How do you avoid paint bleeding under tape??


What's the trick to prevent the paint from bleeding under the tape when painting foam (GWS).

I'm using the blue painters tape.

This hasn't been a problem in the past but now it is. I'm using the same paint and tape as before.

Spray on real thin coats of paint! Take many light coats instead of a thick one!

Bleeding


You're right, I was kind of horsing the paint on this time instead of multiple light coats.

Thanks for the wake up call.

after applying your blue tape for stripes I thin down polycrylic and brush 2 coats over the tape line.....this will prevent bleeding under the tape......

use a nicer, high quality trimming tape and then lay your masking tape over that. make sure you mask it off just before you are going to spray and make sure its down well, use thin layers, or hit it once w/ clear....that way you cant see the bleed :-)

Thanks guys, I lik the idea of the polycrylic over the tape before the color.

One other way is to lay down your tape, then spray a light coat of the adjacent color along the edge of where you plan to paint the new color. Let it dry, then apply the new color. Any paint that bled through will match the adjacent color. Just another way to skin the cat . Good luck, Dzl

Good tape (haven't had any luck with the blue painters tape) and pull the tape off immediately after you spray. Works for me everytime. Paint bleeds through as it's drying. Not immediately when sprayed. Thin coats.

What is "Good Tape" ??

I always use Scotch brand now. I've had it with cheap masking tape.

I clean with alcohol before applying the tape. I run my fingernail along the edge to "seal" it. After I spray, i arrange the object so that when drying, gravity pulls the paint AWAY from the tape.

I got some masking tape at Hobby Lobby (craft store) that was in the model department for plastic cars. Works great on wood and foam (isn't that sticky) but Ledbetter was right. Any name brand high quality tape usually works.

I use el-cheap-o electric tape. Blot it on my shirt a few times to cut down the tack. There MAY be some bleeding if I go heavy, but good enough for me

IMO the blue 3m tape is the best----it leaves no residue and comes off w/o pulling off other layers.

they key to getting a good clean line is to first mask off w/ some VERY thin ( 1/8" width or so, depending on application) speciatlity tape. Then overlay your masking tape and paper layer. Its also impt to pull it off soon after your last coat.
