Have any of you run strips of HPL through your edgebander? I've got a project where that would be really helpful but I have heard mixed things about it - like bands starting to pop loose after install. I'm just using regular EVA glue. Anything special to prep the panel edge or back side of strips?
I have successfully done this using Dorus KS 217 which is also an EVA glue. The thing to remember is the back of the HPL needs to be primed in order for it to adhere to the glue. Someone may chime in with a better solution, but I used wood glue diluted 1:1 with water as a primer, and it worked like a charm. As always, run some tests before your production run.
Russel is correct on what to do. Brush on primer do not spray. PUR glue is the best solution. Getting matching 3ml PVC is the way to go if you ask me.
Any banding that falls off will not show up for months sometimes.
This has put companies out of business, be careful.
We use spray grade contact cement to prime laminate strips with success
Purchase the primer, we use the Dorus brand and never have issue. Spray (brush or roll is ok also) the whole sheet of laminate before you cut into strips. Dries quickly and is not tacky when dry.
Phil B why not spray, we have been spraying for years?
Another vote for PVA primmer. PVA wood glue, same thing some laminate guys use for "hard seams", works well for both laminate and thick wood banding. Why would anyone choose to use a creepy glue that only makes sense in very limited circumstances?
Image tests were done with end trimmers off and the overhanging ends slammed against a counter.
We also use the Dorus primer for both HPL & wood. We spray full sheets.
Thanks for your input! Can you also use PVA solution (watered down yellow glue) and the Dorus for oily wood bandings like teak?
