"Sticky spray-paint" Topic

Yesterday I spray-painted some plastic figures for undercoating, but the paint stays sticky. Could it be I didn't shake well?

The paint is supposed to be professional grafitti paint, so it should be quality?

Any ideas what to do and how to prevent it?

Professional grafitti paint????

…whatever next? College degrees in vandalism?

<<…whatever next? College degrees in vandalism?>>

Pretty much any degree from Ohio State qualifies.

As for the sticky spray paint, perhaps the paint is reacting with the plastic? I ahve never seen that except with spray tool dip, which is actually a rubber coating. Maybe you can spray a regular primer over it?

Listen to Craig – an MSU Grad knows a thing or two about vandalism. "Win we burn a couch, lose we burn a couch, it's all good" Although I do agree with his assesment of OSU.

With respect to the paint – paint drying time is affected by temperature and humidity. If it is cool and wet where you are you may want to wait a longer time to make sure or put a fan on it. Don't be in too much of a rush to give up and make it worse. Rather than spray over it if it stays tacky I would strip it and start over.

Professional graffiti paint? Methinks you missed the point of PRIMER.

Primer paint is designed for a specific purpose… to create "tooth" on a surface that is otherwise smooth. Using any other sort of paint for your primer is pointless… it simple won't adhere to the model as well. Your model will be more prone to chipping without a proper primer.

That said, check you can of graffiti paint… what are the drying times listed in the directions?

Given that it probably designed as an outer layer paint that will be exposed to the elements, I imagine it has a pretty slow drying time to allow a bonding seal for resistance to weather conditions… probably 2 days for a full dry.

Additionally, it's expecting a surface with a lot of tooth, like brick and masonry. Don't expect it to hold to your lead very well.

I think Steve gave you the best advice… strip it and start over… with paint designed to be primer.

I'd strip and start over as well…

If the spray paint is enamel based and depending on your humidity and tempurature conditions it could take a couple of days to fully dry and not be sticky to the touch.

I would suggest using a an acrylic based primer like Games Workshop or some other similar product (there are a couple other good ones out there I just don't remember their names off the top of my head).

I'd go with acrylic too it tends to be more flexible than enamel once dry and with the best will in the world plastic figures will flex in use.

Rather than "grafitti paint" it's not that never-dry security paint designed to ruin the trousers of ne'er-do-wells is it? ;o)
