Hi guys, I’ve always read veneer both sides of a panel. I’m working on an old radio and need to veneer a piece of 1/4” mdf. I don’t have enough veneer in my shop currently. I do have some leftover Formica, can I use that on the back to act as my other veneer?

I think its acceptable especially if the piece
is going to be fastened down or captured
in a frame. I think an argument can be
made that it’s the glue more than the backing
veneer that keeps the substrate flat.

I would try it, personally.

No, Formica isn’t going to breathe or expand and contract like a layer of wood veneer. The point of veneering both sides is to maintain symmetry, both for symmetrical moisture changes and for symmetrical expansion and contraction from moisture.

For example, lets say the humidity rises and the veneer tries to expand. The Formica isn’t going to react to the moisture. So one side is trying to expand and the other is staying the same. Also, since moisture won’t go through the Formica, the underlying panel will absorb moisture more on one side. Forces will develop that try to bend the panel.

Now, is this actually going to be an issue? Who knows. It certainly is for things like cabinet doors where the panel is unsupported on only supported by a relatively flimsy frame. I think it would also likely be an issue for a large panel, even if the panel is firmly secured on all edges.

However, I get the idea that the pieces in the radio are likely pretty small and it probably wouldn’t matter much. But in that case, I would leave the Formica off. I think veneer on one side, and nothing on the other is better than putting Formica on the other side.

”I think veneer on one side, and nothing on the other is better than putting Formica on the other side”.

My thoughts also, Depending on the size and where it’s going.

Thanks for the replies, the panel is 18”X11”, two rectangle holes in the center of it. I have three screws on the left and right sides. The bottom and top I could probably sandwich something to hold it tight. I wouldn’t have time to get veneer tomorrow and want to move forward but didn’t want to screw myself down the road.
