laminate panels

When a customer asks for help with de-laminating panels, we do not suggest screwing down the HPL, or attempting to field repair with contact adhesive.  

We highly recommend the customer use our IDC Submission Form Quote for Replacement Panels and to send in photos. We need to find out the reason why the panels are de-laminating. Most often it's improper maintenance (mostly over wetting the floor with harsh chemicals in the water) but it can also be because of fluctuations in heat and humidity. Woodcore panels are especially susceptible to this because the panels are made by taking a large piece of sheet metal and slitting the corners, then bending up the sides and dropping in the 1" thick piece of pressboard. The slits on the corners are not water tight and through time water can migrate into the pressboard causing it to swell. This makes the top sheet of steel no longer flat and the HPL pops off, especially in the corners. Nothing can repair swollen woodcore panels - they must be replaced. 

Using the IDC Submission Form Quote for Replacement Panels allows us to see the condition of the panels. Sometimes steel and concore panels de-laminate because the maintenance contractor uses too strong a solution of cleaning chemicals which migrate under the edge of the HPL and eventually eat away the glue. This is much less common than the problems with woodcore. We always suggest the customer use the IDC Submission Form Quote for Replacement Panels to send in photos so we can evaluate and suggest a solution for the problem. We also highly recommend the use of RISE Access Floor Cleaner to avoid harsh chemicals in the computer room. 

Occasionally we may encounter some resistance to the customer sending photos or replacing his or her panels. In that case, the customer's two options are screwing the corners and attempting to spot glue - neither of which will provide a permanent solution. If he attempts to spot glue then he will need to find a glue with a nozzle to push under the edge of the HPL - contact adhesive will not work in this case. He should try something like Liquid Nails and be sure to clean up any excess which oozes out immediately. Contact adhesive can only be used on clean panels and full sheets of HPL. It should be applied on both the panel surface and the back of the high pressure laminate, allowed to dry until tacky not sticky to the touch, and then the two surfaces are pressed together. The biggest issue with contact adhesive is the customer only gets one shot to get it right - the glue grabs immediately if allowed to dry properly and can't be re-positioned. Another reason to have AFS do re-lamination or replacements of any floor panels.
