The product was very easy to use. However for us the fix was only a temporary one, as after a few days or so the creaking and cracking has started again. I can only assume that this is because the product has now dried and is no longer lubricating in between the floor boards.
This stuff has really helped. Loud squeaks are very soft now and many soft ones are completely gone. The creaking was driving up the wall and StopCreak has provided me with sanity. Definitely worth it to try before spending a fortune replacing floors. It is worth every ounce of a 5 star customer review and more! Cheers Greg
You saved us a fortune!
