We started using the Wilsonart 1730/1731 glue back in 2012. We had no problems with those projects. Last year we started receiving calls from clients about jobs from 2014 delaminating. Wilsonart and Wurth Wood are of course not accepting any blame. I have had other local shops contact me about the same issues in the same time frame. As of last week we are still having clients contact us about jobs from 2014. We have been in business since 1974 and have personally never seen anything like this happen to our products in all our years in business. Please contact me if you are also having issues at [email protected]. Other local shops are coming together on this.
