I just tried gluing up a quick sample joint using biscuits and RooClear on 5/8" melamine. The two pieces were about 10"x16", with the joint along the longer dimension.
The joint was a 90 degree "L" with the edge of one piece joined to the melamine face of the other. I put the glue on the edge of the one piece and in both sets of biscuit slots, then clamped the two pieces together at about the same pressure I would use with yellow glue and plywood. I left the piece to dry at room temperature for about 18 hrs.
I then tried breaking open the joint for testing purposes. The joint broke when the biscuits pulled out of the edge (rather than the face), taking some of the particle board with them.
However, the real problem is that it appears that the particle-board/melamine bond was basically non-existant (there are no particles stuck to the melamine).
Anyone have any ideas why it failed? Other comments on this glue have said that it would pull the melamine off the face rather than fail at the glue line.
I'm re-trying the joint with no biscuits, just glue. Have to say that I'm not very impressed so far.
I've emailed the manufacturer to get their comments.
