I've really got to thank you for making this video. I have to make some stop sign shaped signs for someone. 18 of them in fact. I have a CNC router that I make signs with and I have never ever had any luck at all with any type of painting on MDF. I was happy to see the results of your remake on the Killz primer being rolled on. That really looks nice. So now I know what to use on my project, and believe me I wan't looking forward to the painting part as I have, like I said, never had any luck at all paining MDF. Thanks again buddy, I really appreciate this video. Jim
Thanks for the video. I will definitely try the Kilz 3 method. I've learned that with Rust-o-leum is that they mean when they say to apply additional coats within the first hour or else wait for 48. Otherwise, it causes a wrinkling in the paint and the only cure is to sand back to the wood and do it all over again. I've also used the R-O-L primer on wood and that works well, too, so long as you don't wait more than 1 hour to apply the color after. What an R-O-L operator told me was that I should also apply their clear coat within that first hour, too, after painting. But as you noted about how the paint doesn't quite layer right, who would want to finish that?! So, I strongly encourage anyone else watching this still, to wait the 48 hours dry time for the R-O-L paint before doing the final clear coat. You're the first one I've seen suggest using the Kilz, but I do like, from your video, the way it seemed much more "finished" compared to the other two methods. Thanks for doing this video.
Hello, I just purchased a computer desk online, and it's made of MDF boards. Yet these boards have a wood patterned wallpaper on top of it. Can I still use an Acrylic sealer to seal this?
Fot this demonstration I didn't, and for most projects I don't...but that also depends on the condition of the surfaces. On a cut edge I might just to even things out or get rid of any cut marks. On the faces not normally, since sanding roughens the surfaces and causes those little hairs to raise more when the Kilz soaks in.
I wouldn't think spackle would bond well enough to the mdf...like it would just kinda crumble and fall apart...maybe something like a sandable wood filler would be better. I used sandable wood filler to fix trim molding that my dog chewed (th-cam.com/video/0q9FPRWp-TM/w-d-xo.html),and that worked really well
@MoonBuiltGarage no that makes sense. Do you still prefer the kilz over the sanding sealer? I'm going to be doing a project soon and trying to decide weather to use a nice plywood or mdf. I'm going to be building a Nintendo switch cover for a TV
I do. I built a bathtub cover with shelves out of MDF, and used the Kilz to seal everything before painting, and everything turned out perfectly smooth
Best way I've found is to apply two coats of paint, between coat sand with 220 or 340 and recoat. Did some testing with a PVA wash at 75% glue to 25% water and got essentially the same results. I am in more of a production based application so minor imperfections are often overlooked. Would be filled with exuberant joy if time allowed me to BIN prime everything.

Glad the video helped!

I've found the Kilz to be the best at priming/prepping MDF for paint...it works really well at on the rough edges especially
Would have been nice to have seen the sanding sealer given the same TLC (roller application + sanding) as the Kilz primer for an accurate comparison
@4:01 I'm really impressed the sanding sealer didn't go everywhere as fast as you stirred! LOL (sarcasm at its worst)
You and me both!🤣
thanks man. peace and love to you and your family.
Thanks for watching!
You can buy hdf in a lot more dense

Probably not since it has something on the surface already, but if the edges aren't covered you may be able to seal the ends...
@@MoonBuiltGarage Thank you. that is what I thought.
Do you sand mdf before applying Kilz?
Fot this demonstration I didn't, and for most projects I don't...but that also depends on the condition of the surfaces. On a cut edge I might just to even things out or get rid of any cut marks. On the faces not normally, since sanding roughens the surfaces and causes those little hairs to raise more when the Kilz soaks in.
Auto filler primer works well. I've seen people use spackle on the edges then sanded.
I wouldn't think spackle would bond well enough to the mdf...like it would just kinda crumble and fall apart...maybe something like a sandable wood filler would be better. I used sandable wood filler to fix trim molding that my dog chewed (th-cam.com/video/0q9FPRWp-TM/w-d-xo.html),and that worked really well
Could you use sanding sealer first then a coat of the kilz?
Honestly...don't know. I feel that the sanding sealer might prevent the Kilz from adhering properly, but I could be wrong

Love your video! Excellent instructions and samples! Keep up the good work!
Thanks! And thanks for watching!

Is this water based paint or oil based ??
Thanks for this.
Hope it helps!
Zinseer BIN shellac primer.
So just to recap.
What are the steps to get the MDF baby butt smooth ???
Find someone to do it for you 🤣
Wow he asked a valid question and you just blow him off like that
The steps were pretty clear....if you don't like my answer maybe you could provide a more detailed explanation...

I have 60 doors and drawers in my kitchen that are MDF covered with Melamine. All of the Melamine is peeling.
That sucks! I've never been a fan melamine coverings
Or use pine.....
If you're going to use pine then why are you watching a video about painting MDF? But hey...thanks for watching!

Stopped watching as soon as the can came out.
Good for you....here's a cookie 🍪
So what can would you prefer to see come out?
