Paint help please.

Paint help please.
I have put together some railway buildings from the company Home which are made of resin & I am really pleased with them. But most will house electronics & a light to shine through the windows. So I run bathroom silicone sealant around all the joints on the inside to waterproof the buildings. I now notice the light is shining through the resin that the buildings are made of. No problem, I will spray the inside black. But the acrylic paint won't stick to the silicone sealer very well. Any suggestions. IE: a certain primer.

May not help this time, but maybe use the brown outdoor stuff for sealing round door and window frames.

Do a test with this first, just in case there is a reaction between the various paints and adhesives..

If it is silicon then paint will not adhere to it, on the tube it will say "Will Not Paint" or similar. So what ever you apply will peel. If you want to paint a sealant you need to use acrylic based sealant.

... bathroom silicone sealant around all the joints on the inside ...

take any kind of tape. duct-tape, scotch tape, or whatever, that is wide enough to cover the silicone and some of the resin.
then paint or spray.
its on the inside, so who cares, on what the colour sticks.
