I have a short stack about 6.75 inches (9 layers) of stacked mdf for a smallish speaker. I want to seal the layers and sand and then laminate over the layers, so that the layers are smoothed and not visible. Then either paint or veneer over the laminate. The mdf face would not be laminated, just the sides where they are stacked.
I am hoping to use heat lock adhesive for the laminate and zinser bin sanding sealer.
1. Can I use sanding sealer, sand and then Lanie over it using heat lock adhesive?
2. Should I seal the inside of the layers, this of course needs to be done before I put the end cap face layer mdf on. Can I use some sort of rubber coating on the inside like flex seal or red seal?
3. Would you suggest something else?
