hot glue

[kathleenfen]

Hi All,

Odd little question for this morning. I need to paint on hot glue (after it's cooled of course). I'd like to hear suggestions anyone has for choice of paint to use on it. I'm concerned with long-term adhesion, other than that, I don't care what type of paint it is.

Thanks,

Kathleen

Hello Kathleen,
I also use hot glue a lot for casting - I use acrylic paints with some success tho it is hard to apply the first coats. I'm looking for a way to clean or prime the glue to accept the paint better

I've also used thick acrylic paints in the tube on dried hot glue. Worked pretty good on craft projects. :)

There is a "paint for plastic" now available in hardware stores.

I have not yet tried it, but it should be worth exploring. I was thinking more of resin cast things, but it may adhere to the dried glue as well.

The main limitation will be a limited range of colours. Which can be overcome by mixing, as with artist colours.

Actually, yes. I find the "enamel" paint in the same format has better coverage for one coat, but an experiment yesterday showed that the thick acrylic paint goes on pretty good too - useful as a primer.

i.e., the stuff in tubes not bottles, not liquid, very thick and viscous.

I remember seeing ( a long time ago somewhere) a suggestion that a surface be coated with spray adhesive & then it would more readily accept acrylic paints. Never tried it, but it's an interesting idea for a primer or intermediary. I guess a light coating, not like coating with rubber cement (frisket?).

I always wondered if that would work.. I gotta try it

I've had more success using the "enamel" paints and with very thick "oil style" acrylic paints. The watery dollar store ones of course do not cover.

They also sell spray-paint type primer for plastics. Maybe this would help as an undercoat for an acrylic or enamel to stick to. Haven't tried it, just an idea.

Confirmation:

Thick acrylic paints (oil style) will adhere nicely to hot glue castings. Liquid dollar-store watercolor-style ones not so well.

Good morning, Bonjour, Buenas Dias, Buon Giorno, etc:
Excuse my ignorance but what in hell is Hot Glue casting? Sculpture is really cast in this stuff? Any size? What kind of glue? What brand? Enlighten me please.

You know what a glue gun is? THat's 'hot glue' - it makes a very simple, very faithful and very durable casting material (it is, after all, not glue but simply melted plastic)

You inject it into the mold, preferably a rubber one, and wait till it cools. You can cast extremely fast with hot glue, faster even than plaster, and the positive can have undercuts and small details all will faithfully be reproduced. The positive is flexible and durable, can be dropped, flung around. I have a gargoyle with wings and arms on my keychain and it gets tossed into bags and knocked around and it's about 5-6 years old.

It's well worth experimenting with.

I mainly use it for small castings, but I have used it for stuff as large as 1' x 1' approximately.
