If you’ve ever tackled a home improvement project, you know that caulking can be a real headache—it’s messy, it’s fickle, and it definitely isn’t a simple task for beginners. So, when I stumbled upon InstaTrim, a game-changing self-adhesive caulk substitute, I needed to test it out.
Why I Used InstaTrim Instead of Caulk
My staircase renovation was almost complete; however, there was one last detail bugging me—the gaps where the treads meet the risers and stringers on three sides. Normally, I would have used caulk, but let’s be honest, I didn’t feel like taping every single step. Fortunately, I had heard about InstaTrim (flexible caulk strips), so I reached out to the company to see if they’d be interested in working together—and they sent me some to try!
What Makes InstaTrim Different?
InstaTrim is a peel and stick trim that molds to surfaces using a putty adhesive, creating a seamless and tight seal. Unlike traditional caulk, there’s no mess, no odor, and no waiting around for it to dry. Plus, it’s completely removable, making it a great option for renters. Here’s what I loved about it:
- Mess-Free Application – No dripping, no smearing, and no cleanup required.
- Beginner-Friendly – If you can peel a sticker, you can apply InstaTrim.
- Flexible & Durable – It bends around corners and stays put.
- Made in the USA – High-quality and family-owned, which is always a plus.
- Non-Toxic & Safe – Perfect for any area of the home, including kitchens and bathrooms.

How To Install Instatrim
The process was ridiculously simple, and here’s what I did:
Time needed: 3 hours
How I Applied InstaTrim to My Stairs
-
Unroll The Spool and Let It Rest
-
Prep the Surface
Next, I made sure the stairs were clean and dry. Any dust or leftover debris can impact adhesion, so I wiped everything down thoroughly with Acetone. (FYI the instructions specifically say not to use cleaners with oil, wax or silicone)
-
Applying InstaTrim
I started by peeling back a small piece of the liner and applied it flush with the inside corner of the staircase. I used my hands at first to gently press the trim into place. I moved along peeling back the liner slowly. When I neared the end I used a screwdriver to make an indent on on the trim to show where to cut. Then I cut about 1/8″ inch past the indent.
-
Ensure a Tight Seal
I pressed the applicator tool firmly so the adhesive would spread and grab onto the entire inside corner. I used a flat head screwdriver to press the corners in firmly.
Tips for Installing Insta-Trim:
– Make sure it’s above 68 degrees when you’re working on this.
– Skip the cleaners that have oil, wax, or silicone in them.
– Be careful not to stretch the trim while applying it
– A hairdryer can help warm up the strip, making it easier to bend around curves.
– Don’t put it over any old caulk.
– Just like with traditional molding, you can join two pieces at a 45-degree angle.

I was honestly shocked at how professional the results looked. The gaps disappeared, and the edges of my staircase now have a clean, polished finish without the headache of caulk. And the best part? No waiting for anything to dry!
