Question

Painting on Silicone


I attached a thin board with Marine Adhesive Sealant to an iron gate that is across my front porch...for some privacy on the porch.. only covered lower half of iron gate.
my friend had me attach this board with this adhesive. I want to paint the board and the gate black.. but this I think is silicone ...
What can I do to get rust-oleum black gloss paint to stick to the silicone adhesive.. The adhesive is white.
Will a Primer cover it and if a primer will work, which is the best to use..

thank you
Barbara

Was it 3M 5200?
Nothings going to stick to silicone.

If it is pure silicone, no choice but to remove it. For interior applications, I will sometimes just caulk over it with acrylic and paint. I wouldn't do that outside or anywhere that gets weather, abuse, or wear because even acrylic caulk won't really bond to it, it just dries on top giving you a paintable surface.

I've used CoverStain from Zinsser in situations like this. I'm not guaranteeing a long term "paint stick" but it will last for a few years, maybe more.

Zinsser BIN can work like that too. I think what happens is a quick drying oil/shellac primer can dry and hold its film integrity even if it isn't really bonded in places (over the silicon). In other words, they dry before they have time to separate.

Yeah it should. Just realize that the primer won't actually be stuck to the silicone, just dried on top of it. Like Gym said, it might last a good while but you could scratch it off with your fingernail.

If you go that route, watch the areas where the silicone is right after you prime. If it starts to separate, brush it back together. If its not too cool or humid, it will dry quickly and hold together.

5200 is not silicone.
Great stuff if you use it for what it's made for, not for what you used it for.
Got a picture?
Any way to scrape off the access with a razor blade?
There is a product called Debond that claims it will remove it.
Google "3M 5200 remover"

Painting on Silicone


I know it is a marine adhesive... I was trying to put something on the bottom of my gate ... wanted a metal plate welded on but couldn't find anyone to do it for me... my friend said something about screwing on a plate with self tapping screws for metal... but for me .. hard to do... I asked someone to do it ... but never happened... so my friend suggested putting it on with the marine adhesive..said it would hold it on there forever... so I got the marine adhesive and a thin board and glued it to the iron gate... now I want to paint it black.. the board and the iron gate. I definitely wasnt' too neat getting it on and in place... put clamps on and let it dry for 24 hours.
I was concerned it might not stay on but my friend says it will.. he has used the marine adhesive before.. so I went with it...
Right now, the clamps are off and it's holding...
I'll take pic and post
thanks

The 3m page says its a polyurethane sealant. You would think you could paint it with something. Can't seem to pull up a spec sheet on it though.
