When it comes to installing weatherstripping, many individuals tend to choose a quick and straightforward approach, often applying a thick bead of adhesive directly onto the metal surface before positioning the weatherstrip atop it. However, this method frequently results in excess adhesive oozing out from the sides and the weatherstrip shifting out of alignment, along with a prolonged drying time. Although this may appear like a simplistic technique, it is not an effective one. At Steele, we are committed to teaching DIYers how to do the job right the first time. Following this gluing technique will get you the best results, time after time.

What You’ll Need

Before we show you the best technique for gluing, it’s important to have the right adhesive for the job.

3M Super Weatherstrip Adhesive is the perfect choice! This product was designed specifically to bond weatherstripping to metal, creating a waterproof and airtight seal. It is ideal for gluing rubber seals and gaskets onto the vehicle body around doors, trunks, T-tops, and windows.

Other supplies to make the job easier:

• Popsicle stick
• New weatherstripping
• Gloves

It is extremely important that you prep the surface before gluing! This means removing all the old weatherstripping, leftover adhesive residue, and any dirt or debris. This step cannot be skipped! The adhesive bond will be compromised if applied to a dirty surface.

Proper Gluing Technique

Begin by applying a thin, even bead of adhesive directly onto the metal surface. Remember, a little goes a long way! Use a popsicle stick to spread the adhesive into a uniform thin film and allow it to sit for a few minutes to tack up.

Next, you’ll repeat that same process on the weatherstripping. Apply a thin bead down the gluing side of the new rubber seal and spread it into a thin film with the popsicle stick. Let that sit for a few minutes to tack up.

Once both surfaces are tacky, apply a final thin bead of adhesive to one of the surfaces before pressing the weatherstrip in place. Ensure to press firmly across the entire length of the weatherstrip to guarantee complete contact with the metal surface. This technique prevents excess adhesive from oozing out the sides and significantly reduces drying time. In most cases, the bond is likely to be almost instantaneous, ensuring a reliable and efficient application.

Allow 24 hours for the adhesive to fully cure. When gluing weatherstrip on a door, trunk, RV slide out, or any area where the seal will be compressed, wait the full 24 hours before shutting the door, closing the slide out, etc.

Peel-N-Stick

Our Peel-N-Stick products are designed for an easy, mess-free installation process. The adhesive backing is exceptionally sticky and begins forming a bond immediately after it’s applied, making it quite challenging to reposition after pressed in place. To ensure precise placement, perform a test fit with the new weatherstripping before removing the protective backing.

The surface prep is just as crucial when applying Peel-N-Stick weatherstrip. This step cannot be skipped, or the integrity of the adhesion will be compromised.

Once you’ve performed a test fit and know exactly where you’ll be installing the new seal, simply peel off the protective backing and press into place.

Allow 24 hours for the adhesive to fully cure and the job is done!

Installation Tips

Tip #1: To control the application of the glue, dispense small amounts of the adhesive onto a piece of cardboard and utilize a popsicle stick for even distribution. This method guarantees precise application, ensuring that the adhesive is only placed in the desired areas.

Tip #2: For projects with a large surface area, like a trunk or RV slide out, install only 2-3 feet at a time using this gluing method. This eliminates the risk of the adhesive drying too rapidly, allowing for a more controlled and meticulous installation.
