I know it’s not a good idea in general to face glue 1/8” thick exotic wood veneer (waterfall sapele) onto MDF due to seasonal wood movement.

However, if I want to veneer strips of MDF that are only 1-1/2” wide x 12” long? Meaning I want to cover the both 1-1/2” x 12” sides with 1/8”-thick veneer, so that the veneer grain runs along the long dimension. Is it safe to assume that the hardwood wouldn’t move enough to cause problems if it’s only an inch and a half across the grain?

It’s for a really shallow box sides to be finished with shellac and poly.

Any comment would be greatly appreciated!
Best wishes, h.

Thinner veneer would be better. 1/16” would be fine. 1/8” might be but you’re pushing it IMHO. I used to like MDF for veneered boxes but now much prefer B.B. plywood. .... just my opinion.

Thanks, Shipwright! Will try to sand some veneer off to make it thinner. Do you mean that even a 1-1/2” wide strip veneered onto MDF may crack/warp eventually?

Paul – For someone who has a veneering project coming up and who hasn’t yet decided between an mdf and a plywood substrate would you be willing to expound on your preference for ply?

harum, The glue can control the bottom of the veneer but the thicker it gets, the less control it has over the top. I know 1/16 will be fine. Maybe 1/8 will be too but more risk.

JAD, I use hide glue. One of the reasons is that it is reversible with heat and water. If you need to do that on an MDF base, the base will start to soften and turn to mush. Otherwise I don’t have a problem with it but that’s a big one for me.

Baltic birch is the prefered material when veneers are to be applied. I agree with the others that 1/16” thick veneer is better than 1/8”. Why do professionals use MDF? because the material is cheap

Thanks for the reply Paul – I’d forgotten about this thread. I’m planning on using hide glue so that is good to know. Thanks.
