So I'm gonna be a painting a sign on a brick wall. I just talked to the guy who not only cleaned and preped the wall, he also put a oil based seal coat on the brick wall. I was going to prime the wall using Jay cooke's Sign primer. Yes or not?

So insead of a "Primer" I could use say, Chromatic White background enamel for the base. I have a few gallons of Chromatic background enamel. I do want to put down a white base do the painted lettering/graphic will have a nice bright look to it.

My suggestion would be to let him find out what kind of primer is compatible with the sealer he used, that puts the ball in his park if there is a failure. Personally I don't like the sounds of "an oil based seal coat". Brick is porous and absorbs moisture and any moisture that gets in is now going to be trapped behind that oil base coat and I suspect will eventually peel. An acrylic or latex will breathe and allow the moisture to escape.

All of the Walldog murals now are done with water base NovaColor which is a GREAT waterbase paint acrylic. It holds up like iron as far we have experienced.

most of my experience with latex paint is on porous brick/block/stucco...it does not penetrate any more then just the surface..sorta lays there. and the vehicle(water) EVAPORATES from the outside in. oil base on the other hand sinks into any porous product.....dries from the inside out......hence it take a while to dry)))

I am no expert on the topic....BUT....I think Jane IS an expert on this particular topic.
I'd go with her opinion/recommendation.
Joe..I have seen, close up, how well an oil based sealer works on brick, concrete block and cement walls. It doesn't. BUT it IS easy to remove after it starts blistering and peeling!!!

Sorry Opie, but when it comes to any type of masonry, latex paint will far outlast any type of enamel. Come on up, and I will be happy to take you out and show you a couple of signs I painted 26 years ago with Sherwin-Williams Superpaint Latex. Both of them, and many others painted since still look good today.
My only problem with Latex paint is I don't get to do as many repaints.

OP, I painted my concrete block basement walls 28 years ago with plain old Sears latex house paint. A few areas just started wearing off a couple years ago. Overall it still looks good. It lasted much longer than the paint on my wood siding.
Alicia, I'm not sure what the product is that they used but the Theater Board that I am on was investigating a sealer for the brick fly over the stage. It is sprayed on and completely seals the brick, even small holes. I do onot know the paint compatibility of this stuff but I think you are on the right track to investigate what they used and go from there.
