Painting Concrete

Joe- Great post! I'll try your method of starting with the red. For our architectural models we use primaryily latex flat house paint colors applied with a Pasche airbrush. We usually prime with a light coat of Krylon gray primer. Three or four airbrushed coats of a light base color is what we start with.  Our go to base color is B-M 1521. To add color texture, we "spritz "- overspray over the work,  allowing the paint droplets to rain down. Typically at least one darker and one lighter color are used. Our latest shadowbox brick has six spritzes on top of the base color. As you suggest, modification can be made at the end, even overspraying with the original base color, if needed.

Thanks and also you reminded me - the last two coats (dark gray and light gray) are indeed sprayed from about 12 inches to add texture to the concrete.

Very very AWLful nice!!!  Have to try that on my next bridge.

Thank you very much. I constantly struggle with "concrete" color....I must have over 12 different samples I am trying right now and still am not happy.

Let's not even start on getting my "rock" color correct! 

I may add, what also works for me is a final spray of India Ink and rubbing alcohol spritzed on but it takes a little practice to get the technique.

Thanks again, I will give your process a try.

I am wondering what brand and type of paint do you generally use?

I'll have to try that and see how it looks. What I've been doing and works and looks great is brush my sidewalks, driveways, etc. with Model Master aged concrete, then mist spray a light gray using a rattle can bought at Wal Mart. Let it dry then give it a wash with black acrylic to bring out the details. Later I brush some black, Dark Grey, chalk in various heavy used areas.

Joe,

   Great building process for nice concrete, real nice work Joe!

Either Krylon or Rust-Oleum rattle cans - does not make any difference other than the Krylon spray is easier to control than the 2X Rust-Oleum. The red oxide is actually the ACE hardware brand since it was the cheapest.
