Glue sizing...? or if its called that? - Scroll Saw Woodworking & Crafts Message Board

Hello guys, new to forum and look forward to getting some info.

Well i finished a car audio speaker enclosure and when i painted it, the edges on the outside (where I cut it AND on the routered edges) soaked up the paint alot and i had to apply 4-5 coats just to fix it so it looks even... What is out there so I can fix this problem so that it all goes on even the first or second coat without soaking up on the edges?

I'v heard about 50% water and 50% glue and mixing it up and applying to the edges? would that work? what is an inexpensive fix for this?

also, titebond II is used FYI

Thanks everyone!

The glue mixture should work, but be sure to let it dry well before painting it or you will get a crackle effect.

You could also use a sanding sealer, or any clear finish that you have on hand.

Theresa is right....And welcome to the family.

Ok great! So I would be able to use 50% titebond II and 50% water, mix it well, apply it, let dry completely then paint would go on well?

Thanks!

Probably will work fine for painting but not staining.

Just to be sure I'd try it on the edge grain of a piece of scrap first...

Ok. what is straining?

I'd actually suggest a white glue instead of Tightbond II. Tightbond II has a bit of water resistance built into it, but white glue will dissolve in water.

To be honest, 50/50 PVA and Water, wont do any better job than a good quality water based undercoat/sealer.
We have a 3 in one Undercoat/ sealer/primer it aint cheap, but it does the job. I'm sure you could find a similar product locally.

Being a Car audio system, I'd hazard a guess that you used MDF. The machined edges have to be sanded really well, down to about 240g.
