Just tried this on the kitchen floor where there were gaps between the seams! I'm 72 and this is the easiest product to use, fills in gaps with a few taps of a rubber mallet and puff! The gap is closed! Now I need to do the full length boards and rearrange the furniture to complete the job! I asked the guy who installed the flooring and he said he had to take care of it as he didn't know of an easy way to fix it. So for a few bucks I can make it myself! I watched a video on YouTube and here is how I found this product and how to use it! Almost a miracle!
