I have been asked to paint a smiley face on a big 'ol dark grey field stone. Anyone have any thoughts on whether enamels or acrylic latex would adhere and last better. Should the painted area be primed! My thought was to go with acrylic latex, one coat primer, probably two coats bright yellow and black outline and features. Anyone foresee any problems or can suggest a better option?

Marty
Dan Sawatzky swears by the use of just a good acrylic paint....
Hope that helps...maybe he can jump in and clarify further.

Thanks Robert,
I recall Dan recommending acrylic latex on concrete work but I was just wondering if anyone had anything to say about painting on good 'ol 'geological substrate'. I expect after eons a rock is stable enough to accept anything properly applied to it.

15 or so years ago when I got drafted as the craft material procurement director for the girl scout summer camp, my wife was directing. I used liquitex acrylic paint. on the rocks powerwashed them with a mix of tri sodium phosate wall cleaner by dirtex in the local paint dept, at the big box stores. it slightly ecthes the surface so the paint can bite. the ones floating around in the house still look sharp and bright. a couple outside lasted 4 or 5 years before starting to fad. As a side note to answer about oil paint 18 years ago I was with a rail musum. I sprayed an Alco locomotive with Sears best oil based house paint. the paint was a donation. Washed the loco with the samw stuff. Cranked up the loco and used the air brake air, reduced to 65 psi and nailed the paint to said loco. Used kerosene as the thinner 70/30 paint to kerosene. can out great seen the loco, a month ago and it now is starting to fad and chalk.
Good luck, don't let the greenies see you do it, Posted by R T Thomas (Member # 355) on :
Marty, I've airbrushed many a rock using airbrush acrylics and clearing with a rattle can clear afterwards. They seem to hold up real nice once they've had time to cure a while. I'm talking river rocks here. Not sure if the field stone is made of the same stuff, but it's still just a rock. Acrylics should work fine. Hope this helps, R.T.

I believe I would prime said rock with XIM, then give it one good coat of Oneshot, preferrably chrome yellow since its so hard a pigment. Lemon probably would look more sunny, but it doesn't cover as well for me...may need that second coat.
Acrylics would work OK.... so would your method. For me personally, I would find my method faster and easier. Regards,Jeff

Clean real good and paint with a QUALITY artist acrylic.
Have some buried at a friends house...9 years ago...still looking good. Used CelVinyl Paint.

I would use a 15 or 25 year rated 100% acrylic latex house paint. The thing I would probably check to see first is if I needed to put a primer down. If I felt I needed the primer, then I would use "KILLS 2" with a little of the finish color mixed in with it to possible prevent a second coating of the finish color.

Six years ago I sandblasted 84 rocks for golf tee yardage markers. They get watered every day and are left out year 'round. I played golf there a couple weeks ago and they still looked great.
After sandblasting I simply gave them one coat of One Shot lettering enamel straight out of the can. Of course after sandblasting the numbers, the area to be painted was very clean.

Hey Dave Sherby, I've been wanting to get into blasting rocks too and so far have only dome granite and marble. What type of rocks were they?

Acrylics should work fine.
