PVC Adhesive

(Last Updated On: 2 June 2023)

PVC Adhesive

Adiseal is a highly versatile adhesive that has a range of applications, including as a strong and flexible PVC adhesive. Adiseal is capable of bonding PVC to a variety of surfaces including wood, metal, concrete, plastic, tile, cable, polystyrene, masonry, glass, marble, and many other materials.

In addition to being a great adhesive for PVC wall panels, adhesive for PVC cladding, PVC trim, and PVC sheet, Adiseal can also be used as a PVC panel adhesive, as well as for many other PVC items. The Adiglue product, which is also available, can be used as a strong PVC glue. In this article we will also look at how to use a PVC adhesive.

Which PVC adhesive?

To achieve a strong and long-lasting bond when sticking PVC items, it’s important to select the appropriate adhesive or PVC glue. With numerous adhesives and glues available, it’s essential to choose the right one for the specific PVC application. For instance, if you plan to stick PVC cladding outside, you need to use a PVC cladding adhesive that can withstand various weather conditions, including temperature changes, wind, and rain. This will ensure that the bond between the PVC cladding and the surface remains strong and secure over time.

Why Adiseal is a great adhesive for PVC

There are many reasons why Adiseal adhesive and sealant is a great adhesive for PVC.

PVC adhesive. Strongest in independent adhesive strength test.

Adiseal is the record-breaking, strongest adhesive and sealant that has shown to be the strongest construction adhesive in independent strength tests conducted by Ultimate Handyman. It can bond PVC and other materials with extremely high strength.

One of the key advantages of Adiseal is its permanent flexibility, allowing it to absorb any vibration and accommodate the expansion and contraction of items without losing its strength. This feature is especially useful when sticking PVC items outdoors, such as PVC cladding.
Being waterproof, Adiseal is also suitable for use outside, and it can seal in the wet as well as underwater. Additionally, priming the material is not necessary as long as the surface is clean and free from any dirt, grease, or paint.

Adiseal also has high gap fill properties, ensuring that even irregular surfaces can be bonded securely without the need for temporary supports. The Adiseal Hi-Grab version has even higher initial grab than the standard product, making it possible to avoid using temporary supports while the adhesive cures.
What’s more, Adiseal will not stain or bleed into stone or masonry when used to stick PVC items to these materials. And unlike other adhesives, Adiseal does not require porous materials like stone to be sealed before application, making it a versatile solution for a variety of applications.

Adiseal Strength Test

In the independent adhesive strength test by Ultimate Handyman, Adiseal demonstrated remarkable strength, outperforming its closest competitor by over three times.

During the test, the strength of Adiseal was so impressive that the screws holding the test rig in place began to rip out, forcing the test to be stopped. Even at over 3123 psi, Adiseal did not break or give way, demonstrating its unbeatable strength and durability.

Adiseal Adhesive & Sealant vs Adiseal Hi-Grab

Adiseal adhesive & sealant has high initial grab but for even more grab use the Adiseal Hi-Grab adhesive. The final bond strength of both construction adhesives is similar.

Adiseal Hi-Grab is particularly beneficial when bonding heavy items to a vertical surface, where they may otherwise slide down before the adhesive cures. Thanks to its superior initial grip, this construction adhesive eliminates the need for temporary supports, even in more heavy duty applications.

Additionally, Adiseal Hi-Grab boasts a higher gap fill capacity than the standard Adiseal adhesive & sealant, owing to its thicker consistency. While this attribute can make it more challenging to apply, it results in a stronger bond overall. In certain circumstances, however, the standard Adiseal adhesive & sealant may be the preferred option as the gap between the two items can be reduced when pushing them together, leading to a more robust bond.

How to use a PVC adhesive

How to use PVC adhesive

  1. Ensure even surfaces.

    Make sure both surfaces are even to avoid large gaps between the items when placed together.

  2. Clean surfaces.

    Thoroughly clean both the PVC surface and the other surface. Remove any oil, grease, tar, dust, or any other dirt. Use a fine brush like a painting brush to remove dust.

  3. Non porous materials.

    PVC adhesives like Adiseal require moisture for the adhesive to cure. If at least 1 material is porous, then the moisture in the air is used. If both materials are non porous then it is recommended to spray a little bit of water mist on the surface of the material before applying the adhesive.

  4. Apply adhesive.

    Apply the adhesive thinly, trying to cover as much surface area as possible.

  5. Push items together.

    Firmly push both items together, sliding them side to side slightly while pushing to reduce the gap between the two materials.

  6. Use temporary supports only if needed.

    Temporary supports are not usually required. If the item starts to slide or pull away, use temporary supports to hold the item in place until the PVC adhesive cures.

