Description

As a former home builder, Greg Amundson discovered a gap in the building industry. More than a decade ago, he had an idea to solve a problem for homeowners and contractors – an easy-to-use alternative to caulk that is mess-free and looks great every time. After a lot of testing and tinkering in the family garage, InstaTrim was born. InstaTrim has a Patented “wing” design and a proprietary high-performance adhesive that allows it to stick to almost any surface! InstaTrim is the easy-to-apply, mess-free caulk substitute. It can be used for a variety of household projects to achieve professional results without the hassle InstaTrim is water-resistant- The wings are designed to push back against the surface beyond the adhesive creating an extra layer of protection from moisture, dirt and air. Our products are flexible enough to smoothly go around wide curves. If the curve is tight, InstaTrim may not be right for the job. These strips don't require cure time and the adhesive never dries out. We recommend installing when the air temp is about 65°F to 70°F. Yes! We recommend using latex paint for InstaTrim to get an exact match Yes! InstaTrim can be installed by beginners. Follow the included instructions and see your home improvement in minutes! Make sure the surface is prepped and clear of any silicone Yes, you can! Our products are manufactured in and distributed from Minnesota where our testing involves exterior surfaces in all weather extremes. For best results, we recommend installing the trim strips when the air temperature is around 65°F to 70°F.

    • Clean and neat installation
Size: 3/4 in x 10 ft Color: White
Review Image by jeff
Easy install. I first steam cleaned and allowed to dry for a few days. Floors are radiant heat. Just before install I cleaned toilet base and floor with Acetone and allowed to dry. I purchased the factory tool to push in the edging tight and uniformly. I have not tugged on edge or end and final opinion will be amended and noted if needed over time. The adhesive has a bit of gooey feel to it and seemed extremely sticky which is initially comforting. With the heated floors this should be an ideal installation. Remains to be seen! I really like the tidy look over the initial paintable caulk I applied to seal the toilet to code. This application was purely decoration . I am hoping the underlying caulk will allow for better adhesion over the long term. This is a commercial application and the floor it abuts is mopped every other day. We shall see. 2 months report: Still perfect and tight. No change. A+++ ... show more

    • Nice clean edges!

This product served as the perfect finishing touch to my DIY stair project. It Adheres to any 90 degree space with a bead of old school blue tack. It's tack, so you really need to get some friction going to meld it into the corners. If it gets hairy/dusty/wet before it's stuck into its final destination, you may need to use additional reinforcement for secure adhesion. But if you do it right at the outset, it stays put. The first set of stairs I did leads to the garage and is high traffic and it is still in place after 5 months. I imagine salt and mud in the winter might give it some trouble but, again, nothing some caulk or silicon couldn't resolve. The tack make it so clean and easy! Also, it is very easy to clean because it is vinyl. It prevents all those tiny pieces of stuff from getting into the cracks between the wall and stairs. Love it! ... show more

This was much easier to work with than caulking, and you end up with a perfect finish. The gooey adhesive reminds me of plumbers putty. I ordered the ivory to better blend with my solid wood bathroom countertop and the ivory mother of pearl wall. It is fairly easy to cut with good scissors, and was Abe to cut 45⁰ angles for the corners. My only gripe is the raw ends could really use some type of finishing cap. I ended using biscuit caulking to encase the ends and make them blend better. So I didn't actually escape having to use caulking. I plan on ordering more to use between the flooring and shower pan instead of 1/4 round that catches dust and water. Hopefully this was helpful, Thank you! ... show more

    • Doesn’t stick quartz to quartz.
Size: 1/2 in x 10 ft Color: Ivory
Mixed review. Stuck, worked and looked great on our kitchen counter. Quartz to backsplash tile. However, it did not stick at all to the bathroom counter. Quartz to quartz. We are in a new build so we are experiencing some settling. Very happy with kitchen but very disappointed with bathroom.

I’ve never been a fan of messy caulk jobs - esp when at least one of the surfaces is really nice tile or stone. So after reading a story about this product & the Twin Cities company that makes it, I ordered several rolls right away. It has now been less than 1 year since I installed it. Got a ton of compliments early on & several folks even asked where I bought it. I have a strong construction background so I made sure to read the directions closely in order to determine how to prepare the surfaces & much pressure to apply when “sticking” the caulk backer into the gap between the 2 surfaces. I also knew that if I stretched it too much when applying pressure the joints would most likely separate. So I didn’t stretch the product at all. The joints around the 3 sides of my corner whirlpool & vanity sink top that meet the mosaic stone backsplashes looked awesome! But even though our basement is climate controlled - in-floor radiant heat, dehumidifier, humidifier & air quality monitor too - this product looks like crap just 9-10 months later. All the corner joints have pulled apart & there are several spots where it is pulling away from the backsplashes. And where I used it to fill a gap between a painted beam & a painted tongue & groove ceiling, it’s falling off - even though I’ve reapplied pressure several times after seeing it coming loose. So it was a complete waste of money & now I have to remove it & clean the surfaces all over again so I can use a good silicone sanded caulk that matches the grout I used for the mosaic stone. Which is exactly what I wanted to avoid & why I bought this product! What a major disappointment! ... show more

    • Potentially useful product for dry applications, let down by some quality control issues.
Size: 3/4 in x 50 ft Color: White
It got the job done, but my biggest gripe with this product is that it arrived with black marks along the entire length of the product. You get a note in the box from the seller asking you to try the small sample piece first, and not to unravel the main reel if you plan to return the product. Problem is you don’t realize until you start unraveling the full product that literally the entire length of it is sullied with black marks and they don’t come off easily. It’s not just dust from the factory you can wipe off with a cloth. After installing the trim, I completely decimated several packs of Magic Erasers to get all the black marks off and achieve a clean white appearance. It’s a shame because I would have liked to have used this product for another room as well but I can’t justify paying $60 for another reel of product with such low quality control that I have to spend just as much time cleaning it as installing it. I was looking for a solution in place of having to install quarter round molding after having my floors sanded. To close up the gaps and hide the edges, it could potentially work well save for the problems described. I would say it takes a couple of goes to learn exactly how to lay it, you need to stretch it a little as you stick it down to get a smooth flush result. It’s not foolproof but also not too difficult. I definitely would not use it for applications near water because the top and bottom of the product will not be adhered to the surface. The adhesive section runs through the middle where it creates the right angle behind the product, and the top and the bottom of the trim then just sit on the surface. Should be good enough to keep dust and debris out, but I can’t see it keeping water out too well. If moisture gets trapped behind the trim then I would expect it to become a bacterial breeding ground behind there. ... show more
