Any Problem doing acrylic art painting on Tarpaulin

[Merlion]

I am new to this Forum as I normally do oil paintings. Recently I am given many old outdoor buntings and wonder if I could do art paintings on the back surface for outdoor display. The material seems to be canvas tarpaulins. While the front is relatively smooth, the back surface has serrations and may be able to grip paints better.

As i am planning to do art painting, I would like to try artist acrylic paints, and not acrylic wall paints. I am not doing large mural paintings.

I have done simple trial tests and notice the surface does grip the acrylic art paints. Of course i cannot be sure of what happens in the long term.

One of my questions is whether artist acrylic colors are all right outdoor, against the sun and rain, say for a few years. I am not worried about snow.

Another question is whether anybody has tried using these plastic canvas tarpaulins as support surface for acrylic paintings. Do they continue to grip long term without peeling off?
