John.....

I'm leaning for #8.... but...

It also depends on the local soil color..........Dirt blows onto stuff and adds color to the original concrete color.

Then of course there is the color of the grease, soot, and coal detritus that falls from the upper deck.

No one said that any of this was simple......

And we do this for fun  ! ! ! !

I like #5.  Do you take the picture under your layout lighting?  That can effect the color as well.

Thanks for the input.  I will post the processes that I used and what my eyes think, this evening. I will be adding lots of weathering once they are in place and supporting the trestle. This little experiment has me looking at lots of concrete the past couple of days.

Thanks for the input Jeff.  Yes - the lighting over my workbench is the same as over the layout.  I'll post more on this tonight.

I also did a test paint of the footings for the trestle.  Which painting process do you think looks the most like an old concrete footing?





I will post the painting process that goes with each number once I see what kind of feedback I get.

I'm leaning between 7 and 8.

John....

One more thing...........  Wood bent trestles that sat on concrete usually had some sort of saddle that was cast into the concrete and then the bents clevis bolted to them during the construction of the bridge.  Don't forget rust stains from those saddles.

And consider putting drippings of creosote that come out of the wood in the heat of the first few summers in service.

Thanks for the input - I will post how I did each one when I get to a keyboard - I'm typing on a cell phone waiting for a oil change.

Thanks Bob

The trestle bents I'm modeling have a sill plate with anchor bolts into the concrete.

I'm with the consensus, I think.  5 or 8.

Thanks Dave


I'm going to go get my notes and post the process for each one.

[S&S RR]

So here is the process I used for each of the samples, with a few comments.






1) Floquil - Aged Concrete Paint over white hydrocal casting. I have never seen concrete this color - just sayin.


2) MicroLux Acrylic - Aged Concrete Paint over white hydrocal casting. MicroLux did a great job of matching floquil color,  but see number one.


3) Number 2 process with an additional wash of 2 tablespoon to the pint A&I wash. Still doesn't look right - to much yellow.


4) Floquil Concrete paint over white hydrocal.  Looks just like fresh concrete that I could still put my hand print in.  Not what I'm looking for.


5) Raw hydrocal casting with 2 pinches - the way Grandma taught me - of charcoal color tint mixed into the wet hydrocal. The color goes completely through these castings - if you chip it or break it the color is the same. My choice too.  But I wanted to see if you guys agreed before I make a couple hundred of them.


6) Number 5 with a 2 tablespoon to the pint A&I wash - too dark.


7) Raw hydrocal casting with 1 pinch of charcoal color tint mixed into the wet hydrocal. This color to me makes the concrete look look older - lighter in color.
White hydrocal with a 2 tablespoon to the pint A&I wash. I liked this when I first did it but I believe the color will fade away with time.  It reminds me of the hydrocal rock castings on my first layout - I used washes to color the castings - they looked great for about 6 months and then gradually the color faded away until they completely washed out and needed to be recolored. They are now holding up the mountains of my new layout - I used acrylic paints to paint everything on this layout (see past posts).


I really like the looks of the hydrocal castings with the powdered tints. I will be using tints for all my structure castings in the future - even when I plan on painting over them.  I have made some stone and brick wall castings, sidewalks, and roads and really like how they look.  I will post pictures after they have dried for a few days.





The products I used.

John......

My favorite is the Floquil aged concrete.  It has a little green in it and when dusted with a little of the dirt of your choice on you pike makes it look really great.

Thanx

I spend a lot of time looking and taken pictures - it keeps me out of trouble.
