Paint, Acrylic, and Aging
I am doing a project where I need to paint onto clear
material. I would use glass but it is too heavy; I have tried some
acrylics but the paint cracks over time. I have put the material once
painted onto the acrylic and heated it at low temperature for 3 days in
the oven at very low heat.
Is there any substance I can put onto the acrylic to help the paint stick
and not crack off over time.
Is there any way to duplicate sun exposure and heat to see the effects of
Why reproduce the sun?
What would be wrong to exposing to the sun, the issue usually is rain, but
you should be able to monitor that action. The sun bleaches so the colors
may fade. There are sprays that seal. Cracking is usually from bending, or
the drying. Oil paints cracked from the drying of the oil. The bending
means you have to attach to something like glass, plastic is lighter.
Apparently you want to have a transparency so there is another option, take a
picture of your final, the film being transparent, you lose something but now
the problem is touching up. You might get so good effects. One normally not
considered is to work on the reverse side, you get some 3Dish effects. The
lesson from all this should be "always work backwards" work from the final,
how will it be used, what do you want etc.
