Review: Finished the trim - These add an extra touch to your trim project. Wish there were more buying options.
Review: Poor Quality, Poor Support - I ordered hundreds of dollars of InstaTrim for a large commercial project. It fell off. The company sent me some replacement with supposedly stronger adhesive. It was even worse. I have had 8-10 service calls to the site to fix issues. The company was not willing to stand behind its product or the quality. The owner told me he has never seen the product fall off like that and it was probably something at the job site that was to blame—- and I should just swap it out for a different product because he can’t help me. He did extend his sympathy so I guess that makes up for the hundreds of dollars in products costs, countless hours of time to reapply trim, damage to my company’s reputation, and lost revenue on future jobs.

## Features

- FINISH CORNERS - Add the perfect finishing touch with the NEW InstaTrim Inside Corner Caps! These innovative corners close the gaps of 90-degree inside corners to create a clean, finished look. Great for walls, windows, counters, flooring, and more, these trim pieces cover the corner gap between two pieces of InstaTrim flexible trim.
- EASY APPLICATION - Don't waste another afternoon on a frustrating DIY project with confusing instructions. InstaTrim has easy-to-follow, clear instructions that will make your next home improvement project a breeze. These corner and end pieces work perfectly with InstaTrim 1/2" flexible adhesive trim. Simply slide the ends of the InstaTrim strips between the “face” and the “tail” of the cap piece at the corner - that's it! Then, sit back and enjoy the professional, finished look.
- NO MESS, NO STRESS - Traditional caulking can be messy, even for people who have used the product before. InstaTrim caulk tape takes the mess and hassle out of caulking projects, while still providing great results.

### ⭐⭐⭐⭐⭐ Finished the trim

### ⭐ Poor Quality, Poor Support
*by N***Y on November 26, 2025*

I have had 8-10 service calls to the site to fix issues. The company was not willing to stand behind its product or the quality.

### ⭐⭐⭐ Needs caulk on back
*by M***C on February 8, 2024*

It should have a layer of caulk on the back to create a waterproof seal, like the caulk strips have. That would make it 5-star. I pulled some of the caulk off the leftover strip & used that - I couldn't justify buying a whole tube of caulk for a little dab
