What Do You Stick uPVC On With?

When it comes to installing uPVC trims, selecting the right adhesive is crucial for a secure and long-lasting fit. While there are various options available, three common methods are often used in the installation process.



  1. Super Glue with Activator

Superglue is a widely preferred choice for installing uPVC trims due to its strong bonding capabilities. Many commercial super glues are formulated with an activator that accelerates the drying time of the adhesive. Here's how to use it effectively:


- Apply the superglue to the rear edge of the uPVC trim.

- Position the trim in the desired location.

- Hold the trim securely in place for a few seconds, allowing the activator to work its magic.


This method offers a quick and secure bond, making it a favourite among installers. It's particularly effective for trims that require a strong, reliable connection.



  1. Low Modulus Silicone

Another option for installing uPVC trims is using low-modulus silicone. While silicone can provide a secure hold to bring some more life to your windows or other features in your house, there are some important considerations to keep in mind:


- Silicone may take longer to set compared to superglue.

- When using silicone for trims in overhead positions (such as the top of a window reveal), extra support may be needed until the silicone has fully cured.


Low-modulus silicone can be a good choice when you require flexibility or if you're working with uPVC trims in areas prone to movement. However, it's essential to account for the longer drying time and support requirements.



  1. Grab Adhesive

While grab adhesive is an option for uPVC trim installation, it may not be the preferred method for many installers. Here's why:


- Grab adhesive can be messy and challenging to control during application.

- It may not offer the same rapid bonding as super glue with activator.


Due to the messiness and unpredictability of grab adhesive, many professionals tend to lean towards the super glue method for uPVC trim installation.



In conclusion, when deciding what to stick uPVC trims with, consider the specific requirements of your project. Super Glue with activator is a popular choice for its reliability and quick bonding, while low-modulus silicone can be suitable for situations that require flexibility. While grab adhesive is an option, it may not be the cleanest or most efficient method in most cases. Ultimately, the choice of adhesive should align with your project's needs, ensuring a secure and durable installation of uPVC trims.
