Any of you guys use Kilz interior oil base spray sealer-primer on MDF? If so, how were the results.

I'm planning on sealing all cut edges with a 50/50 mix of Elmers glue and water, the trying several coats of the Kilz. After that, I want to use lacquer (several coats) on top.

If this plan is all screwy, please let me know, I'm not much of a paint guru.

Thanks, Tony
 
Water and MDF are not good companions. You may do more harm than good by trying to seal cut edges this way.
I suppose that if you've already got Kilz on hand, paid for, that's a strong argument in its favor, but it wouldn't be my first choice. I'm not sure how well lacquer will adhere to it.

Bondo works great on screw holes, and for filling or smoothing any gaps or roughness.

I have some particle board boxes that I am planning on spraying on the outside or inside (haven't decided yet) with Kilz to seal them. They are otherwise quite leaky/lossy.
 
just been building some furniture out of MDF for my new studio

sealed it first with a PVA/water mix and rubbed it down with a 600 grit then a 1200 grit paper

then sprayed it with a cellulose primer and top coat rubbed in between with 1200 grit

it's come out lovely and i'm really impressed

i figured it would be good practice for when i get some cabs knocked up and reckon with a bit of patience and several layers of laquer a piano finish could be achieved quite easily

i will say one thing though your final finish when spraying is entirely dependant on how good the original surface is ANY imperfections will show
