MDF Sealer Recommendations


Does MDF sealer make a difference and if so can you recommend a good quality brand


I used shellac because it is not water based and won’t cause the MDF to swell and I had it laying around. It worked well, not sure if it is needed or not, if you use tape for work holding it will stop the tape from pulling up bits of the MDF every time you peel it up. I suspect any non water based product would be a good choice.

I used an oil based primer when I built my office (made by Kilz), but I have also used water based acrylic without any problems. Given all the issues using oil-based products, if I do it again, I’d use water-based paint for everything. 0.02
