|Sanded tile grout pavement in place. Note the subtle variations in color and texture in the "older" pavement on the left. This was done by "stirring in" small amounts of darker and earth-tone grout when still dry.
Since I built the basic benchwork going on three years ago, the town of Enosburg Falls, which is right up front when one comes down the stairs into the basement, has remained a partially scenicked, half done repository for stand in structures, surplus rolling stock and an assortment of tools and modeling supplies. And that's on top of the layout!
Getting the underside of the layout looking presentable was step one. The next item on the to-do list was to get the top of the railroad cleared off and at the very least ballast the track and install the roads.
I won't elaborate on ballasting the track. I used pretty standard techniques. One thing I'll add about ballasting - a little ballast goes a LONG way, and too much ballast can reduce a well running layout to an engine stalling, derail inducing, mess. So when you ballast track use about half the ballast you think you need - and be especially careful with it around turnouts!
I've tried all types of methods to make roads in the past. For smooth paved roads I think styrene may make be the best choice. But in this case I was looking to create an older, faded somewhat rough road. I tried Ceramic Stucco texture - which I've used with some success on building foundations - but that stuff is pricey. I also tried AK Interactive asphalt and concrete texture. I found the texture just a little too gritty for HO scale (it's great in larger scales) and if you think the artist medium like the Ceramic Stucco is expensive, just wait until you see the price for a very small tub of the AK stuff!
|Oyster Gray - much lighter
than it appeared on the label.
I went to Home Depot and ended up with two bags of sanded grout - one was a light gray color called Oyster Gray, the other a very dark gray (almost black) called Charcoal.
Since neither color looked right I started combining them together. I worried I'd get a "salt and pepper" effect but frankly the stuff is fine enough that it really blended into a single color.

Applying it is simple. I put masking tape to mark the width of the road and create a sharp transition from paved to unpaved areas. After mixing the grout to the desired color apply it dry to the area of the layout you want to pave. Then use a disposable foam brush to smooth the grout. I noticed the lighter gray grout tended to have clumps - these were easy to break up during the smoothing process.You can introduce subtle changes in the pavement color by manipulating the dry grout with the foam brush. You can also add more dark or light gray grout as desired. I even tossed a small amount of earth toned grout into the mix to warm up the pavement slightly.
The last step is to secure the pavement in place. For this mist the grout with a mixture of alcohol and water (about 25% alcohol/75% water). Start with a gentle mist to "lock" the grout in place and then completely soak it. The next day it will be rock hard.
In other news, I also started working in the basic landforms in the Berkshire area. Old magazines make great weights to hold the foam in place as the glue dries!
