickly and will harden in a few seconds. Washing it out will be a hassle afterward.

Moreover, most glues will irritate your eyes and skin and cause immense damage to your internal organs if ingested.

Don’t ingest any adhesive! I also recommend wearing a respirator and working in a well-ventilated environment if you’re using a toxic industrial-grade adhesive.

Lastly, some glues may be flammable, so avoid using ignitable tools around them!

PVC cement is generally non-flammable, so you’re safe using Oatey 31018 Hydraulic Cement or other types of cement.

Wrap-up

Bonding PVC pipes is less difficult than you think. As always, you need the proper adhesive to work efficiently.

Oatey 31018 Hydraulic Cement is the best adhesive for PVC pipes.

The waterproof concept and contact-proof bond prevent leaks or unnecessary movements.

The permanent bond will keep the pipes in place for a long time!
