Polystyrene Adhesive: Adiseal Glue for Polystyrene

To glue polystyrene, using Adiseal polystyrene adhesive will provide a high-strength and durable bond. It has many advantages over other adhesives when it comes to sticking polystyrene including staying flexible and waterproof. Adiseal has also been shown to be the strongest adhesive in an independent adhesive strength test.

Benefits of Adiseal

Other benefits of Adiseal include:

Beneficial properties

As well as Adiseal being the strongest adhesive available, it’s also very safe at the same time. It stays permanently flexible & is waterproof as well. Adiseal also has high initial grab eliminating the need to put temporary supports for most applications. For even higher initial grab, use the Adiseal Hi-Grab product.

Tip: When using waterproof adhesive on a vertical wall, apply thin vertical strips. This lets water run down between the adhesive, preventing buildup. In cold temperatures, water can turn to ice, applying extra pressure and weakening the bond.

Flexible adhesive

One issue with a non-flexible adhesive is its tendency to become brittle and weak over time. Adiseal’s flexibility allows it to absorb vibrations and adapt to temperature and moisture changes. This makes Adiseal not only the strongest adhesive but also provides a durable, long-lasting bond.

How to glue polystyrene

How to glue polystyrene

  1. Prepare the Surface

    Ensure that the surface where you will be attaching the polystyrene is clean, dry, and free of any dust, grease, or debris. Use a suitable and safe cleaner to remove any residues.

  2. Apply the Adhesive

    Apply the adhesive to the back of the polystyrene and ensure even coverage. Be cautious not to use too much adhesive, as excess adhesive may squeeze out and become visible around the edges of the polystyrene.

  3. Position the polystyrene

    Carefully place the polystyrene onto the prepared surface, aligning it with the desired position. Press firmly, applying even pressure across the entire surface of the polystyrene to ensure good contact between the adhesive and the surface.

  4. Support the polystyrene

    If necessary, use temporary supports, such as adhesive tape or brackets, to hold the polystyrene in place while the adhesive cures.

  5. Remove Excess Adhesive

    Wipe away any excess adhesive that may have squeezed out around the edges of the polystyrene using a clean cloth.

  6. Allow Proper Curing Time

    Avoid disturbing or putting stress on the polystyrene during the recommended curing time. This allows the adhesive to fully set and ensures a strong bond.

Tip: To store Adiseal once opened, leave about 1cm worth of product out of the nozzle and store the tube upright in a cool dry place. Adiseal requires moisture for it to cure. The exposed part out of the nozzle will cure creating a cap. To re-use Adiseal, pull the cured part out or cut the nozzle until the uncured part is reached.

Adhesive for polystyrene insulation

Polystyrene is used to make several different construction and building materials including polystyrene insulation, polystyrene tile, coving and filler. Adiseal is a great adhesive for polystyrene insulation as well gluing polystyrene tiles to a ceiling, sticking polystyrene coving to a wall and many other applications.

Adiseal adhesive & sealant vs Adiseal Hi-Grab

It is also possible to stick polystyrene with Adiseal Hi-Grab but we recommend using the Adiseal adhesive & sealant. Adiseal Hi-Grab is a thick product that requires a lot higher force to push two materials close together. It provides a higher initial grab compared to the Adiseal adhesive & sealant but since polystyrene is a very light material, this extra high initial grab should not be required.

Where to buy polystyrene adhesive