Problems with epoxy adhesives

There are several problems with using epoxy adhesives on PVC. Listed below are the main problems of epoxy adhesives when trying to stick PVC or other materials.

  • Epoxy adhesives may appear to bond PVC initially, but they are not flexible, making the bond weaker over time. This is because air temperature and moisture changes cause the items to expand and contract, which puts additional stress on the adhesive. If the adhesive is not flexible, it can become brittle and eventually break.
  • Epoxy adhesives come in two separate components that require precise measuring and thorough mixing to achieve the desired properties. Failure to do so can result in suboptimal bonding strength.
  • Epoxy adhesives have lower initial grab than Adiseal, which means that temporary supports are often required while the adhesive cures, resulting in additional labor costs.

Problems with mastic adhesives

Just like epoxy, mastic adhesives also have many problems when being used as an adhesive on PVC. Listed below are the main problems of mastic adhesives.

  • Mastic adhesives have weak bonding strength, making them unsuitable for heavy-duty applications. They are only appropriate for light items indoors.
  • Mastic adhesives are not waterproof, which makes them unsuitable for use in damp environments such as bathrooms, kitchens, or outdoors.
  • Mastic adhesives are not flexible, which can cause the bond to weaken over time.
  • Mastic adhesives have low initial grab, requiring temporary supports during the curing process, which adds to labor costs.

Problems with contact adhesives

Contact adhesives may be suitable in sticking light sheets to a surface but won’t not suitable for more heavy duty applications. There are a number of problems with contact adhesives.

  • Contact adhesives are not suitable for heavy-duty applications. They have low initial grab, which means that temporary supports are necessary during the curing process.
  • Contact adhesives have low gap fill, which means that if there are gaps between the two surfaces being bonded, the adhesive will not be able to fill them completely, resulting in a weaker bond.

Problems with using glue on PVC

Glues are generally suitable for small items on smooth surfaces, but not for heavy-duty applications like attaching PVC cladding to walls. Adiseal adhesive & sealant is a better choice for such applications because it has higher gap fill, initial grab, bond strength, and flexibility.

To glue PVC items that are not heady duty, Adiglue is the more suitable product.

PVC items

Adiseal can effectively bond and provide a strong hold to a wide range of PVC items. Here are some examples:

  • PVC wall panels
  • Cladding
  • Panels
  • Trim
  • Sheet
  • Trunking
  • Conduit
  • Moldings
  • Skirting
  • Electrical boxes

The versatility of Adiseal adhesive & sealant makes it a reliable option for bonding various types of PVC items, providing a long-lasting and durable hold.


Adiseal is available in the following colours:

It can also be manufactured in any RAL colour. Please contact us for more details.

Adhesive for PVC wall panels

Adiseal is an excellent adhesive for PVC wall panels due to its strength, waterproof and flexible adhesive properties. It can bond PVC wall panels to various surfaces such as brick, concrete, plaster, wood, stone, tile, marble, and more.

To ensure the best bond, it is recommended to apply the adhesive in thin vertical strips, especially in areas where water can run behind the wall panel. This prevents water from building up on top of the adhesive, which can freeze and expand in cold temperatures, putting additional pressure on the bond.

Before applying Adiseal, it’s essential to clean both surfaces thoroughly. Using a fine brush, such as a painting brush, will help remove fine dust from the wall surface. Unlike other adhesives, Adiseal does not require primer on the wall surface before application.

On the demonstration concrete block below, we have stuck many different items to it with Adiseal adhesive & sealant. One of the items stuck to the concrete is PVC trunking. This was done by brushing the concrete first with a paint brush to remove fine dust. We did not need to use any primer on the concrete block before applying the adhesive.

Adhesive for PVC cladding

Adiseal is an ideal adhesive for PVC cladding, whether it is for internal or external use. It has excellent adhesion properties that make it perfect for bonding PVC cladding to different surfaces, including brick, concrete, plaster, wood, stone, tile, and other wall surfaces. Its waterproof and flexible features also make it an ideal choice for outdoor use, where it can withstand different weather changes.

PVC glue

It is also possible to glue PVC using our Adiglue. Although Adiglue is less brittle than super glues, it is still not as flexible or strong as Adiseal construction adhesive & construction sealant.

In the example below we have glued a metal handle to a heavy concrete slab with the Adiglue glue. The concrete required sealing first with Adiglue Activator so that it does not soak up the Adiglue. Sealing is not required when using Adiseal construction adhesive & sealant to stick the same metal handle to concrete or stone.

To demonstrate what Adiglue is capable of, we have also stuck some bricks together and also brick to MDF with Adiglue. Sealing with Adiglue Activator was required first prior to applying the glue as the materials were porous. This is not required on non porous materials.
