Laminate edgebanding on HPL cabinets2/21
When we have a HPL job to do we apply the edging to the face of the cabinet with a edgebander. We are using 3/4" MDF core melamine. The problem we are having is the edging not wanting to stick. We have tried priming the back of the laminate but still have the problem once in a while. Any suggestions? or clues to what could be happening?
search the laminating forum. there are many ideas/suggestions there.
I don't use MDF for that reason PB core is easier to glue to. HPL is harder to get a good bond on also Some use a primer on the HPL.
We have banded with a lot of HPL and have found that a light spray of contact cement is the best primer on the HPL. Also make sure to blow off any fine dust on the MDF edges.
HPL can be contaminated with the release agent but priming usually takes care of that. We use Dorus primer. We avoid HPL for banding as much as possible. PVC is a lot better. As for the MDF, assuming everything is setup correctly it bands fine.
We edgeband a lot of material with laminate, all we do is prime the laminate first and don't usually have any issues. Like Michael said make sure your edges are clean. I talked to a tech from Homag as I have a Brandt edgebander and he said most edgebanding problems were caused by either, improper glue distribution, an edge that isn't square or an edge that isn't straight. I would maybe check all those things also.
