Does Liquid Nails Work on Plastic? Find Out Here

When it comes to adhesive choices for various materials, Liquid Nails stands out for its strength and durability. But what about its effectiveness on plastic? In this blog post, we will explore the capabilities of Liquid Nails when used on plastic surfaces, along with some tips for achieving the best results.

Does Liquid Nails Work on Plastic

Yes, Liquid Nails works on almost all types of plastic, except for polypropylene and polyethylene. These two types of plastic are rare and not commonly used in construction or household materials that you would typically be using Liquid Nails for.

What is Liquid Nails: A Versatile Adhesive

Liquid Nails is a trusted brand of adhesive that offers a range of products for different materials, including plastic, metal, concrete, wood, fabric, and foam. Known for its high strength, durability, and ease of use, Liquid Nails has become a go-to choice for many construction and DIY projects.

It presents a more versatile option compared to polyurethane adhesives, drying relatively fast and offering a strong bond.

Types of Liquid Nails

There are two types of Liquid Nails: solvent-based and water-based. Solvent-based has a stronger bond but is more toxic and flammable, while water-based is less toxic and flammable but has a weaker bond.

Ideal Conditions and Surface Preparation

To ensure the success of Liquid Nails on plastic, proper conditions must be met. The surfaces to be bonded should be clean, dry, and free from dust.

Additionally, it is crucial to use the right type of Liquid Nails specifically designed for plastic. Not all Liquid Nails products work effectively on plastic, as some are formulated for other materials such as particle boards or sub-floors.

Scuffing the surface of both the plastic and the material to be bonded is recommended to enhance the adhesive’s grip. This technique creates more pores for the glue to adhere to, promoting a stronger bond. Remember, Liquid Nails has difficulty sticking to smooth, non-porous surfaces, so roughening the surface is essential.

Types of Plastic Compatible with Liquid Nails


Liquid Nails is compatible with most types of plastic, except for polypropylene (PP) and polyethylene (PE). These two types of plastic have low surface energy, preventing Liquid Nails from drying and bonding effectively.

However, it is rare to find construction or household materials made solely from PP or PE, making Liquid Nails a suitable choice for a wide range of plastic applications.

How Long Does Liquid Nails Take to Dry on Plastic?

Liquid Nails dries slowly on plastic due to its non-porous nature, requiring more time for the adhesive to dry and reach its maximum strength.

While the surface may appear dry, it can take up to 24 hours for the adhesive to fully dry and up to 7 days to cure to its full strength. It is important to be patient and allow sufficient time for the adhesive to work its magic.

Tips for Using Liquid Nails on Plastic

To achieve the best results when using Liquid Nails on plastic, follow these steps:

  1. Choose the right type of Liquid Nails specifically formulated for plastic, such as Heavy Duty, Fuze It, or Extreme adhesives. The All Purpose clear adhesive in a 2.5-ounce squeezable tube also works well for smaller plastic projects.
  2. Use a caulk gun to apply the adhesive evenly. Scuff the surface of the plastic with sandpaper or score it with a utility knife. For larger, heavier pieces, consider drilling small holes in the bonding surfaces to allow the adhesive to penetrate and create a stronger hold.
  3. Apply the Liquid Nails around the edges and in a zigzag pattern on the inside areas, ensuring even thickness. Avoid applying the adhesive everywhere, as it needs room to spread when the surfaces are pressed together.
  4. Press the two surfaces together firmly and wipe off any excess adhesive that seeps out from the edges.

Storing Liquid Nails After Use

To prolong the shelf life of Liquid Nails, it is essential to store the adhesive properly. If you haven’t used the entire tube, consider the following tips:

  • For smaller 2.5-ounce tubes, screw the cap back on tightly, ensuring no adhesive remains on the threads.
  • In the case of a 9-ounce tube, seal the cut tip by inserting a screw, using painter’s tape tightly, or applying a nail.

Benefits of Liquid Nails on Plastic

Using Liquid Nails for plastic bonding comes with a host of benefits:

  1. Superior strength and durability for lasting bonds.
  2. Weather and water resistance, perfect for outdoor applications.
  3. Safe and odor-free formula without VOCs.
  4. Reusable with proper storage techniques.
  5. Wide range of products for various materials and applications.
