PVC Adhesive

Adiseal adhesive & sealant is a strong & flexible PVC adhesive as well as a great adhesive for other materials. It will stick PVC to wood, metal, concrete, plastic, tile, cable, polystyrene, masonry, glass & many other items. Adiseal can be used as an adhesive for PVC wall panels, PVC panel adhesive, adhesive for PVC cladding, adhesive for PVC trim, adhesive for PVC sheet as well as many other PVC items. The Adiglue product can also be used as a strong PVC glue.

Which PVC adhesive?

There are many different adhesives & glues available that can be used to stick PVC but to achieve a strong & long lasting bond, the correct PVC adhesive or PVC glue needs to be used.


Why Adiseal is great adhesive for PVC

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

PVC adhesive. Strongest in independent adhesive strength test.

  • Adiseal is the record breaking strongest adhesive & sealant. It proved it’s the best in an independent adhesive strength test by Ultimate Handyman.
  • Adiseal stays permanently flexible so it will absorb any vibration and allow any items to expand & contract without the construction adhesive becoming weak.
  • Adiseal is waterproof so it is also suitable for use outside. It also seals underwater & glues underwater.
  • Priming the material should not be required as long as the surface is clean of any dust, grease, paint or any other dirt.
  • It does not stain or bleed into stone or masonry.
  • Adiseal has very high gap fill properties.
  • Has high initial grab meaning temporary supports may not be required while the construction adhesive cures. Adiseal Hi-Grab has even higher grab than the standard product, see below for details.
  • With Adiseal, the stone does not require sealing prior to applying Adiseal.


In the independent adhesive strength test by Ultimate Handyman, Adiseal was over 3 times stronger than the nearest competitor. The test on Adiseal was forced to be stopped as the screws holding the test rig down started to rip out.

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 very useful when trying to bond heavy items to a vertical surface where the item is likely to slide down the surface without temporary supports to hold it until the adhesive has cured. With the Hi-Grab construction adhesive, the adhesive grabs straight away, eliminating the need for temporary supports even in more heavy applications.

Adiseal Hi-Grab also has even higher gap fill than the standard Adiseal adhesive & sealant. Due to Adiseal Hi-Grab adhesive having a thicker consistency, a lot higher force is required to push the item to the surface you are bonding it to. For this reason in certain applications the standard Adiseal adhesive & sealant is the better option to go for as you can reduce the gap between the 2 items being bonded.

Problems with epoxy adhesives

There are several problems with using epoxy adhesives on PVC. Listed below are the main problems of epoxy adhesives.

  • Although epoxy adhesives might initially bond the item to a PVC surface, epoxy adhesives are not flexible meaning the bond will become weaker over time. Air temperature & moisture changes cause items to expand & contract putting extra forces on an adhesive. If the adhesive is not flexible it will become weak & brittle, then eventually break.
  • Epoxy adhesives also come in 2 separate components which require mixing. To achieve optimum epoxy adhesive properties, the 2 components need to be the correct ratio therefore require careful measuring. They also need to be mixed thoroughly together. If these 2 are not done then the optimum properties of the epoxy may not be achieved.
  • Epoxy adhesives have lower initial grab than Adiseal, meaning temporary supports will usually be required whilst the epoxy adhesive cures. This increases time & money with extra labour cost.


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.

  • The main problem with mastic adhesive is that the bond is weak in the 1st place. A mastic adhesive might be suitable at sticking light items indoors but will fail at more heavy duty applications.
  • Another problem with mastic adhesives are they are not waterproof. This means they are not suitable for use where there will be water like bathrooms, kitchens or outdoors.
  • Just like epoxy, mastic adhesives are not flexible meaning the already weak bond will become weaker over time.
  • The initial grab of the mastic adhesive is also low meaning temporary supports will be required, increasing time & labour cost.


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 have low initial grab meaning temporary supports will be required until the adhesive has cured.
  • Contact adhesives also has low gap fill meaning if there is a gap in certain places between the 2 surfaces of the items being bonded, the contact adhesive will not stretch between the 2 surfaces. This will create a much weaker bond as only in a few places where the surfaces are very close together will the adhesive successfully bond.


Problems with using glue on PVC

Glues are generally suitable at sticking small items to smooth surfaces but not for more heavy duty applications like sticking PVC cladding to walls. For more heavy duty applications, a construction adhesive like Adiseal will be required. Glues have lower gap fill, initial grab, bond strength, flexibility & other problems compared to Adiseal adhesive & sealant when trying to stick items to PVC.

PVC items

There are many different PVC items Adiseal will stick & provide a strong bond. Some examples include:

  • PVC wall panels
  • Cladding
  • Panels
  • Trim
  • Sheet
  • Trunking
  • Conduit


Adhesive for PVC wall panels

Adiseal is a strong, waterproof & flexible adhesive for PVC wall panels. It will stick PVC wall panels to different wall surfaces including brick, concrete, plaster, wood, stone, tile and other wall surfaces.

It is recommended to apply the adhesive for wall panels in thin vertical strips where there is a chance of water running behind. This allows any water to run down instead of building on top of the adhesive. In cold temperatures, this water can freeze and expand. This will put additional strain on the adhesive.

It is also recommended to clean both surfaces before applying the adhesive for PVC wall panels. Brushing the wall with a fine brush like a painting brush will help remove fine dust. Priming of the wall should not be required when using Adiseal adhesive & sealant.

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 use any primer on the concrete block before applying the adhesive.

Adhesive for PVC cladding

Just like using Adiseal as an adhesive for PVC wall panels, Adiseal can also be used as an adhesive for PVC cladding. It will provide a strong, waterproof & flexible PVC cladding bond.

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 & construction sealant to stick the same metal handle to concrete or stone.

We have also stuck some bricks together & also brick to MDF with Adiglue to demonstrate what it is capable of. Sealing with Adiglue Activator was required first prior to applying the glue.
