Painting

[Meat]

I've built spud guns before and I always have painted the PVC after it has been cemented and cured. I usually just lurk the forums, so I made an account just to post this question: Can I paint the separate parts before cementing them? It's probably yes, but I was wondering if the paint would do anything to upset the cementing process of the PVC... I could do a better job with individual parts, and I don't want it blowing up on me if the paint messes up the strength of the gun.

Keep the paint off the joints that you glue. The joint won't hold if you are gluing to paint. Simple masking tape on pipe and stuffing paper towels into sockets works for masking off areas to be glued. I presume you are trying to do something like this.

Yeah, basically, thanks

Glue, then paint. The reason pvc cement works is because it binds the plastic together and that wont happen if there is paint in the way

Or you could try dying it, I don't think that would interfere with the solvent welding process...

I think I'll just paint it after, I want two different colors, but I can mask it...


Thanks

Make sure you use a high quality plastic bonding enamel, or Rustoleum Professional Enamel, which I have found to work flawlessly for most any project.

Mask after the paint has fully cured. No need to have to repaint because you got impatience (like I do). Also I haven't personally tried it, but apparently Frog tape is the redbull of masking tapes. Blue painters tape is garbage.


On a side note, Meat, your avatar makes me smile.

Vinyl dye can be applied, then glued, and is also the best spray paint possible for plastics. Not kidding.
