We Make Trim Easy and Seamless

As a former home builder, Greg Amundson discovered a gap in the building industry. In 2008, when the housing market crashed, he got the idea to solve a problem for many homeowners. An easy solution to DIY projects that is mess-free and looks great every time you use it. After a lot of tinkering, testing, and making improvements, InstaTrim was born.

Greg and Betsy Amundson work together and serve together, donating their time and product to Operation Honor – Veteran Proud, a non-profit organization that hires veterans to make hand-crafted burial and retirement flag cases. InstaTrim provides the perfect seal for the cases.

We're proud to say that our trim strips are a healthier alternative to caulk. Meeting ASTM 4236 for non-toxicity, InstaTrim does not contain toxic chemicals and there are no smelly fumes. These strips don't require cure time and the adhesive never dries out. If you have some remaining, pull it out of the garage for your next project.

Frequently asked questions

How are InstaTrim products different from all the other caulk strips on the market?

InstaTrim, The Original Flexible Trim™, with our Patented “wing” design and a proprietary high-performance adhesive, InstaTrim products will conform and seal to almost any application surface including ceramic tile, laminate, solid surfaces, wood, metal and much more.

Caulk strips you may have seen on the market are mostly made in China, are bulky, unattractive and use sub-par two-sided tape for adhesive. These products have the reputation of being cheap-looking with adhesive that does not last. InstaTrim products are easy to use, mess-free, last for years and will leave your project looking clean and professional, every time.

Custom and personalized orders

There are currently two widths of InstaTrim products available. The adhesive on the back covers the middle part of the strip. As you push the InstaTrim into the corner, the adhesive grabs and spreads onto the surface. The adhesive is roughly half the width of the strip.

Custom and personalized orders

There are a few factors that could be causing the adhesive to fail. Most likely, there is old silicone caulk or residue from silicone on the surface. Silicone is unique in that no other adhesive will stick to it, that’s why it is very important that all silicone be removed 100% for successful adhesion of InstaTrim strips. The good news is, that silicone and silicone residue can be removed. Silicone removal instructions can be found on our downloadable Instructions PDF.

If your surface has silicone on it, remove as much as you can with a razor blade. Apply a silicone remover product to help dissolve the old silicone. We have had success with McKanica Products, WD40 and acetone. It will also help to scrub with a scrubby sponge.

Custom and personalized orders

Yes, you can! For best results and ease of use, we recommend installing the trim strips when the air temperature is around 65°F to 70°F. Once installed, it will remain attached in any temperature. Our products are manufactured in and distributed from Minnesota where our testing involves exterior surfaces in all weather extremes.

Custom and personalized orders

InstaTrim can be easily removed at any time. Use a putty knife to gently lift the end of the trim strip, grasp the end and slowly pull it backward and away from the surface. Some adhesive will remain, however you can remove most of it with a razor blade or your fingers. Our adhesive sticks to itself very well, so you can ball up a small amount and rub it on the remaining bits to pull the smaller pieces of adhesive from the surface. Follow up with acetone and a soft cloth to dissolve any remaining residue.
