Product Reviews

I tried my best to fill in the crack before the top coat filler was applied, and hopefully it will do its job without causing too much trouble. I'm crossing my fingers that it won't come back into play anytime soon.

I've had the pleasure of using their product on multiple occasions, and I can confidently say that they're an absolute must-have for anyone who needs to fill gaps in their space.

It's not every day you come across a product that truly delivers when it comes to its purpose - this one does.

I've had my fair share of dealing with stubborn ceiling cracks, but this one took the cake. I thought I'd finally cracked under pressure and gouged out the plaster, thinking it was gone for good. But nope, the house is still having none of it. Instead, I ended up using scrim tape to cover up what little material remained.

I've heard that prepping the area before filling in can make all the difference, but I'm not sure if it's enough on its own. The process was tedious and labor-intensive, with a layer of dried plaster sticking to my hands like glue afterwards. And to make matters worse, the crack still shows up at times when the house is hottest or coldest.

I spent hours prepping and filling in just to get this one tiny crack sealed off, only for it to reopen months later as temperatures fluctuated. It's a sad state of affairs, but I suppose that's what happens when you're dealing with moisture-laden air and poor insulation.
