How to Glue HDPE: The Easy Way

In the construction industry, it is important to use the right glue for each application. The wrong adhesive can ruin a project and take a lot of time to repair. For example, if you are gluing HDPE (high-density polyethylene) it is best to use an epoxy that has high heat resistance. In this blog post we will be discussing how to glue HDPE: the easy way!

What Is HDPE

HDPE is an abbreviation for high-density polyethylene. It has a low moisture absorption, which makes it resistant to weathering and corrosion. HDPE is used in the construction industry because of its durability and affordability.
HDPE differs from LDPE (low-density polyethylene) because it is denser, which makes HDPE more durable and less susceptible to breakage.

HDPE has a variety of uses such as pipe for water distribution systems or irrigation piping in greenhouses. It can also be used as vegetation fabric in landscaping applications.

What Glue Works on HDPE

Hot glue, super glue, and epoxy are all good choices for gluing HDPE.
Hot glue melts the surface of HDPE and attaches to it. It’s a good choice for small or light objects, but not very strong.

Super glue is also known as “instant bond”, because you can connect two surfaces instantly with just one drop on each side. This type of glue works well when gluing together larger pieces, such as pipes or sheeting materials where strength is needed over time.

Epoxy resists water and will stay bonded in damp conditions that would cause other types of glue to fail; making this an excellent option when attaching PVC pipe joints underwater for plumbing systems. Epoxy adheres better than most other kinds of adhesive do so if your project involves moving parts like hoses or fittings.

Hot glue

Hot glue for HDPE is a very good choice. You might also want to experiment with polyurethane glue, which is what HDPE manufacturers recommend for woodworking projects made from HDPE sheets and panels.

The downside of hot glue is that it begins drying as soon as you apply it, so your final project may not be exactly the way you wanted it to look if mistakes are made in the gluing process. Polyurethane glue has a longer set time before becoming completely dry; thus giving you more time to make adjustments on your work surface without worrying about how they will affect the finished product.

How to glue HDPE together with Hot Glue: Step By Step

  1. First, clean the area where you will be gluing with a cloth or paper towel
  2. Next, place one piece of HDPE on top of another and align them as close together as possible
  3. Now push down hard to flatten out any air bubbles that are visible in between the two pieces. Once there’s no more room for an air bubble, use your glue gun to put adhesive all over both edges and then press tightly again.
  4. Allow it about 15 minutes to dry before flipping over (or touching) the newly glued surfaces.

Super Glue

Many adhesives work well on HDPE, such as a glue stick or hot glue. However, if you’re looking for something more permanent that will really keep the plastic together then superglue is your best bet.

Superglue works by chemically reacting with the material it’s being applied to and fusing its molecules together in a cohesive bond that has proven not to break down over time like other glues do. It also doesn’t drip like some types of adhesive can which makes applying it easier than many alternatives available today. Plus, this type of glue provides instant bonding so there is no waiting around for anything to dry before handling whatever was glued together.

If you are using hdpe pipe which needs to be glued together for strength then using glue may be a better option instead of tape.

How to glue HDPE pipe together with super glue: Step By Step

  • Clean both surfaces with alcohol or acetone before applying any adhesive type, removing as much dirt and residue from surface so that it’s clean and free of possible contamination
  • Apply superglue in a thin layer evenly over one surface (either side) at room temperature; avoid getting too close to edges where there is no material left on either sides since this could cause an unwanted chemical reaction between the different substances; few drops will suffice – let dry for 60 seconds until tacky if necessary because sometimes hot temperatures can make some types of glue not set quickly enough
  • Align the surfaces to be glued together; hold them in place for up to 30 seconds and then let go of the pressure
  • If you need more than one layer, apply glue again on top of previous layers (if two or more layers are needed)
  • Let dry at least 24 hours before handling – HDPE will feel firm but not brittle when it’s ready.

Epoxy Resin

Epoxy resin for HDPE is a very strong and durable glue.

It can be used to create new containers, repair broken ones or reinforce them in areas that are currently experiencing stress like high heat.

When using epoxy resins with HDPE make sure you use proper ventilation as they produce fumes that may irritate the respiratory system

How to glue HDPE together with Epoxy: Step By Step

Mix two parts of resin together (one part hardener) by adding each one into the other container while stirring it at the same time with your mixing stick. It will appear cloudy and lumpy when mixed properly but this won’t affect its function so don’t worry about making mistakes during this process if left unsupervised! Next add four parts of resin as you stir. Add the final two parts of resin while stirring, then pour it into your container with a funnel and let it set for an hour to cure before using or touching!

Glue is a great option if there is no access to bolts because many types do not require drilling holes first which saves time during installation. Glue can also provide strength where traditional fasteners would otherwise fail since they rely mostly on friction instead of sheer force from screws or nails that could strip out under stress over time. Plus, most glues work with hdpe pipe and are easy to use – you don’t need a lot of time or tools either which makes it great for those who want something they can do themselves without needing supervision.

There are some drawbacks with glue as well:

  • It is only useful when the surfaces being glued together have similar thicknesses since HDPE pipes may not work if one side has significantly more layers than the other;
  • Glues will sometimes take longer to dry so be prepared for them to set overnight instead of instantly like superglue does; also, glues that require 24 hours before handling won’t allow workers on site while glue dries because there’s always a chance it could get dirty in between steps which would ruin what was just glued together
  • Some adhesive types may not work well with HDPE because they don’t provide the strength needed – if this is the case, then it’s better to use glue sticks or hot glue instead and ensure that any gaps in between pipes are tightly sealed so there will be no leaks over time.

What glue works on HDPE?

When glueing HDPE, an epoxy resin is the best option. Epoxies can fill gaps and are flexible enough to handle temperature changes. It's also easy to apply with a syringe applicator or brush.

Will glue stick to HDPE?

The answer to this question is a qualified yes. The glue needs to penetrate the surface and then cure, so it's important that you have an even application of glue.

How do I know if my HDPE has been glued?

Check for bubbles or any rough patches on the plastic sheeting. Bubbles are caused by air pockets in the glue, which can happen if you apply the adhesive in a thick layer.

How do you speed up HDPE?

It's important to keep the material at a temperature above 60 degrees Fahrenheit. A warm environment will allow it to cure faster, but not too hot or cold and avoid prolonged exposure in direct sunlight.


Glue is a great substitute for traditional fasteners like screws or nails since it has similar strength when installed correctly but also doesn’t require drilling holes first which saves time during installation. There are, however, some drawbacks as well such as the need to wait overnight until drying and sometimes not being able to work on site while it sets.
